The development prospects of solar inverter uses and processes

Solar AC power generation system consists of solar panels, charge controllers, inverters and batteries composed. Mainly composed of electronic components, it does not involve machinery parts, thus generating equipment is extremely refined, reliable, stable, long life, easy installation and maintenance. Compared with the conventional thermal power system, solar power system in addition to polluting emissions, but also has short construction period and can be used roofing advantage. Wherein the with bypass inverter is a key component of the entire solar system. Because of the direct solar energy output are generally 12VDC, 24VDC, 48VDC. If you want to 220VAC to provide electrical power, solar power system needs to be issued by the DC energy into AC power, this time on the need to use an inverter. In addition, it can be a variable DC output of photovoltaic cells to convert into a clean sinusoidal current at 50 or 60Hz, it is also ideal for providing power to the commercial power grid or local grid. With the development of the solar PV market, solar inverter market will inevitably bring a new spring.
Generally speaking, there are step-up transformer and two types of isolation transformer is applied in the 5000w inverter charger electronic transformers. Since the input DC voltage than AC output voltage level is higher, but the solar panels provide input source voltage is usually not so high, so the system to the AC output side of the step-up transformers to boost voltage. At the same time, both sides need to isolate the circuit transformer isolation to prevent flow AC DC side, improved circuit protection, but also increase the safety of users.
Power inverter can be divided by converting frequency conversion and high-frequency transformation. Frequency transformation is the use of discrete devices or manifold generate 50Hz square wave signal, and then use the signal to push the power switch, the use of frequency step-up transformer to generate 220V AC. As a result of frequency transformer, bulky, heavy, high prices, currently used in large-scale solar photovoltaic power plants. But as the technology matures and the magnetic power MOSFET improving the quality, high-frequency inverter transform it to market. High-frequency 12v car inverter is converted by high-frequency DC / DC conversion technology, the first low-voltage DC power to high-frequency low-voltage AC, after the pulse transformer and then rectified high voltage DC boost.
