Grid tie solar inverter
Grid tie solar inverter power system includes PV modules, solar grid tie inverter, and meter and power switchboard. The PV modules convert the solar energy to the DC power, then the grid-connected inverter the DC power to the sine wave AC power which has the same frequency and phase with the grid voltage, and then the AC power FEED-in the grid partly and the other power supply the local loads, it can save any surplus electricity.
Using U.S. TI' DSP chip to control.
using Japan's Mitsubishi IGBT modules, to enhance system reliability.
Maximum Power Point Tracking technology（MPPT), MPPT Max. Efficiency>99%.
Active and passive two kinds of power brown-out detection, to achieve control of anti-island.
