Inverter Battery Backup Time

My inverter is not giving sufficient backup.

Inverter battery backup time.

380 x 6 12 190ah. Similarly the battery is an integral part of the inverter. For further information we recommend reading our buying guide. This is the most common complaint raised against the home inverter system.

Backup time battery ah x 12v x n x efficiency of battery load in watts. 1 ceiling fan 75 watts. The inverter system also has some charging system that charges the battery during utility power. The battery backup time in hours can be calculated using following formula.

To help you make the right purchase we have. Similarly battery is an integral part of the inverter. We expect maximum backup time from the inverter system with a tubular battery but unfortunately we get half or less backup time than we expect. The inverter system then converts the battery voltage to ac voltage through electronic circuitry.

Inverters convert dc voltage to ac voltage. Battery size inverter va rating x usage time in hours input voltage. If you wish to have a backup for 6 hours with a 380 va inverter and battery input voltage of 12 v the total battery size would be. The performance of the inverter depends on the connected battery and vice versa.

Where battery ah ampere hour capacity of battery. 1 tube light 40 watts. Back up time of inverter battery battery volt x battery ah rating total watts on load so if a person use 1 ceiling fan 1 tube light 2 15watts cfl simultaneously with 150 ah battery then the backup time will be calculated as. They have a battery system which provide adequate backup time to provide continuous power in the home.
