Sol-Ark is flattered that Luxpower has imitated our revolutionary hybrid inverter design, but to suggest that a cheaper inverter is also a better inverter is inaccurate.
AC power is more important than DC power, and Sol-Ark provides 25% more daytime AC power critical for those heavy HVAC and well pumps. On the DC side, either way, the batteries get full on sunny days for well-designed systems. That's a long ways towards that price difference right out of the gate, before getting into MPPT comparison.
On that note, the MPPT are very different (~50% more for Sol-Ark). Getting to 18kW on the Luxpower is very difficult, requiring maxing out the MPPT which can trigger temperature design concerns on cold sunny days. Whereas it's easy to max out the Sol-Ark PV capacity due to its full sized MPPTs, even without expensive, premium solar modules. Which begs the question - what solar module configuration did Luxpower use to validate its 18kW claim? Can they show any long term endurance testing to verify that specification? Perhaps Will can do his own testing but the video only goes up to ~14kW.
Other technical issues - charge/discharge efficiencies are worse and the certifications don't match Sol-Ark - which has UL9540 2020 and UL1741SB options on the market today as required in California and most of the USA grid-tied market next year, and necessary for those utility battery incentives to improve the ROI.
Sol-Ark is proud to be the leader in the hybrid inverter. There are many imitations coming out daily, but only one, true original setting the standard. Also - Best-in-class is not just about engineering, innovation and R&D, but it is in the people and treatment of our customer-base. We're now moving into a 300,000 sq. ft. campus sized for 500 employees in our Texas headquarters.
@@Sol-Ark just learned last night about the increased AC output when solar available on the forum last night. Did not know that at all! I posted the spec after I found it.
And fortress power seems to be the first imitation. Not eg4.
Yes, we will see what listings they will have and how well the support is. I have no idea at this point.
I love the competition though! We need more options in the market, for sure. You guys are the leaders in this space 😁 I'm surprised they didn't imitate every specification. Doesn't seem that hard to do.
Love what you guys do and have a lot of happy viewers running your units! I don't think I have a single forum member to have complained about your support, either. It will be interesting to see how these other companies will compare.
Do you have any plans to lower prices in the future? I assume you guys sell predominantly to installers, but I could be wrong. I feel like the luxpowers and others coming out will be more popular for direct to consumer. I can't wait to see people compete with the 18K in the next year. Perhaps voltronic will come out with something even better.
By the way, I sell all of my sol arks through current connected, and they are fantastic! I am glad you work with them.
@@Sol-Ark and yes I need some more strings. They are saying it can go up to 600VDC on the input.
I have a lot of viewers that want a sol ark but simply can't afford it and instead buy the lv6548 clones. For $2,999, it's not bad. Not code compliant in some areas but they are cheap and get the job done.
Could sol ark make a off-grid specific unit to compete with the lv6548 clones? That would be so cool!! The more competition the better
@@pvbatts there are some variation between all of the models but I'm not sure yet to what extent. They are saying they can have the VOC up to 600 on the EG4 version. I know there are some differences with the fortress power version as well. I put 500 in the video because that's what they recommend is the working voltage. Some of the official documents are not consistent though so let's see what they have when they are listed.
@@Sol-Ark what does sol ark think about the fortress power version of this unit? It's been out for a while now.
THIS is what I have been waiting for. Please, oh please, let this thing be reliable.
My thought exactly. I bought a Sol Ark and I still would even if this had been out. It’s been rock solid. Specs mean noting if the unit dies or glitching constantly.😊😊
@@NeverTakeNoShortcuts been running a 8kw deye, 15kw solark and this 12kw luxpower. and hands down luxpower is the best value. and the solark has more issues than the others, its very sensitive to unbalanced loads.
@@alexandermoore6027 What size loads are running on the Solark? My maximum load is is 7kw, but I still worry about the load balance on the 15kw.
Had my solark 15k for 8 months now and it's already got like 13 MWH through it.
@@alexandermoore6027 I have had my Sol Ark for over a year and never once had an unbalanced load issue, and I have had some very heavy loads on it. Of course I designed my system based on the published specification and best wiring practices and use the most recent firmware. It's a non-issue for me.
