awesome I installed one with a power pro battery for my friend here in puerto rico. he has a 5hp well pump and it works great powers the well pump and the house without any problems going on for almost three months now. he is of grid as well
Nice!. Yeah I’ve talked with quite a few people that are going with solar in Puerto Rico. The 18kpv was a solid choice. It’s a beast when it comes to inductive loads.
Do it while they have the promo going. The warranty is amazing and customer service has always been amazing for me. I had a 6500ex and now have the 6000xp and will be buying an 18k for another project soon.
Thanks for posting! Looking at installing a 12Kpv based system on a new home. The metrics for the whole year really helps me sanity check my estimates and assumptions.

Really good ideas here. My wife has been saying I need to include this type of content in a video. I need to put that on my list. That’s exciting about your system! You’ll love having your own power plant.
I have the system as well in Colorado. I’m grid tied but can be self sustained most of the year. My home is all electric as well and I can attest. It’s a great system and a fantastic inverter. 14kw solar, 30kw battery
Nice! Still looking at installing maybe a couple of these this fall, along with additional batteries and maybe some more panels. Really good to see this kind of feedback. And congrats on your continued growth of subscribers!
We currently have 2 rich solar inverters at 6000 each. Neither are working. We have honestly had the worst luck with our system! We r looking at getting one of these with some ruixu arteries, since one battery is 314ah, my question is, what is your battery storage capacity for your size house? We are about the same size. Thanks!
@@Nunya-biz-ness We have 12 - 100a EG4 Lifepower batteries. That's two racks of six. We're going to add at least 6 more so that will give us a total of 90+ kWh of battery storage. That will be enough most of the time, but really cold days will still require using the chargeverter to cover the load. Especially if it's multiple days of cloudy when it's cold. You just can't produce enough. If you over paneled by a lot and also had a ton more batteries it's technically doable but it's not practical for a few days a year. Currently we have two MPP Solar 6500 inverters and they have worked flawlessly for almost two years. I just feel like they're probably not going to last 10 years so I want to replace them now before I have problems. One of those learn as you go kind of things, but I'm learning. 🙂 Good luck!
They have really been doing great. They had to increase their staff and get things caught up. But now I’ve been getting a lot of positive feedback about them.
"It works, and it makes power" is exactly what I want to hear. We're looking to add batteries to our existing microinverter system and refuse to buy anything else from Enphase. The 18Kpv is a very tempting unit.
Do you have a video with a diagram how you set it up? I’m curious what your connections from the meter coming in to the unit look like, and then going out to your subpanel..
Just download the manual for this and other competitive products like Sol-Ark. there are good drawings in there with many different examples of installation scenarios.
Gavin, Thanks for the videos! I see you have an option to show the battery details in the on line tool. I have looked and can't find that option . Can you share what firmware you are on for the 18K and for the batteries? Thx JP
The 18kpv firmware 1A1A is the latest. But I’m still on 1919. And whatever the latest battery firmware is. This applies to the LL V2 and above, and pro battery versions. If you have them then you should be able to get the same data on the EG4 monitor site.
Hi, i just get this inverter at my home but i'm gonna need some help, i have the grid conection directly to the inverter and i can charge the batteries but i can't use the load output, do you any idea of what i can do? Its really necesary to put a main swicth panel?
I mean, I dont Want to make the auxiliary switching, its any way to make the inverter just chargue when they need and let the load output use the grid, I hope yo can understood what i want to do
@@GavinStoneDIY i already read the manual but its the first time that i work with this type of inverter, can you helpme searching the page or what manual did you use because i can't find that part, well find exactly what i need
@ maybe watch more videos on it. Essentially the 18kpv is capable of grid interactive features. So technically you don’t need a critical loads panel with this inverter. It can power your grid panel directly.
