Path-Q Solar

Which appliances should be connected to backup power during an outage?

Answer

Prioritize safety, communications, refrigeration, medical equipment, lighting, water systems, and other loads whose outage creates significant harm; add comfort loads only if capacity and runtime allow.

Key points

  • Separate essential from discretionary loads.
  • Check continuous demand and startup surges.
  • Heating, cooking, pumps, and water heaters can dominate capacity.

What it depends on

  • Health and safety needs
  • Appliance power requirements
  • Desired runtime and battery or generator capacity

Risks and trade-offs

  • Whole-home backup can be costly.
  • Too many connected loads can overload the system or shorten runtime.

Information you may need

  • Essential appliance list
  • Nameplate and surge ratings
  • Required outage duration

Your next step

What to do next

Create a prioritized load list and have the installer verify its total continuous and surge demand.
