And how many EG4 cables (as supplied with the batteries, 2/0 size, which is apparently good for 400A) do I need between my parallel batteries and my inverter? The inverter has a 250A breaker, and that seems to be the peak DC current, so is a single cable enough? I've seen more than one in some wiring diagrams, but it's not clear that's necessary... The built-in battery busbars are good for 600A, so there shouldn't be a lot of drop in the paralleling cables, no?

Only one set of cables would be necessary from battery bank to inverter. If multiple inverters are present, I would refer to following the diagrams.
Maybe someone could help me. I am paralleling 4 EG4 Powerpro's so they all have to connect to a busbar. The longest length from a battery to the busbar is 12 feet, so all conductors must be 12 feet to keep equal lengths.
Currently I have 4/0 conductor from a busbar to an existing battery that I am replacing with the 4 EG4 models. What size conductors will I need to get from the busbar to each of the 4 Powerpro batteries? The batteries came with 2/0 that are way too short.
I would like to go 4/0, but I don't see any amphenol connectors for that size.
Any ideas?

I went through this as well they don't have any 4/0 connectors. Signature solar told me that those connectors are proprietary to that battery not standard amphenol. The connectors they sell are only 2/0 the other option you can order the connectors they have on signature solar website and double up the cables. Correct me if I'm wrong but I think it's the inverter cables that need to be the same length I don't think it's as important for the battery. I see on Wills videos he has all sorts of battery banks hooked up with different length cables.

Not an expert, but I think when paralleling batteries it's ideal to have the cables be the same lengths. Beyond that it's "better" but not as essential.I went through this as well they don't have any 4/0 connectors.

It would be nice if they stated in the in the link above what the max wire size is.I went through this as well they don't have any 4/0 connectors.

I made my own cables with 2/0 Welding Cable Class K. I purchased the connectors from Signature Solar.
Two of these cables go from my PowerPro's to my 18kpv.

I had to try a few different hydraulic crimpers to get the connections made. You need a larger crimper that can go up to 4/0. I never found the perfect crimper size and ended up starting at 4/0 and working down to either 3/0 or 2/0+. I can't remember but just order a crimper that can handle in that range.
Yes I agree, I actually called them and they check to see if they could get a 4/0 cable in that connector. They said they could only get a 2/0.

It looks like there are openings at the bottom of the battery that you could run the parallel wires through. If you had one battery mounted over the other, is that correct?
All of these posts are great when they consider that you use the Powerpro batteries with one or more EG4 18k inverters. Now, how do we effectively parallel 4 or 5 Powerpro batteries with two sol-ark 12k's? On the EG4 inverters they have a few more battery connections.
What is the best way to go about wiring them up with other inverters?
I though I would only need 4 Powerpro batteries. But after having 3 connected I realize I am going to need more, so maybe I am ordering two more instead of one. Of course this depends on my ability to get them wired together properly.

I think it would be ok to parallel all 5 batteries with the EG4 cables and then feed each 12k from 2 different points in the battery chain.
12k-1 to battery 2, 12k-2 to battery 4 for example.
12k-1 to battery 2, 12k-2 to battery 4 for example.

Don't see why not, they don't even talk about inverters, just WM-48-280-6- IN-LL-00 and the charge/discharge currents thereof. Looks like at 70 amps per battery you are well within the 600A built-in busbar ratings as well.

I would refer you to this link which goes over the variety of configuration options with UL9540: https://eg4electronics.com/backend/...0-Detailed-Configuration-Requirements-1.1.pdf

So does the fact that (2) 18KPv inverters and (6) PowerPro batteries isn't in the document mean:
1) It doesn't work for some Code reason
2) It doesn't work for some Technical reason
3) It wasn't tested/certified (yet?)
I mean, you've got (1) 19Kpv and (3) PP, so why not double?
I mean, I bought the kit from SS, so we have some reason to believe it'll work, and if it's just not UL9540 then that's not a problem (for me).

It has not been certified for more yet. Two 18kPV's and six WallMount batteries will work well together.