Hey. Maybe you can help me with a question about the WiFi dongle for the 6000xp. I don't have internet available at the moment at my homestead. I'll be getting maybe Starlink in the future, but need to get a setup to power everything first. If i don't have internet, how can I do firmware updates, change settings, or monitor things with the 6000xp? Thanks
You can always change settings on the inverter itself. But it does have a local connection option. Do have cellular service there? Signature Solar has a cellular dongle you can purchase as well. That’s what I’ve been using. If you’re not, you can download the firmware on your phone, and upload it via the “local connection” option on the dongle.
Hello Gavin, thanks for your input. So, I just installed my 18kPV with one indoor wall mount battery and 3200 W array for an aux bldg. Everything is working as expected but, the unit gets purdy warm (110 deg F) on the face cover around the EG4 logo. Is this normal?
The fans are temperature reactive. So if it’s too warm the unit will take care of itself. It also has passive cooling since the heat rises out of the top. I don’t remember the last time I checked with a camera. Doesn’t sound too high to me. But you could always verify all your PV and battery connections are tight. Oh you mean by the upper label? Yeah it’s a bit warm there as the heat rises.
@@GavinStoneDIY Thanks. I agree with you. I think it might be a normal operating temp. I'm waiting on SignatureSolar to call me back. I set up an oscilating fan and it dropped the temp a little ( down to 104 defg F). thanks again
Hello Gavin, I have a question, can you run two 18Kpv's off of one 15000Ah. battery bank and your guess for how long at daily 45kwh usage a day thank you Tim
@@thewind-ne8rh ahh I see. Well you can figure up your usage by a little math with total kw usage vs the amount of storage you have. But yes you can use the same battery bank for both inverters. The easiest way would be to install a central busbar and split off from there.
With the 6500ex at certain inverter output, usually low output, the house lights will "flicker". Once the output increases, like turn on more lights or using vacuum or toaster the flicker stops but returns when the output drops again. Have you noticed any flickering in your lights at low output?
No I haven’t. The only flicker I’ve seen occasionally is when a large inductive load kicks on. But that’s typical of any inverter. This inverter is way ahead of the 6500’s on design and functionality.
Great video. I'm designing a system and may use this same inverter. I also plan to be off-grid, so I have a question. How does the EG4 18K unit handle all the solar energy if your batteries are full and your loads are very low?
If the batteries are full and there isn’t any need for power then the inverter just doesn’t use the power from the panels. The power from solar is essentially pulled, not pushed. So the inverter has to request the power from the panels, is the easiest way to think about it.
Ah ok, so you must have the 70 amp breaker in your house subpanel, and then you have another critical loads panel in addition to that? If that’s the case, did you need a critical loads subpanel in addition to your whole house subpanel for some reason? Someone suggested you can just have it connected at the a 70 amp breaker from the panel, and not even need the critical loads subpanel. How did you get your two hvac systems running with just the 70 amp breakers?
You technically don’t need a critical loads panel with this inverter because it can interact with the grid. But I already had all of that setup from the previous system. The hvac doesn’t really pull that much amperage if your install an easy start on them. At least for the air conditioning. The heat does pull a lot of amperage, but I don’t use that because I have a wood stove.
Curious what batteries you’re using that are showing individually on the 18kpv remote screen? I have lifepower4 units and they don’t show(they just work)
@@nathandeboer7974 it’s available on the remote screen as long as you have the hub. It just takes a firmware update on the batteries and hub. Check EG4’s latest firmware updates.
Do these have L1, L2 current transformers (or are they available) to use with on-grid so the 18Kpv will supply the house loads (almost all) but not back feed into the grid?
In the spring I usually am around 75-80% SoC in the morning. So we don’t really have far to charge. It’s a slow climb after a day or two of rain though.
They have different tones. But they are similar noise level at full PV input. But considering the 18kpv only turns its fans on at 6kw or over, it’s definitely all around quieter yes. And if you were to add 2 XP’s to reach the same output power as the 18kpv then it’ll certainly be quieter.
