Micro solar inverter is the revolutionary development of the pv industry

In recent years, solar power has become completely modular, that is good news for potential system owner. In ancient times, it is necessary not only to buy a solar cell module, but the battery is good. This greatly increases the cost of your basic system. In 1991, First Solar SMA Solar Technology (the world's largest solar energy equipment company) production of "grid inverter." 

Solar inverter is still the key, all the solar projects. Due to many reasons, Chinese PV industry has been in a cold winter. For this, Chinese government has published many detailed policies and regulations. Chinese PV plants have sprung up. As the main part of the photovoltaic plants, PV inverter, especially the micro inverter, due to their large power amount, longer life and easy installation, have been favored by PV companies.

The DC main transit of micro inverter is to exchange from a single solar module and every single solar panel module has equipped with inverter and converter function. Every module can do Separate current conversion so as called micro inverter. Micro inverter can achieve the maximum MPPT, which is the advantage superior to central inverter. Then, the output power can adjust by the output power monitored by modules to maximize the output power.

As before, many inverter suppliers have to spend much time explaining the advantages of micro inverters and they also recognized, but many customers still beat a retreat due to the policies. With the publishment of national policies, the market of micro inverter has a good market prospect.

Speaking of centralized inverter, many domestic customers have realized of it. The centralized inverter has few advantages in distributed power projects. And the shortcoming, such as small power amount, short life and inconvenient maintenance, will heavily affect the system stability, which may cause the benefit loss of investors.

During the tough time of PV industry, the relevant companies will be like Phoenix Nirvana and the micro inverter may bring the whole industry a rebirth. The time to Ignore the power generation, power plant life, malicious competition from cheap has gone. This is the great fortune of the photovoltaic industry.

Development of new technology can improve the efficiency of solar inverters

The inverter is silent workhorses conversion power, such as solar panels and batteries into usable power supplies. There is a solar cell panel around the pv inverter considerable innovation in recent years, due to a number of solar roofs have begun to move from a single large central inverter to be embedded into a smaller on each panel "micro-inverters." 

Now a year and a half old chip startup Empower Microsystems has been pushing even farther, solar inverter innovation and development of a new low-voltage solar micro-inverter based on its new chip design, it said lower cost, more reliable than those currently on the market efficiency.

Bonanno is a disruptive force very confident inverter technology, known as "universal micro inverters." He believes that it can "replace all solar inverter options, hands down." The key technology of the inverter is on how the chip synchronization, and control power flow in low voltage, and an inverter box design itself.

The company's inverter technology can be connected to a solar panel system, rack or frame, or embedded in a single solar module level. Bonanno said the inverter 5 times more reliable than 5% of high efficiency and cost than traditional "string" inverter, has been used dozens of young and 20%. The potential for lower cost inverter, the entire cost of the solar system may be lower, in addition to the price of solar modules in the recent decline.

Energy storage technology using micro-inverters, solar panels from temporary storage of the DC power supply and AC mains decoupling of. In Empower micro inverter system with a new generation of solid capacitors, this energy storage technology, while other systems are more often used more conventional liquid-filled electrolytic capacitors.

There are a lot of competition in the solar inverter space. Not only have the new micro-inverter companies, such as Enphase Energy Company, and optimization techniques and Tigo Energy's power supply from the same edge of the sun, and it is the same as the traditional SMA inverters giants dominate the market.

The plans to empower micro systems are actually more daring than just replacing the solar inverter. This technique can be applied to energy storage and electric vehicles, as well as Bonanno said the day, they want to enter these markets, but also the road.

Trend of solar power in 2014

For a poor village, solar power companies need to concern about electricity prices. The cheaper, the better, as long as they still can earn some money to run their business. However, the fact is that the electricity generated by solar power plants  is not that cheap due to different reasons, including their solar panel prices, technology research costs, PV inverter prices, land rent costs, employment costs etc.

First off, community solar is big and getting bigger in the US. Also known as solar gardens, community solar allows residents, businesses and government customers to purchase solar energy produced from somewhere other than on their own rooftops. It enables people who are unable to install solar to still benefit from clean energy.

As solar energy was introduced to the world years ago, it has developed quickly and deprived darkness from many power users. In recent years the residential solar PV system has been invented and introduced to homes too. The highlight of its features is the family which has installed the system doesn't need to pay the power bill from the state grid, and can even begin to make money by it. Yet, to install the PV power plant at home, the owner needs to consider his budget for installing the special system. It is not that much, while it requires to pay the price first and use the electricity generated by it later.

Today, no matter in the US or in China, to help people protect the fragile environment, the two countries have subsidized the newly-launched project. The US is promoting the project, so is China, where more and more solar panel and solar inverter companies and factories have been built to manufacture the components that such a system needs.

The US Department of Energy announced that Clean Energy Collective, a specialist in community solar, will receive a $700,000 SunShot cooperative award to develop and implement a National Community Solar Platform. Undoubtedly we will hear more about community solar as it is embraced by more states and municipalities around the world.

Energy storage has not been so much of a trend as it has been a technology in need of useful solutions. At SPI last week we started to see some exciting movement in this direction. GS Battery, with manufacturing facilities in Roswell, Georgia, was showing a storage system housed in a weather-proof enclosure. Not only did the enclosure contain batteries, inverter, charge controller and cooling system, but hanging off the side is a car charger. If foot traffic to a booth is any indication of a hot solution, GS Battery just may have a winner.

Industrial grid-tied solar inverters

Grid Tie Inverters that are available on the market today use a number of different technologies. The inverters may use the newer high-frequency transformers, conventional low-frequency transformers, or no transformer. Instead of converting direct current directly to 120 or 240 volts AC, high-frequency transformers employ a computerized multi-step process that involves converting the power to high-frequency AC and then back to DC and then to the final AC output voltage.

Solar grid-tie inverters are 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 will shut down to prevent the energy it produces from harming any line workers who are sent to fix the power grid.

Many solar inverters are designed to be connected to a utility grid, and will not operate when they do not detect the presence of the grid. They contain special circuitry to precisely match the voltage and frequency of the grid.

Historically, there have been concerns about having transformerless electrical systems feed into the public utility grid. The concerns stem from the fact that there is a lack of galvanic isolation between the DC and AC circuits, which could allow the passage of dangerous DC faults to be transmitted to the AC side. Since 2005, the NFPA's NEC allows transformerless inverters. The VDE 0126-1-1 and IEC 6210 also have been amended to allow and define the safety mechanisms needed for such systems.
