Wattstanding puts outage math on the shopping list
A home-backup-power reference that calculates appliance loads and runtime, then compares power stations, generators, transfer switches, and solar equipment.
- For
- Homeowners planning outages and comparing backup-power equipment
- Worth noticing
- The sample 2,000 Wh model assumes 85% usable capacity and labels appliance draws as typical, not guarantees.
Field notes
The sample calculator uses an 85% usable-capacity assumption and calls appliance wattages typical, so its runtime figures are estimates rather than guarantees for a reader's specific devices. Equipment listings are organized around practical comparison points such as battery chemistry, generator fuel and stated noise, transfer-equipment amperage, and solar energy by region. The page notes that transfer-switch installation is for a licensed electrician.
