Hi, I'm having a strange behaviour with my system.
Using with latest firmware:
SmartSolar Charger MPPT 100/20 48V
Cerbo GX
MultiPlus 12/1600/70-16 is connected to Cerbo GX through Ve.direct cable
SmartShunt 500A is connected to Cerbo GX through Ve.direct cable
VE.Bus BMS V2 is connected through RJ45 Cables to Cerbo and to Multiplus
2x LIFEPO 330Ah connected to VE.Bus BMS V2
Orion TR DC-DC smart
2x Battery Protect 100AH ( DC loads connected to BP1(out), MPPT and Orinon DC-DC connected to BP2(in) )
DVCC is enable in Cerbo
The setting for DVCC from the Cerbo:
Limit charge current :disabeld
Limit Manged Battery Charged Voltage : Disabled
SVS STS SCS -enabled
SCS status : active!
The problem is that when I power everything, the BP2(in) that receives DC only from the MPPT is throwing E4 ( overvoltage) and it shows 16.2 to 16.4V.
If I disconnect the input from the MPPT from the BP2(in) and measure the output voltage straight on the terminals it shows 16.2 to 16.4V.
If I disconnect also the Ve.direct cable from the MPPT it gets back to 14.2V
I'm sure that I miss something in the Cerbo setings, but don't know what?
