Prices cover the West Palm Beach metro and assume one 13.5 kWh battery mounted on a garage or outside wall. Older homes in Riviera Beach & Lake Worth more often need panel work.
Home battery prices across West Palm Beach
Same battery, four price bands. The spread comes from panels, wall space and access: tighter and older in Downtown West Palm & Northwood, easier in Wellington, Jupiter & Boca Raton.
Downtown West Palm & Northwood
- Installed
- $11,550–$18,300 installed
- Typical job
- $12,550–$21,750 / one battery + whole-home backup
Older buildings, tight utility rooms and slower permit reviews. Batteries often end up on an outside wall, and condo or HOA approval can add weeks.
Riviera Beach & Lake Worth
- Installed
- $11,150–$17,600 installed
- Typical job
- $12,100–$20,900 / one battery + whole-home backup
Mixed older housing. Many homes need a subpanel for partial backup; the battery price is standard but the electrical work varies.
Boynton Beach & Delray
- Installed
- $10,700–$16,750 installed
- Typical job
- $11,650–$19,900 / one battery + whole-home backup
Standard pricing for the metro. Most homes have room on a garage or outside wall, and the install is usually one day.
Wellington, Jupiter & Boca Raton
- Installed
- $10,700–$17,250 installed
- Typical job
- $11,650–$20,500 / one battery + whole-home backup
Newer homes, attached garages and room for two batteries. The battery price is standard; the second unit is where the bill grows.
Real home battery jobs in West Palm Beach
Here's what common home battery jobs cost in West Palm Beach 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 $10,700–$17,250 installed; moving those circuits to a critical-loads subpanel adds $370–$1,650.
Whole-home backup: one battery + gateway
A whole-home gateway or transfer switch ($930–$3,250) 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 $11,200–$14,200 for a straightforward job; older inverters or a full panel push it toward $18,200.
Older home: battery + panel upgrade
Many 100-amp panels have no room for a battery. Going to 200 amps adds $1,400–$4,200 in West Palm Beach, and doing it with the battery means one permit and one inspection.
How much does a home battery cost in West Palm Beach?
Between $10,700 and $17,250 for one 13.5 kWh battery, installed, and most West Palm Beach homeowners pay close to $13,750. Three things set the number: how much of the house you back up, whether the panel needs work, and the brand. Partial backup on a good 200-amp panel lands near the low end; whole-home backup with a gateway and a panel upgrade can pass $18,950.
There is no federal credit to take off these numbers any more. What can still cut the bill in West Palm Beach is a utility or state battery program, a second bid, and not buying more battery than you need. Two batteries ($15,400–$31,700) is more than many homes need. Figures re-verified against 57 sources in November 2026.
Home battery prices in West Palm Beach (2026): the lines on a quote
One battery is $10,700–$17,250 installed, whole-home backup adds $930–$3,250, and a panel upgrade adds $1,400–$4,200.
| Line on the quote | Low | Typical | High |
|---|---|---|---|
| Tesla Powerwall 3 (13.5 kWh), installed | $10,700 | $13,750 | $17,250 |
| Expansion unit, added at install | $4,750 | $6,200 | $7,600 |
| Whole-home backup gateway | $930 | $1,700 | $3,250 |
| Critical-loads subpanel | $370 | $930 | $1,650 |
| Main panel upgrade (100A to 200A) | $1,400 | $2,350 | $4,200 |
| Permit and utility fees | $140 | $430 | $970 |
| Battery service visit | $140 | $330 | $750 |
| Standby generator, 20–24 kW (comparison) | $8,050 | $10,900 | $15,150 |
The battery is the biggest line, but it is not where West Palm Beach quotes differ most. Compare the gateway, panel and permit lines; one bid may include all three and another none.
What moves a home battery quote in West Palm Beach:
- 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 $1,400–$4,200 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–$970 in fees, plus the wait for permission to operate.
Ask every West Palm Beach 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 West Palm Beach by Backup Level
Essentials backup on one battery is $10,700–$17,250, whole-home backup with a gateway is $11,650–$20,500, and two batteries for a larger home are $15,400–$31,700, before any utility incentive.
Worked example: a West Palm Beach home with a 200-amp panel and a garage wall next to it gets one Powerwall 3 at $13,750 plus a whole-home gateway at $1,700: $15,450. The same house with a 100-amp panel adds an upgrade at $2,350, for $17,800.
A larger home that wants central AC on backup usually needs two batteries ($21,450 typical) plus the gateway, about $23,150. For comparison, a 20–24 kW standby generator runs $8,050–$15,150 installed in West Palm Beach, plus fuel.

Battery vs installation: where a West Palm Beach quote goes
The battery itself is about $8,200–$10,000 for a Powerwall 3 anywhere in the US. On a $13,750 West Palm Beach job that leaves roughly $4,650 for labor, wiring, the backup switch or gateway, permits and the utility paperwork.
That is why West Palm Beach bids for the same battery can sit $6,550 apart. One installer's $13,750 may include a whole-home gateway and permit fees; another's $12,650 may not. Line up the items before you compare totals.
What's included in a West Palm Beach 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 — $930–$3,250 if you want the whole panel backed up
- Panel upgrade — $1,400–$4,200 to go from 100 to 200 amps
- Critical-loads subpanel — $370–$1,650 for partial backup on older panels
- Permit and utility fees — $140–$970, 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
West Palm Beach is a mid-size market for home batteries. 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 $10,700 or $17,250.
How much of the house you back up
Partial backup on one battery is $10,700–$17,250. Whole-home backup adds a gateway ($930–$3,250) 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 $1,400–$4,200 in West Palm Beach; a critical-loads subpanel adds $370–$1,650.
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 $5,650–$8,450 per 5 kWh unit, a Powerwall 3 $10,700–$17,250 for 13.5 kWh, and a FranklinWH aPower 2 $13,600–$21,600 for 15 kWh.
Solar or no solar
A battery added to existing solar is $11,200–$18,200; a grid-charged battery with no solar is $10,700–$17,250. A battery installed with new solar shares one permit and one crew.
Permits and the utility in West Palm Beach
Expect $140–$970 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. West Palm Beach quotes for one 13.5 kWh battery run $10,700–$17,250; a second bid is the fastest way to find the padding.
- Back up the essentials, not the whole house.A critical-loads subpanel ($370–$1,650) keeps one battery on the circuits that matter. A second battery costs $8,500–$11,800.
- 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 $4,750–$7,600. 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 ($1,400–$4,200) 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 West Palm Beach 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

What permits does a home battery need in West Palm Beach?
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–$970. 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–$750 once the warranty is over.
