Battery energy storage beside solar arrays

BACKUP DESIGN PREVIEW

Size resilience with intent.

Estimate battery energy and power for essential loads, target backup duration, efficiency and usable depth of discharge.

BATTERY & BACKUP PLANNER

What must stay running?

Essential load (kW) Backup hours

Usable depth of discharge (%) Round-trip / inverter efficiency (%)

Engineering reserve (%) Peak / motor start multiplier

This is a first battery-size estimate. The final system also accounts for starting loads, usable battery capacity, temperature, equipment compatibility and electrical safety.
