SmartSolar 75/15 not receiving external

Hi There,

I have the following setup:

  1. BMV-712 Smart
  2. Smart Battery Sense
  3. MPPT 75/15 (QTY=2)

One of the MPPT’s is receiving external Voltage and Current sense from the BMV (and temp from Smart Battery Sense).

The other is only receiving Voltage from the BMV (and temp from Smart Battery Sense).

It seems to be the same in Bulk and Absorbtion. (unsure about float at the moment).

I have just updated the Victron Connect App (Andriod) and the Bluetooth interfaces on the MPPT. Everything is on the latest version as far as I am aware.

Actions Taken:
I have powered on/off the BMS
I have removed/added back the MPPT controller to the network.

Any ideas?

Thanks in advance,

Simon

One mppt will be the master one will be the slave.
So only one will use the current sense.

From the manual

Summary

How synchronising works on solar chargers

Synchronising the chargers works in a master-slave manner. The chargers will elect a master among them and that master will be the one to dictate the charge algorithm. As the master cannot be determined by the user, it is important to make sure all chargers belonging to the same network have the same battery settings. To know more about the battery settings and some other information, check the solar charger manuals.
