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.

Wholesalers

Solar Products Wholesalers 

Wholesaling refers to buying some products or goods directly from its manufacturer usually at a discount and then reselling it to the retailers for a comparatively higher cost than the original. Basically, wholesalers handle products and package them in small quantities and then sell them to retail customers, either for commercial or personal use. 

Many industries have wholesalers, and that will not skip the solar industries. Nowadays, many solar wholesale stores/firms are operating across the globe, making it much easier for retailers to go solar. Sometimes retailers find it hard to reach direct manufacturers of solar products because some companies do not have their solar stores/shops in public, with that they are not also offering solar products per piece. Through wholesale solar stores/shops, these individuals can easily buy the solar products that they need to replace or maintain their solar systems. 

If you are in need of solar product suppliers for an individual purpose, you may visit some solar outsourcing marketplace to get an updated list of solar wholesalers near your location. There are many solar platforms that provide enough information and data about the solar industry in your region, including all the reliable solar wholesalers in town.

Romania

An Analysis of Romania’s budding Solar Market

In the forecast period of 2020-2025, the Romanian solar energy market is expected to grow at a CAGR of 10%. A major reason why solar power costs have come down over the last few years is because governments and private institutions have taken initiatives to promote research and development in this field at an international level. The cost reduction has made solar technology more accessible, especially solar PV technology.

Growing electricity demand is another major factor contributing to the growth of the market. In the forecast period, the Romanian solar energy market will be constrained by the high investment costs in the early stages of projects and the long investment return periods.
