I personally empathize with SS… I own two businesses and in my experience the public has a short fuse these days. They also refuse to do their own research. And with this industry being fairly new to the general consumer many of the complaints and questions are just due to the lack of...

My monster system is done on the DC side… gotta upgrade my service to 200 amps and put in the transfer switch with a friend that’s a great electrician. System components detail: 2 x 15k Sol-Ark inverters, 3 EG4 Power Pro batteries, and a rack of EG4 LL batteries as backup. PV is 12 x 400 watt...

Great test... thanks for putting in the time to do that for all of us solar junkies. I love my two 15ks... runs my whole house without any issues. I'm working on setting up a long term, real life, day to day test to compare the 15k to the 18kpv. Working on getting the materials to tweak my...

Have you tried to use the Sol-Ark system sizing tool or the solar panel calculator? I found them very useful. FYI we live in southeastern Louisiana and have the following system that powers our whole house. Link to system tool: https://www.sol-ark.com/calculator/ Link to panel sizing tool...

Like I said in my post it seems to be hit or miss from what i've seen and talked to other Ecoflow users. Mainly the SHP that was my issue. That and the poor tech support that kept making me start from square one every time I called them. Hard to connect to the higher level of tech support...

I’m definitely going to look into the laws posted I’m a notary public and my sister is an attorney and I will ask her advice on the subject… FYI I’m going off grid living in New Orleans

That makes sense… only one of the batteries started acting up the other two were fine UPDATE — UPDATE. — UPDATE Quick update: thanks to Markus_EG4 I think we’ve solved the issue and I have a plan of action. Two issues came into play 1. With Sol-Ark inverters connected to EG4 Power...

What percentage discount did you get for military? The current price to the general public on Signature Solar's website is $5199 each. Was your pricing including tax and shipping if it applies? I’m trying to understand your numbers. Prices offered to the general public without any discount...

I can relate to that need. That's why I went with 2 Sol-Ark 15k's in parallel... I have 3 EG4 Power Pro batteries as my main battery bank for daily use with a rack of LL V2's for reserve power if needed. Appreciate you sharing. Fun stuff.

I get it everyone wants things to work perfect all the time.... but reality is every mechanical device can fail and Murphy's law says it probably will. How we handle things when they do fail is a separate issue. As long as a company is doing what they can to solve issues and they are listening...

I just got an early Christmas present... can't tell you how happy I am to hear about the coms. And now I feel even more justified in the extra expense for the LL V2's. I'm a hi tech junky and it was only logical to go with the V2's when I new I had eyes on the new power pro

Just ground the rack and you should be fine

Sig Solar will ship flat rate to a residence $150 and where I live they haven’t charged me tax. Ordered from sovereign because I wanted to go with the Sol-Ark 15k over the 18Kpv after doing my research. I was just showing that it’s not that much difference in price if you’re trying to decide

Thanks I appreciate the effort. I'm sure I'm not the only one waiting for that firmware update

It’s a rust spot but I like your story better🤣

The sleeper has not awakened 🤣

I think its a case of a company growing faster than they are ready for... I think that the delta pro is a good product but they are trying to add too many new products without truly working out the bugs. Quality control could be the true problem. Several people may get a SHP with no issues and...

Ran across this article and thought some of you might find it interesting. With much of the discussion here being about generating your own power... how would you like to have your own micro nuclear reactor...

Works with the EG4 Power Pro batteries. I have two 15ks and 3 power pro batteries and they work great.

thanks 2.5 is what I get using the calculator and the actual battery numbers and for my rack of 6 EG4 LL V2 batteries (backup or reserve power to my wall batteries) I get 1.9 m ohms using the calculator and the actual numbers from the QC sheet.

That would be nice but I’ll believe it when I see it

Like the others have said the Sol-Ark is designed to handle that situation. As a matter of fact its so smart it can tell when the power from the company is fluctuating and will disconnect form the grid temporarily until it senses the power is stable and will reconnect. I have two 15k's and they...

I'm interested as well.... all in due time. I'm waiting on some materials to do the rebuild the right way. I also have to do some more testing on the full compliment of batteries with my current setup which is working flawlessly so far. I'm just in my first full deep cycle with the rack of EG4...

