"Sergio did a fantastic job! Very happy with the clean install of my tier 2 charger and he added a plug down below my panel. Would recommend for any sort of EV charging installs! Clear communicator, showed up when he said he would and his services were well-priced!"

"Highly Recommended! We have hired Zero Electric to do several jobs at our apartment complex including installing a generator, EV chargers, new panel, and even installing recessed lighting in the units. They handled all aspects of the projects and had top notch communication throughout. The team has always been quick and professional. We will continue using Zero Electric for our electrical needs."

"They are knowledgeable and installed the car charging station in my garage. I had compared with other companies who seemed to be cutting corners, and I felt McKee was doing things the right way so I chose them. His communication was good, he was on time, and followed through on what he said he would do. Good, clean, and professional. I intend to have him back out for my next electrical project."

Generator Install questions, answered by experts

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.
