Multicolored multipurpose button

  • The new Solar MD Multipurpose button has an extended functionality in combination with the BMS-EM v10.01. The Multipurpose Button can be used to directly execute 6 predefined functions and a shutdown instruction. In  combination with the 6 Indication LEDs on BMS-EM v10.01, the user can choose between each function by holding the button until the LEDs count match the number of the function. By releasing the button while moving through the functions, LEDs will start blinking and wait for the user to press the button again within 3 seconds.
  • Advanced indication functionality, allows the user to choose between 5 different states. Mixed combinations are also allowed when a combination of multiple batteries with BMS-EM v10.01 are used. The User can change the preferedstage by logging into his mypower24 Energy Portal and go to the Battery Settings.
  • When this state has been selected, the button shows static illumination in a color based on the state of charge.
    From RED at 0% SoC (State of Charge) to GREEN at 100% state of charge.
