A free, client-side set of solar engineering calculators for batteries, MPPT controllers, wiring, inverters, and household loads.

Landing page captured for the 2026-08-29 issue.

Field notes

Inputs cover both electrical design variables and ordinary household appliance usage, allowing the suite to move from a daily-load audit toward battery, inverter, controller, and cable estimates. The topology instrument converts a target bank in kWh or Ah into whole battery counts, series strings, parallel strings, and terminal wiring diagrams. The MPPT module also checks temperature-adjusted Voc against controller ratings, while the wire tool supports both AWG and metric conductor sizes.
