A GM Energy system pairs bidirectional charging hardware with transfer equipment that can isolate your home from the grid and draw power from a compatible EV battery. For Placer, Nevada, and El Dorado County homeowners who lose power during PSPS events or winter storms, that means a backup option that doesn't rely on fuel storage or a generator startup cycle. King Electric and Solar handles the electrical side: panel evaluation, dedicated circuits, permits, and PG&E interconnection.
Every installation starts with checking your specific vehicle and equipment, then evaluating your home's electrical system before any quote is finalized.

A working vehicle-to-home system depends on the right vehicle, the right equipment, and an electrical panel that can support it. Here's how we get there.
Bidirectional capability depends on the specific GM vehicle and charging equipment involved. We confirm compatibility before quoting anything.
We review your main panel, available service capacity, existing circuits, and priority loads to determine what the home can support.
We plan conduit routing, equipment placement, and required clearances so the system fits your property and meets code.
We handle the permit application and PG&E interconnection paperwork required for grid-isolating backup equipment.
Once approved, we install the dedicated circuits and transfer equipment, then test the system to confirm it operates as designed.

Q1
Yes. We handle the electrical side of GM Energy installations, including panel assessment, dedicated circuits, permitting, PG&E interconnection, and commissioning. Contact us to confirm current program details for your specific vehicle.
Q2
It's a system that combines bidirectional charging equipment with transfer and control gear, allowing a compatible GM EV battery to supply backup power to your home when paired with home energy storage components.
Q3
It depends on your specific vehicle model and the installed equipment. Bidirectional capability varies by GM vehicle, which is why we check compatibility before providing a quote.
Q4
Runtime depends on your vehicle's battery capacity, your home's electrical loads, and which circuits are backed up. We review your specific setup rather than quoting a general number upfront.
Q5
Often yes. Many households keep a standard charger for daily driving and add the bidirectional equipment separately for backup use. We can plan out both during the same visit.
Q6
Older or already full panels sometimes need an upgrade before this equipment can be added safely. We assess your panel's service capacity as part of every evaluation.
Q7
Yes. Grid-isolating backup equipment requires permitting and PG&E interconnection approval. We manage that paperwork as part of the installation process.
Q8
A vehicle-based system can offer more stored capacity than a typical wall battery, but using it for home power reduces driving range. Households needing both daily vehicle use and multi-day backup may be better served by a generator or a dedicated home battery.
