Prices are before incentives. The federal 30% battery credit is gone for 2026 installs (it ended for expenditures after December 31, 2025), so any help now comes from your utility or state. Check your utility for a battery or demand-response program before you sign.

Real home battery jobs in Palm Bay
Here's what common home battery jobs cost in Palm Bay in 2026, installed, before incentives.
Essentials backup: one battery + critical-loads panel
Fridge, furnace fan, lights, Wi-Fi and a few outlets on one 13.5 kWh battery. The battery is $10,500–$16,900 installed; moving those circuits to a critical-loads subpanel adds $360–$1,600.
Whole-home backup: one battery + gateway
A whole-home gateway or transfer switch ($910–$3,200) lets one battery run the whole panel during an outage. Central AC or a well pump may still need a second battery to start reliably.
Bigger home: two batteries
27–30 kWh for larger homes or longer outages. A Powerwall 3 plus an expansion unit sits at the low end; two full units or two FranklinWH aPower 2s sit at the top.
Adding a battery to solar you already have
An AC-coupled battery works next to your existing inverter. Expect $10,950–$13,900 for a straightforward job; older inverters or a full panel push it toward $17,800.
Older home: battery + panel upgrade
Many 100-amp panels have no room for a battery. Going to 200 amps adds $1,350–$4,100 in Palm Bay, and doing it with the battery means one permit and one inspection.
How much does a home battery cost in Palm Bay?
$10,500–$16,900 installed, with $13,450 the typical Palm Bay price for a Powerwall 3-size battery. About $8,200–$10,000 of that is the battery, wherever you live. The rest is labor, wiring, permits and utility paperwork, and that is the part that changes from one Palm Bay installer to the next.
Adding storage at install time is the cheap way to get more of it. A Powerwall 3 expansion unit adds 13.5 kWh for $4,700–$7,500 in Palm Bay, against $8,350–$11,600 for a second full Powerwall 3. Two batteries for whole-home backup run $15,050–$31,000, re-verified against 57 sources in November 2026.

Partial vs whole-home backup in Palm Bay: the gap is the gateway ($910–$3,200) and, often, a second battery. If you only need the fridge, furnace and Wi-Fi through an outage, partial backup on one battery is the better buy.
What moves a home battery quote in Palm Bay:
- Backup level — partial backup on a backup switch is cheapest; whole-home backup adds a gateway and often a second battery.
- The panel — a full or 100-amp panel can add $1,350–$4,100 for an upgrade.
- Where it mounts — a garage or outside wall near the panel is cheapest; long wire runs and trenching add labor.
- Brand and size — a 5 kWh Enphase unit and a 15 kWh FranklinWH are very different checks.
- Permits and the utility — $140–$960 in fees, plus the wait for permission to operate.
Ask every Palm Bay installer for the same four things: the battery price, the backup equipment (switch, gateway or subpanel), the panel work, and permit and utility fees. Compare those lines, not the total. Get a quote for your battery install →
Home Battery Cost in Palm Bay by Backup Level
Essentials backup on one battery is $10,500–$16,900, whole-home backup with a gateway is $11,400–$20,100, and two batteries for a larger home are $15,050–$31,000, before any utility incentive.
Worked example: a Palm Bay home with a 200-amp panel and a garage wall next to it gets one Powerwall 3 at $13,450 plus a whole-home gateway at $1,650: $15,100. The same house with a 100-amp panel adds an upgrade at $2,300, for $17,400.
A larger home that wants central AC on backup usually needs two batteries ($20,950 typical) plus the gateway, about $22,600. For comparison, a 20–24 kW standby generator runs $7,900–$14,850 installed in Palm Bay, plus fuel.

