Adding a battery to an existing Feather Sound solar system
Retrofit paths, inverter compatibility and panel work for Feather Sound homes that already went solar.
Adding a battery to an existing Feather Sound array is very doable, and the whole project hinges on one question asked in the first five minutes: what inverter do you have?
Three retrofit paths
AC-coupled. The battery brings its own inverter and sits alongside your existing system. Widest compatibility, most common retrofit.
Hybrid replacement. Swap the existing inverter for a hybrid that handles both PV and storage. Cleaner end state, larger scope.
Same-family addition. Some systems accept a matched battery natively. Simplest when it applies, rare when it does not.
What the site visit checks
- Existing inverter make, model and firmware
- Panel capacity and available breaker spaces
- Whether a critical-loads subpanel already exists
- Mounting location, temperature exposure and clearances
- Interconnection implications with Duke Energy
Choosing critical loads
We build the circuit list with you before ordering. On most Pinellas County homes it is refrigeration, internet, lighting and one comfort load — decided deliberately, not by whatever happened to be nearby in the panel.
Monitoring and warranty
Keep the original system's monitoring alive alongside the new battery's, and confirm in writing that the retrofit does not disturb existing equipment coverage.
Next step
Every number worth trusting comes from your own roof and your own Duke Energy usage. Start with the questionnaire or book a consultation and we will scope it properly rather than guess.
