Suzhou Menhai Microelectronics Technology, also known as Gate-sea Microelectronics, is a professional integrated circuit design company established on July 2, 2018. The firm is focused on the research, development, and sales of MCU/SOC chips, providing clients with comprehensive system-level solutions. The company was founded by Lin Xiongxin, a serial entrepreneur who serves as CEO. Before establishing Menhai, Lin was the technical director at Suzhou Guoxin, where he led the development of over 30 distinct chip designs for the information security and automotive electronics sectors, achieving shipments of several hundred million units. The core leadership team brings nearly two decades of semiconductor industry experience to the venture.

Menhai Microelectronics operates in the energy Internet of Things (IoT) market, with a specific focus on the smart grid and new energy photovoltaic (PV) sectors. Its business model involves designing and selling specialized chips and modules to a domestic and international client base. The company generates revenue through the sale of its hardware products and integrated solutions. The product portfolio includes high-performance single/dual-mode broadband power line carrier (HPLC) chips, Wi-SUN small wireless chips, and component-level power electronics for the distributed PV market, such as rapid shutdown devices and smart optimizers. One of its key products, the independently developed HPLC chip, features proprietary noise suppression and intelligent adaptive technology, which addresses communication instability issues over power lines. These products are widely applied in smart grids, power distribution networks, orderly charging systems for electric vehicles, and photovoltaic installations.

The company has secured significant financial backing to fuel its growth and product development. In July 2022, it closed a Series A funding round worth tens of millions of RMB. This was followed by Series B and B+ rounds totaling over 100 million RMB and a C round of financing for a similar amount in April 2024, with funds designated for enhancing PV product research and market expansion.