Battery vs installation: where a Palm Bay quote goes
The battery itself is about $8,200–$10,000 for a Powerwall 3 anywhere in the US. On a $13,450 Palm Bay job that leaves roughly $4,350 for labor, wiring, the backup switch or gateway, permits and the utility paperwork.
That is why Palm Bay bids for the same battery can sit $6,400 apart. One installer's $13,450 may include a whole-home gateway and permit fees; another's $12,350 may not. Line up the items before you compare totals.
What's included in a Palm Bay battery quote (and what costs extra)
A standard quote covers the battery, mounting, wiring to your panel, a basic backup switch, commissioning and the app setup. The headline price often leaves out:
- Whole-home backup gateway — $910–$3,200 if you want the whole panel backed up
- Panel upgrade — $1,350–$4,100 to go from 100 to 200 amps
- Critical-loads subpanel — $360–$1,600 for partial backup on older panels
- Permit and utility fees — $140–$960, plus bollards or a heat alarm if the battery goes in a garage
Ask for the warranty terms in writing: years, capacity guaranteed at the end, and who services the battery locally.
Your local market
Palm Bay is a smaller market with fewer battery installers to choose from. The hardware price is national; labor, permits and how many installers compete for the job are local, and they decide whether a quote lands nearer $10,500 or $16,900.
How much of the house you back up
Partial backup on one battery is $10,500–$16,900. Whole-home backup adds a gateway ($910–$3,200) and, in bigger homes, a second battery.
Your electrical panel
A crowded or 100-amp panel is the most common surprise. Upgrading to 200 amps adds $1,350–$4,100 in Palm Bay; a critical-loads subpanel adds $360–$1,600.
Where the battery goes
Garages and outside walls are the usual spots. Model codes keep batteries out of bedrooms and living space, cap garage installs at 80 kWh, and call for impact protection where a car could hit the unit.
Brand and capacity
An Enphase IQ 5P is $5,500–$8,300 per 5 kWh unit, a Powerwall 3 $10,500–$16,900 for 13.5 kWh, and a FranklinWH aPower 2 $13,350–$21,200 for 15 kWh.
Solar or no solar
A battery added to existing solar is $10,950–$17,800; a grid-charged battery with no solar is $10,500–$16,900. A battery installed with new solar shares one permit and one crew.
Permits and the utility in Palm Bay
Expect $140–$960 in permit and interconnection fees and a wait for the utility's permission to operate if the battery ties into solar.
- Get two or three bids.Same battery, different labor lines. Palm Bay quotes for one 13.5 kWh battery run $10,500–$16,900; a second bid is the fastest way to find the padding.
- Back up the essentials, not the whole house.A critical-loads subpanel ($360–$1,600) keeps one battery on the circuits that matter. A second battery costs $8,350–$11,600.
- Ask about your utility's battery program.Programs that pay you to share the battery at peak times can return a few hundred dollars a year or more.
- Add storage at install time.An expansion unit added with the first battery is $4,700–$7,500. Coming back later means a second trip, a second permit and often a second full battery.
- Do the panel work with the battery.A 200-amp upgrade ($1,350–$4,100) done in the same job shares the permit, the inspection and the utility visit.
- Read the warranty before you pick a brand.Powerwall 3 and SolarEdge carry 10 years at 70% capacity; Enphase and FranklinWH carry 15 years. A longer warranty can be worth a higher price.
Before you pay a deposit to a Palm Bay installer, get these in writing:
- The battery brand, model and usable kWh
- Backup type: partial (backup switch or subpanel) or whole-home (gateway)
- Any panel upgrade or subpanel, priced as its own line
- Where the battery mounts, and any bollards or heat alarm the code needs
- Permit, inspection and utility interconnection fees
- Warranty: years, capacity guaranteed and who services it locally
- Monitoring app setup and any utility program enrollment
- Payment schedule, and what happens if the utility approval is delayed

Enphase IQ Battery 5P: $5,500–$8,300 per 5 kWh unit; IQ Battery 10C: $10,150–$15,650. FranklinWH aPower 2 (15 kWh): $13,350–$21,200, installed.
What permits does a home battery need in Palm Bay?
An electrical permit at minimum, often a building or fire review, and your utility's approval if the battery ties into solar or can send power to the grid. Fees run $140–$960. Garage installs may need a heat alarm and bollards.
How long does a home battery last, and what does upkeep cost?
Warranties run 10 years (Powerwall 3, SolarEdge) to 15 years (Enphase, FranklinWH), guaranteeing 60–70% capacity at the end. Upkeep is mostly app monitoring; a service visit costs $140–$730 once the warranty is over.
