I’ve just fitted a Cerbo GX to my boat. My set up is 780w solar panels, 100/50 Victron MPPT, multiplus inverter which hardly gets used as the boat is mainly a 12v set up and a smart BMV 712..
I’ve fitted a 300w 12v element to my hot water tank which works well, it’s wired in by a manual switch that I have to switch on and off.
is there a way of getting any excess solar load to heat the water when the batteries are at 100%.
Possibably to be able to trigger it remotely via the cerbo when we are going to the boat to arrive to a tank of hot water.
Thanks
