'Ignore AC input' stopped working after firmware update MP-II 3000

I have a customer with:
- MP-II 3000 48V 30/50
- 4 x Pylontech US2000B
- MPPT 150/60
No GX device, no data connection, other than local VE-bus and Bluetooth
It has access to a mains supply available at certain times of the day (L1).
It all worked well, for about 18 months, then it ceased selecting the mains supply via the Virtual Switch. Customer believes it was after one of the firmware updates.
Please see the below screenshots and advise?
vs-ignore-ac-setting.png- Dedicated Ignore AC input (therefore no Assistants)
- Power Assist=on; current boost factor 2

Please advise how I should load a firmware version from (say) April 2019?

Thanks Chris

Dear Sir ,


The easiest solution(for remote monitoring). Get a raspberry pi computer, and as many VE.Direct USB cables for all your devices and make a Generic Genus device( there is an image available online ) to monitor everything remotely ( if there is internet access even better )

Now regarding FW wise:

and also the older FWs are available on

Thank you in advance

I may have missed something fundamental:
Is the firmware for MP-ii updated automatically?
Ie, is the firmware checked and updated whenever you connect to the inverter using VEConfig?
Also
Is there a way of checking the firmware version without opening the cover of the inverter?
Thanks
