Victron Orion-Tr 48/48-6 AGM and LiFe4Po

Hi,

I want to use the Orion-TR to charge a LiFePo4 battery. An AGM battery serves as the source. Both are 48V systems. The output voltage of the Orion was set to 53V without load. If it is switched on, its not charging. If the output voltage manually is turned up, it starts to whine. The charging power is about 6A, but the BMV-700 at the AGM shows me about 20A of discharge. If the voltage is reduced, the whining stops. If the contact for charging is then opened and closed again, it will not charge again.

Does somebody any idea what kind of fault it could be? The manual is not helping.

greetings

Sven
