# Charge to min SOC -> Optimize Self-Consumption

Initial State: Charge to min SOC
Target State: Optimize Self-Consumption

Test Procedure

1. The battery is discharged below 20% SOC
2. Min SOC is set to 20%
3. A production surplus is simulated by setting the Grid setpoint to a positive value (1200W)
4. Wait until the SOC exceeds 22%

Expected Outcome

The system assumes the Charge to min SOC state and charges with high power (~2000W), until it reaches Min SOC.
Once it reaches Min SOC it does the following:

• it changes into the Optimize Self-Consumption state
• it continues to charge the battery with an average of 1200W
• charging power does not fluctuate by more than 250W once it has stabilized

Tested Outcome

The system reacted as exactly as expected and switched to Charge to min SOC and charged as fast as possible till reaching the Min SOC.
Once the Min SOC is reached, the battery switches to Optimize Self-Consumption, where the charging power fluctuations don't exceed 200w.
