Product Description
  • Energy flows bi-directionally, i.e. it can discharge from the battery side to the DC grid or charge from the DC grid side to the battery.
  • Fully automatic protection functions for overheating, overload, short circuit, overcurrent, etc.
  • Selection of original imported power devices.
  • Fully digital circuit design.
  • All the chips are industrial grade and can operate normally in cold, high temperature and humid environment.
  • The main circuit adopts DSP chip produced by TI of America, Infineon IGBT module and Infineon movement for driving and protection, which is safe and reliable.
  • The output is automatically synchronized with the grid, the current harmonic content is low, and there is no pollution and impact on the grid.
  • Closed loop control of grid connected current, controllable and adjustable.
  • Wide input voltage range, suitable for different occasions.
  • The system has all-round power protection scheme and perfect self-test and protection function. In case of system failure, it will stop working.
  • The circuit structure is compact and the maximum efficiency ≥ 96%.
  • Protection level can be customized according to the user's needs.
  • Provide Ethernet interface, standard Modbus TCP communication protocol.

COMPANY PROFILE
Company Growth
The company was established in 2004 and acquired two registered trademarks in the same year. After five years of accumulation in 2009, the company gradually matured steadily. The company purchased factory buildings with independent property rights, and the company relocated to start a new journey. In 2012, the Ministry of Foreign Trade was established to open up markets and begin to expand foreign markets. In 2015, the company achieved rapid development, with 2 invention patents, 6 utility model patents, 1 appearance patents, obtained the "high-tech enterprise certificate" recognition, and obtained the ISO 9001 quality management system certification. In 2018, the company continued to innovate, with four invention patents, six utility model patents, and two software registration rights, and again successfully recognized high-tech enterprises. On July 10, 2019, it passed the certification of intellectual property management system. In 2020, three patents for invention and six patents for utility models were applied for.
