I have a boiler that is 2000watt and a Victron multiplus 12/3000
I want to be able to determine the wattage it uses so I want to place a (3000watt) dimmer before the boiler. So I can spread out the load of heating water and make hot water on sunny days when the solar panels are working and I am not connected to shore power.
Is this possible with this thing:
