This project needs to study the CF4 detection method, improve the detection ability of the system, meet the requirements of effectively detecting CF4 gas under the low concentration conditions, and further study the low concentration CF4 gas monitoring technology under the background of high-pressure equipment SF6, soAuthor: Yongtao Chen, Shiling Zhang, Qiang Yao

Integrated PV input string fault detection circuit and PV input arcing fault detection circuit to ensure the safty. High Efficiency. Maximum efficiency of 98.6%, Euro efficiency of 98.1% 3-level technology and enhanced control mechanism to achieve high efficiency over wide load range 2 MPP trackers to achieve higher system

1500V PV Combiner Box. Chint Power 1500V PV combiner box configure with DC SPD, 1500V fuse, and circuit breaker. The smart detection module in the PV combiner box can monitor PV string

The smart detection module in the PV combiner box can monitor PV string current, BUS voltage, device status and failure, etc. The fault alarm and communication functions help users to accurately monitor the PV arrays on time, maximize PV system efficiency,significantly reduce the cost of whole PV system.

For a large-scale grid-tied PV system , it is general to install a DC combining device between the PV arrays and inverters to minimize the cable distance, facilitate maintenance and improve reliability. Chint Power PV combiner box is a highly reliable and practical product to meet CHINA PV industry standard and power electric

With reactive current and power factor detection system, it can ensure accurate control in the full load range and make sure that the power factor can reach over 0.95. With over-voltage inverse time function, it is adaptable to the grid of high voltage. Able to switch over between manual operation and automatic operation

CPS is excited to add the new 36kW three phase string inverter to its product portfolio for North America. The medium power series of grid-tied, transformer-less inverters are cost effective, efficient and flexible modular inverter building blocks for rooftop and large ground-mount solutions.
