So still working on the firmware update issue. However I have more issues.
When charging from the grid, AC in, the batteries don't charge. I left it running for a week and it didn't charge the batteries at all. Granted I was only letting it run from one inverter. It was suggested that I need to have two inverters to charge the battery from grid, is this right?
Another problem, when I turn on the second inverter, it gives me an alarm with code 61. I have the communication cables connected to the first inverter, the one I was using to charge them. I also have the black and red wires, as well as the DB9 connectors between the two inverters. I can't figure out what is wrong with it, I'm hoping that a firmware upgrade will solve this.
If you have 2 inverters running in split phase, you wouldn’t use the black and red current sharing cables.
