Orion-Tr Smart DC-DC Charger Isolated can´t charge batteries Pylontech, from 2 SLI batteries

Hello everyone, this is my first post on the community.

We are experiencing some problems on a very comples installation.

All is working fine, but our Orion-Tr Smart DC-DC Charger Isolated from 24V on the motorhome, to 48V onlithium Pylontech is not charging. Even when the battery is under 85%.

We like to have the battery full while the motorhome is running.

Any advice?

Please add some screenshots from the overview and the settings of the Orion.

Thanks a lot Matthias.

Pylontech use only 15S packs, your charge voltage is therefore too high. Check the Victron Pylontech manual, i would treat the Orion like an MPPT in this instance

Is the Orion connected over VE.direct to the GX device? Have you set up DVCC?

Do you use a SmartShunt, is the SOC coming from that? 52.6V is fairly well charged for the 15S pack

Thnaks chrigu. We have checked the voltages with the battery data, but will recheck all.

This model is only bluetooth, with no conection.

Thanks a lot.

Ah yeah, i keep forgetting that, im so used to the XS by now. But then at least wire the Orions remote on/off to the pylontechs ATC relay, so that the battery can stop a charge when necessary
