Company Profile

03/04

Energy storage play an important role in the smart grid. It is widely used in all aspects of power generation, transmission, distribution, and

utilization to achieve peak-shaving and load shifting, suppression of fluctuations, output tracking and scheduling, peak and frequency

modulation, demand management, black start, and demand composite application value such as side response. The continuous progress

of energy storage technology will drive the rapid development of the entire power industry chain and create huge economic value and

social benefits.

Three-level topology, up to 99% conversion efficiency, better power quality

Supports two sets of battery access and independent charge and discharge

management, which is more battery friendly

Key device IP65, strong adaptability to harsh environments such as high

altitude and high temperature

Highly integrated, small footprint, more convenient and efficient transportation,

hoisting, installation,O&M

With PQ, VF, SVG, VSG and other functions, support high/low ride through,

frequency ride through

Fast power dispatch, off-grid operation and "black start", strong grid adaptability

Integrated design Easy to install
