Home Power

This section is for readers planning backup power, critical-load panels, solar batteries, generators, or home microgrids. It explains what can realistically run during an outage, how inverters and transfer equipment fit together, and why load planning usually matters more than buying the largest battery.

Questions this section helps answer

  • Which loads should keep running during an outage?
  • When is whole-home backup realistic?
  • How do inverters, batteries, transfer equipment, and solar charging work together?
  • What safety checks matter before connecting backup equipment?

How to use these articles

Start with a calculator or practical guide when you are planning equipment. Use news and market explainers for context, then verify local rules, equipment documents, and professional requirements before acting.
