Turn battery voltage and amp-hours into usable runtime while allowing for depth of discharge and conversion losses.
Estimated backup time
1.9 hours
The usable energy under your assumptions is about 0.77 kWh.
Real backup time can be lower due to ageing, temperature and high discharge rates.
Do not exceed the inverter or battery manufacturer's current limits.
Hours = voltage × Ah × DoD × efficiency ÷ load watts.
