Hi.
As written in the title, with my multiplus 48/5000/70-100 I've never been able to
se charging currents above 50A. It might get to 52A but just briefly.
This is not a limitation imposed by the pylontech batteries whose Charge Current Limit is
always at 222A until the SOC gets close to 100%. And even at, say, 97% SOC the CCL is still
at 88A, so well above what I get from the multiplus.
Obviously the "limit charge current" setting in the DVCC is not active.
Any ideas?
Hi @jterrag
Have you checked the Charge Current value set in the Multi itself? Don't expect it to come with the default set at 70A, it's usually down around what you experience. 55A from my memory of long ago..
With a Mk3 via victron connect or veconfigure. The AC limit is probably hard-set to 50A.
The inverter must still be manually setup, as per the pylon guide. When the GX stops or is restarted the chargers revert to manual and you will have a problem if defaults are set.
Same applies to MPPT's etc.
AC Input current limit? Manual DVCC charge current limit?
About the DVCC charge current limit, as I wrote above that setting is not active. However, after my original post I tried to activate it so that the field with the Amps would appear. And, suspiciously, that field default to 50A, not 70A or 60A. So it seems to take that value from somewhere.
Also, I tried to raise it to 55A, and the system seemed to accept it, but then the charge current again didn't go above 50A.
Based on all the comments above, as soon as I can stop the multiplus I'll connect it to mk3 and take a look at its settings and see if there's something stuck at 50A.
This is also something I had doubts about: should I turn off and then on the multiplus each time I go from having it attached to the Cerbo to attaching it to the mk3? (and viceversa when I go back to the Cerbo). OBVIOUSLY all of this would be done with AC-in disconnected.
So far, to be safe, I've always done it that way.
