Advanced digital isolation technology to improve the reliability of solar inverters

One hundred years of power generation facilities have proven to be stable and reliable source of energy , but these facilities are large and complex , and rising construction costs . Meanwhile, with minimal carbon emissions and environmental impact criteria to run these facilities are also facing great challenges and cost pressures. In contrast , modern photovoltaic (PV) power plant power system as a reasonable alternative , it can provide a lower cost of long-term operation , modular, scalable , efficient , and carbon emissions lower than a centralized power generation facilities lot .

Photovoltaic power generation system consists of several components, such as the conversion of light energy into electrical energy photovoltaic panels , mechanical, electrical connectors, accessories, as well as the solar-generated electricity to the grid essential to the process of solar inverters .

What is a solar PV inverter ? Photovoltaic panels to convert sunlight into direct current , and in order to minimize line losses , and the more long-distance power transmission , must be converted into a DC high voltage alternating current. Solar PV inverter can achieve the above DC to AC conversion, photovoltaic systems of all the most critical part. However , this is only the PV inverter is one of the key features .

PV inverter disconnects from the grid also has the ability to prevent PV system is not connected to the public service system to provide power ; That is, if the grid is disconnected during the online status of the inverter to maintain , or to unreliable connections providing power, photovoltaic power generation system can cause feeding local public service system transformers and wires in the public service system to generate thousands of volts , will endanger the public service equipment operation safety of workers .

IEEE1547 and UL1741 safety standards regulations: When AC voltage or frequency exceeds the specification limit, the grid-connected inverter must be disconnected , or when the grid no longer exists, must be completely closed. When you reconnect , the inverter can not immediately transmit power , you need to wait until the inverter detects a nominal system voltage and frequency of the public service more than five minutes . Of course , not only that the inverter duty .

The inverter output power is also used to compensate for effects of environmental factors. For example , the PV panel output voltage and current for the battery temperature and the light intensity per unit area ( also known as " light " ) is highly sensitive to changes . The output voltage of the battery and the battery temperature is inversely related to the cell current is proportional to the light intensity . These and other changes in key parameters result in optimal inverter voltage / current operating point moves significantly .

Drive by using the so-called closed-loop control to maintain a maximum power point (MPP) to solve the above problem, because at this point the product of the voltage and the current maximum . In addition , the dc to ac inverter also supports manual and automatic service operations in the input / output disconnect , electromagnetic interference / radio frequency interference (EMI / RFI) conduction and radiation suppression , ground fault interrupt , PC compatible communication interface and more . Inverter is housed in a rugged box that can run in the outdoor full power for 25 years or more. It was no small feat !

PV inverter market development is the key to the next few years

Typically, the DC can be converted into AC power is called inverter , the complete functionality of the inverter circuit is called an inverter circuit , the process of the realization inverter inverter device or a device called an inverter .

According IMSResearch release " global PV inverter market " Quarterly report predicts 2013 global PV installed capacity will achieve double-digit growth , reaching 35GW. However, the PV inverter market revenues will not grow , manufacturers will usher in a challenging year . As manufacturers try to break into new markets, in a highly competitive market environment, the average selling price is expected to decline by an inverter .

In recent years , China's sustained and rapid development of photovoltaic industry . Has been taking are " two out" model of development, nearly 80 percent of the raw materials imported from abroad, turn over 90 % of the photovoltaic cell assembly products are exported. Such a development model makes China's photovoltaic industry has greatly constrained by foreign markets , so that Europe can not cope with the current launch of the " double reverse" survey , industrial development suffered.

The face of Europe "double reverse" the foreign market shrinking , the Chinese PV companies began to put more attention to the domestic market , while the more recent introduction of the policy of state support is more predictive of the domestic PV market prospects. Meanwhile, as the domestic market is about to open , as the core components of photovoltaic systems inverter http://www.gridtiepowerinverteronline.com/  market demand will also be growing.

2010 , China's photovoltaic capacity of 500 megawatts , the inverter market is about 500 million yuan . Currently, the "Twelve Five" goal of the domestic photovoltaic capacity sharply upwards to 10GW, compared with the previously announced target doubled. Assuming all of these installed and networks, according to one yuan / watt cost calculation , it is expected that by 2015, domestic inverter market will reach 10 billion yuan .

Meanwhile, with the development of the market , the inverter manufacturers are able to successfully enter these growing PV market and profit in the future , but this is not easy. With the development of the South African and South American markets , the PV inverter market will become more fragmented, and the reasonable expectations of long-term strategic decisions in the coming years is essential. "

For those who can undergone many challenges in 2013 , successfully entered the emerging markets inverter manufacturers, along with the PV market towards a more mature in the next few years is expected to return to double-digit growth rate . Meanwhile , the inverter market will no longer be a European center, but spread to more mainland .

