MAIN 200AGenerator Installation in Napa, CA
A standby generator that runs your whole Napa house is a different machine from one that keeps the fridge, the furnace and a few lights alive. Rupert Electrical Solutions starts with a load study so you buy the right size instead of the one on the showroom floor.

Situations we see in Napa
Existing generator won't start on outage
Usually the transfer switch, the battery or the exercise routine, not the engine. We diagnose the switching first.
Extension cords through a window
Common and genuinely dangerous. An inlet box and interlock costs a fraction of a standby unit and ends the practice.
Whole house or essential circuits
A critical-load subpanel is far cheaper than whole-house coverage and keeps heat, refrigeration and internet running. We price both.
Not sure what size to buy
We meter and calculate rather than estimate. Most Napa homes land between 14kW and 26kW depending on AC, well pumps and electric ranges.

Reviews from Napa County
Smart switches wouldn't work because there was no neutral. They pulled one, got everything on Lutron, and set up the scenes before leaving.
Chantal P.Smart home wiring · NapaGFCI in the bathroom kept tripping. They found real leakage in an old fixture rather than just replacing the GFCI and calling it done.
Nadia F.GFCI repair · NapaWarehouse high bay retrofit to LED. Did it over a weekend so we never stopped shipping, and the place is twice as bright.
Greg L.Warehouse lighting · NapaGenerator Installation in Napa — questions
How often does a standby generator need service?
An annual service plus the weekly self-exercise cycle. The exercise routine matters more than owners expect, because it is what catches a dead battery before an outage does.
Do I need a permit to install a generator in Napa?
Yes, and often a gas permit too. We handle the electrical permit and inspection and coordinate with your gas contractor or plumber.
Will the generator start automatically when the power goes out?
With an automatic transfer switch, yes, typically within 10 to 30 seconds. With a manual switch or interlock you start it and flip the switch yourself, which is a cheaper install.
How much does a whole house generator cost in Napa?
The unit is roughly half the project. The rest is the transfer switch, pad, gas line, electrical and permit. Sizing drives everything, so call (833) 652-8933 and we will run a load study before quoting.
Can you install a battery instead of a generator in Napa?
Yes. Battery backup runs silent, needs no fuel and pairs with solar, but has a fixed energy budget. For multi-day PSPS events a generator still wins on runtime.
