Grid-connected Inverter



Grid-connected inverter is generally divided into photovoltaic grid-connected inverter, wind power grid-connected inverter, Power equipment grid-connected inverter and other power generation equipment grid-connected inverter. The biggest characteristic of grid-connected inverter is the high power and low cost of the system.

In the system of grid-connected inverters, many parallel photovoltaic groups are connected to the DC input of the same set of inverters in general and large photovoltaic power stations. General Power using three-phase IGBT power module, low-power use of field-effect transistors, while using DSP conversion controller to improve the output of the quality of electrical energy, so that it is very close to the sine wave current.
