Service 03

Generators · Sized for the outage you actually get.

Windstorm season takes down power for hours, sometimes days. We size backup around the circuits you actually need — heat, well, fridge, network — and test the transfer under load before we hand it over.

Scope

Automatic standby generators, 11kW – 26kW
Battery backup: Tesla Powerwall, Enphase, FranklinWH
Automatic and manual transfer switches
Critical-load sub-panels
Solar-coupled backup integration
Annual service and load testing

Gas coordination, pad, permit, and inspection handled end to end.

Questions we get

Generator or battery?: Battery is quiet and instant but finite. Generator runs indefinitely on gas. Many homes we serve use both.
Will it back up the whole house?: It can, but a critical-load panel is usually the better value. We model both before you decide.
