DIY solar technology has been improving at a rapid pace but EG4 has been on the bleeding edge over the past 3 years and their products outperform other bigger names like Tesla at way less than half the cost. They’ve made it possible for many folks to build solar systems that enable their homes to run off solar 24/7. We started out with a small EG4 inverter and expanded it into a system that took us off the grid. Amazing. Thank you James and everyone else at SS for constantly pushing the envelope with home solar technology!
I fucking love these guys. They are a whole generation of product ahead of everyone else. Maybe more with the manual bypass, seriously they have thought of everything as I could see doing it. Keep up the good work! Next time you guys have a charity project out of the states let us know, we would love to join and help out. We work all of the toughest AHJs in the NW. These products simplifies and lowers the cost on so much switch gear we previously needed to supply for 200A or even 60A bypasses.
I would love for EG4 to have independent installers trained. I would love to buy a system but there are no local installers I can find in the Northern VA area.
Just got my license in WV. Gotta reciprocate in VA, but I'd love to start a conversation if you're interested. I have run the battery operations at the two premier installers in VA for the past few years and am really excited about what EG4 cooked up.
@SignatureSolar your products are definitely on the top of my list for future off grid situations....right now though I need to power an off grid trailer....i have narrowed it down to an Ecoflow dura 3, Anker Solix f3800, or Mango 5000. For the 50amp capabilities.
This totally blows the Sol-ark out if the water guys! I have been waiting for exact solution that is NOT proprietary on the GridBoss switching! My next customer scenario is main meter and 4 loads in main panel is 60 ft from sub panel with most house circuits in sub panel. The wiring and conduit alone would have been well over $4-6k for electrician to run 200 amp “loop”. No need for loop anymore.
I have a very similar setup. I am trying to learn enough to get this setup going with a handful of panels until I replace the roof. It's pretty overwhelming even with a good understanding of residential electrical.
@idahoduckhunter from what I understand. Before you wanted 18kpv hooked up with full capability utilizing 200 amp grid Passthru u would have to run 200amp (4/0, expensive) cable to the 18kpv then to you main panel. This doesn't even include the transfer switch/shut off switch required before the 18kpv but after meter that is expensive to install. With this grid boss it is rated for service entrance meaning it can be primary disconnect so saves you from having to install another disconnect, then you are also saving money on cable costs since now u just need 70amp cable from 18kpv/flexboss to gridboss. this also allows you to also relocate the batteries with 18kpv to a shed or other place on property and not have to be within 20ft of meter (because 200amp copper is expensive, and now only need 70amp copper) with the 200 amp disconnect being separated from inverter makes it easier for electrician or DIY to piece together a kit. So you can start by adding grid boss, then can add inverter/18kpv with. Batteries afterwards.
I need a setup/demo video comparing and contrasting potential on grid setups with this vs the 12 and 18k. He makes fair points with less conduit and wiring but I’m not sold. If you see it as next level then please build it, demonstrate, and compare real-world numbers.
Please consider releasing a meter collar controlled by the Gridboss. That would IMMENSELY simplify installation. A meter collar would mean zero mods to the heritage service panel.
I have a question on the GridBoss. Our meter can is next to two 200-amp manual disconnects (one for house and the other for 40x60 shop). The 200-amp house critical loads panel is approx. 125 feet from the meter can and the 200-amp shop panel is approx. 95 feet from the meter can. Ideally, we would like to back up the critical loads in the house (perhaps lights in the shop as well). The part we are not sure about is how to utilize the smart ports to shed loads if the Gridboss is that far away from the Critical loads panel without incurring a large expense for wiring. It is our understanding that the GB should be near the meter to also limit wiring expense. This would allow the FB21 and batteries to be placed almost anywhere (within cable limits) using one 70 amp wire and communication cabling. Your thoughts?
Hello! This would be best answered by our design team! If you'd like to reach out to us at 903-441-2090, we can get you connected with a specialist to assist!
RE: Firmware, are we able to update it online using wifi or in the app, or do we need to hook up a laptop and communicate using a serial cable? It would be nice to be able to do everything via the app.
