No MultiPlus-II 48/5000/70-50 in device list after FW-Upadate Cerbo GX 3.10

Hello,

I updated my Cerbo GX to v 3.10 and after that there was no
MultiPlus-II 48/5000/70-50 in the device list any longer.

On the dashboard it is still there, but it shows "wrong" values as it says the battery is discharging with 520W whereas the "display" shows charging with 2000W.


Any ideas how to bring the MultiPlus-II back?

Best regards

It's a known bug. You need to update the MK3 module of the GX device.

Go to the remote console -> device list -> MultiPlus and the should be a hint that there is an update for the MK3, do the update and the MultiPlus should appear in the VRM update list.

However there is still a difference between -500w /discharging and +2000w/charging as shown in the secound picture.

???

2799W from PV - 2195W into battery = 604W DC load -> with efficiency loss 528W AC load (around 87% efficiency)

On the one hand it says that the battery is charging with 2000w and at the button of the page it says discharging with 500wcebrofw.png

The battery is charging because you have PV production and the MultiPlus is taking 519W from the battery.
