To address utility concerns about “losing control” or “frying the lines”:
| Feature | Requirement | Why it works |
|---|---|---|
| Grid Primacy | “Smart Inverters” (UL 1741-SB) are mandatory. | They automatically cut solar/battery export if they detect the local grid voltage getting too high, preventing line damage. |
| Storm Watch | “Override Protocol” | If the National Weather Service issues a severe storm warning, the Utility Control is automatically suspended, and batteries charge to 100% to prepare for the blackout. |
| Warranty Protection | “Cycle Cap” | The utility contract is limited to ~50 full discharge cycles per year to prevent degrading the homeowner’s battery life prematurely. |