That was a ton of information, thank you for that interview! With the one wire system and all of the sensors and logic, can you now do load-side AC coupling? i.e. microinverter panels on your garage that can back-feed to your gridboss at your house
Also love hearing that 6 flexbosses and 2 gridbosses can share a battery bank! Makes it so simple to create your own 400 amp system, with 400 amp becoming more normal especially with a bigger home and a garage/shop
Thanks for the video. Do I understand it correctly that the Grid/Flex combo requires fewer external components and associated labor? Does it bring the total cost of the system closer to one based on the 18KPV?
Gridboss looks great! Please compare/contrast with Franklin, Anker and Enphase offerings! Please figure out how to connect the 240 V 30A outlet from a Ford Lightning or Chevy Silverado EV to run light loads at night and recharge the permanent batteries if there was not sufficient solar during the day while in a grid outage. It would be great to plug in a nice looking battery stack like Anker, Briggs and Stratton (think EcoFlow ultra) with an Inverter on top of these stacks to minimize costs and wall space.
3:57 wait, is this apples and oranges? my utility requires a blade-type (not breaker style) service disconnect outside at the meter. (ask me how i know. 😡) it doesn't look like the gridboss has that style ac disco. also it looks like folk are mounting the gridboss inside the house not outside near the meter so it's not accessible to the utility (as mine requires). so it seems you'd still need an ac disco anyway? also regarding a manual bypass switch, i use mine to switch the house between grid or the inverter so that if the inverter croaks, i can switch the house back to grid. i guess you've put that in the gridboss (?) but if the gridboss croaks, you're still stuck right? (just trying to understand the differences to just using a whole house 18kpv setup.)
Correct me if I'm wrong but you stated 5 MPPTs that they are labeled 1+ 1- 1+ 1- 2+ 2- 2+ 2- 3+ 3- . This means the dual 1 and 2 inputs are where you can parallel 2 strings meaning it's only 3 MPPTs. Odd nothing I've seen comes close to Tesla's Powerwall 3 six MPPTs.
Thank you for your message. To clarify, starting at 15:03 through about 15:10, James mentioned: "we up the amperage just a little bit more so we can handle five full strings..." James did not specify five MPPTs. You are correct, however, in that the system features three MPPTs, with the first two MPPTs having dual inputs, allowing for the parallel connection of two strings each. This is in contrast to Tesla’s Powerwall 3, which includes six MPPTs. I hope this clears up any confusion, and feel free to reach out if you need further clarification.
I have recently purchased 2 18kpvs and 6 indoor wall batteries and 60 390watt panels from signature solar. I already have 10,080 watt system hooked up with no batteries. Will remove that inverter and hook the panels to one of the 18ks. I would think the the grid boss would simplify this instal? And are you going to make a video on wiring the grid boss to the 2 18kpvs and multiple/6 for me wall batteries? Thank you for all you have done for us diy guys!
I realize that not many people are affected by this but I live at 8,500ft in the Rockies and the altitude limit is 2,000m or about 6,500ft. Does this void the warranty and is there any way to install these units at 8,500ft?
Please share what that PV disconnect does? Is that meant to take place of a separate/dedicated PV disconnect that would normally sit between panels and inverter?
It's more like a 30-50% home back up because I have a Tesla (12KW), 5KW AC, Pool and branch circuits. If I have to spend $6K to get 12KW, may as well get a 60KW Solis 3P or $8k 100KW. Anyone with similar situation be aware.
13:00 how would sharing a battery bank work with communication? If there is only one master battery that can speak to only one inverter, can the grid boss systems talk to each other? Or how do both systems know what the SOC is?
I keep having inverters still in the box when the next generation comes out. I don’t need this system but it seems like a good option when building the electric service on new construction.
Loving this, in theory could you have someone install the grid boss first and this flex boss inverter at a later date? Mainly thinking about avoiding grid power electrical and then diying the solar portion. Also on the generator input, would a eg4 charge verter still be recommended for most cheaper generator when using Flexboss and gridboss
The FlexBOSS21 looks like just what I need. By chance is it able to communicate with a Span smart breaker panel for shedding? If not could it in the future?
I have an existing micro-inverter based solar install and a 24kw gas generator connected to the grid. I want to add a 48V battery backup for overnight.
