Hi I have a problem with my MP2 in paraller, (2x MP II 5000, 2xPylontech 5000 - CAN, CerboGx, PV Hoymilies 6000kWp) everything working perfect only charging battery stop at 70Amp, PV assistant set freq shifting to power down PV. In cerbo is set charging current to 100 Amps, (on MP is default 70Amps) It looks like that master MP2 is “thinking” is alone :).
Did you install and program this equipment yourself?
There are so many other settings or problems that can affect charging from AC and charging in general.
Look in DVCC
In advanced the CCL and DCL widget
And then the charger tab in the inverters themselves. If you are able.
Yeah but then you have limited the whole system to 100A. In DVCC. So it will slow charging from all sources to that.
51.3v is also too much of a limit even for pylons. Program according to this guide.
Remove the limits in DVCC.
Yes that is what the battery wants and the system can’t give it that. Follow the guide. If it foes not charge correctly. Then we trouble shoot some more.
