MaySun 1200W Micro Inverter

The Solar Grid Tie Micro Inverter is generally referred to as the inverter with a power of less than 1500 watts in the photovoltaic power generation system. The tiny photovoltaic grid-connected inverter is the complete name. The term “micro” alludes to a conventional centralized inverter. Traditionally, a photovoltaic inverter generates direct current (dc) by connecting all of the PV cells in parallel with the sun’s rays. This dc is then sent through an inverter to ac inverters that are connected to the electrical grid; the micro inverter inverts each component. Its benefit is that each component can have independent MPPT control, which greatly increases overall efficiency. However, it also eliminates the need for some dc high voltage apparatus, centralized inverters, the barrel effect, poor light quality, and other issues.

Features of MaySun 1200W Micro Inverter

  •  MPPT(maximum power point tracking), effectively tracks and locks the maximum power output of solar panels.
  •  When the inverter tracks the maximum power point of the solar panel, it will automatically be locked and with stable output.
  •  4 independent MPPT(MPPT).
  •  standard MC4 input port, easy and safe installation.
  • Integration AC output port.
  •    Pure sine wave output.
  •  anti-islanding protection function: The inverter will automatically stop output when the utility grid is off or at fault.
  •  Over-temperature protection, short current protection, and overload protection.
  • IP65 waterproof function.

Applications of MaySun 1200W Micro Inverter

  • Provide clean and environmentally friendly energy for household electricity
  • Shopping malls, factories, etc., convert the solar energy collected by solar panels into alternating current for commercial electricity
  • Agriculture, e.g. powering irrigation systems and livestock houses
  • Power support for people who use electrical appliances
  • In the road lighting system of municipal engineering
  • Convert solar energy into electricity for lighting, to achieve the purpose of energy saving and emission reduction.
