As Texas homeowners face increasingly unpredictable weather, rising energy demands, and the need for reliable backup power, choosing the right home battery system has become more important than ever. With frequent grid outages, extreme heat, and growing reliance on electricity, whole-home energy storage is no longer a luxury—it’s a necessity.
Among today’s leading energy storage solutions, FranklinWH continues to stand out with the release of the FranklinWH aPower 2. Building on the success of the award-winning aPower 1 (also known as aPower X), the aPower 2 delivers meaningful improvements in power output, storage capacity, reliability, and overall system performance.
This guide explains why the aPower 2 is quickly becoming one of the most popular battery upgrades for Texas homes.
FranklinWH aPower 1 vs. aPower 2: Key Differences
FranklinWH designed the aPower 2 to better meet the demands of modern homes, especially in energy-intensive regions like Texas.
| Feature | aPower 1 | aPower 2 |
| Usable Capacity | 13.6 kWh | 15 kWh |
| Continuous Power Output | 5 kW | 10 kW |
| Warranty | 12 years / 43 MWh | 15 years OR 60 MWh |
| Cooling | Natural air-cooled | Fanless convection cooling |
| Weight | 395 lbs | 357 lbs |

These improvements make the aPower 2 a stronger solution for homeowners seeking dependable whole-home backup.
More Power for Whole-Home Backup
One of the most impactful upgrades in the aPower 2 is its increased continuous power output. With 10 kW of continuous power, the aPower 2 can support high-demand household loads such as air conditioning, large appliances, and EV chargers more effectively than previous generations.
For many Texas homeowners, this means fewer batteries are required to support essential systems, making whole-home backup more achievable and efficient.
Increased Storage for Longer Outages
Extended outages are a reality across Texas, and sufficient energy storage is critical. The aPower 2 increases usable capacity to 15 kWh, allowing homeowners to:
- maintain power during multi-hour outages
- store more excess solar energy
- improve resilience during extreme weather events
This added capacity makes the aPower 2 especially well-suited for solar-powered homes focused on energy independence.

This structure ensures dependable operation and long-term value for homeowners investing in energy storage.
Quiet, Maintenance-Free Cooling
The aPower 2 features a fanless convection cooling system that operates quietly and efficiently. With fewer moving parts, the system reduces wear and tear while maintaining stable performance.
Benefits include:
- quiet operation suitable for garages or interior spaces
- improved long-term reliability
- reduced maintenance requirements
Durable, Weather-Ready Design
Built for demanding environments, the FranklinWH aPower 2 includes:
