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?
- 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