I'm running into the exact run away cost problem with my SolArk 15k. Local installer wants $11k for a disconnect, transfer switch, AC coupling, wiring and labor. Not including inverter or batteries...
What inverter product does EG4 have that is legal in California and can be installed between the meter and branch circuit breakers such that grid can be fed to the breakers when no solar or battery are available, but solar or battery are not fed back to the grid? My understanding is that some inverters do this but not at the absolute 100% "no back feed" level that is required. Also, there is proper industry vocabulary for these issues, product functions, and perhaps you can fill me in. Thx!
A question. I am having 42 solar panels on a barn roof connect directly to my meter and the grid at the farm house. The meter is on 400amp box, which goes to two 200amp breaker panels in two different locations. If I bought an EG4 FlexBoss21 with a GridBoss for each 200amp breaker panel, how do I connect both GridBoss to the solar panels? I want to be able to use the solar energy from the solar panels to run my house and or charge the batteries if the grid goes down.
Im not an electrician but I believe you would run your solar panels (PV) to the FlexBOSS21s. The FlexBOSS21s would connect to batteries and GridBOSSes. Each GridBOSS would connect to a separate 200 breaker panel and to the grid (meter).
Can the flex boss not export to the grid on its own? Is it possible to limit the current to the grid[boss]? Ie, if you already have a 25A line run across your house?
@@dougbertInExileif you had a battery in a garage under the flex boss but meter is 200’ away on a pole, could the grid boss still be in the garage where the main panel is (all that is on the pole is a meter and a 200Amp breaker)
Is it possible to configure a delay for the Smart Ports on the GridBOSS? I’d like to ensure a graceful shutdown of my HVAC condenser to prevent any potential damage (by HomeAssistant automation turning off the compressor in case of power loss).
Yes, it is possible to configure a delay for the Smart Ports on the GridBOSS. The gridboss itself doesn't support delays on it's smartports, but If you're already using Home Assistant, you can create an automation that detects power loss or a grid outage through the Gridboss. The automation can then include a time delay before turning off your HVAC compressor or any other critical devices.
@@DirectSolarPower Well, the approach you're suggesting is not going to work, because if you configure the GridBOSS to shed power from the HVAC unit on power loss, it will do so within milliseconds and Home Assistant automation won't have time to kick in...
EG4, if you're listening, your next innovation should have a DC smart port with an EVSE addon. This would enable DC charging to an EV bypassing any need for an inverter and conversion losses. 🙏🏽
Oh man this would be a game changer! Unfortunately your question is way ahead of its time! On a side note if you can dc charge at home it is natively bi directional!
@paullind6534 I understand where you're coming from. However I hope EG4 isn't thinking this way. We've been DC charging batteries for decades. Nothing has changed. 😔
@ Agreed! Communication with every ev manufacturer is a real challenge. Not just physically but also legally due to things like warranties and such. Manufacturers could easily detect a dc discharge and program it to kill the circuit. Charging might be a thing but discharge not so much😞
I am building a new house. Would it be possible to have a grid boss installed during construction to prepare for future solar/battery install that may be a year or two in the future.
I am sold and ready to install this on my home in Northlake TX but I cant find an electrician willing to install the system. Does anyone have a recommendation?
I'm looking at the online manuals for the Gridboss and Flexboss21 and it looks like the only way they can connect to the outside for monitoring/updates etc.. is via WiFi. Is it possible to use copper ethernet to connect to them if you don't HAVE a good WiFi signal where they're to be installed?
I’m interested in more of these integrated smart breakers in your off grid focused inverters. I’d love to dump all excess solar through an electric boiler to put additional heat into my slab foundation or run multiple mini splits at certain states of charge. The newer smart load centers don’t do much for us off grid guys if they arnt talking to our batteries.
Can GridBoss be used with a 100amp breaker, only see CSR2200N in the specs? Want to feed 100amp from main panel to grid boss that now goes to a sub panel. This will allow me to backup all critical loads in sub panel as well as have smart loads (EV, water heater, etc). Can't sell back here so will only use in off grid mode but the flexibility of the grid-boss makes setup and expansion so much easier.
I have a Generac whole home generator with an auto-transfer switch. Is that compatible with the grid boss or would the auto-transfer switch need to be removed?
