50A solar charge controller
The controller is designed for solar power supply system, solar DC street lamp system, And use the intelligent controller of special computer chips . Use a key type light touch switch, complete all operation and Settings. With short circuit, overload, unique counter-attack joint protection, full of, put automatic shutoff, restores and so on the whole function protective measures，the detailed charging indicator, battery state, load and all kinds of fault indicator. The controller through the computer chip to take sample for relates to the parameters of the battery capacity for the of the battery terminal voltage, the discharge current, ambient temperature, etc. Through the special control model calculation, realize conform to the battery characteristics of the discharge rate, temperature compensation correction of high efficiency, high accuracy control, and adopted the efficient PWM battery charging mode, ensure the battery work in the best state, extend battery life. With a variety of work patterns, output mode choices, satisfy the users' various needs.
The main features：
1,Using MCU and special software, based on the special software of the expert control system, realizes the intelligent optimization SOC control.
2,The temperature compensation adopt external temperature sensor, the control accuracy is higher than the internal temperature sensor.
3,Have the overcharge, discharge, electronic short-circuit, overload protection, unique counter-attack joint protection automatic control; Above the protection are not causing damage to any component, and don't burn the fuse.
4,Adopt the tandem PWM for charging main circuit,make the charging loop voltage is reduce nearly half than use the diode charging circuit.The charging efficiency is higher 3%~6% than the non-PWM, increased the power of time. Enhance the charge of over-discharge recovery, normal direct charge, the float-charge automatically controlled way can make the system has a longer use life.
5,The intuitive LED iuminotron indicates the current battery status, allow users to understand the situation of use.
6,The all control adopt the technical grade chip,can run freely in cold,high temperature,damp environment. At the same time use the crystal oscillator timing control, precise timing control.
7,Using the digital LED display and Settings, a key type operation can complete all Settings, use is very convenient for intuitive.
8,with multi-stage single session load time setting, and multistage load time setting can be set up independently of the double time.
9,double time set adopted fuzzy control automatic identification and according to the actual correction night shut down load time (accurate to points), to ensure the load only at set time to open after the morning before it gets dark.
