Energy capacity is not backup duration. The essential load and usable reserve decide what the battery can cover.
Backup time
Quick setups
7h30min
- Usable energy
- 13.5 kWh
- Constant load
- 1.8 kW
Starting loads, reserve and losses can shorten this estimate.
Backup clearer?
Cleange compares the inputs you enter; site, safety and contract decisions still need qualified assessment.
