I want to control the charging current of a multi2 GX 48V 3000 with a analog input .
I have allready a ESS system and want to add this feature Ladestromsteuerung.
I have a external current sensor - it deliver 0..2,33 V acording the power of a PV inverter.
I want to reduce the charging current of the Multi - if not enough power comes from this PV.
For 2,33 I want maximum , for 0V I want minimum DC charge current
I have measured the voltage is comes to the Multi but if I activate the Assistant for charge current - the battery is not charged anymore.
If somebody has a idea how to make it work - would be great.
