Will, Please ask Signature Solar to provide more programing options for the time of use and charge settings. I've tried time and time again since the 18K first came out. I talked with tech just last week and I'm afraid my efforts have fallen on deaf ears yet again. We want to, but can't buy it until they make it more flexible like the Solar Ark 15K settings are. Thanks, Tony

Is this a low frequency inverter ?

i just built the 48v complete off grid with bifacials just like on your website. with the 6500ex's getting 8k watts. been running for a week now. no issues. THANK YOU WILL

Great videos Will! I’m really liking the EG4 so far over some of the other companies with similar product. Great value.

Amazing as usual. Keep up the great work 👍🏻

Thankyou for the refreshers on the last few vids

I know you’re having a good time with this because you work so hard to find issues with products!

Thank you Will. I was waiting on this video. Now that I am sure of this product, I will purchase. Just got to drive about 2 hrs to Signature Solar. Have a blessed week.

I really appreciate the long-term reviews. I am imagining a few years down the road when semi-solid state and solid state become the norm and prices start to drop. Exciting times.

Your straightforward honest and thorough reviews helped me make a confident decision regarding the equipment I chose for my full time transit bus RV conversion.

Not boring at all. I like seeing when you get excited about how good a product is. There's so much garbage out there, it's nice to see you excited about the good stuff!

Will, I like your reviews because you give the Pros & Cons without bias. Recommend possibly a db meter when you say, "loud".

All I can say is WOW! I'm in awe. Nice set up

These are really nice, i'm glad you are continuing to have good luck with it. Did you see that the brought down the price of the Sol-Ark 15k (8,300 => 7,000). I think it was directly because of this product. If you buy the EG4 or the Sol-Ark you still need to thank EG4 for driving the price point down

One thing you aren’t is ever boring, Will! 🖖

Excellent video, NOT boring!

SOLD! lol I've been watching the review videos of this unit with great interest. As soon as I have the cash, I'm buying one. Thanks Will!

Oh. You have done this surge test. Thank you for this. I don't know if you can get the Growatt 12kw one or not. But this is great.

Will, We just got our kit from Signature Solar a couple weeks ago. Still looking for an electrician to connect it all. The rack I have is the newer 2023 rack. It has a door, floor, is all welded and came shipped as one unit. The busbar is different (all flush, thicker, and has lugs on both ends so you do not need to flip it around). There are two holes in the top for wires and four in the bottom. The casters are super heavy duty. Sounds like they addressed most of your complaints.

None of your videos are boring will we learn a lot from them

We need a shop tour! Let's see the cars and the lift!

Impressive content, I love your videos.❤

That's awesome to hear! I wanted that one (18Kpv inverter) to just work. Looks nice as well! Thanks for the updates..

Thank you for your time

got my 18K after Signature Solar did their rebate for folks who had bought the 6500ex's. Set it up and it worked like a charm for a couple months. Then all of a sudden my power shut off and it said there was a battery fault. Apparently there had been 'battery voltage high' alarms for a month or so, but the EG4 Monitor app doesn't actually alert you of any of these, it just catalogs them so if you don't look you won't know. Checked all the voltages at the battery terminals as well as at the unit and all were nominal (batteries measured 52 or 53, inverter measured 55V). Signature Solar tech support verified this on their end and said everything was fine. Powered everything on again and even though it is functioning normally it is still sending these alarm codes. SS said it was likely a software issue. Fat lot of good THAT does me. System is set up and working as it should but the software will shut my system down?

Signature Solar just dropped a load test video yesterday that IMO shows it did better than advertised and cleared up some questions I had there. I am going to buy either the Sol Ark or this one in the next few days. The one question I don't see answered anywhere is whether you can hook up a gas generator to charge batteries with the EG4 and as I want to be off grid and have the ability to do that in winter when it is dark and rainy for days as happens in Texas, having this option is huge for us. We are outside of city and on electric co op so have zero interest in sell back, it doesn't pay. The tax write off and my location does make paying off whole house doable in under 10 years. Would LOVE to know the answer to this one questions. BTW, I get Signature has at times had longer wait times but its the growing pains of growing a business, I am ok with it. I have been very happy working with them. Being understanding and supporting these types of businesses is what leads to better options for this community.

Wow all I can say you can power a whole village with all them battery 🔋. Great job

Great to see new companies entering the space. Batteries will only get better and cheaper the next couple of years.

So I purchased the SolArk 15k well in advance of when I needed it. It’s still in the box on the original pallet. 2 months after my purchase this came out. My question is, should I ditch the SolArk and buy this and save myself half the cost? I can probably sell the SolArk to a local company for what I paid for it. What is the real sacrifice? I’m having a hard time finding one. My system will have 11Kw of micro inverter panels, 5kw of standard panels, EG4 or similar battery and a 22kw Generic. I’m “on grid” and would power arbitrage if possible. Ok someone talk me out of this?!?

