As more homeowners explore smarter ways to take control of their home’s energy ecosystem, battery storage systems have become a larger topic of conversation. The Franklin Whole Home Battery offers reliable backup power, advanced energy optimization, and grid interaction capabilities, making it an ideal companion for homes with or without solar power. Whether you’re preparing for outages, reducing utility costs, or working toward energy independence, this system is designed to keep your home running efficiently and sustainably. The rise in demand for artificial intelligence is putting greater strain on our grid, so now is the time to consider smart alternative options for your home.

Capabilities of the Franklin Whole Home Battery

The Franklin Whole Home Battery isn’t just a backup system, it’s a fully-integrated smart energy solution. One of the features that stand out is its ability to function with and without solar panels, giving homeowners unmatched flexibility in their energy setup. The Franklin battery can easily be integrated with solar later. For homeowners who have solar, this is a solar battery that can store extra energy produced by their system in the battery for later use.

In addition to storing power from solar, the electric grid, or an electric vehicle (optional bi-directional charging module required), the Franklin battery can send energy back to the grid, and be programmed to do so during high-rate times to maximize your savings. The battery can be programmed to use energy during non-peak hours (lower cost), and send energy back to the grid during peak hours (higher cost). This time of use programming can help reduce strain on the grid while putting money back in your pocket. It’s important to note that not all states participate in “peak shaving” or time of use programming. If you’re unsure whether your state participates, call 1-844-SUNNYMAC, and one of our team members will be happy to provide you with the answer.

Want even more control? With the bidirectional charging module, the system can interact with a compatible EV. This means your bidirectional EV battery can charge your home during outages or act as a supplemental energy source, and vice versa. It’s a future-ready feature that makes the Franklin battery a powerhouse of innovation. SunnyMac provides EV charger installation for the Franklin bi-directional component and other EV chargers.

Warranty

Franklin batteries come with a 15-year manufacturer’s warranty on its newer system — aPower two system and a 12-year warranty for its older aPower models, covering both performance and hardware. The warranty is designed to protect against manufacturing defects and ensure the system retains a certain percentage of its original capacity over the 15-year period. When installed by a certified partner like SunnyMac, you get full warranty protection and access to product support.

Our team will review your warranty details at the time of installation, so you always know what’s covered and what to expect. It’s part of our commitment to stability, sustainability, and service with integrity.
