Backup Power Calculator

Build the outage scenario first. PowerPilot calculates the battery and inverter requirements before it compares products.

Backup power, sized from your actual loads

What do you need to keep running?

Select your essentials, set an outage length, and PowerPilot calculates energy, inverter output and startup surge before comparing only electrically compatible stations.

Location-aware solar simulation

Optional. If you provide coordinates, PowerPilot can run a PVGIS off-grid battery simulation after the basic calculation.

Results are specification-based estimates. PowerPilot applies efficiency, usable-capacity and reserve assumptions, then rejects models that fail hard electrical requirements.

Technical fit comes firstAffiliate value cannot turn an incompatible station into a recommendation.

Runtime is an estimateUse exact appliance measurements whenever the load is safety-critical.

Solar can be location-awareOptional PVGIS modelling adds historical solar-resource context.