Gavin great video new to solar I use an average od 50kw a day with a well pump od 1hp not looking to sell to grid however I would like to pull from grid automaticly when needed is this the unit for me
This, or 2-EG4 6000xp’s. If you aren’t needing to export to the grid then an off grid inverter like the 6000xp will likely work for you. Plus you have redundancy if one unit goes down you’d still have power. Then again, a lot of people like to have everything in one box. And you really can’t go wrong with the 18kpv. It handles loads extremely well, and runs smoothly.
Energy consumption is listed as kilowatt-hours. KWh Power is kilowatts. kW Otherwise you might be purchasing a water pump that produces 50 psi per day. 😂
What's your total battery capacity on the 18Kpv, since you mentioned being fully charged by around 11am? Just curious, since you have a lot of solar feeding it.
I have around 500v input on input #1 and #2. Input #3 has 280v I believe. Those are my arrays. But if you’re asking what each input is capable of as far as voltage, it’s 600v max on each independent input.
Hey great video on your 1st year anniversary. We are doing our first 6 months. A question for you .Where are your CTs located, by your meter or inside the inverter ?
Enjoy your videos! Thanks I don't know where you are located, but you obviously have been through winter. I'm in the far north Idaho. How do you deal with low sun, clouds, snow? Generator, grid power? How large is you battery rack...kWh?? You said that you are off grid or running as if off grid....and that you have wood heat. I installed a "critical loads panel" and moved most of the largest loads (heatpumps, oven, dryer, etc.) to this panel. I guess that I'm concerned that come winter I'll have to move some/most of these large loads back to the main service panel (grid) since there will be much less solar. All of the panels are on the roof (30 400watt panels). Anyway, I'll appreciate your thoughts on my winter concerns. Best regards
I’m in Virginia. So we don’t get the winters you guys do up north. We still have grid power available if we needed it. But at this point we have a large enough battery bank that’s it’s extremely rare. We have close to 90khw of battery now. I haven’t ever used grid to charge the batteries either way. If anything we would switch to grid power to enough sun was available again. We try to prep for cloudy or inclement weather in advance by doing our largest amount of cooking and other energy usage beforehand. I’m assuming you have an 18kpv as well? You could always leave some of those larger loads in the main panel and use some of the grid assist options.
They work great also. There’s a few reasons. #1 I like the space savings of one unit vs two. #2 idle consumption is half of what two XP’s would be. #3 the PV voltage limit is much higher on the 18kpv. So it makes it easier to run all my panels. But really the XP’s would do the job really well. That’s just why I’m using the 18kpv. Or at least that’s the highlights. There’s other reasons I could come up in sure if I pondered it more.
How much battery capacity do you have? How many days have you used a generator or the grid to charge the batteries? About where in the U.S. are you located?
I’m in Virginia. I have around 1700ah of batteries. So we had to supplement with grid a few days last winter. We still have the grid available as a backup as well as generator. We just don’t typically need to use them. The winter months typically have less usage for us because of the woodstove. So we are able to last multiple days with very little sun.
@@SD-it8nj I haven’t not personally tested the Solark. They are fantastic units though from what I’ve seen. I have tested the 18kpv quite extensively though. So that’s why I recommend that. As far as batteries it depends on when you needed to install them. But if I was designing my system again I would use the eg4 indoor Power Pro models. They are awesome. Built in fire suppression and they save space over a battery rack. signaturesolar.com/eg4-wallmount-indoor-battery-280ah-51-2v-indoor-heated-ul1973-ul9540a/?ref=mpmddlkx6M9tPo
I’m curious, did you actually have the power company turn you off and remove the power lines or are you still hooked to the grid but just not using it?
I might make a video on my solar input and usages. I still have grid available if I need it. But I have the beaker turned off. I did have to use it last winter during a week of rain we had. My wife has kept track of the days we’ve had to use grid. The meter fee is fairly low so it seemed like cheap insurance to keep us connected. Since we’ve added more to the battery bank we haven’t needed it though.

