6 FAQs about [Photovoltaic inverter reactive power consumption]

Can a multifunctional PV inverter support reactive power?

Therefore, the multifunctional PV inverter can be applied to support this load with reactive power. However, the employed PV inverter rated apparent power is 5 kVA, which means that it can only compensates at maximum 5 kvar. Therefore, the reactive power profile used as input of the multifunctional PV inverter is shown in Fig. 12 (a).

Do PV inverters provide reactive power during nighttime?

In general, PV inverters can provide reactive power during nighttime and during daytime. During nighttime, inverter losses are attributed entirely to the reactive power generation and are generally higher than specific losses due to reactive power flows in the distribution system.

Does reactive power capability affect PV inverter reliability?

From the unreliability map, the multifunctional PV inverter specification in terms of reactive power capability can be defined in accordance with reliability assessment. Finally, the economic analysis based on LCOE showed that reactive power capability increases the system costs due to more inverter replacements.
