LEES is an industry-leading power conversion system that provides reliable, efficient, and cost-effective solutions for a wide range of applications. It offers a variety of power solutions, including power supplies, converters, and inverters, to meet the needs of any project.
Friendly man-machine operation interface; convenient and practical operation and with the function of remote data transmission at the background.
Support the grid-connected and off-grid operation and cooperate with STS to realize automatic and seamless switching between grid-connected and off-grid status to ensure continuity of load power supply.
It can be adapted to a variety of batteries and implement different charging and discharging strategies for different batteries.
The power factor can be adjusted arbitrarily, which can realize independent control of active power and reactive power to meet different load requirements.
Modularization and string input design are adopted to reduce the series and parallel connection of batteries, which is beneficial to utilization of cascade batteries and improve system stability, which is convenient for installation and maintenance and for capacity expansion.
