SOLARMEX solar-energy photovoltaic power adopts pure high frequency switch mode, zero voltage ZVS soft switch technology, high-performance Motorola one-chip computer. The digital and imitation mixed technology can make the primary step-up, and the advanced circuit modulated with SPWM of the wave shape, with high efficiency, small bulk, and good reliance, and high security. It is widely used in the families, cars, ships, regions where the blackout and shortage of power often take place, tasks for mobile electric apparatus, communication equipment, the station of transmitters, and so on. Solar-energy photovoltaic power is not particular about load, so it can be connected to perceptual load such as fluorescent lamps, motors, refrigerators, ice boxes, electric fans, high powered engines and air conditioners. It has functions as follows: low-voltage protection, in the process of the input of direct current, output overload protection, short circuit protection, electric leakage protection, lightning proof function, complete electric segregation protection in the process of the input of direct current, and output of the interchange, and so on.
