I am rebuilding the charging system on my boat (700 Ah Firefly battery bank). I have two 150/70 VE.Can MPPTs and a smart shunt on the ground return. The MPPTs are VE.Can cabled to a cerbo GX and the smart shunt is connected to the cerbo via a VE.direct line. The 1200 W solar can deliver up to 100 amps at peak into the batteries. A few questions:
1) is the network between the MPPTs and shunt done over Bluetooth or does the cerbo broker the conversation using the VE.can and VE.direct feeds? I much prefer hard wired connections
2) depending on (1), I may need to downgrade from a smart shunt to a shunt that has analog sense outputs that can be used by my new wakespeed 500 alternator regulators, as they don’t yet have support from Victron to get the VE.can data from the cerbo (per wakespeed rep). I love my smart shunt but without analog sense wires I’d either have to put another shunt in series or just swap out the smart shunt for an older one with both VE.direct and analog out.
