Victron Orion TR DC-DC switches on and off

Dear all,

I started testing my Orion DC DC charger. Which is located in the back of my van and connected to a 200ah lithium battery with internal BMS system. However, when I start my car, it keeps shutting on and off. What am I doing wrong?

The voltage will increase when I start my car, then the Orion will start charging, and the voltage will drop, after this it will switch off, and the voltage starts to rise again and the Orion switches on again ect ect.

I am using the standard settings for lithium batteries.

Thanks for your help!

Is it the orion smart? The voltage drop is likely too high. So when you start drawing current, the voltage drops and the orion thinks the battery is low.


Check cable thickness and low battery voltage setting.
