Hi! I have a MultiPlus 12/3000/120 an a 3kw pv. I am producing during the day 1500Watt "too much" energy. For this I can adjust my MultiPlus in the VictronConnect App how much AC input the charger should use. I would like to automate this and my question is if that is possible and what do I need for that? Just simply use an ET340?
