Key strengths
- Large capacity in a single battery
- LFP chemistry and passive cooling
- Generator integration within supported designs
- Scalable architecture for larger homes and projects
Best suited for
- Homeowners prioritizing long backup duration
- Projects that benefit from generator coordination
- Larger homes or systems that may expand later
Questions this product must answer
- Is generator integration part of the resilience plan?
- How many large loads may operate together?
- Where can the battery and aGate be located?
- Does the home need circuit-level load controls?
The complete system still matters
Capacity, output, efficiency, and warranty narrow the field. The final choice must also fit the roof, electrical design, permits, utility, and service plan.
Any proposed equipment substitution should be documented and reviewed before installation.
