Can someone help me identify which version of the EG4 LLs are shown below? The manufacturer site doesn’t have much in the way of documentation of the various versions that were produced prior to the current version. I have two of the older LLs and a newer version (3 total) in an open loop communication to a Sol-Ark 5k. I’ve never done a firmware update on any of my batteries, mainly because I didn’t realize there were any until the other day. But since I don’t know my battery version I don’t know where to get the files.

I’m considering buying an EG4 WallMount to run in parallel to my current battery bank. I assume connecting both banks to a fused bus would work in my current setup. Is there a particular bus setup that you all could recommend? Thanks in advance!

So would I be able to parallel these version 1 battery bank with a wallmount? The bank is 300 Ah capacity and wall mount is 280 I think?
