200kW Solar On Grid Inverter for solar panels system
Summarize
PV grid-connected power system includes PV modules, grid-connected 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.
Product advantages：
◆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.
◆with Wide DC input voltage range.
◆EMC priority, Strong anti-interference ability.
◆circuit frame compact, max. Efficiency≥95%.
◆pure sine wave output, automatically synchronized with the grid tracking, power factor close to 1.
◆Fed into the grid mode selectable low frequency transformer or non isolated transformer.
◆Inverter current double closed-loop control, low current harmonic content , pollution-free and non-shock to grid.
◆Perfect protection and alarm functions.
◆big-screen English LCD, perfect display, interface-friendly.
◆A variety of communication interfaces, host computer monitoring, remote data acquisition and monitoring.
