Hello to all,
this is the first time that i use pylontech batteries.
I build a system from 5 US2000 Plus Batteries, a MultiPlus 48/5000/70 and a Color Control.
There are two things that i don`t understand and i hope you can help me.
I charge the battery with the recommended absorption voltage from 53,2V. I get from the battery the warning "Voltage to high". I reduce this voltage step by strep from 53,2 V to last test of 51,8 V. But i get in every absorption phase the warning "Voltage to high". The datasheet from pylontech shows a value from max 53,5V.
Because of this error message i write to Pylontech, but i get no answer.
The other thing is a little funny.
When the battery is discharge and i start to load the battery, the load voltage and current are like the bulk phase but the MultiPlus shows at the LED float. I switch the Multi off and on again, the charge starts with the same voltage and current but the LED shows bulk.
Did you have any idea whats is the cause and i can do?
When you need more information to help, i can give.
Many thanks in advance.
