| As a side note, I just swapped a pair of 12k MCU boards. Pretty easy for the 12k and I left them hanging on the wall but completely shutdown. That’s a great time for an AC bypass. The MCU board has the device ID, aka inverter serial number. So, when you swap them out, you’ll need to re parallel the group and likely with Sol-Ark on the line. Then, the old “inverter” will show as disconnected and if you don’t need its historical data, it can be deleted.