The internal bus bars are rated at 600A… if you check the manual they suggest using the internal bus bars with systems with up to 5 batteries (3 15Ks in parallel with 5) and then use external bus bar with systems requiring more than 5 batteries.

Just want to give thanks and praise to Sol-Ark tech support. I was having issues with a current overload fault and parallel fault with my two 15Ks. Nothing made sense and I was worried it was something I did in the settings. After 1 hour and 48 minutes of the process if elimination with tech...

I just wanted to be crystal clear thanks brother

Will do… I’ll let you know if there is any issues. I should be finalizing my AC side tomorrow. Electrician should be here tomorrow at 3PM. Can’t wait to run test on my new monster

Battery type is 00... and yes as you can see in the pic i have the EG4 conduit boxes on top of each battery and then I ran connections to a main bus bar in the wiring trough below the two sol-arks, and then connected the main battery bus bar to the two sol-arks. I've been tracking deep cycle...

I have 2 Sol-Ark 15ks in parallel connected to 3 Power Pro batteries and I finally got the AC side done yesterday. My system was running fine on battery only from 10PM last night until around 11:30 AM to day… then the BMS from the batteries started sending incorrect voltage and SOC information...

Thanks I hope those settings work for my LL batteries. Since the last time I communicated with you on this topic my situation has progressed. I now have my two 15Ks connected to 3 Power Pro’s and my 6 LL V2’s after I updated the firmware for the LL V2’s so that they can communicate with the PP...

DM sent

I found the answer in the QC (quality control sheet) from the factory. It’s 7.55 on one battery, 7.83 on the second, and 7.09 on the third. So with that information what number should I put in the discharge tab setup? Should I do an average?

Sounds like the Smart Home Panel is the problem to me. Have you noticed the complete redesign of the SHP with the SHP2. I had 2 Delta Pros, 4 xtra batteries, and the smart home panel (first one), the SHP was defective and fried one of DP’s, it took a month to replace the DP but ECOFLOW...

That's pretty cool thanks for sharing.

Great idea👍🏻👍🏻

At the 20 minute mark they describe the procedure for updating the firmware. The same will apply for the LL update

Yes and everything is running great. I had to get the amphenol connectors from Signature Solar to make sure they were the correct ones. Very happy with my setup

Following having the same issue and I'm a Glock armorer and have tiny screw drivers.

The amphenol connectors from EG4 are the some specs as the cable that come with the battery. You will have to use 2/0 cable with the connectors, and I had to first crimp with a 4/0 crimp and then a second 2/0 crimp for them to connect properly. I have 3 PP batteries and to top balance them I...

Nice specs on the panels.... I can see why you're considering going through the trouble to import.

Like i stated in my post the panel passed the wiring test every time. but when I would try to switch to battery power "pop" thats what I would here and then another DP would go down. They tried to blame my loads but that wasn't the issue and I proved that to them before they would admit the...

2” flex

Great detailed analysis... bravo my solar brother

I'm setting up a system very similar to the one Will is running is his shop with the new EG4 PowerPro batteries and a rack of EG4 LL batteries and want to get the same T-class fuse he is using on his system since I know it works. Anyone know?

I did all the DC side a little at a time. I just got the last piece if the puzzle for the AC side (fused disconnect) and my electrician should be able to do that install in a few days. Then my beast should be ready for real life trials. Gotta have the AC work done by a certified electrician...

I’ve been able to have closed loop with either battery bank. Even though Sol-Ark support will always say they don’t support closed loop coms with EG4 batteries. They’re taking to each other for me no problem. But to clear I never connect bother banks to the inverters at the same time it would...

Love the answer to fresh food and frozen food storage.... I'd roll with that answer on most of these. Most of this is on a need to know basis.

I understand code will vary depending on jurisdiction but how to ground the batteries in the rack shouldn't vary that much. Basically there will be 3 options 1. No need to ground (some have argued on another thread I started on FB EG4 users group that its a closed system and doesn't need to...

Thanks... that's what I thought from reading the manual when I first received the Sol-Ark but I had to wait 2 months on batteries to get this show on the road. Excuse the dumb question the answer is on the bottom of page 17. I should be fired :ROFLMAO:
