This’s a power electronic device was created by the combination of AC-DC, DC-DC and DC-AC based on microprocessor controller technology and modern switching.
The solar system currently in use functions are divided into three main types:
1. Off Grid solar power system(independent of the grid): It’s a combination of wind / solar charge with True sine wave inverter and battery storage system to provide power to the load ussing 220VAC / 50Hz in places without electricity. This system is good for devices as TV, video, music, lights, fans, refrigerators, pumps, etc. The Off Grid solar power system AST is often used for places without electricity as islands, mountains, desert and etc
2. On grid solar power system - Grid Tie Solar Inverter: It’s a device that converters DC power from Solar (or wind power) to 220VAC/50Hz directly to the national grid without using the battery to store. On grid solar power system’s the highest development of the solar system has been widely used in developing countries all over the world because it has the superior sustainability and efficiency and environmentally friendly. These systems are suitable for installation in the city residential neighborhoods, large consumption electricity centers such as industrial parks, factories, supermarkets, service and etc
3. Grid Tie Solar Inverter with backup: It’s a unique combination by engineers of Viet Linh - AST company design combines the Off Grid solar power system with On grid solar power system - a UPS smart, sophisticated way of exploiting the maximum power and efficiency from the sun in the particular circumstances of Vietnam today.
