SolarCalcKit’s Six-Instrument Solar Sizing Suite
A free, client-side set of solar engineering calculators for batteries, MPPT controllers, wiring, inverters, and household loads.
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.