How to select the inverter for thin film components

Guangdong bao wei new energy co., LTD not only provide customers with professional design, turnkey photovoltaic power station construction service for the total package side, with the professional knowledge and rich experience, bao wei for a component with inverter selection can give constructive Suggestions.

Due to the high fill factor crystalline silicon components, inverter is easy to find peaks, but the amorphous silicon thin-film batteries components fill factor is lower, the IV curve is flat, modified sine wave inverter need to reset the MPPT tracking step voltage peak point can be found.

Amorphous silicon thin film cells need negative ground at the same time, in order to discharge static electricity, prevent of common-mode voltage than the system voltage and inhibition of photovoltaic phalanx panels of distributed capacitance on the inverter control circuit of the common mode interference. So you have to use internal or external transformer isolation (including the step-up transformer) inverter grid, the grounding line and dc leakage protector in order to protect the personal safety.

Based on negative ground can use the above reasons, the following measures: component anode grounding, grounding is not but in case of static electricity is given priority to, so you can use indirect grounding method, indirect grounding high resistance values, to avoid the direct grounding caused with transformer isolation type inverter incompatible problem.

By practical current of the grounding resistance is very small, not so no transformer isolation type dc to ac power inverter dc leakage alarm, at the same time, the dc leakage protector on the grounding line set up small values can have personnel safety protection. Indirect grounding is the only deficiency in curbing panels distributed capacitance common-mode interference of inverter is reduced, and the problem can be diminished by distributed capacitance (e.g., using no border components) and improve the anti-interference ability inside the inverter circuit to solve, and at present most of the inverter can be suitable.

Japanese PV inverter market or to shortages

Thanks to the high tariff subsidies, many solar companies are very optimistic about the development prospects of the Japanese market. However, insiders pointed out that the vast majority of the Japanese Electrical Safety Environment Institute (JET) inverters are certified Japanese company, which means the inverter supply will be curtailed, perhaps appear inverter shortages.

As the Japanese government launched tempting 42 yen / kWh feed-in tariffs, the global solar companies have turned to the Japanese market. However, Japanese consumers tend to use local brands. Therefore, many international companies that rooftop solar PV systems market competition is greater than the large-scale solar power projects.

In addition, according to industry sources, ground and rooftop PV system grid connected inverter are required to obtain certification JET, and the present, the vast majority get JET certification standards are the Japanese mainland enterprises.

In recent years, due to higher production costs, Japanese solar companies have been uncompetitive. These companies do not have to expand production capacity, with the installed capacity of rapid growth in demand, the Japanese solar market is likely to occur inverter http://www.gridtiepowerinverteronline.com/ shortages.

Secret plug-in grid-connected photovoltaic inverters

Plug- grid PV inverter has emerged in Australia - what they are, how they work, you should also use one ?

PV inverter is an electronic box will be solar panel array generates DC power (DC) into alternating current (AC), applicable to home appliances, and transported to the main grid .

Traditional solar inverters , solar modules can handle multiple output , usually installed in the meter box nearby. Micro-inverter , is a recently developed a new type of inverter, has a smaller size, can work with a single solar panel and installation of solar panels on the back on the characteristics , creating a commonly referred to as the AC solar panels.

In the family system, install the most common photovoltaic inverter requires a qualified electrician to operate, because they are qualified to the wire connected to the meter .

The new " plug and play" inverters are very different - it is a portable device that can be solar panels or small wind turbines connected to the inverter, then directly into the family standard power inverter socket ; electricity for home appliances . Although less than a standard residential solar inverter capacity size, but can be used multiple units.

It sounds like a great idea , but consumers considering the purchase of plug and play gridinverter may need to be careful .

In a forum on energy issues discussed at the problem, which is one point to mention , although Clean Energy Commission (CEC) will plug the inverter marketed renewable energy certificates and obtain approval (RECs), but in a important safety standards , their certification still seems doubtful.

AS-4777 standard , is handling the inverter connected to the grid energy systems and networks in the world. In order to pass Clean Energy Commission (CEC) approved listing of inverter " must AS 4777.2 and 3-2005 ( or equivalent ) and AS3100 ( or equivalent ) standard , in a suitable test lab to get tested ."

However, in AS4777.1 ( installation requirements, Section 5.3.1 ) , it is clearly pointed out: "Inverter fixed wiring should be connected to the distribution switch a dedicated circuit ." If strict compliance with the AS-4777, which seems to avoid the use of any type of plug and play devices.

Another important issue relates to the power distributor. Before the generator can be connected to the grid ( which includes your house to install solar panels and electricity to the grid ) , to obtain the approval of dealers is a must . This approval is not just a brief telephone or verbal , "Yes, you can do " can decide - but need to have paperwork identified .

