Hello Kevin, I have actual battery capacity of 670 ah’s programmed in. Do you have any theories on why 0 ah’s was helpful??
Swapping AC1 and AC2 is a really good idea. The only problem is since I put in a micro SD card to the Combox, to do extended logging, I have not been able to reproduce the problem that was easy to reproduce a month ago. Only thing that has changed is the weather has warmed up. Schneider tech support has been helpful with suggestions, but they will not pay to replace the battery bank…..
