Features
Product testing and certification
The PCS-9563 inverter has passed the LVRT field test by SGEPRI and Qinghai Electric Power Research Institute in Qinghai PV Power Station. Furthermore, the inverter of PCS- 9563 has passed the test and got the certificates from TUV, CQC and NESC.
High reliable and long-life system design
The primary/secondary components of the inverter have good quality and long operation life. The component selection, power design, and heat dissipation design are all based on high altitude and extreme adverse conditions with margin to ensure the reliable system operation and working life. The inverter adopts modular design to ease installation and maintenance, including IGBT module and other major equipment. The large capacity IGBT modules are used to reduce parallel connections and increase equipment reliability. The optical triggering method has strong anti-interference capability and the patented heat dissipation scheme is employed to achieve high reliability and efficiency.
High-performance and reliable control devices
The control & protection devices features well performance, high reliability and mature hardware/software technologies. The core controller is equipped with the most advanced floating controller which has advantages of high main frequency, large memory capacity, and high computation and control accuracy. The control system fully supports IEC61850 and IEC60870-5-103 etc. The equipment uses integrated front panels and enclosed rack that it can protect against dust and ensure the safe and reliable operation of control system during the service life of PV power station.
High power quality
The grid-connection power quality controlled by PCS-9563 is far higher than that defined in the relevant codes and standards. In the certified test by CGC-SOLAR, both the total harmonic distortion of voltage (Uthd) and current (Ithd) are smaller than 2%, the voltage on connected network is even smaller than 1% at rated power.
Complete and reliable protection functions
PCS-9563 system has inherent protection for IGBT modules by detecting abnormal dv/dt and di/dt in IGBT and blocking the triggering pulse instantly. As a result, it can ensure safe and reliable operation or rapid and safe shutdown even in severe environment.
