# Optimize Self-Consumption -> Bridge Grid Blackout -> Charge to min SOC -> Hold min SOC
|
|
|
|
Initial State: `Optimize Self-Consumption`
|
|
Intermediate State: `Bridge Grid Blackout`
|
|
Intermediate State: `Charge to min SOC`
|
|
Target State: `Hold min SOC`
|
|
|
|
## Test Procedure
|
|
|
|
1. `SOC` should be 50% or lower
|
|
2. `min SOC` is set to be at 5% or more below the current `SOC`
|
|
3. `Grid setpoint` is set to 0W.
|
|
4. a load (min 1000W) is connected to the AC-Out side of the inverter.
|
|
5. A grid blackout is simulated by manually disconnecting the system from the grid
|
|
6. The system is left without grid until the `SOC` drops at least 1% below `min SOC`.
|
|
7. The system is connected back to the grid
|
|
|
|
|
|
## Expected Outcome
|
|
|
|
- The system first is in the `Optimize Self-Consumption` state.
|
|
- As soon as the grid is disconnected, the system changes into `Bridge Grid Blackout`, as visible by the "inverter on" LED on the inverter.
|
|
- the load must not loose power
|
|
- the Venus controller will loose power for a short time and then reboot
|
|
- as soon as the Venus has rebooted, the controller should resume in the `Bridge Grid Blackout` state. (It may transition through the `Unknown` state, but it must not stay there for more than 30 seconds)
|
|
- after the grid has been reconnected (when the `SOC` dropped at least 1% below `min SOC`), the inverter synchronizes with the grid and switches back to charger mode ("mains on" LED on the inverter is lit). This should not take longer than 3 minutes.
|
|
- the Venus controller should then change into the `Charge to min SOC` state.
|
|
- the system should charge to `min SOC` with at least 1500W
|
|
- once `min SOC` is reached, the controller should switch to `Hold min SOC` and the `SOC` should stabilize slightly above `min SOC`.
|
|
- during the whole procedure the load must never loose power