In addition, the safety of these individuals has also been improved . Plug and Play withanti- islanding inverter functions and features to prevent individuals continue to provide power during a power outage ( because electricity will continue to supply two seconds ) . If the plug from the power outlet , it can still be released instantly to mention electricity.

Finally, consumers consider installing a plug and play grid inverter , and insurance companies should be confirmed to ensure the proper use of this device does not affect the home insurance coverage , especially as a DIY project .

"Tongue" fourth inverter system operators in those years together "chase" over inverter

Inverter system operators and sellers because of the direct trading relationship "bonds ." 2009 years ago, also in a blowout of power plant engineering , for a time because of short supply and inverter systems manufacturers competing to become the "pursuit " of the object . But now the relationship between supply and demand has tended to break the balance, with the second half after wave inverter enterprises stationed in the industry offensive, I am afraid that soon the system 's " smiles " to affect the off grid inverter device businessman nerves . So, in the eyes of system operators , those years together they "chase " over the years has been the inverter is now "modification" into what look like ?

   Determine the wishes of the owners of the inverter system provider choice, price and quality are the most important purchase in selected conditions . Naturally, cost-effective products will win the jackpot , but the high-quality products on the market is clearly not universal . Asked inverter optional aspect prefer stability or efficiency is high, most businesses the answer is to choose the former, but there are system operators gives a more realistic answer - the pursuit of efficiency of small private enterprises or more popular in high efficiency products.

When the inverter technology research update rate lower prices difficult to keep up the pace of product , the cost will be the cost borne by the low-quality , low-price competition has prompted fierce cut quality products into a vicious cycle . Although the power plant system actually receptive inverter " lower profile" in order to save costs, but the solar power inverter link disorderly competition in the market sooner or later affect the downstream industry chain . Interdependent , a lack of quality links will diffuse into the entire industry flawed, visionary system operators prefer to see a stable and orderly inverter market , but also for the quality of its own power station to bring protection.

   Course of development of the industry with similar cells , inverters experienced a shortage of "scarce " stage , and now into fierce competition shuffle. Senior system operators with a vivid metaphor to describe: "In the past twenty dollars a person to do something , now is a dollar twenty people to do something ." System operators face suddenly a dazzling array of inverter manufacturers, upstream from the start of competition brought about by cheap and applauded , but also to the present sensible to shop around. Domestic inverter market varies greatly and homogenization of serious melee, watching and eager foreign counterparts , are for the system to provide a broad range of options , while they have become more cautious. However, the current situation will inevitably crowded bring some disorderly scenes , sustained cheap low quality assurance will , which allows system vendors are beginning to worry .

   Purchase of the inverter , the power plant business in the Chinese market systems tend to domestic line inverter manufacturers. From the quality , the domestic brands are constantly approaching foreign products , cost advantage is indisputable , and choose China inverter timeliness in the aftermarket also bring convenience . However, in the service, the system operators who will be difficult to achieve without ranged pregnant .

   As a leading systems supplier TBEA station , itself in the inverter industry has been achieved , so deep insights into this market . Asked about the views of the inverter manufacturers when Joe TBEA Mr. Chik told reporters , inverters services should be improved, domestic brands have done well , but the new intervention Inverter Suppliers need to improve the quality and stability of the foundation will do high efficiency is our Group's common pursuit of the inverter manufacturer 's directions , but also our priority system integrators bidding objects. PV Group, Mr. Ma Jinpeng Shaanxi also pointed out that the sale of the timeliness of the inverter business is also to be improved.

Whether international giants SMA, or domestic inverter manufacturers in product technology and quality standards and other hardware gradually , the more effort should be devoted to the same effect on the competitiveness of products soft power up . Power inverter as the core component of its operation to ensure stability and play an important role in generating capacity , while the 25-year life of the requirements and needs of the inverter service has been effectively guaranteed. Therefore, the market competition is not the inverter into the power station at its end will be declared , subsequent journey safe and perhaps more will get the system 's love . Therefore, system vendors are also more willing to see more able to provide cost-effective and improve services business to appear as close to the two chains to bring a win-win .

   In those years, inverter " Sentimental face ", but a valuable commodity , " suitors " flock. Today's "she" vibrant, but because at the stage of self-improvement is difficult to stabilize , " character ", so that system operators are no longer fanaticism. Anyway , the inverter power plant manufacturers and system providers are the baptism of wind and rain in the industry become more mature , we look forward to the inverter industry's healthy development of the entire PV industry chain to bring more rich spring.

How to choose inverter thin-film modules

New Energy Co., Ltd., Guangdong Bao Wei not only provide customers with professional stent design for the total package provides turnkey photovoltaic power plant construction services, with professional knowledge and rich experience, Paul Wei inverter for supporting the selection of components and also can give constructive comments.

Since crystalline silicon cell module fill factor is high, the peak point of the inverter is easy to find, but amorphous silicon thin film battery pack is relatively low fill factor, IV curve is gentle, the inverter need to set the step voltage tracking MPPT to find the peak point.

