Grid Tie Inverters

Buy Wholesale Grid-Tie Inverters for PV Systems? 

Simply put, a grid-tie inverter converts direct current (DC) into alternating current (AC) suitable for injecting into an electrical power grid, normally 120 V RMS at 60 Hz or 240 V RMS at 50 Hz. Grid-tie inverters are used between local electrical power generators: solar panels, wind turbines, hydroelectric, and the grid.  To inject electrical power efficiently and safely into the grid, grid-tie inverters must accurately match the voltage and phase of the grid sine wave AC waveform. 

How Does a Grid-Tie Inverter Operate?

Grid-tie inverters convert DC electrical power into AC power that is suitable for injecting into the electric utility company grid. In order to achieve this, the inverter must match the phase of the grid and maintain the output voltage slightly higher than the grid voltage at any instant.  A high-quality modern grid-tie inverter has a fixed unity power factor, which means its output voltage and current are perfectly lined up, and its phase angle is within 1 degree of the AC power grid. Additionally, the inverter has an onboard computer that senses the current AC grid waveform and outputs a voltage to correspond with the grid. However, supplying reactive power to the grid might be necessary to keep the voltage in the local grid inside allowed limitations. Otherwise, in a grid segment, with considerable power from renewable sources, voltage levels might rise too much at times of high production (i.e. around noon for solar panels).  Furthermore, grid-tie inverters are also designed to quickly disconnect from the grid if the utility grid goes down. This is an NEC requirement that ensures that in the event of a blackout, the grid-tie inverter shuts down to prevent the energy it transfers from harming any line workers who are sent to fix the power grid. 

 Types of Grid-Tie Inverters

Grid-tie inverters include conventional low-frequency types with transformer coupling, newer high-frequency types, also with transformer coupling, and transformerless types. Instead of converting direct current directly into AC suitable for the grid, high-frequency transformer types use a computer process to convert the power to a high-frequency and then back to DC and then to the final AC output voltage suitable for the grid.  Meanwhile, transformerless inverters, which are popular in Europe, are lighter, smaller, and more efficient than inverters with transformers. However, that said, transformerless inverters have been slow to enter the U.S. market because of concerns that transformerless inverters, which do not have galvanic isolation between the DC side and grid, could inject dangerous DC voltages and currents into the grid under fault conditions.

Manufacturers

In the simplest terms, manufacturing is the process of producing actual goods or items/products through the use of raw materials, human labour, use of machinery, tools and other processes such as chemical formulation. This process usually starts with product designing and raw material selection, turning them into an actual product output. 

Solar Products Manufacturers and Factories

In terms of solar, manufacturing encompasses the fabrication or production of materials across the solar market chain. The most common product being manufactured by solar companies are the solar photovoltaic (PV) panels, which are made with several subcomponents such as solar wafers, cells, glass, back sheets, and frames. Before a solar panel comes into life, it will undergo a lot of processes, from designing, modelling, choosing what raw materials to use and then assembling them all to make the final product.

More Than Just Solar Panels

Aside from the solar panels, solar companies have many other manufactured products that are required to make solar energy systems work smoothly, like solar inverters, batteries, combiner boxes, and racking and tracking structures.

Having a solar manufacturing sector makes a big difference in supplying affordable solar energy in different areas. Aside from maintaining the rising domestic and global demand for cleaner and renewable energy, they also help the economy grow, particularly the solar industry. If you are in search of a reliable solar manufacturing company, checking out our solar outsourcing company, SolarFeeds, would help you get easy access to reliable information, news, data and a list of solar manufacturers that can help you with solar products.

Czech Republic

Solar Market Outlook in Czech Republic

In the 2021 Solar Conference, Industry and Trade Minister Karel Havlicek reveals that the future is bright for the solar energy market in Czech Republic. The country plans to move away from coal as its main power source and they are looking at renewable sources as a viable option for replacement.

It’s not just the government that is pushing for solar energy, the private sector also agrees on the importance of switching to solar in Czech Republic. This is fueled by the European Union’s green energy targets and the country believes that the solar industry is poised to play a vital role in meeting that target.

In Czech Republic, in particular, the solar industry is experiencing a massive growth period. There are more households and businesses that have installed solar roof panels. 

Czech Republic held a 19% share in renewable energy for electricity generation. They are expected to increase the share to 22% by 2030. 

Solar Energy Supply Capacity in Czech Republic

There is a long list of solar energy equipment manufacturers and suppliers in Czech Republic. This makes it possible for the country to have a high share of the renewable energy market in Europe and worldwide. 

In fact, some of the biggest manufacturers and producers of solar panels and technology are serving the Czech market.

Top 8 Major Seaports & its Logistics

Czech Republic is a land-locked country. However, it has sufficient access to the sea through its ports that facilitate logistics companies moving goods and other equipment. 

The main ports in Czech Republic are: 

• Decin Port
• Usti Nad Labem Port
• Port Praha Radotin
• Port of Kolin
• Port Melnik

When transporting solar equipment from top manufacturers in Czech Republic and other parts of the world, there are also several logistics companies to help with this such as the following:

• Vit Logistics
• Rail Cargo Logistics
• GEFCO Trucking Company
