FranklinWH Battery

Unlike a standalone battery, FranklinWH is engineered as a complete energy management system: the aGate controller orchestrates power across solar, battery, grid, and generator sources to deliver true whole-home backup, intelligent load management, and optimized energy use. The system is designed for homeowners who want seamless backup that covers the entire home rather than a limited set of critical circuits.

The FranklinWH platform centers on two components working together. The aPower battery is a LiFePO4 (lithium iron phosphate) energy storage unit delivering whole-home backup capacity, stackable to scale storage for larger homes and longer backup duration. The aGate is the intelligent controller — the brain of the system — managing the transition between grid and backup power, coordinating solar and generator inputs, balancing loads during outages, and enabling smart energy features like time-of-use optimization and whole-home or partial-home backup configuration.

The Trade Table carries FranklinWH Home Power systems with full manufacturer warranty coverage, pairing the aPower battery and aGate controller into complete whole-home energy storage and backup solutions.

FranklinWH | Whole-Home Energy Storage & Management with aPower Battery and aGate Controller

A FranklinWH Home Power system installs as the energy management and storage layer of a home, with the aGate controller wired between the utility connection, the home's electrical panel, the solar system, and any generator, and the aPower battery providing the stored energy. When the grid goes down, the aGate seamlessly transitions the home to backup power from the aPower battery and solar, managing loads intelligently to extend backup duration. When grid power is available, the aGate optimizes energy use — storing solar, drawing from the battery during peak-rate periods, and charging from the grid when advantageous.

The aPower battery uses LiFePO4 chemistry chosen for thermal stability, long cycle life, and safety, delivering whole-home backup capacity in a single unit and stacking to scale storage for larger homes, higher loads, or longer backup duration. Multiple aPower units combine under a single aGate controller to build the total storage capacity the home requires, making the system scalable from whole-home backup through extended off-grid-capable storage. As a stackable home battery platform, the aPower competes directly with other modular systems like the HomeGrid Stack'd battery, differentiated by FranklinWH's integrated whole-home management layer.

The aGate controller is what distinguishes FranklinWH from a simple battery. It functions as the home's energy traffic controller — managing the automatic transition to backup during outages, integrating solar production, coordinating a generator as a backup charging source for extended outages, balancing loads to prevent overload during backup, and enabling smart features like time-of-use arbitrage and whole-home versus partial-home backup configuration. The aGate also provides monitoring and control through the FranklinWH app, giving homeowners visibility into production, storage, and consumption.

FranklinWH integrates solar, battery, grid, and generator into one coordinated system, which is its core strength — many backup systems handle only battery and grid, forcing homeowners to choose between battery backup and generator backup. Paired with a hybrid inverter and solar array, or running off-grid with generator support, FranklinWH's generator integration lets the system use a fuel generator as a backup charging source during prolonged outages while the battery handles instantaneous loads and solar recharges during the day, delivering resilience that extends well beyond battery-only systems.

FranklinWH FAQs

What is FranklinWH?

FranklinWH is a whole-home energy storage and management system built around two components: the aPower battery, a LiFePO4 energy storage unit, and the aGate intelligent controller that manages power across solar, battery, grid, and generator sources. Unlike a standalone battery, FranklinWH is a complete energy management platform — the aGate coordinates whole-home backup, intelligent load management, solar integration, generator integration, and smart energy features. The system is designed to back up an entire home rather than a limited set of critical circuits, with stackable aPower batteries scaling storage to the home's needs.

What's the difference between the aPower battery and the aGate?

The aPower and aGate work together as a system. The aPower is the battery — a LiFePO4 energy storage unit that stores energy and delivers backup power, stackable to scale total capacity. The aGate is the intelligent controller, the brain of the system — it manages the automatic transition to backup during outages, coordinates solar and generator inputs, balances loads to extend backup runtime, enables time-of-use optimization, and provides monitoring and control through the FranklinWH app. You need both: the aPower stores the energy, and the aGate manages how that energy moves between solar, battery, grid, generator, and the home.

How is FranklinWH different from a Tesla Powerwall?

Both FranklinWH and Tesla Powerwall provide whole-home battery backup with solar integration, but they differ in architecture and integration. FranklinWH uses a two-component system — the aPower battery plus the dedicated aGate energy management controller — with a core emphasis on integrating a fuel generator as a backup charging source alongside solar and battery, delivering resilience for extended outages. The aGate's whole-home management and generator integration are central to FranklinWH's positioning. The right choice depends on the specific home's solar setup, backup duration goals, generator plans, and capacity needs. The Trade Table helps customers evaluate whether FranklinWH fits their backup requirements and energy goals.

Are FranklinWH systems good? (FranklinWH review)

FranklinWH is well-regarded in the home energy storage market for its whole-home energy management approach, the aGate controller's coordination of solar, battery, grid, and generator, and its LiFePO4 aPower battery chemistry. The system's generator integration is frequently cited as a differentiator, since it extends backup resilience beyond battery-only systems for prolonged outages. As with any home energy system, the right evaluation depends on matching the system to the specific application — backup goal, home size, solar setup, generator plans, and budget. The Trade Table helps customers assess whether FranklinWH's whole-home management approach fits their requirements.

How much does a FranklinWH system cost? (FranklinWH cost)

FranklinWH cost depends on the configuration — primarily the number of aPower batteries (which sets total storage capacity) plus the aGate controller, and the installation. A single-aPower system for essential whole-home backup costs less than a multi-aPower configuration for larger homes or longer backup duration. Total installed cost also includes installation by a licensed electrician, any solar or generator integration, permits, and inspection. Because pricing varies by configuration, region, and current market conditions, the Trade Table provides current pricing for the specific FranklinWH configuration that matches your home's capacity and backup needs.

How many aPower batteries do I need?

The number of aPower batteries depends on what you want to back up and for how long. A single aPower may cover essential whole-home backup for a typical outage, while larger homes, homes with significant HVAC and large appliance loads, or homes wanting extended backup duration need multiple aPower units stacked under the aGate. The calculation weighs the home's daily energy use, the loads you want to run during an outage, the desired backup duration, available solar to recharge, and whether a generator is integrated for extended outages. The Trade Table runs this sizing against your specific loads to determine the right number of aPower batteries.

Can FranklinWH integrate with a generator?

Yes — generator integration is a core feature of the FranklinWH system and one of its key differentiators. The aGate controller can coordinate a fuel generator as a backup charging source during prolonged outages, using the generator to recharge the aPower battery while the battery handles instantaneous home loads and solar recharges during daylight. This layered approach delivers resilience well beyond battery-only systems, since the generator extends backup indefinitely as long as fuel is available, while the battery provides clean, instant, silent power for everyday outage coverage. The aGate manages the coordination automatically.

How long do FranklinWH batteries last?

The FranklinWH aPower battery uses LiFePO4 chemistry rated for a long cycle life, translating to roughly 10-15+ years of service depending on cycle frequency, depth of discharge, operating temperature, and usage pattern. LiFePO4 chemistry maintains a stable thermal safety profile and holds up well over many cycles. FranklinWH backs the system with a manufacturer warranty reflecting the expected long service life of the chemistry — confirm current warranty terms (years and throughput coverage) for your specific configuration at the time of purchase. Service life is maximized by operating within recommended parameters and keeping the aGate and app firmware current.