That thing looks really nice and well built. And it's the first one on the channel where when you show what you're doing on the display, it actually just makes immediate sense to me. Good signs.
can't help but love your content and break downs, that help with understanding what the upside and down sides to all units you show. Really helps when it comes to is this unit for me and my use. And made me realize that what I needed and didn't need depending on application use. Keep the hits coming... love your channel. So very very helpful!!!
Thank you for your kind words! I'm glad to hear that my videos have been helpful in understanding different units and their applications. The Segway Portable PowerStation Cube Series could be a great addition to your outdoor gear. Its massive capacity, fast recharging, and waterproof technology make it a reliable choice for camping and home backup power. Keep exploring and enjoying your outdoor adventures!
I ordered mine as soon as Signature Solar had it available to order. Excited to try it!
Will, I am blown away at your technological capabilities as well as your impeccable communication ability. I'm in Pahrump which is about an hour away from you in Sin City. I'm off grid here with (2) EG4 6500's with (28) 445 watt Eversolar panels all acquired via Signature Solar. Should be up and running in a few days if all is good w/o needing firmware updates. Much of the installation procedures are followed by your incredible input and I thank you very much for what you do for us, your followers.
A friend of mine who's a heavy hauler he's been Heavy Hauling for many years moved to Pahrump from San Diego. Paul is his name now I can't remember his last name dang it. Anyway enjoy your solar. Sure is amazing stuff I wish I was a little bit better at doing it slowly but surely I guess. I can't believe how good most of these DYI peeps are doing😊
@@VinceBadovinatz88 Small world indeed, eh? I drove 18 wheelers for about 10 years 48 states & Canada back in the mid 70's thru mid 80's. Retired now and been prepping for years for what's to come. Stay safe and hope you can become totally self sustaining.
@@leonardharview4577 yes it is ,and thank you very much😊
Paul Goldstein Heavy Haul
I've been testing this 18k unit for over a week now it's working great And soon I will be able to provide tech support for the 18k units we sell And we will answer the phone. Great video keep up the good work.
Do you sell complete packages
@@jeffsowers1290 yes
That is the cleanest and easily accessible cabinet I've seen so far. Must been a dream to work on.
so easy
Remember adding a dorm fridge to a camper?
lol 😂 love this content!
This looks like something many people are waiting for, lets see how it goes "in the wild" for a few months, if it proves reliable it'll be a big seller !!! I'm using SMA Sunny Island/Boy which has been flawless for the last 5 years, hopefully they have a good recipe here !!!
Thx Will, I finally found the best way to setup my ultimate solar system. The EG4 18K-PV plus 4 Discover AES 42-48-6650 (each battery has 6,650 amp hour) no system can beat this type of combo.
That battery seems expensive per kWh, no? Why do you call it part of your ultimate system?
@@jamesreichert Absolutely! You got that right. Being the best should come with a price though.
So I've been doing a lot of research and I found this video to be very informative. I really like all the features on this system, it's got evening I'm looking for and then some. And for the $$ I haven't seen anything else that beats it. I personally don't care about customer support. I've been in IT for +25y & elevator mech for 11y before that and I don't ever call tech support.
Thank you for all your work.
Bought your hardcopy book. Love the videos
Well that looks very promising, enough to look after our house and I can start with Net 0 and add batteries in future for backup, much much better than the micro inverters option our solar providers are using (we are less than a kilometre from the ocean and here in Vancouver BC with all that salt moisture etc not friendly to micro inverters), great review and again a great product, UL/CSA it is a no brainier, totally awesome! Thanks Will, you bring such a great resource to alternate energy!!! Keep it up!
I just bought two batteries and the 18k. I’m praying I can use your videos to get my system up and running. My plan is to use a generator to recharge daily, while I’m trying to decide if I need to invest in solar panels. I’m in west central Illinois right on the Mississippi River at lock and dam 19.
Good review. This unit is going to be a big hit I think. And you’re right, that thing is super quiet.
Excellent video. Love your very thorough discussion. Keep up the good work.
