I think my EG4's are still sitting at Signal Solar even though I have had a tracking number for days now. If that's the case they won't be here by this weekend unless I go get them. Frustrating.
As soon as I get them and can do some testing myself, I will hopefully be able to determine what's going on better. The thread is long and it's hard to understand every troubleshooting step
@Koldsimer has tried, which he has tried a LOT of things to try to make these batteries work with his inverter.
I'm very anxious to hear back from Signature Solar on this also....
