The second reason to consider the Franklin system is its AC coupled architecture, which is distinct from the DC coupled systems employed by the Powerwall. This design is advantageous for retrofitting battery storage to homes with existing solar panels. The flexibility of being compatible with various solar inverters means that homeowners can easily integrate battery storage without needing costly alterations to their current setup.
By leveraging AC coupling, installation work is streamlined, primarily taking place at ground level—the AC circuit breaker panel—eliminating the need for roof modifications or warranty concerns associated with existing solar equipment.
