Hi, I have a system with 3 MPPT´s , two 150/35 connected via VE.Direct to a CerboGX and one 250/100 connected via VE.Can to the CerboGX, this works perfect The problem is that when I connect another MPPT 250/85 via VECan it don´t synchroniz with the others. It consider it self to be “standalone” …

Hi Nicke, Yes, they should VE.Can and VE.Direct MPPT charge controllers can be synchronized. Do you have a Cerbo GX or GX device and have you enabled DVCC. 12. DVCC - Distributed Voltage and Current Control Once DVCC is enabled, the VE.Can and VE.Direct MPPTs will coordinate their charging. In…

Hi Dave Yes, I have a CerboGX and DVCC is enabled. There is synchronization between the two 150/35 (VE.Direct) and the 250/100 (VE.Can) But the newly installed 250/85 (VE.Can) vill not synchronize with the old ones. /N

Hi Nicke, Did you get this sorted? If not, it could be faulty and time to RMA it. But do some checks first > Pre RMA checklist Good luck. Dave.

Hi Well, I got it “sort of” sorted I connected the MPPT via VE.Direct and it started to behave as “slave” and syncronized charging with the others. Not the way I wanted but it works for now. Dont have any ideas what could be the problem with the VE.Can /Nicke

I have two 150/35s connected via ve.direct to a cerbo-s. Then I have a 250/100 and 450/100 connected via ve.can. Only the two ve.can connected sccs show an entry for “Network total power” in VC, the ve.direct connected sccs arent included. I asume this is normal as the ve.direct and ve.cans arent c…

I just posted this:

I managed to get VE Can Bus paralleling two MPPTs and reporting via DVCC with a SmartShunt and Color GX, but I had to do this and it isn’t well documented:
