"Ted did an excellent job installing a long 60A/240V line (6 gauge) from the house panel to our detached garage with a 60A disconnect ending in a Tesla Wall Connector. Communication through email worked perfectly, he was always on time, was thorough, used quality materials, worked efficiently, left the area clean, lined up the inspection, and charged a very reasonable fee compared to two other bids. I give my highest recommendation."

"We’ve had a great experience working with Alfonso. Always on time, very responsive, and communicates clearly throughout the process. He provided excellent suggestions and recommendations that really improved the outcome of our rebuild. He handled our tricky under-counter lighting installation with ease and also set us up with temporary power when we faced delays upgrading our panel with PG&E. The quality of his work is great, and he’s capable of handling any electrical need. Highly recommend!"

"Very professional, great work, and very willing to please. They removed all the knob and tube wiring and brought my house up to current code. And the great thing is, they were very reasonable in price, actually they blew all my other bids out of the water. Five generations of electricians, and it shows. I would recommend them to anyone. Thank you to you both for a great job."

"The team at Avant is next level. From planning, to prep and through final inspections, Avant’s skilled approach allows the home-owner to get from ideation to ”finished” without any pressure to do more than our budget allowed. We upgraded our panel; moved the PG&E drop so the wifi meter was no longer next to our master suite; installed a new EV fast-charger; installed a new home security system; upgraded indoor and installed new automated outdoor lighting AND re-wired all our 220a appliances. I’d recommend Avant for any home-owner seeking high value excellent workmanship!"

Generator Install questions, answered by experts

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.
