This kind of solar charge controller is special design for small off-grid solar generation system. Appearance is elegant, operations are easy. It also makes the course of which wind generator and solar panels charge to batteries safely and efficiently.

Functions and Feature Ø High efficiency MPPT charging mode Ø Intelligent limiting of batteries max current Batteries maximum capacity could be set through this controller. According to the set maximum capacity, controller could calculate the maximum charging current. Then batteries will be protected. Ø Over-charge , Over-discharge and Over load protections for battery Ø Solar charging manual switch On the controller you can manually set whether using solar charge to battery. Ø LCD Display Multi-level Menu; Intelligent Button Settings By RS232 or RS485 serial interface communication, you could monitor the whole system, storage and analyze data. Program could be upgraded by serial interface. Connect PC and controller by serial interface. You could set the parameters on PC and controller simultaneously. Software is free, easy to operate and no need to be installed.   What is MPPT (Maximum Power Point Tracking) Maximum power point tracking (MPPT) system is an advanced charging technology which can make the solar panel output more power by adjusting the working state of the electrical  module. Due to the nonlinear characteristics of solar array, there is a maximum energy output point (maximum power point) of the array on its curve. The traditional controller (switching charging technology and PWM charging technology) can not maintain the battery charging at this point, so it can not obtain the maximum energy of the battery panel, But the solar controller with MPPT control technology can always track the maximum power point of the array to obtain the maximum energy to charge the battery.   Take the 12V system as an example, because the peak voltage (VPP) of the solar panel is about 17V and the battery voltage is about 12V, when the general charging controller is char
