Brief introduction

Series Solar DC power supply is designing for adapting no-electricity areas lighting and mobile phone charger. It can supply the direct current for areas where the electric network can not cover, and supply the environmental energy for lighting and mobile. Series Solar DC power supply can control battery charge from solar, when consumer need use the electricity, it can supply the DC for loading use. It has the functions with anti-polarity, under-voltage protection, over pressurization protection, overload protection and so on. Solar energy has the characteristics with charging high efficiency, high anti-shock, and operation stability, reliability.

Application scope

12V (or 24V) household DC electrical equipment : DC light, DC energy-saving lamps, DC LED lamp, DC TV, DC satellite receiver, MP3, MP4, mobile charging and so on.

 Using place

The place with sunshine can use, especially suit to observation desk in mountain, mariculture, crop farming such electroless remote districts.

 Consist of

Solar DC power supply is consisting of five parts: solar modules, steel frame, connecting cable, the battery and charge/discharge controller integrated machine box. It is concentrated on high reliability, and the power devices have bigger remainder number and high durably. The main frame-box is made by electrolytic zinc steel plate, and it has Unique design, good appearance and convenient to carry.

 Operating introduction

3.1 Front  panel  include  charge  indicator  light,  work  indicator  light  and  battery  low-voltage indicator light; two groups 12VDC output block: one group is terminal output (left “—” right “+”), it’s convenient for the user to use the direct electrical appliance with nonstandard

connector lug. Another group is  5.5 standard output block( the middle is positive,the side

is negative). Besides, there is one group output is 5VDC/1A double U port output block, it supplies the power for mobile charge. The three groups is controlled by the switch one the front board.

3.1.1   The green indicator light instructions the machines work properly.

3.1.2    The blue indicator light indicates the solar energy is charging to the battery.

3.1.3      The red light :The red light indicates the battery is under-voltage, it means the battery voltage has dropped below the allowable working voltage, or although the battery voltage has back up to allowable operating voltage, but in practice the increase is not because of the charged, it's the false increase because the    under-voltage protection cut off the load. Only solar energy charge into the battery and the battery voltage back up to the allowable operating voltage, the red light will extinguish.

3.1.4 The back board has the main switch and solar modules output block (left "—"; right "+").
