System is a Multiplus II 5000/48 with a BYD B-Box pro 10kWh Lithium set connected to VE.Can on my Cerbo GX with the Can-speed set to high.
I have two PV-sets. One connected through a SmartSolar Charger VE.Can 150/70 connected to the second Can-bus on my Cerbo GX at normal speed. The second PV-set is connected through a BlueSolar Charger MPPT 150/35 rev3 connected to VE-Direct.
The loads are covered by the batteries with both chargers working at top performance and the batteries are charged of course.
That works ok until...... the batteries are at 100%. Then the set connected to VE-Direct keeps working at top performance, covering the loads and bringing the excess to the grid.
But the set connected by VE.Can is switched off, not doing anything anymore:-(
And, as that PV set is normally producing the most power, this is kind of a bummer.... ;-)
Of course at the end of the day, if the set connected to VE-Direct isn't able to cover the loads on it's own, and the batteries are depleted a bit, the VE.Can MPPT kicks in again and start producing again until the sun goes down completely.
I changed an older VE.Can MPPT for the VE-Direct one and then a new menu-item appeared called Networked operation?!
With the VE.Can MPPT it says Group Master and at BMS controlled it says Yes.
With the VE-Direct MPPT it says Slave at Network status, Ext. control & BMS at Mode setting and Yes at BMS controlled.
I'm not sure if these screens have anything to do with the problem, but as the menu-item appeared after changing an OLD VE.Can MPPT for the VE-Direct one, I thought it could have to do with these problems. Before changing the OLD VE.Can MPPT, BOTH MPPT's were shut off when the batteries were full, bringing no power to the grid at all...
Is there one of you who had this problem and/or may have a working solution?
