The Amber app now supports switching the Zappi between FAST and ECO+ mode automatically as required. When the Excess Solar Charging toggle is enabled, the Zappi will be switched to ECO+ mode unless some other condition causes max-rate (FAST) charging.
| Condition | Zappi mode | Description |
|---|---|---|
| Charge Until Disconnected is enabled | FAST | EV will charge at max rate until disconnected, in response to manual override in the Amber app. |
| Grid usage price is below your Opportunity Charge Price | FAST | EV will charge at max rate to take advantage of low grid price. |
| Charge schedule is enabled and time is inside schedule window. Grid usage price is below Max Price, if configured. | FAST | EV will charge at max rate during schedule window. |
| Grid feed-in price (FiT) is above solar Maximum Feed-in (optional) | STOP | Charging will be stopped if the grid feed-in price is above the (optional) Maximum Feed-in price. This allows exporting excess solar instead of using it for EV charging when the value is high. |
| All other times | ECO+ | EV will charge from excess solar only when no other condition is active. |
Charging will stop when the amount of excess solar is below the minimum charge rate of your equipment, see below for details. |
The conditions in the above table are listed in priority order: the first condition to match will determine the charging action.
