Achieving a maximum conversion efficiency of 95% with MPPT technology! Reducing charging time and compacting small independent power supplies.

The "WSC Series" is a solar charging module suitable for small independent power supplies (solar power generation and storage systems) that use lithium-ion batteries. By adopting the MPPT method used in mega solar installations, it achieves a high conversion efficiency of over 95% while being compact and lightweight. It enhances charging efficiency under adverse conditions such as rain and cloudy weather, contributing to reduced charging times and miniaturization of the system. Additionally, it is equipped with safety features including overcurrent protection and overheating shutdown functions. With low power consumption, connection and setup tasks for the system can be easily performed according to the type of solar panels and batteries, accommodating a wide range of needs. 【Features】 - Usable with lithium-ion batteries, as well as lead and nickel-hydrogen batteries - Suitable for use in surveillance cameras and measuring instruments with communication functions due to low noise - Available in three models: 20W1A, 50W2A, and 100W8A - Can be introduced at a low cost similar to PWM controllers *For more details, please refer to the materials. Feel free to contact us with any inquiries.