Curious what batteries you’re using that are showing individually on the 18kpv remote screen? I have lifepower4 units and they don’t show(they just work)
Same here too. Great question.
I’m using the outdoor EG4 power pro models. But you can also get the same info using the lifepower4 models. As long as you have the communication hub.
@@GavinStoneDIY the info is available in the hub but would be nice on the remote screen. Thanks
@@nathandeboer7974 it’s available on the remote screen as long as you have the hub. It just takes a firmware update on the batteries and hub. Check EG4’s latest firmware updates.
@@GavinStoneDIY unfortunately not on mine. Have latest firmware on everything
Do these have L1, L2 current transformers (or are they available) to use with on-grid so the 18Kpv will supply the house loads (almost all) but not back feed into the grid?
It has a zero export option. So the unit can supply power to the loads in your main panel without backfeeding to the grid.
@@GavinStoneDIY Fantastic!!!! I live in San Diego and that is the only way to safely power your house without issues with the local power company
@@benkanobe7500 yeah it’s designed with all types of options. Honestly it’s the smartest inverter I’ve used. 🙂
Great Video! You stated that the batteries are fully charged by 11am, what is your average SOC in the morning after overnight usage? Thank you.
In the spring I usually am around 75-80% SoC in the morning. So we don’t really have far to charge. It’s a slow climb after a day or two of rain though.
Cool. Would you say it's more quiet than a 6000 XP?
They have different tones. But they are similar noise level at full PV input. But considering the 18kpv only turns its fans on at 6kw or over, it’s definitely all around quieter yes. And if you were to add 2 XP’s to reach the same output power as the 18kpv then it’ll certainly be quieter.
@@GavinStoneDIY cool. Thanks. 👍
My 18 k EG4 inverter randomly sends 0.1 of current to the grid. Is there a fix for this?
It depends on how you have things set up. If you have it set to off grid mode it will not send any power back to the grid.
There is no need to fix that or micro monitor your system.
Gavin great video new to solar I use an average od 50kw a day with a well pump od 1hp
not looking to sell to grid however I would like to pull from grid automaticly when needed is this the unit for me
This, or 2-EG4 6000xp’s. If you aren’t needing to export to the grid then an off grid inverter like the 6000xp will likely work for you. Plus you have redundancy if one unit goes down you’d still have power.
Then again, a lot of people like to have everything in one box. And you really can’t go wrong with the 18kpv. It handles loads extremely well, and runs smoothly.
You mean 50 kWh per day! Power is kilowatts and energy is kilowatt hours.
Energy consumption is listed as kilowatt-hours. KWh Power is kilowatts. kW Otherwise you might be purchasing a water pump that produces 50 psi per day. 😂
What's your total battery capacity on the 18Kpv, since you mentioned being fully charged by around 11am? Just curious, since you have a lot of solar feeding it.
I have just over 100kwh’s of battery on the unit right now.
Wow, that’s a lot of juice!
@@kojakdurham yeah it’s been a slowing ramping up. I’ll be installing another 28kwh’s next week.
@@GavinStoneDIY Wow, nice
How many volts input on each of the 4 inputs?
I have around 500v input on input #1 and #2. Input #3 has 280v I believe. Those are my arrays. But if you’re asking what each input is capable of as far as voltage, it’s 600v max on each independent input.
Buddy I'm going to need all kinds of help to do this to my place you going to help me out
Email me questions as you have them. I’ll help where I can.
Hey great video on your 1st year anniversary. We are doing our first 6 months. A question for you .Where are your CTs located, by your meter or inside the inverter ?
I have mine set up inside the inverter. But typically you’d want them as close to the meter as possible.
Enjoy your videos! Thanks
I don't know where you are located, but you obviously have been through winter. I'm in the far north Idaho. How do you deal with low sun, clouds, snow? Generator, grid power?
