Hi everyone,

I have been using Crown Xavier II 5.6kW inverter for my home setup for about 1.5 years now. It's been working great but I want to upgrade my battery to LiFePO4

The down side is this inverter only has USB/RS232 ports and doesn't support dedicated RS485/CAN for BMS communication. Plus I think Pylontech and other major brands void their warranty if the battery is used without BMS.

Is there any external workaround to get the BMS communication to my current setup?

Does anyone know any reliable solar dealers in Rwp/Isb that accept used inverters as trade-ins for a new BMS-supported hybrid inverter?

Thanks for any advice!
