How to read this record
- Continuous output is what the inverter can hold for hours. Surge is a short overload for motor starts and is often double the continuous rating.
- Battery voltage fixes the bank topology. A 48 V inverter needs a 48 V bank, and the charge current must be within the battery's limit.
- Maximum PV voltage and the MPPT window are different limits. A string can be inside the MPPT window and still exceed the maximum PV voltage when cold.
