How long will it run a refrigerator?

Runtime depends on the fridge's draw and the battery capacity attached. A typical fridge averages a few hundred watts, so the base unit plus a Battery Pack 3600 can carry it for many hours, but check the fridge's rated watts before relying on it.

Can I add more batteries later?

Yes. The HomePower 3600 Plus accepts Battery Pack 3600 expansion units, so capacity can grow over time. Each pack adds runtime rather than output power.

Will it power my whole house?

No. It is essential-circuit backup, not a whole-home system. It handles a fridge, lights, router, phones and small medical devices, but not central AC, electric ranges or electric heat.

How is it different from a gas generator?

It runs silently with no fuel, exhaust or maintenance, and it can sit indoors. A gas generator delivers more continuous wattage for heavy loads but needs fuel and outdoor placement.

Does it need professional installation?

It is a plug-in unit, so no transfer switch or electrician is required for basic use. For hardwired circuits, an electrician may still be needed to connect a transfer setup.
