I have a cerbo GX (v3.52) connected to 2x multiplus-II in parallel via VE.Bus, JKBMS via canBMS CAN-bus, SmartShunt 500a(v4.16) via VE direct, Energy Meter ET112 (currently off) via RS485 - USB and 2x SmartSolar MPPT VE.Can 250/100 rev2 (v3.16) via VEcan.
Since March 14th the SmartSolar SCC (bottom) stopped charging even though the batteries were not fully charged and the second SmartSolar (top) SCC continued charging. I noticed the issues on the 26 March, I powercycle both units and the issued resolved. But recurred the following day, over the next few days I replaced cat5e cables (on the CAN) and moved the SCC in to a different order connecting bottom directly to the Cerbo and Top scc and terminating top.
The issue seem to have gone away until yesterday. I hope you can help me with this issue i check every think i can think off.
the next thing i’m considering is switching the solar panel to see if they are what is causing the issue.
thanks Simon
