Solar MD SS4144 281Ah 14.4kWh 48V Wall Mount Lithium Battery

The SS4144 relies on Lithium Iron-Phosphate battery for streamlined energy storage. The Solar MD 14.4kWh can increase capacity through the parallel connection and can use 1 to 6 batteries on the wall during the setup enabling use from 14.4kWh to 85.8kWh a setup.

  • The new Solar MD Multipurpose button has an extended functionality in combination with the BMS-EX 1.03. They can use the Multipurpose Button to execute 6 pre-defined functions and a shutdown instruction. It’s combined with the 6 level Indicator LEDs on BMS-EM v10.01. 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-EM v10.01 are used. The user can change the preferred stage by logging into their mypower24 Energy Portal and proceeding to the battery settings.
  • When this state has been selected the button 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.
