Demin Power
1 / 5
Solar power is generated via a solar panel array that converts solar energy into direct current (DC) electricity to be stored inside a battery bank. A complete solar power system typically consists of solar panels, a solar charge controller, a battery bank, an inverter, and AC loads. In the presence of sunlight, the solar panels generate electricity to charge the battery bank; during the absence of light, the battery supplies stored energy to the load through the system.
The solar charge controller adopts a step-by-step current-limiting charging method. It automatically controls the turn-on or cut-off of the multi-channel solar panels based on the voltage variations of the battery bank. This mechanism makes optimal use of solar energy resources while safeguarding the battery bank against overcharging.

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.
