Apparent power (KVA)

Power factor (0–1)

Motors often 0.7–0.9; resistive loads near 1.0

Reactive power

6.32 kVAR

Reactive power

In plain terms, that's 6.32 kVAR.

10.2 kW

Real power

kW = kVA × PF. Reactive power kVAR = √(kVA² − kW²). Poor power factor increases current without delivering useful work.

Inverter and breaker ratings must cover apparent power (kVA), not just real watts. Include reactive kVAR in project BOM when quoting AC distribution.

kW = kVA × PF. Reactive power kVAR = √(kVA² − kW²). Poor power factor increases current without delivering useful work.

Inverter and breaker ratings must cover apparent power (kVA), not just real watts. Include reactive kVAR in project BOM when quoting AC distribution.

kVA to kW ConverterConvert apparent power (kVA) to real power (kW) using power factor.Use this to see how much usable power you really get from a generator or transformer.
Power Factor CalculatorCalculate power factor from real power (kW) and apparent power (kVA).Use this to see how efficiently your equipment uses power and avoid utility penalties.
Inverter SizingFind minimum inverter size from peak load and safety margin.Use this to choose an inverter that handles your loads with room to spare.
Amps to WattsConvert current (amps) and voltage into power (watts).Use this to figure out how much power your gear draws and what it costs to run.
