Energy Loom

Energy Loom helps you understand a small household backup-power plan before an outage or equipment conversation.

Build a clear load list from the watt labels on lights, phones, routers, fans, laptops, refrigerators, pumps, and other devices. Set how many hours each load should run and mark it as essential, important, or flexible.

Add your battery capacity, usable-depth limit, inverter efficiency, solar-array size, and expected peak-sun hours. Energy Loom then estimates:

- daily energy demand in watt-hours;
- possible running-watt peak;
- usable battery energy after losses;
- approximate backup reach;
- conservative daily solar harvest;
- which planned loads fit when essentials are protected first.

The 24-hour Energy Weave makes the result easier to read. Amber shows requested run time, while teal shows the time supported by the current battery assumptions. Every visual result is also available as text.

Your plan stays on your device. Core features work without an account or internet connection. There are no ads, purchases, subscriptions, analytics, or location tracking.

Energy Loom is an early planning aid, not an electrical design or installation tool. Battery chemistry, surge loads, wiring, fuses, breakers, charge controllers, and equipment limits must be checked against manufacturer guidance and verified by a qualified installer.
