The Road to Change, the Application of Solar Energy in the Communications Industry

图片
When I think of the off grid solar applications, one main sector that has tremendous captive power requirement is telecommunications. With consistent fall in the average revenue per user and a whopping 86% increase in the minutes of usage in the past decade, India is one of the countries with increasing market competitionand highest number of MoU’s. The numbers of operators have almost tripled in the last 3 years and there is a mad headed competition to reduce the cost especially if theservices have to be made affordable to the sub urban and rural areas. Rural teledensity improvement is possible only with low cost service. With power contributing to 25% of total network cost, one of the key areas where the telecom providers are looking forward to reduce cost is energy. Unfortunately, poor quality of grid supply in suburban and semi-rural areas and no grid supply at many rural areas is increasing the energy cost for the telecom providers. 10% of telecom towers in India have no powe...

Environmental adaptability of solar on grid inverter

Environmental adaptability refers to the ability of a product to achieve all its intended functions, performance and non-destructive ability under the action of various environments it may encounter in its life cycle prediction. It is an important quality characteristic. It can be seen that environmental adaptability has two elements, one is product and the other is environment. The same product has different environmental adaptability in different environments, and different products have different environmental adaptability in the same environment. Environmental adaptability is one of the quality characteristics of equipment. Once the product is finalized, the materials, components, structural composition and selected process have been solidified, and the environmental adaptability for the given environmental profile is fixed. It can be seen that environmental adaptability is the inherent quality characteristics of products, determined by design and manufacturing, and guaranteed by ...

How to develop 48V power supply structure

图片
After hundreds of years of development, the  48V power supply  structure in the telecommunication industry has become very standard and universal. The industrial chain and ecology are very mature, so that most of the network equipment can directly support the 48V DC power supply. Even before the data center industry tried to use the 48V power supply architecture, but the traditional way is to learn from  UPS  to put 48V power and batteries in the power room and battery room of the data center. The problem caused by this method is that the traditional server equipment often lacks the power to support 48V input directly, and the 48V power supply brings about the power line investment, transmission line voltage drop and transmission line loss when the low voltage and long distance transmission. Finally, the traditional 48V power supply technology can not be carried out in the data center industry. But with the development of the whole cabinet technology, and the pursui...

The difference between the voltage regulator and the UPS

图片
The functions are different, the voltage regulator and the UPS  uninterruptible power supply  are widely used, but there is a difference between the regulator and the UPS power supply, and many people are always wrong to think that the regulator is the UPS. So, what is the difference between UPS and voltage regulator? UPS power supply  is divided into an online UPS power supply and a backup UPS power supply. The common computer is equipped with a backup UPS power supply. The backup type including the voltage stabilizing part, which adopts the relay shift voltage regulation mode, and the voltage stabilizing effect is very poor, so it can not calculate the voltage stabilizer. When the online UPS power supply is working, firstly convert the city into DC to charge the UPS battery, and the  inverter turns the DC power into alternating current to power the load. As the city electricity passes through the exchange process to the DC, and then to the AC, the original...
