deligreen bms increases voltage

[st2121]

hello everyone,,my nane is steve andi live in Greece and i have an off grid 24v system !
i have 3 x 450w sharp panels 4 x 295w a studer inverter 2x vitron mppt 100/50 and a victron smartshunt..
my system had 4 250 ah gel battery and evrything was working fine for 2years.a week before i decided to install 8 eve lifepo4 cells and a deligreen bms 24v 8s 200a!
when charging the battery and the voltage is 26,1 v for example..from no were the voltage rises to 28.4,,and the mppt controllers kick to absorption with no watt or current showing going in or out from the shunt readings,if i charge with generator with a smart charger victron 16a 24v the same happens.i tried the same with out the bms and evrything is working perfect,,,so the bms increases my voltage. i tried different setting but same thing over and over.when i check the voltage when it rises from one side of the bms that goes to the baterry pole is 26.1 and the other side that goeas to the shunt its 28.4.
i have tried a second same bms and the same thing happens.i have removed the smartshunt but no difrense,,it increases the voltage again,
any ideas or help is welcome..thanks for your time!

i have ordered a jk bms b2a8s20p and give it a try,,,,with the daly bms 4 days now and nothing,,,i have disconnected everything off and when i put a charger immediately increases the voltage to 28.4 and stops .i have even installed the pc program and all settings are ok,,,so i gave up and ordered an other bms to try.

after speaking with someone from deligreen he told me that level 1 is warning and level 2 cut out,,so i fix the values and again the same,,,i hook only a victron charger and same happens.waiting for answer from the sales man .

well just to update,,the jk bms arrived ,hooked up and working perfect for 4 days now,,,so i ordered one more for the second battery bank,.
Looks like daly bms are not for me!