He aint going to do it because the Sol-Ark is better Inverter, it has true customer support and Zero bugs. He does not make any money from Sol-Ark sales so why would any KZreadr promote a product that offers them no financial gain over one that does. I Sell and Install both the Sol-Ark and the Fortress Envy witch is the same thing as EG4 12K/18Kpv. The Envy has lots of small software issues that make it a PITA. I put in a Sol-Ark and it just works, no customer calls. I put in the Envy and it's constant issues. Those people at Fortress offer good service but they cannot fix the problems when it's the software.

Thank you Will!! Curious what inverter/charger/charge controller you'd recommend for an RV that doesn't grid-tie.

Love your videos. Can you do a video on retrofitting a 18KPV onto an existing grid tie system (7.4kw enphase microinverters IQ7+). I ask this because CA is about to push out new electricity rates based on income which will essentially make my net metering benefits obsolete. This rate change makes me want to disconnect from the grid completely. Im curious of the best way to do this with my existing grid-tied micro inverters. I'm thinking of adding the 18kPV and about 30-60 KW of server rack batteries. Does the 18kPV allow one to set up a micro-grid and allow the enphase microinverters to continue to work without a formal grid? Of course I would use a 9KW inverter generator as back up to charge batteries if they ever go below 15% SOC. We do have some cloudy/rainy days here in LA. What do you think? Interested in making the video? I am familiar with off grid systems. Built a 120V, 7 KW solar, 15 KW storage for a cabin we have in Big Sur. Works great up there but really want to build something here that is AC linked with my existing solar. Phase 2 would be add V2H tech when I eventually buy an EV.

Will you videos are so respected when you say a boring video 😅 it means you find no problems with this product... thank you man

2 videos in one day?? Lets GO!!

Can you do a video on your 18k install explaining how you did it and what additional components you used?

Keep the 18kpv updates/Stress tests coming, gonna bite the bullet soon

Very nice system. Can you do step by step installation and wifi setting for this 18k

Will! I love your videos and book. I built a large solar generator based off it. Similar to your dolly solar generator. I am trying to figure out if it makes sense to buy a medium sized solar generator or DIY one. Something similar to the eco flow delta or a river 2max. What are your thoughts? I want something i can toss in a vehicle (easily) and go or have at a picnic with the family

I'm sure they are boring to u and maybe some of us but I enjoy seeing them systems work. Not sure if the videos make any money. Just my 2cents maybe a short would be cool

Hi Will. I have one of these inverters and couldn’t be any happier with it so far! Let me ask though for those of us operating off grid or with a zero export constraint, how can we configure the system to turn on additional loads to avoid missing out on solar productivity once the batteries are fully charged? You know loads like bitcoin mining or water heating come to mind.

Just received our 18kpv system with 6 life4 batteries. Looking forward to getting it set up. I hope my power company approves everything faster then I can put it together or im going off grid😁

You can trigger a gen at a given SOC and you can set times to charge from the grid, but I don’t see how to trigger a grid charge based on battery SOC.

The larger 12KW probably runs cooler with smaller systems wonder if it better to go the larger inverter even if you only plan on 6000-8000 watts. If you mount these inside have to cool them running near max capacity generating lot of heat have to cool.

Hi Will, great video. I wonder if you have plans to test MPP Solar LVX6048WP inverter. The LVX6048WP look great in paper and good price. But not sure if is to good to be true.

Would you show the step by step connecting of the max amount of solar on each PV connections ?

Can you do a video on communication between batteries and inverters? What are the protocols and what is the benefit? You keep mentioning it but I don't understand why it's necessary

Hi Will, there are a few details about your test setup that are important to the evaluation of a hybrid inverter. You did good on the performance of the SW interface. there are alot of installations that will want to connect in existing AC coupling, be able to sell to the grid and AC couple when the grid is down. This requires a transfer switch in the EG4 inverter that can manage the isolation. It is not clear how you are testing this mode. Related is the configuration is that many solar systems would be most economically modified by just adding in the EG4 inverter which most generally may also require not having the EG4 inverter near the service entrance. This requires the EG4 be able to control a remote contactor at the meter. It sounds like your shop and house loads are distributed suggesting a this test setup. How does the EG4 do in managing the grid tie when the meter is remote? thank you

The two off grid installs I have had generator starting issues as well as the same flickering light issues. Customer spending $30K on equipment I just tell them spend an extra $1K and get SolArk.

How about reviewing the SolarArk EMP hardened 15Kwh Inverter and ESP batteries?

I would love to get one of theses, but i have iq7a micro-inverters and im not sure how I would get that to work with battery backup in the event of long power failure. Is there anyway to AC couple grid tie and have the panels charge batteries?

Do you still need a genverter if you want to also use a generator as a redundant backup to charge the batteries?

Would it be better to run 4x of the 3k units instead of the 18k (actually 12k) unit? 4x3k would be half the price and yes, they could fail, but if one fails, you still have 9kw output instead of zero. Maybe buy 5 and have a spare?
