Demin Power
1 / 5
Solar power is the generation effect of a solar panel pack that converts solar energy into direct current energy and stores it in a battery. A solar power supply system consists of solar panels, solar charge controllers, batteries, inverters, AC loads, etc. The solar panels convert solar energy into electricity in the presence of light while charging the battery; in the absence of light, the battery supplies power to the load.
The solar charging controller adopts a step-by-step current-limiting charging method. It automatically controls the activation or cut-off of the multi-channel solar panels according to the changing trend of voltage at the battery bank end. This makes full use of solar energy resources and guarantees the safe and reliable operation of the battery bank.

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.
