Home battery backup in Houston, TX
Hurricane-season power that keeps the whole house running.
Home battery backup across greater Houston, sized around the loads your household actually needs when the power is out for days rather than hours.
Why Houston homes add backup
What a battery actually does during a Houston outage
Houston outages are different from the rest of Texas. Hurricane and derecho damage takes down distribution infrastructure over a wide area, and restoration is measured in days. Heat and humidity turn a long outage into a habitability problem fast, and portable generators become scarce, loud and dangerous exactly when everyone needs one.
A permanently installed battery starts automatically, runs silently inside or on a garage wall, produces no carbon monoxide, and needs no fuel runs. For many Houston homeowners that is the entire argument — not savings, but not standing in a gas line with a red can.
We work across Harris, Fort Bend and Montgomery counties: Katy, Cypress, Sugar Land, The Woodlands, Pearland, Kingwood, League City and Spring, plus the inner loop. Coastal humidity and flood history matter for equipment placement, so we look at mounting height and location during the site review.
Multi-day hurricane outages
Wind events knock out feeders across whole neighborhoods. A whole-home system carries the house through the first days, and recharges from solar if you have it.
Heat and humidity
Without power, a closed Houston house heats up quickly. Backing up fans, a window or mini-split unit, and refrigeration keeps the home usable.
No fuel, no fumes
Unlike a portable generator, a battery needs no gasoline, runs silently, and can sit safely on a garage wall. Nothing to store, nothing to refill mid-storm.
Flood-aware placement
In flood-history neighborhoods we mount equipment high and clear of known water lines, and we say so in the written scope.
With solar or without
Both work. The difference is how the battery recharges.
Compatibility depends on your existing equipment, which we confirm before we propose a design.
Homes with existing solar
Grid-tied solar shuts down during an outage for safety, so panels alone leave you dark. Adding storage lets the array keep the home running and recharge the battery during a multi-day outage. Whether the battery pairs directly with your inverter or needs an AC-coupled setup depends on the inverter make and model, so send it with your quote request.
Homes without solar
You do not need panels to get backup. The battery charges from the grid and discharges when the grid fails. Capacity is finite until power returns, so sizing and the circuit list matter more here. Many homeowners install a battery first and add solar later.
Equipment
Batteries we install
FranklinWH aPower 2
Our primary system. We are a certified FranklinWH installer, and the aPower 2 works with existing solar or on its own, sized so the home keeps running through an outage.
Other major battery brands
We also install other leading home battery brands on request. If you already have a preference, tell us in the quote form and we will confirm whether it fits your panel, your inverter and your goals.
Honest equipment advice
If your home is better served by a different product, a different configuration, or no battery at all, we will say so in writing rather than sell you something that will not do what you want.

FAQ
Battery questions from Houston homeowners
How many days of backup will I get during a Houston hurricane outage?+
That depends on your battery capacity and how much the household runs. A single battery typically spans roughly a day of careful use, and recharges the next day if you have solar. Without solar, capacity is finite until grid power returns. We size the system around your real usage instead of quoting a headline number.
Is a battery better than a standby generator in Houston?+
They solve the problem differently. A gas standby generator can run indefinitely with fuel supply but needs maintenance, produces noise and exhaust, and requires a gas line. A battery is silent, maintenance-light and instant, but limited by stored capacity unless paired with solar. Some homeowners install both. We will tell you plainly if a battery is not the right fit for your situation.
Can the battery be installed outdoors in Houston humidity?+
Many systems are rated for outdoor installation, but shaded, protected placement extends equipment life in Gulf Coast heat and humidity. We recommend the best location for your specific home during the site review.
Do you serve Katy, Sugar Land and The Woodlands?+
Yes. We cover greater Houston including Harris, Fort Bend and Montgomery counties. Enter your address in the quote form and we will confirm coverage right away.
