Extended Warranty for Peace of Mind

One of the most notable upgrades with the aPower 2 is the warranty extension. While the aPower X came with a 10-year warranty, the aPower 2 doubles down with a 15-year warranty. This extended coverage offers homeowners greater confidence in the longevity and durability of their investment.

A longer warranty means fewer worries about unexpected repairs or performance degradation over time, ensuring that your battery system will continue to serve your home efficiently well into the future. This is especially important given that home battery systems represent a significant financial commitment.

More Storage Capacity to Power Your Home

Storage capacity is a critical factor for any home battery system, and Franklin Whole Home has increased this with the aPower 2. The previous generation offered 13.6 kWh of usable storage, but the aPower 2 boosts this to 15 kWh. This increase means you can store more energy generated from your solar panels, giving you greater independence from the grid during outages or peak demand times.

More storage translates to longer backup power availability and the ability to power more household loads without interruption. For families looking to maximize their solar energy usage, the aPower 2’s enhanced capacity is a welcome improvement.

Double the Continuous Power Output

Alongside increased storage, the aPower 2 also delivers a significant jump in continuous power output. The aPower X provided 5 kW continuous output, whereas the aPower 2 doubles this to 10 kW. This higher power output means the battery can support more appliances and larger loads simultaneously.

For example, with this upgrade, the aPower 2 can start and run a 4 or 5-ton HVAC unit on its own, whereas previously, homeowners would have needed two batteries to handle such a load. This improvement provides more flexibility and capability for powering critical home systems during power outages or peak energy periods.

Increased LRA for Starting Larger Appliances

The aPower 2 also features a larger Locked Rotor Amps (LRA) rating. LRA is a measure of the surge current needed to start motor-driven appliances such as air conditioners and refrigerators. A higher LRA means the battery can handle the initial power surge required to start larger appliances without needing additional batteries or backup systems.

This enhancement allows the aPower 2 to effectively power more demanding equipment on its own, which is a significant advantage for homeowners with larger homes or higher energy demands.

Compatibility with Older Systems and Retrofit-Friendly

A big advantage of Franklin Whole Home batteries, including the aPower 2, is their compatibility with existing solar installations. The batteries work seamlessly with older microinverters and string inverters, making them ideal for retrofits where homeowners want to upgrade their backup power without rewiring or replacing their entire solar system.

This contrasts with some competitors, such as the Tesla Powerwall 3, which often require extensive rewiring or system modifications if installed alongside existing solar setups. Franklin’s agnostic approach means the aPower 2 can be integrated smoothly, saving homeowners time, money, and hassle.

Future-Proofing with Cross-Generation Compatibility

Another standout feature is the aPower 2’s compatibility with previous generation Franklin Whole Home batteries. If you installed an aPower X last year and decide to add an aPower 2 later, the two batteries will work together seamlessly. This cross-generation compatibility ensures your system can grow and adapt over time without forcing you to replace older components.

Many other manufacturers do not offer this level of backward compatibility, so Franklin Whole Home’s approach is a major benefit for homeowners who want to future-proof their energy storage investments.

Franklin aPower 2 vs. Tesla Powerwall 3: What’s the Difference?

When considering home battery systems, many homeowners naturally compare Franklin Whole Home’s offerings with Tesla’s Powerwall series, particularly the newly released Powerwall 3. While both are high-quality products, there are important differences to understand.

AC Coupled vs. DC Coupled Systems

One of the fundamental differences is the type of coupling used in the system. Franklin Whole Home batteries, including the aPower 2, are AC coupled, while Tesla Powerwall 3 uses a DC coupled system.

AC coupling means the battery system connects on the AC side of your home’s electrical system, allowing for easier integration with existing solar installations and microinverters. DC coupling connects on the DC side, typically integrated directly with the solar panels and inverter, which can be more efficient but often less flexible for retrofits.

This difference in system design affects installation complexity, compatibility, and system expansion options.

Warranty Length and Value

Franklin Whole Home offers a 15-year warranty on the aPower 2, compared to Tesla’s 10-year warranty on the Powerwall 3. This longer warranty period gives Franklin a significant advantage in terms of long-term reliability and cost savings.

Over the course of those extra five years, homeowners can expect better value, reduced maintenance costs, and fewer worries about replacing or repairing the battery system prematurely.

Higher Throughput with Microinverter Pairing

When paired with microinverters in an AC coupled system, the aPower 2 allows for higher throughput because it is not limited by the inverter’s nameplate rating on the DC side, as is the case with DC coupled systems like Tesla’s.

For example, if a homeowner installs a 15 kW solar system with microinverters and pairs it with the aPower 2’s 10 kW continuous output, the system can theoretically handle up to 25 kW of continuous power. This higher throughput enables more efficient use of solar energy and battery storage, which is ideal for homes with larger energy needs.

Installation Flexibility

Because Franklin Whole Home batteries are AC coupled and compatible with a wide variety of microinverters and string inverters, installation is typically simpler and less disruptive, especially for retrofits. Tesla Powerwall 3 installations often require rewiring or system redesigns if existing solar equipment is incompatible.

This flexibility makes the aPower 2 an excellent choice for homeowners looking to upgrade without overhauling their current setup.

The A Gate: Smart Circuit Management and EV Integration

Beyond the battery itself, Franklin Whole Home introduces an exciting piece of equipment called the A Gate that enhances the overall home energy management experience. The A Gate brings smart functionality to your home’s electrical circuits, allowing for greater control, efficiency, and integration with electric vehicles (EVs).

What is the A Gate?

The A Gate is a smart circuit manager designed to isolate and control large home loads such as HVAC units or EV chargers. By connecting these circuits to the A Gate, homeowners can monitor and manage their energy consumption directly through an app.

This smart management means you can decide when a particular load draws power from the battery or grid, turn it off remotely if it’s pulling too much energy, or set timers to optimize usage. For instance, you might schedule your HVAC to run on battery power only during certain hours when electricity rates are high or when the grid is down.

Electrical Configurations and Common Uses

The A Gate can be configured with one 240-volt circuit and two 120-volt circuits, or these two 120-volt circuits can be combined into a single 240-volt circuit, which is a common setup. Most homeowners use this to manage their EV charger and HVAC system circuits.

By isolating these high-demand loads, the A Gate ensures that the battery’s energy is allocated efficiently and that critical systems receive the power they need without overloading the battery or the home’s electrical system.

Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H) Ready

One of the most innovative features of the A Gate is its readiness for vehicle-to-grid (V2G) and vehicle-to-home (V2H) applications, also known as vehicle-to-load (V2L). This means that certain EVs can act as mobile energy storage units, powering the home or even feeding energy back to the grid.

Compatible vehicles include the Tesla Cybertruck, Ford Lightning, and Rivian models, among others. These EVs typically have large batteries—often around 100 kWh or more—that can serve as a backup power source during outages or peak demand.

With the A Gate, you can plug your EV into your home system and use it as a generator, powering your house and charging your home battery simultaneously. This integration provides an extra layer of energy security and flexibility that few other systems currently offer.

Backup Power and Generator Compatibility

Homeowners often ask about the ability to use generators alongside their battery systems for extended power outages. The Franklin Whole Home system, including the aPower 2 and the A Gate, is designed to be generator compatible.
