The rise of new solar giant, the Great Wall Satcon inverters installed worldwide breakthrough 3GW

Shenzhen Changcheng Electrical Energy Limited (referred to as the Great Wall of Energy) in Shenzhen, held a news conference to formally announce the "Great Wall Satcon pure sine wave inverter installed worldwide breakthrough 3GW". This means that the Great Wall Satcon inverters substantial increase in installed capacity worldwide, as well as brand, channel, marketing, etc. to enhance the comprehensive ability, but also means a new leader in solar inverter is on the rise.

Forefront of technology is king independent

Great Energy is a Fortune 500 company China Electronic Information Industry Group (referred to as China Electronics)'s solar industry backbone enterprises. In the solar inverter industry, with independent research and development, production and sales, technical consulting, engineering, turnkey, engineering design, installation and technical services such as a complete industrial chain, and became the world's second largest, North America's largest utility-scale inverse Transformer manufacturer Satcon most important strategic partner.

Since 2009 began to cooperate with Satcon, Satcon inverters Wall will by virtue of environmental adaptability, full power conversion efficiency, reliability, good technical advantages are exported to Europe, Asia and other countries or regions.

To the inverter core indicators - full power conversion efficiency, for example, the Great Wall Satcon solar power inverter are not lit, load and other restrictions, the entire operating cycle can achieve high efficiency conversion. Its unique patented technology MPPT maximum power point tracking technology and control strategies through advanced control strategies to achieve longer online generation time every day, and through the accurate and rapid solar array maximum power point tracking technology, to maximize conversion , issued by the energy output of the array.

In addition, the Great Wall Satcon inverters are used outdoors chassis design, all built-in AC and DC power distribution cabinet, can be directly arranged in the outdoors, without additional configuration DC cabinet, do not need to set up another equipment room, easy to install, simple, effective conservation construction, civil engineering, HVAC, fire protection and other aspects of the cost and reduce the footprint, reduce the formation of shadowed components, which increased land utilization..

The GaN and SiC will score back to introduce the use of the development trend of pure sine wave inverter

The will after explaining the basic principle of grid tie inverter, analyzing the principle of improve performance by SiC, GaN, and so far grid tie inverter research and development situation of the two kinds of materials.

High pressure and low conduction resistance cannot be both at the same time

The first to introduce the basic principle of grid tie inverter. Power components are usually shut down (as) and open (conducting) using two kinds of condition.

Closed, that is,power inverter must be completely disconnect current voltage required.

About the opened state, required in the case of loss minimum, also is the minimum resistance through the current (voltage).

Closed under Vb components can't maintain the insulation state of voltage is called the breakdown voltage,power inverter or simply referred to as stress.

Closed resistance is closely related to the element size, because be components of resistance per unit area, so the use of indicators on resistance is characterized by RonA (A area).

In general, the higher the pressure, the smaller the conduction resistance, the higher the performance of the pure sine wave inverter, but pressure and reciprocal relationship between conduction resistance.

This is due to the working principle of pure sine wave inverter.

Here in the most simple pure sine wave inverter, schottky barrier diode (SBD) as an example, introduce the pressure relationship with the on resistance (figure 2).

Diode in a closed state is reverse biased condition, semiconductor is in no charge carriers (electrons and holes) run out of state.

Can be in a state of depletion of the semiconductor layer as insulators, shut off the electric current through the layer.
