I have sailboat with 2 solar panel 365W each , with 2 MPPT 100/30 and BMV702. On a sunny day at 10am all my (4) batteries (200A/hour each) are charged 100% and I want to use the excess energy from the solar panel to heat my water tank. (1500 W /110Vac). I have 3000W inverter from 12VDC to 110Vac. What kind of set up i need to heat up this water tank. Is victron energy has a monitor/equipment that can switch once the battery reach 100% charged to heat the water tank? If yes please provide more detail information.
