When the power goes out, your options fall into two camps: a standby generator (usually natural-gas or propane, wired to a transfer switch so it starts automatically) or a battery backup system (often paired with solar). A generator can run larger loads for longer as long as it has fuel; a battery is quiet, low-maintenance, and clean but is sized to a budget of stored energy. The right choice depends on which circuits you need to protect, your fuel or solar situation, and whether you want whole-home or just-the-essentials coverage.

What to know

  • Standby generators start automatically via a transfer switch and run on natural gas or propane.
  • Battery backup (often with solar) is quiet and low-maintenance but sized to stored capacity.
  • Decide what must stay on — fridge, medical equipment, heat — to size the system honestly.
  • Both require a licensed electrician and proper permitting; we handle the panel and transfer-switch work.
