The device collects data from battery BMS via RS485 and transmits it to the inverter through the CAN bus. Supports up to 48 batteries on 3 independent buses and allows for the connection of different types of batteries in one system. Compatibility with BMS DEYE, Felicity, VAMI, PACE, BSL, NPP, SOK, and JK BMS ensures wide usability. Web monitoring in real-time provides an overview of the battery status, alarms, and operational values.

Security and clarity every second

Reliable operation begins with correct wiring. Clearly marked connectors and adherence to polarity help protect the device and the connected BMS from damage. Designed for batteries with their own BMS protection functions that ensure protection against overvoltage, undervoltage, overcurrent, and short circuit. It is advisable to reserve a fixed IP address for the device in the router (DHCP reservation based on MAC).

Flexible connection for photovoltaic systems

Designed for low-voltage battery systems (Low Voltage) in photovoltaic installations. The device can be powered via a 12 V DC terminal from the inverter (if it is a DEYE product) or using USB-C power, which is not included in the package. More information and options for the device can be found in the manual.
