Backup power has value beyond bill savings. Confirm usable capacity, inverter limits and warranty cycle terms separately.
How we calculate it
Input kWh × cycles × (round-trip efficiency × peak rate − charging rate). Assumes all discharged energy displaces peak purchases. Excludes battery ageing, financing and maintenance.
Results describe the scenario you enter. They are estimates, not a quote or a guaranteed reduction in your utility bill.
