Daly Communication Boards [comboards] – New Versions and Features
Daly has added three new Comboard communication boards.
These boards are designed to communicate with BMS inverters from the K-, M-, S-Series, 100Balance and BMS CAN/RS485 series of previous versions.
The boards are required for communication with the inverter and for mutual communication between BMS in parallel connected energy banks. The boards have a built-in temperature probe, providing information on the ambient temperature.
NOTE: all boards look identical, but differ in software. You should order a board that is compatible with your BMS model.
In energy storare banks operating in parallel, all BMS and boards must be of the same type. For example, it is not possible to establish communication between a energy bank with a BMS M-Series and a bank equipped with an older BMS CAN/RS485.
