I'm in the process of installing a MultiPlus, Cerbo GX, SmartShunt & SmartSolar.
During the summer, a friend of mine, mainly uses solar to charge his batteries, and then using the relay on a BMV to switch on the charger if the battery volts drop below a defined limit. Last year 99% of his elec was provided by solar.
I will not be having a BMV, is it possible to get my system to switch on/off the charger in a similar way?
