Posted April 14, 20231 yr Good day , I have two by 8 PV Strings. On PV1 I get 50 % less output voltage compared to PV 2. When I change PV1 string with PV2 input on the inverter ,I get the correct input. And the PV2 string into the PV 1 input on the inverter then drops to 50% compared to the input at PV 2. Any ideas on what is causing this. Is the PV1 input on the inverter having a problem?Any ideas would be appreciated.
