MAIN 200AGenerator Installation in Sunnyvale, CA
Backup power only helps if the switching works when nobody is home. Automatic transfer switches, interlocks and battery systems all need to isolate from the utility cleanly, and that is where a bad install becomes dangerous for line crews as well as for you.

Situations we see in Sunnyvale
Not sure what size to buy
We meter and calculate rather than estimate. Most Sunnyvale homes land between 14kW and 26kW depending on AC, well pumps and electric ranges.
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.
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.

Reviews from Santa Clara County
Breaker tripped Sunday night and I got a call back in about ten minutes. Tech found a bad connection in a junction box behind the closet, fixed it that night, and the price was what he said on the phone.
Marcus D.Emergency repair · SunnyvaleStandby generator install. They sized it to what we actually use rather than the biggest unit, then walked me through the transfer switch and the exercise cycle.
Renee B.Generator · SunnyvaleFlickering through the whole house turned out to be a loose neutral at the service. They found it in under an hour when two other companies had shrugged.
Bill T.Troubleshooting · SunnyvaleGenerator Installation in Sunnyvale — questions
Do I need a permit to install a generator in Sunnyvale?
Yes, and often a gas permit too. We handle the electrical permit and inspection and coordinate with your gas contractor or plumber.
How much does a whole house generator cost in Sunnyvale?
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 Sunnyvale?
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.
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 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.
