Power Backup Duration in Africa — Planning Your Energy Independence
With frequent power cuts across Africa, knowing your backup duration is essential. This calculator accounts for inverter efficiency (90%) and battery depth of discharge limits — the two factors most people ignore when sizing their backup systems, leading to shorter-than-expected runtime.
Disclaimer: Actual backup time depends on real load profile, temperature, and battery age. New batteries perform closest to these estimates.
