FranklinWH aPower 1 vs. aPower 2: Key Upgrades Explained
If you live in Texas and are considering adding backup to your solar system, incorporating solar battery storage is no longer a luxury — it’s a necessity. It protects your excess solar power and keeps your home running during blackouts. Among the leaders in this field, Franklin Whole Home (FranklinWH) has raised the standard with its award-winning aPower battery line.
The first-generation Franklin aPower 1 (also known as aPower X) became a favorite for its flexibility and generator compatibility. Now, FranklinWH aPower 2 takes energy independence to a whole new level — with more power, more capacity, and a longer warranty. Let’s look at what makes this upgrade so important for homeowners in Houston, Texas.

Double the Power — for a True Whole-Home Backup
The most significant improvement in the aPower 2 is its doubled continuous power output — now 10 kW compared to the 5 kW of the previous model. This allows one single battery to handle energy-hungry systems like air conditioning units, EV chargers, or heavy home appliances without needing multiple batteries.
For many homes across Greater Houston, this means you can now power your entire house seamlessly with just one battery — an incredible upgrade for both performance and affordability.
More Storage, More Freedom
The aPower 1 delivered 13.6 kWh of capacity, already enough for moderate usage. The aPower 2 pushes that to 15 kWh, offering longer runtime during outages and greater flexibility for solar energy storage. It’s ideal for Texans who want to stay comfortable during heat waves or unpredictable grid interruptions.
Longer Warranty and Exceptional Lifespan
FranklinWH continues to lead with its reliability and confidence in engineering. While the aPower 1 offered a strong 12-year warranty and 43 MWh throughput, the aPower 2 extends coverage to 15 years and 60 MWh, marking one of the longest and most robust warranties in the market. This translates into a higher return on investment and peace of mind for years to come.
Advanced Cooling — Whisper Quiet Operation
Unlike traditional fan systems, the aPower 2 uses a fan-less convection cooling system, maintaining an ultra-quiet sound level of around 30 dBA. This not only ensures silent performance but also reduces wear and tear, eliminating the mechanical components that often fail over time.
Modern Design and Rugged Build
The aPower 2 features a sleek new aesthetic with a vertical LED status light that communicates real-time system information. It maintains its IP67 rating, protecting against dust and water, and continues to perform in extreme Texas conditions — from -4°F to 131°F.
At 10% lighter, installation is also faster and easier — something both homeowners and our certified installers at Solstice Solar appreciate.
