Connect MPPT 250/70 Tr to Multiplus 2

I have bought three 250/70 MPPT's for connecting to my three Multiplus 2. I actually followed the Victron MPPT calculator and bought the Tr version without VE Can. It only has VE Direct but what I can't find is that if I can use the VE direct version also with the MP2 as master for monitoring the SOC, feed in excess PV power to the grid etc etc.

The three 48V MP2's are not synced together, all three standalone GX devices charging and discharging LFP batteries

VE direct does all you need.

However check the BMS communications. Many can talk to the GX in your multis and control the charging. Probably needs a special cable.

So even with just VE Direct the Multiplus GX device is fully in charge (lol) and acting as a master to control the behaviour of the MPPT and the PV power
