also thank you for you input

hey thanks for getting back to me , i already updated the firmware to 54.06 and the MCU to 22.21. but as you said earlier the SOC % option was not available can i use a different firware like the 72.xx or 82.xx to solve this? also note i found somewhere a firmware version 54.63?! .. is this ok to use? i tried contacting voltronic through there Contact us page ... but i do not get any replies. the company that sold me the inverter is long gone ... so that is a dead end for me.

Hi Hope you can help ... And no it is not twin from what I got to realize...

hello and thanks for the quick reply the cable is connected the 3 green lights of the wifi are on and the BMS is working correctly and communicating with the inverter. i will attach images . the problem is and what i found online.... is that the inverter uses the same module for bms and wifi... so only one of them can be active at a time but even if i disconnect the bms and power cycle i can't access the menu and the inverter is stuck at the bms mode ED5 ... cant change Cut off voltage (should be percentage i think) it is stuck at 48v ... and the batteries are being completly drained ... i have contacted the BAttery Supplier (Batteries are Dyness 14.33kw) and he said the switch from battery to utility should be done at the inverter level not the battery/bms level the batteries are connected corretly and the DIP is 0100 on master and 0000 on slave the inverter firmware i have is 54.01 ... Edit. i think the correct menu number is 36 Ad5

hello there , you seem to know a lot about the voltronic inverters and if you could help me out i would be really grateful i have a Axpert MAX II TWIN 8KW with firmware version 54.01 i have connected a lithium battery through BMS to the inverter .. first problem is the WIFI no longer works second i cant change the settings in the inverter menu on the touch screen ... and the cut off voltage is in V not in percentage and i cannot change it manually the inverter is stuck in ad5 and cant be changed i was thinking of upgrading the firmware ... but not sure after reading the posts here i am confused there r multiple firmware versions? different firmwares for the CPU and the touch screen? is there anywhere a video i can use to follow for that or a step by step guide? i work with computers and know my way around ... but the inverters is a first for me .. so don't want to brick it any help is appreciated
