FranklinWH Battery Storage Installation
When homeowners ask us what separates a good home battery from a great one, the answer usually comes down to three things: how much it can power, how long it lasts, and how confidently the manufacturer stands behind it. The FranklinWH aPower 2 leads the residential storage market on all three counts—and Sea Bright Solar is proud to install it for homeowners across New Jersey, New York, and Southern California. With over 20 years of solar installation experience and thousands of completed projects behind us, we know which products deliver and which ones disappoint. FranklinWH delivers.
What Is the FranklinWH aPower 2?
The FranklinWH aPower 2 is a whole-home energy storage system that sets the bar for what residential batteries should be. Each unit stores 15 kWh of usable energy and delivers 10 kW of continuous output power—enough to run a 5-ton central air conditioner, EV charger, and major appliances all at once from a single battery. That’s a level of output that most competing systems require multiple units to achieve. The aPower 2 pairs with FranklinWH’s aGate smart controller, which serves as the brain of the system—managing energy flows between your solar panels, the grid, and your home’s circuits automatically and intelligently. Need more capacity? Up to 15 aPower 2 units can be stacked per aGate, reaching 225 kWh of total storage—enough to cover large properties, small businesses, or any home with extraordinary energy demands. Everything runs on LFP battery chemistry, which offers superior thermal stability and longevity compared to older technologies, backed by a 15-year warranty covering 60MWh of guaranteed throughput—the longest warranty in the residential storage industry.
What Makes FranklinWH the Right Choice for NJ, NY, and California Homes
Choosing a home battery isn’t just about capacity on a spec sheet. It’s about whether that battery will actually protect your home when a storm knocks out power for three days, intelligently cut your bill when California’s peak-hour rates spike, and still perform at the end of a 15-year warranty. FranklinWH was engineered to answer yes to all of those questions.
Here’s what you get:
Built-In Automatic Transfer Switch — No Add-Ons Required Many competing battery systems require a separate automatic transfer switch to achieve true whole-home backup. The FranklinWH aGate includes this functionality natively. The moment grid power fails, your home switches to battery seamlessly—no third-party hardware, no delays, no manual steps.
Works With Virtually Every Solar Inverter Brand Unlike some storage systems that only work with their ecosystem, the FranklinWH aPower 2 is fully inverter agnostic. It integrates cleanly with SolarEdge, Enphase, SMA, Fronius, and virtually every other major inverter brand on the market—making it an excellent retrofit option for homes that already have solar installed.
Quiet Enough to Forget It’s There The aPower 2 uses fanless convection cooling rather than active fans. The result is whisper-quiet operation that won’t disrupt your home’s daily life, even when the battery is working hard. It’s a small detail that makes a meaningful difference in lived experience.
Smart Control That Puts You Ahead of the Rate Schedule The FranklinWH App gives you granular control over how and when your battery charges and discharges. Set time-of-use schedules to avoid peak utility rates in New Jersey, New York, and California. Manage individual Smart Circuits. Use the built-in AI voice assistant to check system status or get instant answers — hands-free. It’s energy management that works the way modern homeowners actually live.
Black Start Capability — Power Returns Even After a Full Drain If your battery is completely depleted during an extended outage and the grid is still down, most systems simply wait for it to come back. The FranklinWH aPower 2 features intelligent black start technology—when the sun rises, the system automatically uses incoming solar energy to restart and recharge the battery, restoring power to your home without any human intervention.
The Warranty That Changes the Math A 15-year warranty covering 60MWh of throughput isn’t just a marketing headline—it fundamentally changes the financial math on home battery storage. It means more time-of-use savings, longer participation in utility export and Virtual Power Plant programs, and a longer window to earn back your investment. No other major residential battery matches it.

Your FranklinWH Questions, Answered
For most homes in New Jersey, New York, and Southern California, yes. The aPower 2 delivers 10 kW of continuous output from a single unit—powerful enough to simultaneously run a 5-ton AC system, refrigerator, lighting, EV charger, and other major loads. Sea Bright Solar will conduct a full load analysis during your consultation to confirm exactly what your system needs to cover everything that matters to you.
Absolutely — and this is one of FranklinWH’s biggest strengths. The aPower 2 is compatible with virtually all mainstream solar inverter brands, so you won’t need to replace your existing equipment to add storage. Sea Bright Solar performs a full compatibility review before installation to make sure everything integrates properly.
The aPower 2’s black start technology means that even if the battery is fully depleted, it will automatically restart and begin recharging using solar power the moment the sun rises—no manual intervention is required. For homes in areas prone to extended outages, Sea Bright Solar can also design your system with additional battery units to extend your backup window significantly.
It’s the longest warranty in the residential storage market from a major manufacturer. Most competing systems offer 10 years. FranklinWH’s 15-year warranty covers 60MWh of throughput, which is equivalent to more than 10,000 full charge cycles, ensuring your battery is protected well into the 2030s and beyond.
System cost varies based on configuration and home size. Sea Bright Solar offers zero-down financing options, and FranklinWH installations, alongside solar, may qualify for the 30% federal Investment Tax Credit, plus additional state and utility incentives in NJ, NY, and CA. We’ll walk you through the full financial picture during your free consultation.
