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.

Datasheet and manual

Check it fits your design

Specifications change with revisions and firmware. Confirm the exact model with the manufacturer, then check the battery voltage, charge current, MPPT window and communication protocol against the rest of the system.
