ESS working well when SOC~100%, feeding all excess power to grid.
But in morning when energy price is high I want to set ESS to feed to grid all excess power even if battery is not charged. How to set ESS mode 2 for this situation?
Tested 1:
/CGwacs/MaxDischargePercentage = 0
/CGwacs/MaxChargePower = 0
/CGwacs/AcPowerSetPoint = -5000
- this works perfect when AC loads are low and there is is excess PV power.
Problem is when AC loads are higher than PV. It takes power from grid instead of battery (obvious because MaxDischargePercentage = 0)
Tested 2:
/CGwacs/MaxChargePower = 0
/CGwacs/AcPowerSetPoint = 0
- no effect. Still charging bettery with excess PV power
Tested 3:
/CGwacs/MaxChargePower = 0
/CGwacs/AcPowerSetPoint = -5000
- also bad. Will discharge battery to grid if there is not enough (5kW) of excess PV power
Any idea how to achive this?
Thank you for any help.
