Hi There. What is wrong when the watts is low on one bank of panels but the volts is good.
We have 48 panels of 265watt on the system. 4 x 5kva axpert 48v inverters. 12 panels per inverter. Now the problem we see is that 3 of the inverters gives good watts reading but one inverter gives low watts reading. The volts input from panels on all 4 inverters individual is around 126 volts.
For example the reading input on watts on 3 inverters is around 2100watt and 1 inverter is around 350 watt.
Please comment
