GRID COMMAND

GRID COMMAND keeps one record of an off-grid power system: every component, wire run, load and manual in one place, for any brand of hardware. It runs in the browser and works with no signal. It draws an animated map of how the system is wired, estimates how long your appliances run on the battery bank, and tracks maintenance. It is free to try with no account; a paid plan adds a cloud backup and reading equipment labels from a photo.
