Residential Battery Storage Systems for Reliable Backup Power
Protect your home from unexpected outages with professionally installed battery storage systems designed to provide reliable backup power, greater energy independence, and long-term peace of mind.
Battery storage gives homeowners greater control over how and when they use electricity. Whether paired with a new solar energy system or added to an existing one, a home battery stores excess energy for use when it's needed most. During a power outage, your battery can automatically provide backup power to keep essential appliances and devices running. Beyond emergency preparedness, battery storage also helps homeowners make better use of the energy they produce while adding resilience and flexibility to their home's energy system.

Every home has different energy needs, which is why every battery storage system should be designed with your goals in mind.

Frequently Asked Questions About Residential Battery Storage
How does residential battery storage work?
Residential battery storage systems store excess electricity generated by your solar panels or the electrical grid for later use. When your home needs additional power—such as during a utility outage or periods of high energy demand—the battery automatically supplies electricity to your home based on its configuration.
Can I add a battery to my existing solar system?
In many cases, yes. Many homeowners choose to add battery storage to an existing solar system to increase energy independence and provide backup power during outages. Earthlight can evaluate your current solar installation and recommend compatible battery storage options based on your home's energy needs.
What can a home battery power during an outage?
The amount of backup power depends on the size of your battery system and your home's energy usage. Many homeowners choose to back up essential loads such as refrigeration, lighting, internet equipment, medical devices, and select appliances. Larger battery systems may be able to power additional circuits or support more of your home.
Which battery systems does Earthlight install?
Earthlight installs premium residential battery storage solutions, including Tesla Powerwall and FranklinWH systems. Our team will help you compare available options and recommend the battery solution that best fits your home's energy goals, backup needs, and existing solar system.
Is residential battery storage worth it?
For many homeowners, battery storage provides valuable peace of mind by supplying backup power during outages while increasing energy independence. When paired with solar, battery storage also allows you to use more of the energy your system generates instead of relying solely on the utility grid. The right solution depends on your home's energy usage, backup priorities, and long-term goals.
