Hello,
I Have an Polyontech Batterie connectet. All works fine, but after 6 hours I get the Alarm "low Batterie" What I see is, that the communication via CAN Bus stops. If I reboot the Victron all works fine again for the next Hours. A second problem is that after each Reboot I have the problem that the SMA Inverter connectet via TCP MOD Bus gets offline.