Will, they need to put you on retainer, as you're doing the field testing work for them. Pointing out the problems with their earlier products and the improvements that will make them better and easier to use. I save your videos so when I get time I'll use them as a buying and setup guide for the system I need. Thank you.
As always good video Will. You are one of the lucky few who have been able to get their hands on this thing! I’ve heard a lot of complaints about EG4 inverter software issues. Seems like a lot of people have been burned by them before. I love their 48v lithium V2 batteries though. Hopefully they have solved the software issues.
This inverter looks very encouraging. Can't wait to see your follow up videos after a few weeks of use. For your next video, can you also look into neutral ground bonding for this device to make sure it's configured correctly for various connection use cases (offgrid, on-grid/grid tied etc).
Thanks so much for this review. I’ve been waiting for someone to review this unit and you’re the man I trust.
In Texas it does not currently pay to grid tie as those electric plans are much more expensive. But this seems viable for back up power and select off grid power to split system hvac and EV. Ready to get going. Thanks for your thorough instructions.
Im in Texas as well looking forward to using the grid as backup and solar as the primary. Not looking to backfeed at all
Will, when you measure sound level it's usually measured at a specific distance (like 3 feet). Great video!
Awesome , finally something that just works. This looks ideal for my shop and it should run my AC, lighting tools and possibly my air compressor as well.
This is the power of competition!
Will, we're building an off-grid cabin. It sounds like this will more than suit our needs!!! 🤞👍
Hey Will, great informative video as always! The only comment here is in minute 8:25 where you explain the CT positions. The manual actually says the arrows should be pointing toward the inverter.
I was about to ask about this as well. The way Will has it makes more sense to me but everything in the manual shows it facing towards the inverter
Amazing how far these units have advanced in the last 5 years. Unreal
I took the Upgrade option. Traded in 2x 6000EX for an 18Kpv. I'm glad I did. The new inverter does every thing. I especially like the sealed electronics and imbalance issues are way better.
Setting up the 18K was easy. Getting the batteries set up to work was not. I had issues setting this up with my EG4 batteries. Hunting for Battery Firmware for a mixed generation to communicate with each other and upgrading was a nightmare.
Inverter: 18Kpv
Battery: LL-s, LL-V1, LifePower4
Most homes have a 200A panel - the 18K will be so easy to install. It's one less box on the wall. Remove the 200A from the Panel - attach 18K output - back to panel. Done Very Simple. The LV6548 - are so much harder to wire on 240V side. You almost always need a sub panel.
I always enjoying your informative video’s. Thank You
I am shocked! I expected this unit to have the same issues as the eg4 8kexp-240.
So glad you were willing to give this a try after you had so many issues with the other eg4.
Thank you!
Thank you it's amazing the technology that is constantly coming out this is more information to consider when setting up an off grid system thank you for sharing this six stars
My next house is gonna have this setup. Thanks Will
Yep, this is the video I have been waiting for.
this is one of those videos that in the first minute I'm like this is just too good. thanks Will!
Will, another great video!!! In future, can you do an AC coupled system with this and review their monitoring?
sounds like a great upgrade for those of us who originally built string inverter systems before there were any offgrid/hybrid options for grid connected systems. Any panel adds at this point would kill my NEM 1 agreement with utilities. But in the meantime, I could add this, add battery, and when the time is right (after NEM agreement expires) I can add more panels, and handle fully electric home needs plus EV. Thanks.
This one is the best fit so far to what I’d like to do.
Wow, solar has evolved. My LV6548’s are doing their job(thanks to you) and don’t really have complaints but when I move, these may be sold or left behind. I may be looking at my next inverter. Great job on your review as always.
Just ordered a 16 k array with eg4 6500 ex times 2 from signature solar. I credit Will for the knowledge and training to take this project on.
Will, do a segment on insurance/ power company contracts etc. My system is gonna be off grid and uninsured.
This looks like the solution I want for what I want to do. Nice review, Will!
Super thanks for the video particularly the programing demo the manual is good but it's so much better watching some one work the interface. I am now installing my 18K but being a inverter newbie it's taking some time to get to know this piece of hardware / software and more info is good info.
I love the content. It gives us hope we can be in charge of our future concerning power. But I find the actual strength and the overtime reliability is a constant money pit.
