Solar MD SS4074 7.4kWh Lithium Battery

R49,680.00 incl Vat

Solar MD SS4074 7.4kWh Lithium Battery

The SS4074 relies on lithium Iron-Phosphate battery for streamlined energy storage. You can use 1 to 30 batteries on the wall during the setup. The Solar MD 7.4kWh features different storage capacities according to user requirements. We can increase capacity through the parallel connection of the batteries. This will enable you to use from 7.4kWh to 222kWh setup.

Multicoloured Multipurpose Button

Solar MD SS4074 7.4kWh Lithium Battery

  • The new Solar MD Multipurpose button has an extended functionality in combination with the BMS-EX 3. They can use the Multipurpose Button to execute 6 pre-defined functions and a shutdown instruction.
  • It is combined with the 6 level Indicator LEDs on BMS-EX v3. The user can choose between each function by holding the button until the LEDs count to 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. It also allows mixed combinations when a combination of multiple batteries with BMS-EX 3 are used. The user can change the preferred stage by logging into their mypower24 Energy Portal and going to the battery settings.
  • When this state has been selected, the button, in effect, will show a static illumination in a colour based on the state of charge.
    From RED at 0% SoC (State of Charge) to GREEN at 100% state of charge.
