Size a solar DC fuse from Isc, strings, panel limits, and wire ampacity, with a safe-window check.

Size a DC solar cable by current, distance, voltage, voltage drop, material, and temperature with AWG and mm2 results.

Estimate grid-tied solar inverter kW AC from panel watts, panel count, target DC:AC ratio, and common inverter sizes.

Estimate battery internal resistance from open and loaded voltage, then check sag, heat, efficiency, and a planned load.

Find charger amps, charge time, common charger size, and C-rate using battery Ah, target charge, efficiency, and safe limits.

Estimate home battery runtime for outage loads and optionally compare running and startup demand with the system power limit.

Estimate usable kWh, battery units, runtime, and optional peak power needs for a home outage backup plan.

Estimate solar charge time from battery Wh, charge level, panel watts, station input limit, sun hours, and running load.

Size a portable power station in Wh and W from your device list, with optional model and solar checks.

Estimate power station run time or needed Wh with efficiency, reserve, idle draw, and outlet watt limit checks.