I wonder about this as well. I currently have Generac with ATF and a Solark 15k. I split them apart because the solark would try to sell to grid when grid was disconnect by Generac ATF.
Seems like it could be good for a small off-grid place. Based on James' comments, I think a grid-tie 400a service would be much more difficult with it. Probably better with 18kPVs and SPAN.
Oh no! That's okay! The video will be posted to our RUclips page after and you can ask any other questions you may have in the comments and we will do our best to answer them!
You need to teach electricians installers how to do your installs have free classes or low cost classes make it worth the installers to learn . You can sell so many more units if you can get lots of installers trained . So many places don’t have any installers to hire to get your system installed. Please work on teaching installers how to install your units so you can sell tons more units . Many people can’t buy your systems because there’s no one to install them .
Hi! Here are the STANDARDS AND CERTIFICATIONS for the Flex Boss.( UL1741, SA, SB, PCS CRD California Rule 21 Phase I, II, III Arc-Fault Circuit Interrupter (AFCI) NEC 2020:690.11/UL1699B Ground Fault Monitoring (GFDI) NEC 2020:690.41(B) CSA 22.2.107.1:2016 Ed. 4 CSA 22.2.330:2017 Ed. 1 IEEE 1547.1:2020; IEEE 1547:2018 Hawaii Rule 14H [HECO SRD IEEE 1547.1-2020 Ed. 2] Rapid Shutdown (RSD) NEC 2020:690.12 FCC Part 15, Class B (PENDING).
It’s like you split the 18KPV into two components, boosted the power a bit and gave it a new name. Not that there is anything wrong with that!! I kind of like the idea of having one component on the wall better than two.
For those of us who dont have room at or near the Grid in (meter) and need to place the inverter and batteries in a garage that is 100 feet away this is a great solution. Don't have to loop 200 amps. I can install the GridBOSS at the meter and FlexBOSS21 in the garage with batteries. Only need to run Flexboss21 output to the GridBOSS. Plus you get rid of a bunch of different components that are built into the GridBoss. Easier and cleaner install.
Yes, there would be one set of AC cables between the inverter and GridBoss. The max supported wire size is from 6AWG and 2AWG, so you would not be able to use the 2/0.
@EG4 is the absolute best in the biz!!!! These guys are doing it right and we’re moving their products like it’s going out of style. 🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻 Keep it up fellas!
The tariffs on China have been in place Since Trump first put them in. Biden did not delete them. Turn off the mainstream and get better news bro. It will be just fine.
Because thats basically what the EG4 18kPV is. If you need multiple inverters then you a paying multiple times over for a transfer switch you don't need. By separating them you get more flexibility and are only paying for what you need. Like in my case I have to install inverter and batteries in the garage that is over 100ft from the meter (grid-in). If I use an inverter that has a built in 200 amp transfer switch I would have to loop 200 amps over 100 feet each way. That a huge cost. With the Gridboss I would only need to run a single 6awg wire from the FlexBOSS21 to the GridBOSS.
Hi! We recommend hiring a licensed electrician experienced in solar installations to ensure everything is set up correctly and safely. As for internet connectivity, it’s not always required for the system to work, but having internet allows for better monitoring and access to advanced features, like remote diagnostics and performance tracking. If you have more questions, let us know!
Wait, the three hybrid inverter ports only work with EG4 inverters? That is a huge bummer. If it worked with existing installations (Enphase or other) the GridBoss would start a whole new and really useful niche by itself. A smart transfer switch for all sources: grid, generator, EG4, or existing inverters, and load shedding.
HOW ABOUT A PROGRAMABLE DUMP LOAD TO EV CHARGER SO WHEN EVERY THING IS CHARGED AND STILL HAVE GOOD SOLAR RESORCE IT WOULD THEN TRIGER THE EV CHARGER ON?
Hello, are you often troubled by inconvenient wiring and high installation costs when setting up inverters or energy storage systems? Our LoRa module supports wireless communication, making it easy to connect to any RS485 Modbus RTU device. Additionally, we offer a LoRa wireless energy meter that pairs perfectly with it! If you're interested in reliable wireless solutions, please feel free to reach out to us.
It is exciting for EG4 and me, however, SRP in AZ does NOT care. They insist on their external transfer switches and meters. I have 3 meters on my how with a Sol-Ark, which like the EG4 Gridbox or teh EG418kw have the built in the transfer ability. Again, SRP refuses to rely on these products. They want to meter everything and have their own switches. Otherwise, I think the new products are great..

I guess I'm at a loss in the cost savings and complexity world. It still feels to me that the main point of all this tech is to be off grid. So I'm not clear why adding complexity and cost.
This is a great setup for those of us that are grid tied and also need to place inverter and batteries in a garage over 100ft from the meter. They just came out with the 12000XP... may be a better solution for simple off-grid needs.

You are correct, however, in that the system features three MPPTs, with the first two MPPTs having dual inputs, allowing for the parallel connection of two strings each. This is in contrast to Tesla’s Powerwall 3, which includes six MPPTs.
I hope this clears up any confusion, and feel free to reach out if you need further clarification.
I have recently purchased 2 18kpvs and 6 indoor wall batteries and 60 390watt panels from signature solar. I already have 10,080 watt system hooked up with no batteries. Will remove that inverter and hook the panels to one of the 18ks. I would think the the grid boss would simplify this instal? And are you going to make a video on wiring the grid boss to the 2 18kpvs and multiple/6 for me wall batteries?
Thank you for all you have done for us diy guys!
It would definitely simplify the install! We don't have it planned but we will take it into consideration, thank you for the suggestion!
I realize that not many people are affected by this but I live at 8,500ft in the Rockies and the altitude limit is 2,000m or about 6,500ft. Does this void the warranty and is there any way to install these units at 8,500ft?
Thats a good question
Does your home panel have to be 200 Amp? And how much can be back fed into the public grid with hybrid inverter ? More with 200amp service?
Please share what that PV disconnect does? Is that meant to take place of a separate/dedicated PV disconnect that would normally sit between panels and inverter?
It just cuts off the PV. It can take place of a seperate one but some local municipalities do require a seperate one.
It's more like a 30-50% home back up because I have a Tesla (12KW), 5KW AC, Pool and branch circuits. If I have to spend $6K to get 12KW, may as well get a 60KW Solis 3P or $8k 100KW. Anyone with similar situation be aware.
13:00 how would sharing a battery bank work with communication? If there is only one master battery that can speak to only one inverter, can the grid boss systems talk to each other? Or how do both systems know what the SOC is?
Nice! I’m glad I didn’t start my solar project yet…👍👍
I keep having inverters still in the box when the next generation comes out. I don’t need this system but it seems like a good option when building the electric service on new construction.
Do I need to build a little shed to put this in? Or should I just put it directly on the side of my house?
Yes, this is NEMA 4X rated, it does not need to be inside.
Should I buy and install the grid boss first before I buy the flex boss 21?
Yes, it can bypass until you want to install the inverter
Amazing product line
Loving this, in theory could you have someone install the grid boss first and this flex boss inverter at a later date? Mainly thinking about avoiding grid power electrical and then diying the solar portion. Also on the generator input, would a eg4 charge verter still be recommended for most cheaper generator when using Flexboss and gridboss
Yes, it can bypass until you want to install the inverter.
Good stuff EG4
The FlexBOSS21 looks like just what I need. By chance is it able to communicate with a Span smart breaker panel for shedding? If not could it in the future?
I have an existing micro-inverter based solar install and a 24kw gas generator connected to the grid. I want to add a 48V battery backup for overnight.
I'm running into the exact run away cost problem with my SolArk 15k. Local installer wants $11k for a disconnect, transfer switch, AC coupling, wiring and labor. Not including inverter or batteries...
What inverter product does EG4 have that is legal in California and can be installed between the meter and branch circuit breakers such that grid can be fed to the breakers when no solar or battery are available, but solar or battery are not fed back to the grid? My understanding is that some inverters do this but not at the absolute 100% "no back feed" level that is required. Also, there is proper industry vocabulary for these issues, product functions, and perhaps you can fill me in. Thx!
