Keep Power Available When the Grid Goes Down

Shadowfax Roofing & Solar installs battery backup and energy storage systems for homes in Campbell, California.

When the power goes out in Campbell, whether from planned maintenance, grid strain during high demand, or equipment failure, a battery storage system lets you keep essential circuits running without relying on the utility. Shadowfax Roofing & Solar installs battery systems that store energy from your solar panels or charge from the grid during off-peak hours, then supply power to your home when it is needed most.

Battery systems work with existing solar installations or can be added as standalone units depending on your setup and energy goals. Installation involves connecting the battery to your electrical panel, configuring which circuits receive backup power, and integrating the system with your inverter so energy flows correctly during outages and normal operation. These systems are designed for safe integration with home electrical systems and provide reliable performance during periods of grid instability.

How Battery Storage Changes Your Energy Use

Installation begins with assessing your electrical panel, determining which circuits should receive backup power, and selecting a battery size that matches your household needs in Campbell. The battery is mounted indoors or outdoors depending on the model, and wiring connects it to your inverter and main panel. A control system monitors charge levels, grid status, and energy flow so the battery activates automatically during outages.

After installation, you will notice that your refrigerator, lights, and other selected circuits stay powered during an outage instead of going dark. If you have solar panels, the battery stores excess daytime production and releases it during evening hours, reducing the amount of energy you pull from the grid when rates are higher. You can monitor battery charge levels and usage through a connected app or display panel.

The system does not power your entire home unless it is sized and configured to do so, and heavy-draw appliances like electric heating or air conditioning may not run on battery alone. The installation includes testing, safety checks, and written documentation on system capacity and supported circuits.

Common Questions About Battery Backup

Homeowners often want to know how long the battery lasts during an outage, what it can power, and whether it works without solar panels.

How long will the battery keep my home running during an outage?
Runtime depends on battery size and what you are powering. A typical home battery in Campbell can run essential circuits like refrigeration, lighting, and internet for several hours to a full day depending on usage.
Can I install a battery without solar panels?
Yes. The battery charges from the grid and provides backup power during outages. Adding solar later allows the battery to store daytime production instead of relying entirely on utility power.
What happens when the battery is full?
Excess solar production is sent to the grid if your system is connected and configured for net metering. The battery only stores energy up to its capacity, and charging stops once it reaches full charge.
How do I know which circuits are backed up?
During installation, specific circuits are selected and labeled based on your priorities. You receive a written list showing which outlets, lights, and appliances stay powered during an outage.
When does a battery system make sense?
Battery storage is useful if you experience regular outages, want to reduce grid dependence, or need backup power for medical equipment or home offices. Growing grid strain in parts of California has increased demand for home energy storage.

If you want to maintain power during outages or manage how your home uses energy throughout the day in Campbell, Shadowfax Roofing & Solar can help you choose and install a battery system that fits your electrical setup and daily needs. Learn more about battery storage by reaching out today.