How large is you battery rack...kWh?? You said that you are off grid or running as if off grid....and that you have wood heat.
I installed a "critical loads panel" and moved most of the largest loads (heatpumps, oven, dryer, etc.) to this panel. I guess that I'm concerned that come winter I'll have to move some/most of these large loads back to the main service panel (grid) since there will be much less solar. All of the panels are on the roof (30 400watt panels).
Anyway, I'll appreciate your thoughts on my winter concerns.
Best regards
I’m in Virginia. So we don’t get the winters you guys do up north. We still have grid power available if we needed it. But at this point we have a large enough battery bank that’s it’s extremely rare. We have close to 90khw of battery now. I haven’t ever used grid to charge the batteries either way. If anything we would switch to grid power to enough sun was available again. We try to prep for cloudy or inclement weather in advance by doing our largest amount of cooking and other energy usage beforehand.
I’m assuming you have an 18kpv as well? You could always leave some of those larger loads in the main panel and use some of the grid assist options.
What do you have for batteries?
I have a rack of 6 100 ah lifepowr4 batteries. 2 EG4 outdoor power pro batteries, and 2 DIY batteries. So a little over 1700 ah of 48v batteries
@@GavinStoneDIY hey, thanks brother,
I greatly appreciate you responding
why not 2 6000xp units for off grid?
They work great also. There’s a few reasons.
#1 I like the space savings of one unit vs two.
#2 idle consumption is half of what two XP’s would be.
#3 the PV voltage limit is much higher on the 18kpv. So it makes it easier to run all my panels.
But really the XP’s would do the job really well. That’s just why I’m using the 18kpv. Or at least that’s the highlights. There’s other reasons I could come up in sure if I pondered it more.
Do you need DC power optimizer on your 18Kpv and what’s the warranty on that battery?
I don’t use optimizers on my panels no. The warranty on the outdoor power pro batteries is 10 years. The same with the indoor models.
Good job
Thank you so much for quality content! Do you use string optimizers?
I don’t no. I would probably get a much higher yield if I did.
I wouldn't recommend that based on the fact that solar panels are so damn cheap these days.
How much battery capacity do you have? How many days have you used a generator or the grid to charge the batteries? About where in the U.S. are you located?
I’m in Virginia. I have around 1700ah of batteries. So we had to supplement with grid a few days last winter. We still have the grid available as a backup as well as generator. We just don’t typically need to use them. The winter months typically have less usage for us because of the woodstove. So we are able to last multiple days with very little sun.
How many solar panels do you have in total? And which manufacturer do you use?
I have 30 400watt bifacial sunwatt panels. And 6 450 watt sungold panels. Honestly I’m not too picky on panel manufacturers.
@@GavinStoneDIY good morning Gavin, which one do you recommend solark 15k or eg4 18k? How about battery and for whole house how many are safe? Thanks!
@@SD-it8nj I haven’t not personally tested the Solark. They are fantastic units though from what I’ve seen.
I have tested the 18kpv quite extensively though. So that’s why I recommend that. As far as batteries it depends on when you needed to install them. But if I was designing my system again I would use the eg4 indoor Power Pro models. They are awesome. Built in fire suppression and they save space over a battery rack.

@@GavinStoneDIY one quick question!
Do do really need EMP Hardening? Is it necessary to have and do you have it? Thanks
I’m curious, did you actually have the power company turn you off and remove the power lines or are you still hooked to the grid but just not using it?
I might make a video on my solar input and usages. I still have grid available if I need it. But I have the beaker turned off. I did have to use it last winter during a week of rain we had. My wife has kept track of the days we’ve had to use grid. The meter fee is fairly low so it seemed like cheap insurance to keep us connected. Since we’ve added more to the battery bank we haven’t needed it though.
How big is your battery system?
A little over 1700ah of batteries.
What part of the country do you live in
Virginia
Cool.
