I have three EG4 Power Pro batteries and I always top balance my batteries prior to connecting. So I took a pair of battery cables from my PP batteries and added a 2/0 lug on the end without the Amphenol connector. I connected the Amphenol connector to a battery and then connected the 2/0 lug...

I asked pretty much the same question in the following linked thread and got a reply from the owner of EG4.... you would use the generator to power the Chargeverter. https://diysolarforum.com/threads/charging-eg4-power-pro-batteries-in-parallel-with-eg4-chargeverter-in-a-emergency.71293/

After updating the firmware on all the batteries they've been running great. I have recently had a few times when the inverter is sending energy to the grid with the batteries not at 100%. I'm about to do a experiment to see if its the BMS from the battery not communicating properly on...

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...

My system consists of two Sol-Ark 15ks in parallel, with 3 EG4 Power Pro's, and 6 EG4 LLV2's shared to both inverters. So far everything is working great. Had to do about 3-4 deep cycles (80% depth of discharge minimum) to calibrate the BMS between all batteries

I've been curious about the Ruixu batteries and the 15k as far as coms... you're having no issues at all? Are you off grid or still tied to the grid? If you are tied to the grid are you selling back excess energy when available?

Thanks

Make sure all batteries are up to date on firmware on both com ports, and that each battery is set to the Sol-Ark protocol. On the subject of the 2/0 cable part of your post…. You can either buy a 2/0 multi tap connector and extend each cable with 2/0 cable you will purchase Or Do what I...

Zero, I’d like to see what weird output readings you’re getting on the load side? Are you splitting the battery com to use Solar Assistant? By the way I also have 6 LLV2 batteries connecting with the three Power Pros and they’re all talking to the Sol-Ark. it took updating the firmware on...

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

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...

Thats what I figured

I've seen people talk about using the DB9 port on the sol-ark for SA and ditching the dongle but that make me wonder if a DB9 splitter could be used to connect both the dongle and SA via that port. I wonder if anyone has tried that before

My bad I thought he was responding to my post that was just info that I thought should be shared. Carry on

Not sure what this comment means?

With my system and being in fairly consistent contact with the head of R&D for EG4

Just a heads up if anyone is considering using Solar Assistant with the Sol-Ark 15k and the EG4 Power Pro batteries (they use the same BMS as the EG4 LL batteries) or the EG4 LL V2 batteries the splitter will cause BMS issues. Wish it weren’t so because I love SA and the frequency it poles the...

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...

Your direct connection to your batteries (not the hub connecting to the splitter) from the Pi.... what are the settings you're using in SA to see the battery data? CAN Protocol in the battery tab?

I have a master bus bar in the trough under the two Sol-Arks and everything connect to the bus bar. Battery banks, two groups, the 3 Power Pro's, and the rack of 6 LLV2's. They are all in closed loop. The Chargeverter will soon be connected to the main bus bar as well. Currently its...

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

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...

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...

The sleeper has not awakened 🤣

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

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...

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...

Did you use the smart home panel with your DP’s or did you use a non ECOFLOW transfer switch?

Will, If I've been paying attention you didn't need to put a soft start kit on your A/C for the EG4 18k correct?

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...

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...

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...

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...
