A battery energy storage system stores electricity for later use so your home can use power from solar, the grid, or another source when it is most valuable. FranklinWH is a home battery energy storage system designed for whole-home backup, daily energy shifting, and better control over household energy use.

FranklinWH’s system combines battery storage with intelligent energy management so homeowners can keep essential loads running during outages and use stored energy when utility rates are higher.

The right number of FranklinWH batteries depends on what you want to back up, how long you want backup power to last, and whether you are pairing the system with solar. A single aPower 2 can be enough for many homes that want strong whole-home backup capability, while homes with larger HVAC loads, electric appliances, or longer outage expectations may want two or more batteries.

FranklinWH systems can scale significantly, so the best fit usually comes from matching battery count to your load profile and backup goals.

FranklinWH is positioned as a whole home battery backup solution because it is built to support large household loads and manage backup power across the home, not just a few critical circuits.

The aPower 2 is marketed for whole-home backup with a single battery in many use cases, and the system is designed to coordinate solar, stored energy, and other power sources through the FranklinWH ecosystem.

Backup duration depends on how much electricity the home uses and whether the battery is supporting only essentials or the full house. With 15 kWh of storage per aPower 2, a homeowner can get meaningful backup time for critical loads, while solar recharging or adding more batteries can extend runtime further.

Homes with air conditioning, electric heating, or larger appliance loads may need additional storage for longer whole-house battery backup.

Homeowners often consider FranklinWH because it combines strong battery capacity, high output, whole-home backup positioning, solar compatibility, and intelligent energy controls in one platform.

The aPower 2 offers 15 kWh capacity, 10 kW continuous output, scalable expansion up to 15 batteries per aGate, and integration across solar, grid, generator, and EV energy sources, making it a flexible home energy storage system for both backup and everyday energy optimization.