Great review as always Will. Thank you.
What a great video. What a great product I hope the long-term is great. There's no way I can afford it right now but if it's a great product long-term I want to get one. What a great idle consumption.
I have to watch the video again I can't quite remember or understand how much PV input you need to make it run. It seemed like that was rather High. That could be one downfall for people that don't have a million panels. I'll have to recheck it or if somebody has time they can let me know in a comment. Very impressive . N once again i really love your video presentations.😊😊
Waw, really awesome and very informative. Great video, as usual!
Hey Mr. Will, Love your videos, super helpful. I bought the 18K and thought I would let you know the issue I was having. I have a Generac generator hooked up to the inverter and turns out that the dry contacts will not change state when the power shuts off without a battery bank in the mix. I don't have my batteries installed yet so my inverter will not fire up my generator during a power loss. Signature solar tried and didn't get it done so I called EG4 and they tried with no success. The tech said he was going to get with R & D to put that in the next firmware. They were supposed to get back to me and never did. I just bought all my solar cells and Overkill bms units, so I will probably get the battery bank in before they fix it. Just FYI.
They must be proud of that 18k PV to put it on the front, lol.. that grid supplement is a very cool feature. Have not seen such a feature before.
I would love a follow-up video on this after it has been used for a while. Some follow-up videos on other products that have been good for you would be cool too.
Thanks for reviewing this one Will i seen it sold out quite quickly already
New load just released
Really hope to see self consumption working on this inverter. I can’t sell to grid in my area but would like to power loads in main panel if critical loads are met and there is excess PV or battery.
Wish the EG4 6500's I have had an interface like this one. Looks like alien writing from the movie predator. Glad they got to the year 2023 with this model interface.
Finally a all in one that is not too expensive I want it take my money
Will I been waiting for u to get one too see how they are there nice..... Keep it up brother
As a retiring educator, I am most impressed with your work, and your abilities. That said, if we have a unique scenario, we are thinking about doing in our lives, is there a way to communicate with you about that? Fee set up? Friendly help? I’m sure you’re quite busy. Anyway, thank you for your time.
This looks awesome. I’ll probably get one if people don’t have issues.
I’d like to see head to head comparisons between high & low frequency inverters. Your otherwise excellent videos seem focused on your specific needs by testing predominantly steady state loads, but real world whole house backup has to deal with peak inductive loads that trip up high frequency inverters.
Hi Will, thanks for all tbe great videos.
In the comparison to the Sol Ark at the end, it's worth noting that the Sol Ark 15K has a 15kW inverter, but the 18K PV only has a 12kW inverter.
Per kW, the Sol Ark is still slightly more expensive, but not as much as this comparison would suggest.
My FL utility raised its kWh rates to $0.11 for the 1st 1000 kWh then $0.13 over 1000 kWh each month for residential. Raised about 1 penny. You guys are tough out west paying those high rates.
So so happy to see this review! So dope!!!
Ya He's easy@ 😂eyeS
Sound should be measured in 1 meter distance. Nice video as always 👍 You can probably set it to "Zero export to CT" and will automatically get your meter to stay at zero.
Thanks for the video, Will looks like a very nice unit, time will tell, might have gone with one/two of these if they had them out a year ago but as with anything in solar new products are coming out every month and there will always be something new around the corner. We are currently running the EG4-6500s as off grid set up and after doing the firmware update for the error 61, they have been working faultless and performing very well. However, with that being said the time to buy is now, we are seeing and will see more issues with supply chains, suppliers' weather due to political, restricted access, or conflicts. If things settle down in the future would be nice to upgrade to something like this unit or even a Solark however the EG4s 6500s are very cost effective to the point we have a redundant system. That would be very hard to do with something like a Solark unless you have ample income. Yes, I know you get what you pay for but it's better than not having anything at all.
Stay Safe & Good Luck
Another budget lifepo4 showdown please. And thank you. Low temp would be nice, there seems to be more on the market lately
Sure sounds like a nice unit especially compared to the smaller earlier Eg4s or Growatt. I wonder if they are planning on bringing out a smaller unit? Not everyone needs 18k input or 12k out. A smaller efficient unit like this would be great.
