Two MPPT showing on CCGX but not in VRM-portal

Hello together.

I have a Victron system consisting of:

  • CCGX (updated to the latest available firmware)
  • MultiPlus (updated)
  • Two SmartSolar MPPT 250/60 controllers
  • Pylontech batteries
  • VRM Portal

After updating the CCGX firmware, both MPPTs are correctly detected locally on the CCGX.

The two MPPTs are named:

  • MPPT OW
  • MPPT Hunde

In the CCGX device list, both MPPTs are visible and show plausible individual power and yield values. For example, in the morning MPPT Hunde (currently connected to the East array) produces more power than MPPT OW (currently connected to the West array), which is expected.

However, in VRM I observe the following issues:

  1. Second MPPT not shown correctly

In the VRM web portal, macOS app and iOS app, the “PV Charger” section only shows MPPT OW.

The total PV production appears to include the contribution of both MPPTs, but only one charger is displayed.

When I compare:

  • Total PV production
  • Production shown for MPPT OW

the difference corresponds approximately to the production of MPPT Hunde.

Therefore it appears that data from both chargers is being received, but only one charger is displayed in the user interface, but the values I see are from MPPT Hunde, but show up as MPPT OW

Additional information:

  • Both MPPTs are visible on the CCGX.
  • Both MPPTs have Device Instance 258.
  • Both MPPTs are connected via VE.Direct.
  • Both MPPTs are running and charging correctly.
  1. Load values appear inconsistent

In VRM I have the tiles:

  • AC Loads
  • Essential Loads
  • Total Consumption

The value shown for “Total Consumption” appears to be simply:

Total Consumption = AC Loads + Essential Loads

This seems incorrect in my installation and may result in double counting.

Could you please advise:

  1. Whether both MPPTs having Device Instance 258 can cause only one charger to be displayed in VRM.
  2. Whether the second MPPT should appear as a separate device in VRM.
  3. How Device Instances can be changed for SmartSolar MPPT 250/60 units if required.
  4. Whether the Total Consumption calculation described above is expected behavior.

Thank you for your assistance.

Best regards,
Heiko

Areyou able to provide screenshots.
I would expect with ve direct there would be 2 vrm instance number like 258, 259.

Disconnect ve direct of 1 mppt, reboot the ccgx.
After logging begins again, reconnect the mppt. Check is the instance has chnaged?
