Reactive Power Compensation and Harmonic Control

Chennuo Electric independently develops and produces active power filters (APF) and static VAR generators (SVG). This system monitors high-voltage line parameters such as voltage, current, reactive power, and power factor in real time. Based on these parameters, it provides dynamic compensation for the high-voltage grid, playing a significant role in improving line power factor and voltage, reducing line losses, and enhancing grid power quality.

Battery Energy Storage System

Household energy storage systems allow users to store their own electricity and reduce their dependence on traditional power grids. Chennuo offers a variety of specifications and configurations, including stackable energy storage and wall-mounted energy storage. Commercial energy storage systems are capable of storing and releasing large amounts of electrical energy. They can not only provide energy support during peak hours, but also serve as a backup power source during power outages. They are suitable for factories, office buildings, electric vehicle charging stations, etc. In areas with limited power supply, energy storage cabinets can solve problems such as power shortages and frequent power outages, and realize intelligent and safe power consumption of internal power supplies and loads. It can not only smoothly connect to the main power grid, but also operate independently, meeting or improving users' requirements for power quality, reliability, and safety.

EV Charging

Our EV charging stations cover charging needs in different scenarios. 7kW and 14kW AC charging stations can meet the needs of home charging stations and are safe and reliable with multiple protection features. 60kW to 480kW integrated DC charging stations enable high-power fast charging and are generally used in commercial charging stations. They are highly reliable and easy to maintain. 360kW to 960kW group-controlled DC charging systems enable dynamic power distribution and are highly flexible, intelligent, and scalable.