In your next video about this can you talk about what you can do if you have more than the 12kpv to charge? For instance if you have 2 server rack tower banks and 30kpv and want to charge faster than 12k.
A side question: is there a limit on how much you can sell to the power company where you live? Do other areas have limits?
Always enjoyed your videos and style 👍🏼
THANK YOU SOOOO MUCH, WILL❣️❣️❣️
You da man❗️
love your channel, I hope you do enphase IQ8 battery system someday, the load leveling looks amazing by leveling production
If its California compliant, you know it's good. This is the unit a lot of us have been waiting for. I never liked the hybrid units a few years ago, because the cheap ones were sketchy and the good ones were crazy expensive and ran at low PV voc. Having such a high PV voltage and several mppt's is so useful, and with the panels on the market, you can size it cheaply and easily.
P.s. they have a lot of "refurbished" units a year later. For around the same price as a 12kpv that's brand new.
Thank you for the video Will!
I have learned so much from you and have built my own system, choosing the parts carefully based on the information I learned. I love your fair and analytical approach testing and sharing information. Don't let others affect you negatively, I think in those cases they might be trying to rise to your level by posing a false strength. The sad part is they could never reach it and perhaps that fear manifests as negativity 💪 Thank you again!
As always, very thorough and well explained. Thank you Will.
Question? I have designed and built my system based on the knowledge you have shared, thank you. I had 3 Eg4 v2 batteries in a rack and I bought a full rack of 6 and they are the newest with the dip switches on the front. My big question is can I just connect the tower of 3 to my busbar next to my rack of 6 and connect the BMS communications or do I need to balance the racks?
Great content Will. I'm amazed on how hybrid inverters have evolved in the last 12 months. Can this unit operate as a 240v single phase system if you love outside United States? Thanks again.🙂
Thank you for a longer video
Super video Will I glad you’re the first to feature this unit I’ve been looking forward to this unit since I received a notification from Signature Solar
First all not sure it’s for me due to the rather high cost I do love many of the features
But I think I’m still going the 6500EX due to the fact that they will give me 13K inverter power and I’m only losing 2000 watts of solar with the 6500s
What did catch my eye was the Dongle
Internet connection plus those CTs that you pointed too can you please cover this in more detail and can it be used on the 6500s
Once again thank you
Hi Will, love your videos.
Have you considered making a video on how to run an evaporative cooler on DC. I live in West Texas and evaporative coolers are still being used. Also, could this be economical to the average person living off grid.
This is perfect for new home builds too yeah? Super pumped to see this. Thanks for sharing!
Been waiting on this one
Software HUI is remarkably similar to the Sol-Ark. As you mentioned, the gripe I have about the Sol-Ark 15k is the amount of room in the wiring area. Also, to use the SA as the grid connect a 200A service panel needs a minimum of 2/0 copper, but SA's punchouts are 1.5". They should have been 2" due to the NEC conduit filling percentage rules. Forget about trying to use 4/0 aluminum.
I will echo the room concern aluminum wiring eats it up instantly.
I have a harbor freight hydraulic punch and I'm not afraid to use it.
@@jkj2r80fojf23 Yeah. I use expansion couplers to join up to 2" conduit. Keeps an inspector happy.
You are spot on correct about that but I have been able to get the 15K installed with 2/0 DLO cable on the output and 2/0 THHN on the input. IF you want to save $$$ by using the 4/0 Aluminum it might be beneficial to mount a distribution block in a large wire duct (gutter) under the inverter and just use a short run of 2/0 THHN up to the inverter.
@@MrWatlow Good point. After I did my first one, it occured to me I could run the aluminum 4/0 to a Polaris and go 2/0 copper from there. Too late, but at least that and your thought are possibilities.
Thx Will, I was not sure whether to get a Solark 15K or a Schneider XW Pro. Now I know what to get
HOLY MOLEY! wow...
This could be a game changer!
Its too bad they are so much more expensive than a pair of 6548's
Better options, better wiring pathways, but less output from solar than the pair of 6548's
I really wish they had kept or improved upon the 6548's output.
Thanks for the review Will.
