Specifications

 

The DC OUT of PV inverts to stable three phase AC supply to load with KM, and feeds the redundant to national grid.

Features
Based on HF chain and parallel operation technology with DSP, several inverter can be parallel operated and run, simplified the design of the power station.
Adopted the IPM module of 5th generation of Mitsubishi, increasing the system efficiency greatly.
Self-optimizing of MPPT, increasing the efficiency of power produce of PV system.
Adopted the software calibration with the DSP, assure the power factor of 100%.
Adopted the technology of initiative frequency offset to detect the island, make the grid protecting safe and reliable.
Large screen of multiple language of LCD display.
Power production and CO2 emission reduction calculation for 5 years
Flexible output setup, suitable to various countries' local regulation
Multiprotection design, make it more safe and reliable
Specialized remote setting and detecting software, make the computer adjusting more intelligently
Wider range of operating temperature of -25~+50º C.
