Home battery backup · Tampa Bay

When the grid goes down in a storm, the house stays on. Quietly.

Fused installs and services FOX ESS, Tesla Powerwall 3, FranklinWH and Enphase batteries under its own electrical license, with or without solar. We installed standby generators for eighteen years before batteries got good enough to replace them. For a new solar-plus-battery home we now recommend FOX ESS, and we'll tell you plainly when another brand, or a generator, is the better fit.

  • FOX ESS for new solar and battery together: 19.85 kWh, generator input and smart circuits built in
  • FranklinWH for adding a battery to solar you already have; Tesla and Enphase on request
  • Whole-home backup including central AC, sized to what you need to keep running
  • Authorized FOX ESS installer; certified by Tesla, FranklinWH, Enphase and Generac Clean Energy
  • Service on any battery brand, including systems other companies installed
  • Permit, inspection, app setup and a photo report on every install

Which battery

The right battery depends on whether the solar is new or already on the roof

FOX ESS: new solar and battery togetherOur pick

PowerQ 11.4 kW hybrid inverter with a 19.85 kWh LFP battery bank stacked under it and the Fox Hub G2. Whole-home backup including AC, a wired generator input, three smart circuits that shed loads automatically, Tigo monitoring on every panel, Type 4X enclosure for salt air, 12.5-year warranty. Expandable to 27.8 kWh on the same stack.

Tesla Powerwall 3: if you want Tesla

Built-in solar inverter runs the array, 13.5 kWh and 11.5 kW per unit, stackable with Expansion units, 10-year warranty. We are Tesla-certified for install and service and still install Powerwall for customers who want it.

FranklinWH aPower: adding a battery to existing solar

Designed for AC-coupled systems, which is what an add-on battery is. Works with the inverter you already have, any brand. aPower, aPower 2 and aPower S; we install and service all of them as a certified FranklinWH installer.

Enphase homes and homes with no solar

If your roof already runs Enphase microinverters, the Enphase IQ Battery 5P (5 kWh per unit, 15-year warranty) pairs cleanly with it. No solar at all? A standalone battery charges from the grid and backs up the house; we install those too and set up the app with you before we leave. Batteries are quoted after a site review; we don't publish battery prices because the panel, wiring and backup scope change the number.

Battery vs generator

We sold generators for eighteen years. Here's why we stopped leading with them.

A standby generator sits at ground level, which in Tampa Bay means storm surge and salt water. It needs fuel, oil changes and exercise cycles, and it only does anything during an outage. A battery mounts on the wall, cycles every day on solar to cut the power bill, and takes over in an outage without a sound. For most homes the battery wins. And with FOX ESS you don't have to choose: the Fox Hub G2 has a wired generator input with two-wire auto-start, so a standby unit, or an ordinary portable generator from Home Depot or Lowe's, only runs when the battery is depleted and shuts off when the sun is back. Tesla's answer to the same problem is Powershare, which requires a Cybertruck.

Already have a battery with a problem?

Not charging, not backing up, gateway offline, app errors. We service FOX ESS, Tesla Powerwall, FranklinWH, Enphase and Generac batteries from any installer and handle warranty-covered work. Repair and diagnostics →

The electrical side

Our own electrical license, so nothing waits on a second contractor

Main panel upgrades

Older homes often need a larger main service panel before a battery or solar goes in. We do the upgrade under license EC13014750, coordinate the utility shutoff and reconnect, test every circuit and walk you through the new panel.

Smart circuits and SPAN panels

The Fox Hub G2 includes three smart circuits, which covers most homes' load shedding without another box. When you want control of every circuit from your phone, a SPAN panel does that; we install SPAN with solar and battery systems and as a standalone panel upgrade.

EV chargers

Tesla Wall Connector and Universal Wall Connector, installed with a permit and tested with your car before we leave. One-year workmanship warranty.

Questions

Home batteries in Tampa Bay, answered plainly

Which home battery does Fused recommend?

For a new solar-plus-battery home, FOX ESS: the PowerQ 11.4 kW hybrid inverter with a 19.85 kWh battery bank and the Fox Hub G2. It carries about 47% more storage than a single Powerwall 3, has a wired generator input and three smart circuits built into the Hub, panel-level monitoring on every solar panel, and a 12.5-year warranty. If you already have solar and want to add a battery, FranklinWH aPower is usually the right fit. If you want Tesla or Enphase, we install and service those too.

Can a home battery run my air conditioning during an outage?

Yes. The FOX ESS package (11.4 kW) and a Tesla Powerwall 3 (11.5 kW) can both carry a whole home including central AC. Running the AC drains the battery faster, so the system is sized around what you want to keep running and for how long, and solar recharges it during the day. FOX ESS adds three smart circuits that shed loads you choose, such as a pool pump or second AC, when the battery runs low.

Which battery is best if I already have solar?

FranklinWH aPower. It is AC-coupled, which is what an add-on battery is, so it works with the inverter you already have from any brand. We install and service aPower, aPower 2 and aPower S. If your existing system is Enphase microinverters, the Enphase IQ Battery 5P is the other clean fit.

Is a battery better than a standby generator in Florida?

For most homes, yes. A standby generator sits at ground level, which in Tampa Bay means storm surge and salt water; it needs fuel, oil changes and exercise cycles, and it only does anything during an outage. A battery mounts on the wall, cycles every day on solar to cut the power bill, and takes over in an outage without a sound. With FOX ESS you can also wire a generator, even a portable one, into the Hub so it only runs when the battery is depleted.

Where does the battery go?

Outside the home on an exterior wall, like all our battery installs. The FOX ESS PowerQ and battery stack carry a Type 4X enclosure rating, the NEMA class with corrosion resistance, and are rated from -13°F to 131°F. A garage install is possible but Florida code adds curbs, extra emergency stops and fire protection, which usually isn't worth the cost.

Do you service batteries you didn't install?

Yes. We service FOX ESS, Tesla Powerwall, FranklinWH, Enphase and Generac batteries from any installer and handle warranty-covered work. Not charging, not backing up, gateway offline, app errors: start with our $395 diagnostic.

Does the annual maintenance plan cover the battery?

The maintenance visit inspects and documents the whole system, including the battery's status and any error codes in its app, and the report notes anything that needs attention. Corrective work on a battery is quoted separately, and warranty-covered repairs go through the manufacturer with us as the installer.
