A ha. That explains it. Some how the EG4 inverter monitor on your end got switched from an 18KPV to a 12KPV. Everything on my end points to the inverter being a 18KPV (which it is). I looked at the inverter display and nothing I can find describes it to be a 18KPV. It does shoe 3 MPPT inputs and displays all the date for them. Again I think the problem is on your end and is mis identifying the serial number as being an 18KPV. Please keep looking.