A question. I am having 42 solar panels on a barn roof connect directly to my meter and the grid at the farm house. The meter is on 400amp box, which goes to two 200amp breaker panels in two different locations. If I bought an EG4 FlexBoss21 with a GridBoss for each 200amp breaker panel, how do I connect both GridBoss to the solar panels? I want to be able to use the solar energy from the solar panels to run my house and or charge the batteries if the grid goes down.
Im not an electrician but I believe you would run your solar panels (PV) to the FlexBOSS21s. The FlexBOSS21s would connect to batteries and GridBOSSes. Each GridBOSS would connect to a separate 200 breaker panel and to the grid (meter).
Can the flex boss not export to the grid on its own? Is it possible to limit the current to the grid[boss]? Ie, if you already have a 25A line run across your house?
Do I need to add EG4 Battery Chargers for Darkstart?
I knew I was waiting for some reason
Is it a stand alone inbeeter other then the batteries or do i have to buy charge controllers and all that other stuff
You don't need separate charge controllers.
Last part about batteries being anywhere? Because you can move the inverter?
batteries are close to inverters (usually within 10 ft) but the GRID line is a 6 awg and you can run that much longer
@@dougbertInExileif you had a battery in a garage under the flex boss but meter is 200’ away on a pole, could the grid boss still be in the garage where the main panel is (all that is on the pole is a meter and a 200Amp breaker)
Is it possible to configure a delay for the Smart Ports on the GridBOSS? I’d like to ensure a graceful shutdown of my HVAC condenser to prevent any potential damage (by HomeAssistant automation turning off the compressor in case of power loss).
Yes, it is possible to configure a delay for the Smart Ports on the GridBOSS.
The gridboss itself doesn't support delays on it's smartports, but If you're already using Home Assistant, you can create an automation that detects power loss or a grid outage through the Gridboss. The automation can then include a time delay before turning off your HVAC compressor or any other critical devices.
@@DirectSolarPower Well, the approach you're suggesting is not going to work, because if you configure the GridBOSS to shed power from the HVAC unit on power loss, it will do so within milliseconds and Home Assistant automation won't have time to kick in...
EG4, if you're listening, your next innovation should have a DC smart port with an EVSE addon. This would enable DC charging to an EV bypassing any need for an inverter and conversion losses. 🙏🏽
Oh man this would be a game changer! Unfortunately your question is way ahead of its time! On a side note if you can dc charge at home it is natively bi directional!
@paullind6534 I understand where you're coming from. However I hope EG4 isn't thinking this way. We've been DC charging batteries for decades. Nothing has changed. 😔
@ Agreed! Communication with every ev manufacturer is a real challenge. Not just physically but also legally due to things like warranties and such. Manufacturers could easily detect a dc discharge and program it to kill the circuit. Charging might be a thing but discharge not so much😞
@paullind6534 I'm good with just DC charging. :D
The spec is important for locations that use these inverters for UPS without solar (apartments, condos, etc)
Signature solar number #1
I am building a new house. Would it be possible to have a grid boss installed during construction to prepare for future solar/battery install that may be a year or two in the future.
Great idea
Yes!
Thanks 👍
I am sold and ready to install this on my home in Northlake TX but I cant find an electrician willing to install the system. Does anyone have a recommendation?
Hi! If you'd like to reach out to us at engagement@signaturesolar.com with your zip code, we may be able to help locate an installer in your area!
after 30 years with my photon harvesters, this great new tech solves SO many problems. Love it and a great video, keep going
Thank you @norsk54472
I'm looking at the online manuals for the Gridboss and Flexboss21 and it looks like the only way they can connect to the outside for monitoring/updates etc.. is via WiFi. Is it possible to use copper ethernet to connect to them if you don't HAVE a good WiFi signal where they're to be installed?
We offer an ethernet dongle for this, without this dongle there is no way to hard wire.
@@SignatureSolar Good to know, thanks!
You're so welcome!
A+
Thank you so much for your feedback!
Will Gridboss work with other Eg4 hybrid inverters? like 12kpv or 18kpv?
yep, just those
@emillianoruiz7681 Yes, both the 18kPV and the 12kPV!
I’m interested in more of these integrated smart breakers in your off grid focused inverters. I’d love to dump all excess solar through an electric boiler to put additional heat into my slab foundation or run multiple mini splits at certain states of charge. The newer smart load centers don’t do much for us off grid guys if they arnt talking to our batteries.
