Performance

Performance 1
If the solar array is installed on a domestic dwelling and connected to a grid inverter, Is the array’s maximum voltage VoC array max (at minimum temperature) less than 1000V DC or 1500V DC for all other electrical installation types (for example, commercial)?

Applicable rating: Needs rectification

Performance 2
Is the PCE PV input voltage rated to at least the PV array max voltage (at minimum temperature) of the circuit that is connected?

Applicable rating: Needs rectification

Performance 5
Calculate system parameters based on configuration – confirm DC isolators on roof and at ground meet minimum requirements and array configuration is suitable for inverter optimal operation.

Applicable rating: No rating is applied

Performance 7 ***UPDATED***
Are the estimated AC wiring losses more than 2% between the inverter terminals and the point of supply, taking into account any generation supply limits?

Applicable rating: Improvements identified
