solar charge controller

Description

The SDRC controller is designed for solar DC power supply system and solar DC lighting system. MCU and profession software are applied as the control center to fulfill intelligent system control. There are two time setting modes, one time output setting (SDRC serial function) and two times output mode setting. In two times mode, fuzzy control are applied to recognize and adjust the working time to make sure the load only works at night in set time. Characteristics: MCU and professional software are used as the control center to fulfill intelligent system control, along with PWM high efficiency charging way. Boost, recovery and float charging auto work for battery long-life and with temperature compensation. It has high accuracy over discharging control by the discharging rate, over-discharging control voltage modified by the battery discharging rate curve. Our controller has the function of self protection from overload, outside and inside short circuit, reverse connection, thunder and lightning, PV panel reverse current, over charging and discharging etc. During the short circuit and overload protection, no any component will be damaged and need change, including fuse. The LED will indicate the working state of the system in charging, overcharging power full, power low, over-discharging, over load, out short circuit, load on/off and etc. Our products meet the industrial production standard with wide temperature running area **5 degree Celsius to **5 degree Celsius. In order to make sure the control accurate and reliable we use flash memory to save all work control point instead of adjustable resistance to project the control work point from going off as the adjustable resistance value is easily changed by temperature and vibration. And our products are easy to operate, robust in design.