Meanwhile amorphous silicon thin film batteries need negative ground, in order to discharge static electricity and prevent common mode voltage to ground exceeds the system voltage and the inhibition photovoltaic array panels on the distributed capacitance of the inverter control circuit common mode interference. So you must use an internal or external transformer isolation (including step-up transformer) for grid tie power inverter  grounding lines need to add DC leakage protection device to protect the personal safety.

Negative ground is not grounding lightning protection components, but mainly to prevent static electricity, so you can use indirect grounding method, using a large value resistors indirectly grounded to avoid a direct cause and without grounding transformer-isolated on grid inverter incompatibility problems . Since the grounding resistor through the actual current is very small, will not cause the inverter without transformer-isolated DC leakage alarm

Meanwhile earth circuit DC leakage protection settings can play a small role in protecting the safety of personnel. The only downside is indirectly grounded in the inhibition of cell panel distributed capacitance of the inverter reduces common mode interference aspect, and this problem can be reduced distributed capacitance (eg with no border component) and the inverter internal circuitry to improve noise immunity resolved, and now most of the inverter can be fit.

Sun power inverter 4105 and the first to receive German dual certification BDEW

Recently, sun power SG15KTL inverter passed German certification authority of the assessment test , won the country 's first medium-voltage grid in Germany Directive (BDEW) certificate. Prior to that, which has made Germany the inverter voltage grid Directive (VDE-AR-N 4105) certificate , sun power has thus become the first domestic simultaneously through the German medium and low voltage grids instruction double certification.

Germany is a global leader in renewable energy state , its renewable energy generation and grid requirements represent the highest level with the global trends. 2008 , BDEW ( German Federal Association of Energy and Water Resources ) issued " with the medium-voltage grid connected power system technical specifications" , the dc to ac inverter and network performance , particularly in the static and dynamic grid support made ​​178 times harmonics , receiving instruction grid active and reactive power control ,

Grid voltage is 0:00 remains to grid and provide reactive support low voltage ride through (LVRT) requirements and many other technical requirements . With BDEW medium-voltage grid corresponding to the commands , in August 2011 , they released low-voltage grid in Germany Directive - "and the low-voltage grid connected power generation system technical specifications " (VDE-AR-N 4105), on a strict low-voltage grid access standard restrictions, requirements to the grid photovoltaic power plants , the use of inverter must provide this certification.

Series of good news shows that countries have solar power on a very important position

May 23 held a State Council executive meeting made ​​it clear that " self- supporting solar and other new energy products into public facilities and family ." From which we can clearly appreciate the country will accelerate the development of solar distributed generation .

In fact , the favorable development of distributed power generation is not limited to this. Back in April , " distributed generation management approach " and " and network management approach" Bill had been introduced to the public for comments. And subsequently , "renewable energy quota system ," the discussion paper issued in early May and is expected to begin early next year I implemented .

Series of good news shows that countries have solar grid tie inverter power on a very important position , and began to increase efforts to promote the development of solar distributed generation . Distributed generation is relative to the centralized power plants in terms of . According to " distributed generation and network management approach ( draft ) " , " distributed generation " is defined as : Located near the location of the user , not to the large-scale long-distance transmission of electricity for the purpose of the power generated by the user in addition to their own use and the nearest use , the excess electricity fed into the local distribution grid power generation facilities , power generation systems or power output of the energy cascade utilization of integrated multi- CISS .

Market Distribution of electricity and solar energy distribution does not completely coincide . As the larger eastern electricity , land prices are more expensive , if the construction of large-scale centralized ground station will greatly improve the cost , is not conducive to large-scale promotion of solar power ;

Rich in solar energy development in the western region centralized power stations, long-distance transport of electricity will emerge loss problems . Therefore, the state of solar distributed generation policy guidance and support , and promote the domestic PV gridtiepowerinverteronline market installed capacity from large centralized to distributed power station roof and small changes in public facilities , in fact, fully in line with the status quo of China's PV market development law .

According to experts , the domestic development of distributed power plants need to focus on solving three problems , namely policy areas , pattern links, technical aspects . At present, the European and American market has formed a very mature about the distributed generation model, through the planning guide , incentives, reasonable price mechanism and other means , many developed countries, the proportion has been fairly distributed energy high . For example, the amount of distributed generation in Denmark even more than half of total electricity generation .

With the domestic policy-oriented determination of foreign advanced model will be the promotion of rapid replication , so now the most important and need to be addressed , but is that technical aspects of the problem . At present, because solar power itself is unstable, the domestic terms of the relative aging power grid will have a relatively large impact , even a threat to network security issues. To solve these problems , in addition to hardware upgrades from the grid , the solar power system side , especially the technical reliability of PV inverters is particularly important .
