What capacity of battery for 20kva ups 30 minutes backup time?

To determine the battery capacity needed for a 20 kVA UPS to provide 30 minutes of backup time, you first need to convert kVA to kW, assuming a power factor of 0.8, resulting in 16 kW. For 30 minutes of backup, you would calculate the energy requirement: 16 kW × 0.5 hours = 8 kWh. Therefore, you would need a battery capacity of at least 8 kWh, but it's advisable to consider additional capacity for efficiency losses and battery discharge characteristics, so a battery rated around 10 kWh would be recommended.
