What this calculator does
Focuses on storage kWh/Ah needed when panels are off — aligned with Pakistan's shift to evening self-consumption.
How calculations work
- Uses night load (W) × backup hours plus safety margin.
- Recommends 48V-class storage where hybrid inverters are common.
- Links to AmpereX solar datasheets and use-case guides.
Examples
500 W night load, 6 hours
≈3 kWh usable → 48V 65Ah+ LiFePO4 class configuration.
Common mistakes
- Sizing only for panels, not night load