Can GridBoss be used with a 100amp breaker, only see CSR2200N in the specs? Want to feed 100amp from main panel to grid boss that now goes to a sub panel. This will allow me to backup all critical loads in sub panel as well as have smart loads (EV, water heater, etc). Can't sell back here so will only use in off grid mode but the flexibility of the grid-boss makes setup and expansion so much easier.
Do these products work with the LuxPower 18kpv labelled inverter in Canada? Luxpower LXP-LB-US (18KPV) 12k Hybrid Inverter
Are flexboss and GridBOSS outdoor rated?
Yes
Yes, the outdoor rating is NEMA 3R on the GridBOSS and NEMA 4X on the FLEXBOSS21.
Is the boss rated for outdoor
yes
Yes! The GridBOSS is rated NEMA 3R and the FLEXBOSS21 is rated NEMA 4X.
So let me get this right, the flexboss21 replaces the 12 or 18 K inverters?
The FlexBOSS21 is an alternate option, yes!
I have a Generac whole home generator with an auto-transfer switch. Is that compatible with the grid boss or would the auto-transfer switch need to be removed?
I wonder about this as well. I currently have Generac with ATF and a Solark 15k. I split them apart because the solark would try to sell to grid when grid was disconnect by Generac ATF.
No need, you can connect your generator to your GridBOSS :)
Will GridBoss and FlexBoss have EMP protection?
EG4 has not released any documentation regarding this at this time.
Seems like it could be good for a small off-grid place. Based on James' comments, I think a grid-tie 400a service would be much more difficult with it. Probably better with 18kPVs and SPAN.
I've got a meeting at the same time y'all are live 😭
Oh no! That's okay! The video will be posted to our RUclips page after and you can ask any other questions you may have in the comments and we will do our best to answer them!
You need to teach electricians installers how to do your installs have free classes or low cost classes make it worth the installers to learn . You can sell so many more units if you can get lots of installers trained . So many places don’t have any installers to hire to get your system installed. Please work on teaching installers how to install your units so you can sell tons more units . Many people can’t buy your systems because there’s no one to install them .
AC coupling only works with eg4 inverters? No solaredge or ephase?
Works with those too
When will the FlexBoss 21 be CEC listed?
Hi!
Here are the STANDARDS AND CERTIFICATIONS for the Flex Boss.( UL1741, SA, SB, PCS CRD California Rule 21 Phase I, II, III Arc-Fault Circuit Interrupter (AFCI) NEC 2020:690.11/UL1699B Ground Fault Monitoring (GFDI) NEC 2020:690.41(B) CSA 22.2.107.1:2016 Ed. 4 CSA 22.2.330:2017 Ed. 1 IEEE 1547.1:2020; IEEE 1547:2018 Hawaii Rule 14H [HECO SRD IEEE 1547.1-2020 Ed. 2] Rapid Shutdown (RSD) NEC 2020:690.12 FCC Part 15, Class B (PENDING).
Why would you droop the screen??? I do not use WiFi and apps that connect to a Chinese server.
The screen is sold separately - You can order it here! signaturesolar.com/eg4-flexboss21-lcd-screen-kit/
It’s like you split the 18KPV into two components, boosted the power a bit and gave it a new name. Not that there is anything wrong with that!! I kind of like the idea of having one component on the wall better than two.
For those of us who dont have room at or near the Grid in (meter) and need to place the inverter and batteries in a garage that is 100 feet away this is a great solution. Don't have to loop 200 amps. I can install the GridBOSS at the meter and FlexBOSS21 in the garage with batteries. Only need to run Flexboss21 output to the GridBOSS. Plus you get rid of a bunch of different components that are built into the GridBoss. Easier and cleaner install.
Are these units weather proof like the 18K?
Yes this is NEMA 3R rated
He does mean 1) set of wires between flex and grid, right? I’ll be using 2/0 cu.
Yes, there would be one set of AC cables between the inverter and GridBoss. The max supported wire size is from 6AWG and 2AWG, so you would not be able to use the 2/0.
What is the idle consumption for the Boss
Under 30 watts.
