Ⅰ. Product overview MPPT solar controller is designed for solar power system design; equipment can not only efficiently transfer issued by the solar panels to recharge the battery power, but also provides a powerful control functions. Features: The controller is characterized by intelligent adjustment of the operating voltage solar panels, solar panel always working at the VA characteristic curve of the maximum power point. More common, solar controller, solar panels for power generation increased utilization of 10-30%! The controller uses solar panels for intelligent charging of the battery. In the solar panel power than the battery storage capacity, the control system automatically cut off the charge, thus ensuring optimum battery charging features, making full use of electricity. As the battery can only withstand a certain degree of charge current and float voltage, over current and over-voltage charging the battery will cause serious damage. The controller battery charge grams of real-time detection voltage and charging current, and by controlling the charge current to limit the photovoltaic battery charging voltage and charging current to ensure that both the battery is full, it will not be damaged. To increase of the battery service life. Digital intelligent control ensures excellent performance and stability of the controller principle：Figure 2 shows a typical 12V battery, solar charging system VA characteristic curve: use the normal solar controller：the solar panel working pint at A ，the solar panel voltage higher than the battery voltage a little. Charging voltage UA=13.2V, Charging current IA=9.8A Charging power PA=13.2*9.8=129.36w Area is ①＋③ Use the MPPT solar controller：the solar panel working pint at B，the working voltage much higher than the battery voltage. Charging voltage UB=18.4V, Charging current IB=9.3A Charging power PB=18.4*9.3=171.12w Area is ①＋② compare：the latter than the former charge efficiency increase as: △ P/ PA =（PB— PA）/ PA＝ 32.3%，As the solar panels produced different changes in solar illumination, temperature change, the majority of the controller efficiency factor, the actual available about the rate of increase between 10-30%. The controller has perfect protection features, including: lightning, solar anti-anti-charge, battery reverse polarity and open circuit protection.



Professional digital intelligent control.

Perfect protection function: * Solar prevent reverse charge, at night or the light is bad, the battery voltage may be higher than the solar array voltage. The controller can prevent the generation of solar cells reverse battery charge * Reverse battery protection, Reversed when the batteries have a huge transient current of the circuit fuse in the fuse will automatically make the battery circuit is disconnected, so as to effectively protect the battery and the device. * Battery open circuit protection, Long-term use, the battery open-circuit may occur, or poor contact. The controller in the battery open-circuit protection device itself will not be damaged. * Overload protection, the controller will automatically cut off the circuit.

Ⅴ. Operating The installation of the controller personnel must is a certain electrical knowledge and experience and technical personnel, and strictly according to the instructions of the provisions of the manner and steps!!!!! Operating Mppt controller parts PV panels installed, after the completion of construction of the external circuit, the following should be safe and reliable in order to carry out the connection and operating system components. Installation: ready-related tools and cables, the proposed matching the right cable, ensure that the current density is less than 2A per square millimeter, so that will help reduce the line pressure drop, Recommended: 30A with 25 mm of cable, the controller will be mounted in a vertical plane, in order to ensure good thermal, please hold 10 mm space in the controller up and down. 1, the solid battery positive and negative terminals connected to the pole on "+","-"; 2, the solar panels are firmly connected to the negative battery terminal on the board "+","-" pole; 3, the load is firmly connected to the positive and negative load of the corresponding terminals. (Demolition: To prevent accidents, remove the connection, remove the solar panels first, then remove the battery connection.)
