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.

Distributors

Solar Products Distributors

Distributors are those companies working as big warehouses that served as the middlemen between the consumer/customer and the manufacturer. Typically, in distribution, a company is handling the sourcing, stocking and logistics but nowadays they are also helping manufacturers in product designing and solving other business conflicts. 

Aside from other industries, distributors also play a vital role in the solar industry. Solar distributors become long-term partners of solar manufacturing companies and even solar contractors. They are not only serving as warehouse facilities but partners that also provide strategic solutions to help solar companies achieve their desired outcomes. Solar distributors assist solar manufacturing companies by storing. handling and shipping their solar products to their buyers. On the other hand, they help solar contractor companies in outsourcing high-quality solar products. 

These solar distributors are the ones who deal with homeowners who want to go solar, businesses that work with the solar industry and solar installers who offer solar system services to both residential and commercial customers. But on top of that, the solar distributor’s main role is to maintain its commitment to outsourcing and handling high-quality products and delivering them to customers at a good value. 

Up to these days, many solar distributors have been operating and helping many solar companies in distributing their products. So, if you are looking for the most trusted and reliable solar distributor, you can easily find one by checking out solar outsourcing companies that provide easy access to reliable information, news, data and a list of solar suppliers and distributors near you.

Portugal

An Analysis of Portugal’s budding solar market

During the forecast period 2020-2025, it is expected that the solar market in Portugal will grow at an annual rate of more than 8 %. Rising energy demand, efforts to reduce our reliance on fossil fuels, and declining costs of solar PV and associated systems are among the primary drivers of the market.

The solar energy market is also driven by factors such as rising demand for renewable energy, rising investments in solar farms, and government policies. In the coming years, the market for wind energy will likely be restrained by the increasing adoption of an alternate clean power source like the wind.

The Portugal solar market is expected to grow at a significant rate due to ongoing efforts by the Portuguese Government and their future policies.
