Product Description

3-phases 380V on grid solar invertor 50kw 


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 .The AC power FEED-in the grid partly and the other power supply the local loads.

 

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.
