I had the same question and got an excellent response from Shaun at Sol-Ark: The 15K-2P-N reaches a max battery charge/discharge of 275A if using both sets of battery terminals. If only one set of terminals is used, the max battery charge/discharge will be limited to 160A. If you have x2 (#2/0...

This project isn't complete yet but you see where it's going. You don't HAVE to stack the EG4 Power Pro batteries under the EG4 inverter. You can use them with almost any inverter - in my case the Sol-Ark 15 which I much prefer to the EG4. I did have to custom fab some 2/0 cables with Amphenol...

I have a SolArk 15 and plan on using two EG4 PowerPro (Lithium Iron Phosphate) 14.2kW batteries with a 10.4kW solar rooftop array, I went with the EG4's to keep it simple and because they can be externally mounted next to the SolArk 15. They are heavy (300#) but easy to parallel. Building...

I also have EG4 Power Pro Batteries. Works well. One thing to calculate first is how much cabling you will need to attach the "master" EG4 Power Pro to the Sol-Ark 15. The batteries use Amphenol Connectors and the Sol-Ark uses 2/0 wire with 3/8 lugs. You need TWO wires to run from the last...

Thanks. That's what I had it set at and it seemed happy.

Wow, nice data. Thanks for posting.

Then, sometimes, it just disappears

Correct. I have two EG4 power pro 14.3 Kwh batts and they are almost perfectly built to hook up to the Sol-Ark 15 in that you run one (each - pos/neg) 2/0 cable with Amphenol style connectors to each battery to parallel the batteries and then two Amphenol style to ring connectors (two pos and...

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...

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...

I went for the EG4 PowerPro. If you run two together in parallel then run double cables to the battery inputs on the Sol-Ark 15 you can maximize the 275 amp capability of the Sol-Ark. They are heavy but can be mounted outside and are LiPo4 so some ease of mind with regards to 100%-0% charge...

More than likely you are looking at service entrance wire for a 200 amp house. That stuff is big and probbly impossible to put connectors on to attach to a battery. Equal ampacity copper will be smaller and easier to handle...

I use the manual Temco product (others sell a similar version). It works well. If you're close you can borrow it. I need to be somewhat portable for boat work but the hammer version would work for just a few crimps you could do on a bench...

I believe they are 3/8 in lugs so if you had a 4/0 terminal with a 3/8 in hole it would work but you would still need two to hook up to both of the inputs (actually four, two + and two - ) if you wanted to get the max 275 amp rating

@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...

I'm having an odd issue with my Sol-Ark 15k. Currently, it is grid tied and I have 4 strings of PV panels using an AP Smart RSD. The AP Smart RSD has its own power supply run to a 240 volt dedicated breaker in my main panel. (Aside - small issue for those considering Sol-Ark: they do have a...

The 160 amp / 275 amp comment probably relates to using 2/0 wires to hook up the battery to the Sol-Ark. If you only use one you can only get 160 amps. If you use two you get the full 275 amps. It was easy coming from my EG4 Power Pro batteries as they have 4 connects to both pos/neg so I...

@Sennen Super helpful and detailed post - thanks. Can you tell us how you programmed the Sol-Ark settings? What "Battery type" did you choose and what boxes did you check ( you click BMS Lithium Batt you get an option to choose batt type 00 through 06)

Looks like you have done your research. I'll throw out a simpler and less costly option but it requires human intervention occasionally. Forget about all the critical loads panels and everything else and get one Sol-Ark 15 Inverter and set it up to power the whole house. The automatic...

It does seem sketchy sometimes but then seems to fix itself. Is the consensus that getting Solar Assistant is a good idea? For the life of me I have trouble navigating Power View and sometimes waiting the 5 min for it to re-set is maddening. Slightly off -topic but since everyone on this...

That's a great question. The Sol-Ark manual doesn't really explain the pros/cons of activating Arc Fault. Any experts out there? Unfortunately, if you DON't have it checked it's not the likely culprit of your problem :-(

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...
