Power outages in the foothills tend to last longer than they do in the valley, especially during fire season or winter storms. Our electricians assess your home's electrical load, recommend the right battery capacity, and handle the full installation from panel connections to system programming, so your home stays powered when the grid goes down.
A whole home battery backup system needs proper sizing, safe wiring, and coordination with your existing panel or solar setup.

We walk through each installation step by step so you know what to expect before, during, and after the work is done.
We review your electrical panel, current usage, and which circuits matter most during an outage, whether that's your fridge, well pump, or medical equipment.
Based on your home's needs, we recommend a battery system sized to cover your priority loads, and outline how it will connect to your panel or solar array.
Our electricians install the battery, transfer switch, and any required panel upgrades, following safe wiring practices for a system that performs when you need it.
Once installed, we test the system under load, confirm automatic switching works correctly, and walk you through how to monitor and manage it.
Get clear answers about whole home battery backup, preparation, timing, maintenance, and what to expect before requesting an estimate.
Q1
It depends on your battery capacity and how much of your home you're backing up. A system sized for essential circuits like refrigeration and lighting can last much longer than one running your entire house. We size the system during the design phase to match your needs.
Q2
Yes, in most cases we can integrate a battery system with an existing solar array so it charges from your panels and provides backup power during an outage. We assess your current solar setup before recommending equipment.
Q3
Some homes need an electrical panel upgrade to safely support a battery backup system, especially older homes in Auburn and Grass Valley. We check your existing panel capacity as part of the initial assessment and let you know if an upgrade is needed.
Q4
An automatic transfer switch monitors your utility power and switches your home to battery power within seconds of an outage. There's no manual flipping of switches required once the system is installed and programmed.
Q5
Most homeowners prioritize refrigeration, well pumps, medical equipment, lighting, and internet or communication devices. We go through your circuit list with you to decide what makes sense for your household and budget.
Q6
A standard whole home battery backup installation usually takes one to two days, depending on whether panel upgrades or solar integration are involved. We give you a specific timeline after the home assessment.
Q7
Yes, we install battery backup systems throughout Placer and Nevada counties, including Roseville, Rocklin, Folsom, Lincoln, Grass Valley, and Nevada City.
