I had a Victron Multiplus II based Hybrid Inverter, Let me know if someone tested with Deye batteries.
Which Deye battery exactly? Deye is not on the Victron battery compatibility list, but that doesn’t mean it will not work. Most 48V batteries that use the CANbus standard comms should work with Victron.
