Why homeowners consider it

Strengths worth putting into context.

  • Large capacity in a single battery
  • LFP chemistry and passive cooling
  • Generator integration within supported designs
  • Scalable architecture for larger homes and projects
Often a fit for

Projects with these priorities.

  • Homeowners prioritizing long backup duration
  • Projects that benefit from generator coordination
  • Larger homes or systems that may expand later
The design conversation

Questions we answer before specifying aPower 2.

  1. Is generator integration part of the resilience plan?
  2. How many large loads may operate together?
  3. Where can the battery and aGate be located?
  4. Does the home need circuit-level load controls?

Specifications are only the starting point.

Published capacity, output, efficiency, and warranty information help narrow the field. A valid Florida project also requires compatible electrical design, roof or mounting review, permits, utility interconnection, manufacturer instructions, and a clear service plan.

We use the current manufacturer documentation when preparing the final system scope. If equipment availability changes, any proposed substitution should be documented and reviewed before installation.
