Home Battery Backup Systems in Benbrook

What a Battery Backup System Does in Your Home

A battery system has three working parts: the battery modules, an inverter that turns stored DC power into the 120/240-volt AC your home uses, and a transfer device that disconnects your home from the utility during an outage so power cannot backfeed onto the lines. Some systems carry the entire panel. Others power a smaller subpanel that holds just the circuits you pick, such as the refrigerator, furnace blower, Wi-Fi and a few lights.

The battery is only as reliable as the panel and wiring it connects to, and that matters most in older houses. We regularly open panels with brittle breakers, two wires crammed under one lug, or an addition that was tied in by a previous owner without a permit. A battery that switches load onto a loose neutral or an overloaded bus will expose those problems fast, so we find them before the install, not after.

The work is done under our Master Electrical License by insured electricians, and the company is a licensed electrical contractor, TECL 36609.

What Our Battery Backup Installation Includes

Outage load list and surge math

Together we decide which appliances matter when the grid is down, then total their running watts and their startup surge. Motors are the tricky part: a central AC compressor can pull several times its normal current for the first second, and that spike sets the inverter size more than anything else.

Panel and service check

We inspect the main panel, breakers, bus bars and grounding before anything gets mounted. If we find an outdated or failing panel, we explain it and price the fix separately so you can see each part of the job.

Critical-loads subpanel, if needed

For partial backup we relocate the chosen circuits to a new subpanel fed by the battery. We label every breaker so you know exactly what stays on.

Mounting and placement

Batteries and inverters need clearances, a solid wall and protection from heat. We place them on a garage wall or an outdoor-rated location that keeps them within the manufacturer's temperature limits.

Permits and utility paperwork

We file for the permit, meet the inspector when the jurisdiction calls for a visit, and send any notice the utility needs before the system is energized.

Commissioning and walkthrough

We simulate an outage, confirm the transfer, and show you the app or display so you can read charge level and load.

Signs a Battery Backup System Makes Sense for You

• Outages keep costing you food or work

  Summer thunderstorms and winter ice storms knock power out across North Texas. If you have thrown out a freezer's worth of food or lost a workday, stored power pays off quickly.

• Someone relies on powered medical equipment

  Oxygen concentrators, CPAP machines and powered beds need a steady supply. A battery switches over in a fraction of a second, so equipment usually keeps running without a reset.

• A generator is not a good fit

  Some homeowners don't want engine noise, fuel storage or the exhaust clearances a standby unit needs. A battery runs silently and can sit in a garage. If you'd rather have a generator, see our Generator Installation page.

• Your panel is already due for work

  If you are planning a panel upgrade or an EV charger, adding battery backup at the same time can share the same panel work and permit visit.

• Lights flicker or breakers trip under load

  These point to a weak connection or an undersized circuit. They need fixing before a battery is added, and we check for them during the visit.

How a Battery Backup Job Runs

1. 1

   Service visit and load review

   We walk your home, open the panel, test voltage and look at the grounding and bonding. You tell us what has to run during an outage and for how long.

2. 2

   Written scope

   You get a line-item scope showing battery capacity, inverter size, whole-home or critical-loads setup, and any panel or wiring corrections. Nothing is ordered until you approve it.

3. 3

   Installation day

   Most installs take one to two days. Power is off only while we work in the panel, and we tell you beforehand so you can plan around it.

4. 4

   Inspection and handoff

   After the inspector signs off, we run a live transfer test with you watching and explain how the battery recharges once grid power returns.

What Moves the Cost of Battery Backup

Battery systems vary widely, so we price each one after seeing your panel and hearing what you want backed up. The estimate separates equipment, labor, and any corrections the existing wiring needs, so you can see where the money goes.

Storage capacity

Capacity is measured in kilowatt-hours. Running a fridge and lights overnight needs far less than carrying central air through an afternoon, and more modules mean more cost.

Whole-home or critical loads

Whole-home backup needs a larger inverter and transfer equipment rated for your full service. A critical-loads subpanel keeps equipment smaller but adds circuit relocation labor.

Condition of the existing panel

An outdated, overloaded or damaged panel may need replacement or repair before a battery can be connected safely. This is the most common surprise in older homes, which is why we check first.

Distance from the panel

Mounting the battery and inverter right next to the panel keeps conductors short. Putting them on a far garage wall or outdoors means longer wire runs, more conduit and extra wall penetrations, and each of those adds labor.
