Grid inverter for microhydro

• Main circuit is using U.S. TI’ DSP chip, Infineon IGBT modules,Infineon‘s driver protection, grid-connected output part adopts isolation transformer, safe and reliable ;
• Using SPWM pulse width modulation,pure sine wave output,automatically synchronized with the grid tracking,power factor close to 1.Low current harmonic content , pollution-free and non-shock to grid;
• Hydro input maximum power tracking technique (MPPT);
• grid-connected inverter’s current closed loop control, control and regulate;
• DC voltage across a wide range of input,adapt to different circumstances demand;
• Frequency disturbance the technical, to achieve control of anti-island;
• A comprehensive power to protect and improve yourself and protect the function.In case of system failure to stop the grid-connected invert ion ;
• Circuit frame compact, ax. Efficiency≥94%;
• Protection class up to IP20 ;
• Optional RS485 communication, Upper machine monitoring, achieve the remote data collection and monitoring ;
