Driving The Evolution Of Energy Storage


Franklin Whole Home brings energy freedom to homeowners nationwide

Energy storage is powering up in the U.S.

During Q3 2021, the country brought on 3,515 MWh of storage, breaking records as the strongest quarter ever. And while the residential segment has struggled with equipment constraints, we’re seeing a rebound with new manufacturers expanding the range of options. The story is not glum. The home storage market is expected to surpass $1 billion annually this year and grow to $2.5 billion per year by 2026[1].

So, what can residential storage companies do to advance these trends? More importantly, what is missing from today’s equation that will transition the market from early adoption to storage as a standard expectation for all solar customers?

At Franklin Whole Home, we believe the industry hasn’t focused on integrating energy storage into people’s homes and lives. We’ve done well generating, storing, and exporting energy. But when it comes to optimizing storage, we need to give homeowners more control. Our goal is to power today’s safe and reliable back-up into something more — converting energy security into energy freedom.

That’s an audacious goal. How do we get there?

As a new entrant to the U.S. residential storage market, we gave ourselves a few guiding tenets to help evolve the relationship people have with their home’s power:

Design for user’s needs tomorrow, not today

We put together the brightest minds in storage and power electronics to design a system that meets homeowners’ future needs today. This approach drives everything we do with an eye toward tapping into the full potential of residential storage. Many boast whole-home systems; few deliver on this promise. We want to safeguard the entire home with a breakthrough design that offers a powerful, smart, and flexible solution — all while keeping installation fast and easy.

The Franklin Home Power system fuses a robust duo: The aPower battery with the highest AC capacity on the market, alongside the aGate with the industry’s most intelligent controls. The aPower lithium iron phosphate battery and aGate smart control system work in concert to provide uniquely advanced storage. To ensure confidence, we back our fully-certified system with a 12-year warranty, two years more than the industry’s standard.

Franklin Home Power System

Improve comfort

Home Power uses system integration to exceed expectations from the start. Beyond supporting a home’s main panel, FranklinWH offers a key industry first: The ability to power and control up to three additional large loads, including such things as HVAC, pool heating, and electric vehicle charging. With the capability to scale up to 15 units for a total of 204 kWh, we deliver more to power people’s home and life.

Offer flexibility

We play well with everyone in the solar sandbox. Uniquely compatible with any PV inverter technology, aPower can connect easily to existing solar systems without upgrades or customization.

Get smarter

FranklinWH uses built-in adaptive learning algorithms for smart storage and maximum home comfort. This technology allows our cloud-based control system to manage the most complex load scenarios, optimizing charge to secure and protect critical appliances while keeping loads safe and balanced. Our smart, user-friendly app alerts homeowners to modify their energy use when needed, or take advantage of time-of-use rates.


We didn’t just design for the homeowner; we optimized for the installer too.  Our one-step “roll-and-hang” design is pre-assembled for fast, easy, and reliable installation. Because aPower does not require upgrades to the solar system’s electrical panel, there’s no need to file for new permits, saving two to three months and up to $5,000 in fees. With FranklinWH, contractors can leverage advanced monitoring to pinpoint and resolve failures remotely, limiting truck rolls and service calls and freeing up time for more profitable opportunities.

Create potential

The real key to our innovation is a unique combination of capacity and control. Our system gives homeowners more power to enjoy the extra things they want and the ability to optimize how that power is used. Although some associate “going green” with minimizing energy consumption, with FranklinWH users can power up the AC, heat the pool, and run high-capacity appliances while keeping electrons flowing continuously. And that’s all while cutting their energy bill, taking advantage of time-of-use rates, and selling excess solar production to the local utility.

Eco-conscious living doesn’t require sacrifice. In fact, it can be life-improving. We want to help people power their life’s full potential to achieve “Energy Freedom” on their own terms.
