Hi All
Client has a Multiplus II 48 | 5000 with a MPPT 250 | 100 with a Cerbo GX. System was installed with a single Dyness 5.12kWh battery and client has added a 2nd one of these batteries now.
Comms to the batteries seems to be fine but monitoring figures does not seem to add up now:
1356W seems to go missing from looking at the below?
Would greatly appreciate assistance
Are you relying on the batteries to report charge current rather than a Victron shunt.
1356W is missing, which is pretty close to the reported 1439W going to the battery, simple thought is the new battery is also charging with approx 1400W but it is not reporting this.
Does this mean that the shunt is required to report the stats of the 2nd battery?
Should the BMS not be bale to report this back to the system?
If both batteries are present on the GX, they should both be reporting their current.
Would you mind sharing a screenshot of that?
Hi Guys.
Issue solved. The installers of the system connected the comms cable from inverter to the battery into the OUT port on the battery. No idea how, but this seemed to have worked. With the install of the 2nd battery, the cable got connected to the available IN port on the first battery to the OUT port on the new battery.
Swapped the cables around and now working perfectly. Thanks for all the help!!!
