One installer puts all five on your PC in minutes. Python is handled automatically — if your PC doesn't have it, the installer sets it up silently.
Size your solar array, battery bank, wiring, fuses, and inverter — with every step of the math shown.
Protect the most expensive part of your system — batteries die from neglect, not age.
For the cloudy weeks solar can't cover — size it right and know what it costs to run.
Water is the second pillar of off-grid living — know your supply before the dry month hits.
Size your winter — and know whether you're short on wood before January.
