The built-in maximum power point tracking engine (MPPT) can better capture changes in lighting, and it can work even in rainy weather. It can maximize the capture and collection of sunlight. The inverter is compatible with a variety of conventional solar panels with an open circuit voltage of 22~60V, and the panel can exert its best performance through technical means. The power output mode of us Micro-Inverter is reverse transmission technology, which supplies power to the load first, and then uploads the excess power to the local power grid. Its conversion efficiency is as high as 95%. The product has multiple national invention and appearance patents , And has CE, CEC, INMETOR and other regional and national product certification. Grid-connected system The biggest feature of the photovoltaic grid-connected system is that the DC power generated by the photovoltaic array is converted into AC power that meets the requirements of the commercial power grid through the grid-connected inverter, and then directly connected to the commercial power grid. The power generated by the panel array in the grid-connected system is preferentially supplied to the AC At the load side, excess power is fed back to the grid. On rainy days or nights, when the photovoltaic array does not generate electrical energy or the generated electrical energy cannot meet the load demand, it is powered by the grid. Because the electric energy is directly input into the power grid, the configuration of the storage battery is eliminated, the process of storage and release of the storage battery is eliminated, and the power generated by the PV square array can be fully utilized to reduce the energy loss and reduce the cost of the system. However, a dedicated grid-connected inverter is required in the system to ensure that the output power meets the requirements of the grid power for voltage, frequency and other indicators. Because of the inverter efficiency, there will still be some energy loss.
