Tristar MPPT 150/60 fault code battery high voltage disconnect

globenomaden

Hi folks

I have justed installed a new Tristar MPPT 160/60 on my 24 Volt system in a RV.

I have set the DIP switches 2 to on and 3 to off for the 24 Volt system. I also checked the Auto voltage setting withno sucess.

First I powered the battery voltage and got a constant greed LED. Afther switching the Solar array to on (Voltage input appr. 70 Volt) I got a blinking code of two green and one red in sequence and no charging. The manual says battery high voltage disconnect which could not be true. What could be the problem. Please help me out. Many thanks

best regards

Alfred

What do you have the battery type set to, and what do the battery terminals on the controller measure?

 I have a Lithium battery type which absorp Voltage of 28,8-29,2 Volt. the battery terminals measure 26,9 V which is exactly the voltage of the battery. I have set to lead acid flooded DIP switch 5
