How to read this record
- Voc is an open-circuit voltage, not the operating voltage. String voltage must be checked at the coldest expected temperature.
- Vmp and Imp are the operating points the MPPT will track. Isc is a separate limit some inverters specify separately.
- The temperature coefficient changes voltage on hot and cold days, so a string that looks safe at 25°C can exceed the inverter limit on a cold morning.
