Back up your essentials—or your entire home—with the advanced FranklinWH energy storage system. Gain peace of mind during outages, maximize your solar savings, and take control over your energy future. Find out how a Franklin battery can work for you.
The FranklinWH Battery empowers you to stay comfortable, connected, and in control—even when the grid goes dark. Whether you’re feeling the burden of rising utility rates or looking for greater energy independence, FranklinWH’s advanced battery technology ensures dependable home backup and smarter energy use.
At the heart of this system lies the aPower 2 battery, a robust energy storage unit engineered for top-notch performance and adaptability. It seamlessly integrates with any solar inverter, making it ideal for both established and new solar-powered homes. With professional installation from StraightUp Solar—your trusted local solar partner in Missouri and Illinois—you can be confident that your battery system is built to last and ready when you need it.
FranklinWH stands out not just for power and reliability—but also its capacity to simplify and streamline your entire home energy system.
At the center of it all is the aGate, which can intelligently manage the interaction between solar, battery, utility grid, generator, and EV charging. This essentially turns your home into its own self-sustaining microgrid.
FranklinWH’s Smart Circuits offer added flexibility by giving you targeted control over specific high-power appliances. Whether you’re prioritizing a well pump during a blackout or running your EV charger during low-rate times, you can automate these decisions through the FranklinWH App. The system’s 280-amp busbar and built-in energy management features also help many homeowners avoid expensive main panel upgrades, saving you time and money on installation.
When the power goes out, FranklinWH keeps your home running. The system’s aGate energy controller switches effortlessly from grid power to backup power, keeping essential appliances like your refrigerator, internet router, and lights on without interruption. With a continuous power output of 10kW and the capacity to power up large appliances like a 5-ton air conditioner, the Franklin Battery surpasses basic backup solutions.
Constructed with lithium iron phosphate technology and engineered to endure harsh conditions, the FranklinWH Battery boasts a weather resilience rating from -4°F to 130°F. Backed by a 15-year warranty and long battery lifespan, you’ll have a system that’s as dependable as it is powerful. In the Midwest, we install the aPower 2 indoors to guarantee optimal performance through cold Illinois and Missouri winters.
One powerful feature that sets the Franklin Battery apart is its intelligent energy management. The FranklinWH App provides real-time insights into your energy consumption and gives you full control over how and when your battery discharges. Schedule high-power appliances to run during off-peak hours or manually prioritize loads in the event of an outage.
Storm Hedge automatically preps your battery when severe weather is on the horizon and comes standard with the aPower 2. When a National Weather Service alert is issued, the system charges to full capacity to make sure you’re ready for possible blackouts. Coupled with Smart Circuits that can manage individual appliances, FranklinWH offers smarter, more responsive energy backup.
The aPower 2 is designed for flexibility, both in its structure and integration with your home energy system. The Franklin battery is AC-coupled and compatible with all solar inverters.
The battery itself can handle up to 10,000 full cycles and up to 60 megawatt-hours of total energy over its lifespan. You have the flexibility to scale your system as your needs grow—up to 225 kWh of storage with 15 aPower units connected to a single aGate. With high-throughput second-generation grid-scale cells, FranklinWH retains 70% of its capacity after 15 years, delivering long-term value for years to come.
The Franklin aPower 2 is a high-capacity battery built to deliver strong, reliable backup power for the most rigorous backup needs in a compact form. It’s capable of powering your essential appliances during an outage, while also helping manage your peak energy usage and reduce your reliance on the grid.
With the FranklinWH App, managing your energy is as easy as checking your phone. From the app, you can monitor your battery’s charge and discharge in real time, adjust settings to match peak utility rates, and even respond to storms with the tap of a button. The app integrates seamlessly with Smart Circuits to give you full control over specific appliances. Get the most from every kilowatt-hour stored in your battery.
Whether you’re home or away, you’ll know exactly how your system is performing—and how much you’re saving.
