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 backup runtime with reserve charge, inverter losses, battery wear, idle draw, and a backup time goal.

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.
