- Homes that need high output and future storage expansion
Questions this product must answer
- Is the project new solar, a retrofit, or both?
- How many roof planes need independent solar tracking?
- Which loads must start and run during an outage?
- Would aPower S, aPower 2, or a mixed FranklinWH design be the better fit?
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.
