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.

OEM

Custom Made Solar Products OEM

OEM stands for Original Equipment Manufacturer which is commonly referred to as a company that manufactures and offers parts and accessories of items that are used as components of a product from another company. To sum it up, OEM commonly manufactures specific items on behalf of brands. Though OEM typically operates in the computer and technology industries, it also works in the solar industry.

Factories for White Label Solar Products

In the case of the solar industry, most solar companies work with solar OEMs to build and design their own solar products such as solar panels, cells, modules, etc. OEM becomes their outsourcing partner that helps them in assembling and reproducing their solar products.

Nowadays, a huge number of solar companies, particularly those large solar manufacturing companies, are partnering with outstanding solar OEMs to deliver the best quality solar products to their solar customers. Mainly, the reason is, these solar OEMs help solar manufacturers cut down their production costs since they no longer have to operate their own factories, purchase needed materials and hire labour to produce their solar products.

As a solar manufacturing company, the first thing you need to consider is to find the most reliable solar OEM in the market. One of the biggest perks of the internet these days is you can now easily find these OEMs even in the comfort of your home. With the help of a solar outsourcing marketplace such as SolarFeeds.com, you can easily find the most reliable and right OEM partner for your solar company. Solar outsourcing marketplace helps solar industry professionals gather accurate and timely information about solar including the list of most trusted Solar Original Equipment Manufacturers.

Bulgaria

An Analysis of Bulgaria’s budding solar market

During the forecast period, the Bulgarian solar energy market is expected to grow by more than 2%. Clean and alternative energy sources are believed to reduce carbon emissions primarily as a result of government initiatives. Market growth is expected to be hindered by factors, such as delays in projects, during the forecast period.

In addition, Bulgaria has received EUR 15 million from the European Investment Bank to support climate action projects, which should aid in the growth of the solar power market.

According to estimates, solar installed capacity will increase from 1065 megawatts (MW) in 2019 to 1,180 MW in 2025 with this investment. Moreover, by 2025, the electricity generation is projected to increase to about 1,340 gigawatts hour (GWh).

Bulgaria is expected to grow at a significant rate due to the government’s ongoing efforts and plans for the future.

Bulgaria’s solar equipment production and supply capacity
