firmware issues going from 1phase to 3 phase MultiPlus-II GX 48/5000 + 2 MultiPlus-II 48/5000

I had installed a MultiPlus-II GX 48/5000 about in Decembre 20121 with 8 Pylontech US2000.
This is a one phase system and I wanted a 3 phase system, so I bought 2 MultiPlus-II 48/5000 extra.
Further: Gridmeter CG EM24 Ethernet Energy Meter
Solaredge 3phase 10kW

when connecting I got this message:

Automatic monitoring alarm - VE.Bus Error: VE.Bus Error 25: Firmware incompatibility. The firmware of one of the connected device is not sufficiently up to date to operate in conjunction with this device
VE.Bus System [275]


So both the MultiPlus-II 48/5000 was updated with software to 506 (21 August)
The MultiPlus-II GX 48/5000 was updated to v3.01


After reconnecting everything (29 August) I still got
Automatic monitoring alarm - VE.Bus Error: VE.Bus Error 25: Firmware incompatibility. The firmware of one of the connected device is not sufficiently up to date to operate in conjunction with this device
VE.Bus System [275]

What to do? Are these not compatible?

Did you update all the inverters?

They are little far out in date, just outside of the 6 months.

Make a new one that master after that.
