Electrical power/ CALCULATOR
Battery runtime from a steady load
Estimate ideal runtime from nominal energy, usable fraction, inverter efficiency and load.
Use the rated energy capacity of the battery bank.
Keep the intended reserve outside this fraction.
Average load during the runtime period.
Combined delivery efficiency for this estimate.
Energy delivered to load
7.20 kWh
Ideal runtime
14.40 h
Constant load and efficiency with the stated usable fraction. Temperature, ageing, standby consumption, peaks, battery-management cutoffs and capacity-rate effects are excluded.

Electrical power
Inverter DC input current
Convert an AC load and inverter efficiency into approximate battery-side power and current.
Electrical power
Inverter running and motor-start screen
Compare one documented motor start plus other loads with derated continuous and surge inverter ratings.
Electrical power
DC cable area for a voltage-drop target
Estimate the copper conductor area needed to keep steady DC voltage drop below a chosen percentage.
