Precharge with Tyco relays


  • Hi, I need some help.

    Setup:

    REC Active BMS

    Tyco relays

    Pre charge unit

    I have a Victron Multiplus that I want to connect a Tyco relay that shall open at overvoltage, I also have a Pre charge unit.

    How shall I connect this Tyco relay to the BMS and Precharge unit?

    Was thinking to use the RELAY CH from the BMS, but were shall I cannot the wires to teh Pre charge and the Tyco relay?

     

    Then I want to conncet another Tyco relay on another charge bus coming from solar and a DC-DC charger to also open on Overvoltage, do I need any Precharge unit for thiss? Please suggest any relay from BMS to be used here.

     

    Then a Third Tyco relay that shall open on Undervoltage on the Load bus, any pre charge needed for this?

    Please suggest what relay from BMS to be used here.