I'm excited to see what the Wi-Fi and Web service looks like
Will, I reviewed this video several times to see if you had mentioned the difference in power loss between Sol-Ark and the EG4 regarding efficiency ? I know that Sol-Ark has a company standard on their inverters of 97% efficiency.
Excellent Review!!!
Thank you!
Think this will push me over the edge to build my first system. I was worried about code compliance and simplicity of design of alot of older units , I think this paired with eg4 server rack and 12kw Canadian bifacials will be the ticket!
What state are you in? If in California the eg4 server racks are technically not allowed because they are not on the cec approved battery list (yet)
@@bschmitty77 thanks for pointing that out. Do you have any information on that being subject to change.
@John Dawkins yeah, signature solar said they submitted all the released info and testing for approval. But I'm sure california will take their time and I know the "standards" for those tests being qualified are stupid strict.
@@bschmitty77 thanks. I’m glad to hear that at least the process has started. Unfortunately, we do take forever in California. I’ll hope for good news. If you hear any updates, please reply again. Thanks!
@@bschmitty77 I’ve been in contact w SDGE and Signature Solar the last week trying to get this and the batteries on the CEC list. We are still waiting on SS to provide the testing for the inverter to the contact I have at SDGE and then they will submit. Frustrating, and maybe a bit of a red flag, that SS isn’t eager to provide that. That opens up a bunch of business as soon as these are CEC approved.
I hope the smaller units get upgraded with new fans/heat management so they run quiet enough for to have in your workspace
Thanks Neighbor!!!
A lot of great info.
Step aside Sol-Ark! Building a net-zero 4plex in SoCal this summer and will be combining this with their 30kwh battery rack and a 20kw solar array.
I would love to see an added page to your 48v blueprint page with this 18Kpv . Don't ask me why but I love to look at all the systems you built
Hi Will! Your favorite forum member here! Truth hurts, doesn’t it!
What?
I love your videos..but just noticed your instructions on the CT clamps seems wrong after looking at the manual..shows the arrows pointing to the inverter..u said to point toward the meter / grid
You hit the nail on the head with the support issues with signature solar. Sadly, their support has gone from really good to horrible in the past year. The reality is none of this stuff is plug-and-play or perfect and you have issues here and there and will need support. I have been waiting a literally a month for a case on a 6500 from them. It is a sad situation because they are the cheapest around but their support is god awful today.
Dennis, if you are comfortable letting me know what your email is I will look into this for you tomorrow morning.
Solark has the same problem. They used to be great now they're beyond awful. To the point where the Solark support guy gas lights you, ignores what you're telling and showing him. I guess Idiocracy is a sign of the times.
I actually drove to signature solar while on business in Texas and visited SS in person. I was treated very professionally, and several hours of questions were adequately responded to. They were also very honest and upfront about manual issues with the 8k and so on.
I suspect the "support" issue rises if you find a firmware issue, or need something an actual engineer building the stuff has to address. I was not under the impression they built these here, and I imagine part of that $3k difference (emp protection?) Is access to the people who construct and engineer the systems if needed.
Very high technical inverter wow
Thank you for such an informative video Will
Why the external T class fuses to the tower rack bank of batteries
and external natural overload breaker/busbar? Is there not room to locate them in the unit?
Other than that, I like the connectivity, LCD and it's features for energy distribution (PV panels, grid, battery storage and off peak demand) I also like the isolation side switch on the side.

I am currently setting up an EG4 18KPV and just wanted to report my experience so far with EG4 support, I have made 2 calls and have received great support with very short wait times so far, I just wanted to put that out there if anything changes I will post it up. Depending on how this goes I may be buying a second to be able to use Solar and Battery as my primary source (right now I am setting it up as a critical load panel setup only) with grid for back up under extreme load scenario's (it's in a very large house) but we will see, this is my first solar setup (I do have prior residential electrician experience so can't really comment on the DIY end, it could be a bit daunting I suppose but for me it has been pretty simple), so still experimenting.
Question on inputs. My understanding is you can use micro inverters with the sol-ark and run 240v into the generator input. Can the new EG4 do that? Second is that the optimum way to maximize the solar panels?
