You are overlooking this: “No more than 40kWh in any one location. Location being: 1) Inside house; 2) Garage; 3) outside house.”
I'd rather have one rack of 15kwh on fire than two racks of 15kwh on fire, or even one rack of 20kwh.
And I’d rather have my 12x12 power shed on fire than my 48x36 finished shop, my moms house, or other outbuildings.

I'll give it some love. Just installed one of two - next one will go up this week. Very straight forward with the SolArk 15. Also can be mounted outside. It is heavy but the total cost is comparable to building your own rack mounted once you add in cabling etc. Easy comms with Sol-Ark (although it is not officially listed on the Sol-Ark battery list - Sol-Ark claims to be battery agnostic and it worked on first hook-up)
No battery wires? This is the new "wireless" version?
LOL - You haven't heard of the invisible 2/0 cables? Pic taken before final completion. The EG4 Power Pro came with some cables but they were too short - designed to work with their EG4 18 Inverter mounted right above it. I live in the woods - we butcher whatever walks through that looks tasty
. I agree that the wires coming out of the top don't sound like the greatest idea. It is, supposedly, outdoor rated and they are amphenol connectors at the battery. Nonetheless Ill probably build a little shed roof over it and/or add a raceway.
One thing to consider is that Sol-Ark doesn't currently support closed loop communication with the EG-4 PowerPro. I learned that a bit late as they advertise the Sol-Ark 15 Limitless as "battery agnostic". I initially programmed it to "BMS Lithium" code 00 on the Sol-Ark and it seemed fine, but when I emailed Sol-Ark they said it wasn't approved and to un-select Lithium and just use Batt %.
A number of people have reported unpredictable behavior using % without comms. Without comms you may need to use V and not %. YMMV.
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?
No issues at all. Have been running for about 3 months now.
@muaddib721 Nice install. Did you use the raceways EG4 sells and then custom run the cables over to the Sol-Ark 15? What battery setting did you use on the Sol-Ark? @Oldphile are you suggesting using the comms and the "Batt Lithium" option on the Sol-Ark. When I first set it up I did that and "battery type". 00. (Sol-Ark has published a list of their tested batteries and has a bunch of info but sadly doesn't have EG4)
Not suggesting that you use comms. I'm suggesting that you use voltage and not %.
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 runs with all my batteries and here is the second and third cycle data. Also cycle 4 so far
Wow, nice data. Thanks for posting.
