Hi @Izak ,In the boats normally have a diferents systems for recharge batteries. Some times if install all device victron don't have problems to monitoring, but when install new system solar charge in the boats there is a one charger and alternator and wind generator, what the customer wan't replace it and the victron monitoring is very expensive for only solar production. If install new smart shunt for each equipment and assing the role ( charger, alternator, wind generator ) only show the amps,volts and power. I think with this application to be more adaptable the GX family. Thaks
