Schubart BMS communication with Sunsynk


Recommended Posts

The system is running fairly well at the moment but I would like the BMS to communicate and show accurate SoC.

Is it possible to connect my Schubart batteries to a Sunsynk 8kW Hybrid inverter and if so how?

I have 4 x 4kWhp batteries connected in parallel. The batteries each have one RS232 (RJ11/12) port and only one RS485 (RJ45) port.

According to the Engrish manual (https://www.lithiumpowerbattery.co.za/wp-content/uploads/2021/04/48V-4KWP-User-Manual.pdf), only the RS232 can be used for communicating BMS info to the inverter and the RS485 can communicate slave to master info between batteries.

Has anyone dealt with this before or know how I would be able to do this?
