Do PV inverters need active power during night hours?

Although the number of PV installations is rapidly growing, the effective utilization of PV inverters remains low. As even if inverters are to operate in VAR mode during night hours, they still need some active power to compensate for their internal losses, regulate the DC bus and provide the desired level of reactive power.

Why do PV inverters stay idle at night?

For photovoltaic (PV) inverters, solar energy must be there to generate active power. Otherwise, the inverter will remain idle during the night.
