ECO-WORTHY 20A MPPT Solar Charge Controller 12V/24V

Maximum Power Point Tracking solar charge controllers (MPPT) are different than the traditional PWM solar charge controllers in that they are more efficient and in many cases more feature rich. MPPT solar charge controllers allow your solar panels to operate at their optimum power output voltage, improving their performance by as much as 30%. Traditional solar charge controllers reduce the efficiency of one part of your system in order to make it work with another.

  • High-speed MPPT High technology:MPPT with LCD display, efficiency > 99%, Employs a DC converting circuit,conversion efficiency > 96%