Do you have any free samples?
When my grid boss arrives I will give it to you for free. Shipping or pickup will cost 4K😊
Where are these manufactured?
When is a simple grid tie inverter coming like the new Growatt??
Like the EG4 18kPV?
It sounds like u can mix a flex21 and a 18k. But not sure.
Yup
@EG4 is the absolute best in the biz!!!! These guys are doing it right and we’re moving their products like it’s going out of style. 🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻
Keep it up fellas!
Thank you! And congratulations!
Cool!
What’s the benefit of this over the Schneider ‘BCS’?
cost
@@dougbertInExile so all the features are otherwise exactly the same? That seems weird they would only copy and not have any extra features.
Are you saying grid boss allows one flex boss and two 12k’s?
GridBOSS has 3 hybrid inverter inputs. They must be EG4 tho.
@ can they be different models of eg4 was my question
@@Hamsquatch1973I believe they addressed this in one of their videos. Must be 12kPv, 18kPV, or FlexBOSS21 and they can be intermixed.
I'm concerned about these tariffs in 2025. Hopefully the industry is working to get an exception.
The tariffs on China have been in place Since Trump first put them in. Biden did not delete them. Turn off the mainstream and get better news bro. It will be just fine.
I just don’t understand why not 200 amp transfer switch on the flex boss
Because thats basically what the EG4 18kPV is. If you need multiple inverters then you a paying multiple times over for a transfer switch you don't need. By separating them you get more flexibility and are only paying for what you need. Like in my case I have to install inverter and batteries in the garage that is over 100ft from the meter (grid-in). If I use an inverter that has a built in 200 amp transfer switch I would have to loop 200 amps over 100 feet each way. That a huge cost. With the Gridboss I would only need to run a single 6awg wire from the FlexBOSS21 to the GridBOSS.
So who is going to install these things to make sure a homeowner wont screw something up .and does this have to have internet in order to work
Hi! We recommend hiring a licensed electrician experienced in solar installations to ensure everything is set up correctly and safely. As for internet connectivity, it’s not always required for the system to work, but having internet allows for better monitoring and access to advanced features, like remote diagnostics and performance tracking. If you have more questions, let us know!
Wait, the three hybrid inverter ports only work with EG4 inverters? That is a huge bummer. If it worked with existing installations (Enphase or other) the GridBoss would start a whole new and really useful niche by itself. A smart transfer switch for all sources: grid, generator, EG4, or existing inverters, and load shedding.
It can ac couple existing systems
Through the smart breakers, but not through the hybrid inverter ports. See his statement at about 28:10.

HOW ABOUT A PROGRAMABLE DUMP LOAD TO EV CHARGER SO WHEN EVERY THING IS CHARGED AND STILL HAVE GOOD SOLAR RESORCE IT WOULD THEN TRIGER THE EV CHARGER ON?
Or trigger water heater when there excess solar or full battery. He basically said the smart loads was to keep from over loading the inverter
Smart Load ports
I wana run 3 flex boss 21 threw one grid boss.. living dangerous
Hello, are you often troubled by inconvenient wiring and high installation costs when setting up inverters or energy storage systems? Our LoRa module supports wireless communication, making it easy to connect to any RS485 Modbus RTU device. Additionally, we offer a LoRa wireless energy meter that pairs perfectly with it! If you're interested in reliable wireless solutions, please feel free to reach out to us.
It is exciting for EG4 and me, however, SRP in AZ does NOT care. They insist on their external transfer switches and meters. I have 3 meters on my how with a Sol-Ark, which like the EG4 Gridbox or teh EG418kw have the built in the transfer ability. Again, SRP refuses to rely on these products. They want to meter everything and have their own switches.
Otherwise, I think the new products are great..
Will look into SRP compliance
@@jamesshowalter6362 What about CEC compliance for California?

@ thank you for this information!
I guess I'm at a loss in the cost savings and complexity world. It still feels to me that the main point of all this tech is to be off grid. So I'm not clear why adding complexity and cost.
This is a great setup for those of us that are grid tied and also need to place inverter and batteries in a garage over 100ft from the meter. They just came out with the 12000XP... may be a better solution for simple off-grid needs.
