Home battery backup for Katy homeowners
Katy is one of the fastest-growing suburbs in the Houston metro. New neighborhoods mean modern homes, but the grid infrastructure they connect to is the same CenterPoint network that has struggled through multiple major outages. Eos Backup and Battery installs battery systems that protect your home automatically.
New homes, same grid vulnerabilities
Katy has grown dramatically over the past decade. Subdivisions like Cinco Ranch, Grand Lakes, and LaCenterra continue to expand westward. Many homes are relatively new, which means updated electrical panels, modern wiring, and smart home systems. But all of them connect to the same ERCOT grid and the same CenterPoint distribution network that has failed during hurricanes, winter storms, and summer heat events.
After Hurricane Beryl in 2024, Katy homeowners were among the hundreds of thousands who waited days for power to return. A home battery would have meant the difference between a normal week and a displaced family.
The good news is that modern Katy homes are ideal candidates for battery installation. Standard 200-amp panels, two-car garages with available wall space, and single-family construction make for clean, efficient installs.

Common questions from Katy homeowners
Do you serve all Katy subdivisions, including the newer ones west of 99?
Yes. We install throughout Katy including the fast-growing communities west of the Grand Parkway, such as Cane Island, Jordan Ranch, and Elyson. These newer subdivisions are well-suited for battery installation thanks to modern panels and accessible garage layouts.
How does Fort Bend County permitting work for Katy battery installations?
Katy spans both Harris and Fort Bend counties depending on the specific address. Our team determines the correct jurisdiction for your property and handles all permitting, whether that is through the City of Katy, Harris County, or Fort Bend County. We also manage the CenterPoint interconnection notification required for all battery installations in their territory.
My Katy home has a large AC unit. Can a battery system handle it?
Yes. The Sigenergy system we install delivers 17.1 kW of peak surge capacity from a single inverter, which is enough to start a 3-ton central AC compressor without stacking units. Many competing systems require two inverters to achieve the same result. If your home has multiple large AC zones, we size the system during the site assessment to ensure it handles your specific equipment.
How long does installation take in Katy?
The physical installation takes one to two days. Permitting adds two to four weeks depending on the jurisdiction. Once permits are approved, our team schedules the installation around your availability and typically completes it in a single visit. We let you know exactly what to expect at each stage before we begin.
