Full-Home Battery Backup in Florida: Start With the Battery
Most solar companies still lead with panels. PowerSol USA leads with the battery.
New home battery systems include hybrid inverters. The battery is the brain and the backup. Solar is the charger that keeps that battery — and your home — fed when the sun is up. In Florida, where storms, heat, and rising grid pressure are part of life, that order matters.
We are a Tampa-based, BBB A+ rated, customer-first installer serving much of Florida from Tampa Bay through Orlando, the Space Coast, Port St. Lucie, Naples, and north toward Ocala/Gainesville. We do not serve Miami-Dade, Broward, or the Panhandle.
We rarely install solar-only. Our default recommendation is battery-first, full-home backup, with solar sized to recharge and run the house by day.
Quick answer
- Battery first: hybrid inverter manages backup; solar charges it and powers the home by day.
- Full-home: most customers want the whole house.
- Runtime: nights draw the battery; days run the home and recharge it.
- Approximate cost: about $30K for ~10 kW solar + ~30 kWh battery; about $25K for ~10 kW solar-only. Confirm before purchase.
How we size Florida backup (think ~14 hours of night)
We commonly design around about 14 hours of nighttime autonomy for planned loads, then let daytime solar take over and refill.
Must-haves
- Lights
- Refrigerator
- Everyday outlets for phones, medical devices, Wi-Fi, and basics
Nice-to-have
- Air conditioning for living areas or most zones
Usually not critical
- Pool pump — nice when power allows, but not the reason we size the system
PowerSol’s aim: full-home backup. Critical-load-only is available when electrical reality or budget demands it, but most customers want the whole house.
Starting the A/C
Many Gen 2 / Gen 3 class battery systems offer on the order of ~200A pass-through. We plan the electrical path so the compressor is a designed load, not a surprise.
Product stack we recommend
- Anker, including tri-fuel generator option or EP Cube 2 paths, is often strong value.
- FranklinWH and Fortress are strong residential peers.
- Tesla fits when FEOC-compliant or when project needs line up.
We match the home, not a single logo. No fake “#1 in Florida” crown.
Approximate pricing (orientation only; confirm before purchase)
- About $30,000 — roughly 10 kW solar + about 30 kWh battery
- About $25,000 — roughly 10 kW solar-only
Solar-only looks cheaper on paper but leaves you without the backup architecture many Florida families want. For most new residential systems in 2026, the old 30% federal Residential Clean Energy Credit (§25D) does not apply to expenditures after December 31, 2025. Ask your tax advisor about any carryforward; we do not invent rebates.
How long will the battery last?
At night the home draws from the battery. By day solar runs the house and recharges it. Runtime is measured in as many days as the sun and your system allow, not one disposable charge.
Real Florida story: Apollo Beach / Tampa area
With permission to share the experience, a homeowner’s uncle in the Apollo Beach / Tampa area had about 17 kW of solar and two FranklinWH batteries installed before the last hurricane. The surrounding community lost utility power for about eight days; their home held A/C around 70°F, and they said they did not notice when the grid went out or came back.
Stay on Duke, TECO, FPL, OUC without the anxiety
You stay interconnected with your utility. Outages stop owning your week, and many months feel like you are mostly living on your own generation and storage. Customer-first means we show you the math; BBB A+ means we will not scare you into a signature.
What working with PowerSol looks like
- Goals conversation — backup first, then solar as charger, EV if needed
- Load review — must-haves, A/C zones, and what can wait
- Battery and hybrid design, then solar sized to recharge
- Permitting, utility interconnection, installation, inspection, and support

FAQ
Do you ever install solar without a battery?
Rarely. Our default is battery-first, and we explain what panels-only gives up in an outage.
Full-home backup vs critical loads?
Full-home for most families. Critical-load-only is the exception.
Can the system run my A/C?
That is a design requirement for many customers. Pass-through capacity and load planning matter; we engineer it.
How long will it last in a hurricane outage?
Nights on battery, days on solar with recharge — for as many productive sun days as you get.
Ready to stop worrying about the next outage?
Ask for a battery-first home energy design sized for nighttime autonomy, lights, fridge, outlets, and the A/C you actually want.
