MPPT 450 RS (VE.Can) are in ext.control but the MPPT will not listen to the Multiplus/Cerbo or itself regarding the charge curve.
I have two ea. Multiplus-II 5kVA in parallel, Cerbo GX, Lynx Shunt, Lithium-ion battery with standalone BMS, MPPT 450 RS 100 and MPPT 450 RS 200. All devices is updated to latest Firmware.The system is set up with ESS and VDE Grid-code. In VE Configure I have selected “System uses LiFePo4 with other type BMS”
With the DVCC enabled the MPPT 450 RS are in the ext.control State. When charging the batteries, the Multiplus follows his parameters regarding bulk, absorption and float. But the MPPT’s keeps full charge and will not stop before I turn the MPPT off in the VictronConnect APP.
It uses SVS and the Lynx Shunt as battery monitor and BMS control is OFF.
All VE.CAN devices have the same Device ID and there is no errors or losses on the VE.CAN communication. The MPPT 450/100 is Group master and the MPPT 450/200 is Slave.
DVCC SCS is “Disabled (External Control)” and under System Setup the “Solar charger Current Control: OFF”
Could these two setting be the reason for this strange behavior?
Any troubleshooting ideas are most welcome.
