Tower UPS need to buy a new expansion one, the new UPS should be installed in place, bypass the other UPS in the system and then connect the new UPS to the system, the whole procedure is not only high investment, long installation time, because the entire system is in the bypass state while incorporate the new tower UPS, existing power interruption risk which leading to load power down. While the modular UPS as long as the layout of the distribution system is optimized in the early stage, the load can be increased by adding modules, and the uninterrupted power supply to the original load can be guaranteed during the expansion process.

If lightning occurs near the solar cell components, will produce electrostatic induction voltage on the solar panels. Since the positive and negative leads of the solar panels are very close, a ground induced electrostatic overvoltage UC is formed on the two wire simultaneously.

It can be seen that there is no electrostatic overvoltage in the positive and negative wire loops of the battery board, that is, electrostatic induction lightning strikes cause no damage to the internal circuit of the battery board. When lightning occur near the cloud panels, strong electromagnetic field will appear sharp change of magnetic flux in the battery, the conductor will produce excessive voltage and current. It is obvious that the overvoltage and overcurrent will only occur on the closed loop of the aluminum alloy frame and enter the ground through the support. Therefore, the electromagnetic induction overvoltage will not cause impact damage to the solar cell assembly. In addition, the height of the solar cell square is much lower than that of the low-voltage overhead output pole, so the grounding of the pole can be used as one of the lightning protection measures of the battery square.

Surge protection is achieved by installing surge protectors on live cables, reducing the damage caused by surge and lightning overvoltages to equipment. Lightning surge invasion routes of solar power generation system, in addition to solar cell array, and distribution line, ground wire, so the solar power generation system needs to take the following protective measures:
1.Install surge protection device at each DC input end of the solar inverter.
2.Install surge protector in the grid access control cabinet to prevent the lightning wave intruded along the connecting cable.

As an electronic product, solar power inverter is composed of many multi-element devices. Also known as power regulator, according to the inverter in the solar power generation system can be divided into off grid solar inverter and on grid inverter. For inverters used in grid connected systems, can be divided into transformer type inverters and no transformer inverters according to whether they have transformers or not. When operating the grid connected power generation, because of its particularity, can not be careless in the installation and maintenance, otherwise, otherwise, there could be a security risk.

Maintenance should pay attention to the following points:
1.Before any maintenance work, the electrical connection between the inverter and the power grid shall be switched off first, and then the electrical connection on the DC side should be disconnected.
2.Wait at least 5 minutes until the discharge of the internal components is completed before repairing.
3.Any fault that affects the safety performance of the inverter must be eliminated immediately before the solar panel inverter can be turned on again.
4.Avoid unnecessary circuit board contacts.
5.Observe ESD protection and wear antistatic bracelet.
6.Observe and comply with the warning signs on the product.
7.Visually inspect the equipment for damage or other dangerous conditions before operation.
8.Note the thermal surface of the inverter. For example, the power semiconductor radiator and so on, after power failure of the inverter for a period of time, still maintain high temperature.

After the maintenance of the inverter, make sure that any fault that affects the safety performance of the inverter has been solved before the inverter can be turned on again.

The development of computing has posed a great challenge to the power supply system of the traditional data center. Innovative technologies and applications of cloud computing have brought opportunities for operators to transform into integrated information service providers, and have become one of the key development strategies for the telecom industry. As an important IT infrastructure to ensure the uninterrupted operation of data centers, the traditional power supply system has doubled its pressure.

The rise of cloud computing has greatly improved the computing density of equipment, which has led to the rapid expansion of the power density. The demand for power supply system, cooling system and computer room increases correspondingly, but the feasibility of expansion or large-scale reconstruction of the data center is very small. This is one of the major challenges that cloud computing has brought to the management of data centers.

The age of 4G has begun, further growth of the data traffic require telecom operators to improve more data center, build safe, green, intelligent data center will be the focus of the sustained attention of the operators. With the idea of integration of data center, high frequency UPS is the most fundamental guarantee for the reliable operation of all facilities in data center. The intelligent management and remote monitoring of UPS power supply will become the key point of technological innovation of data center.

The process of building a new generation of green data center, improve data center energy utilization, strengthen the safety management of power system, the demand for intelligent power management and remote monitoring technology has laid the foundation of innovation.

The intelligent monitoring and management of data center UPS can ensure the reliability and availability of power supply system, facilitate centralized management of equipment, reduce management costs and improve efficiency. Especially for the users who have many branches and have built LAN environment, the centralized monitoring of the whole power supply system will greatly improve the level of scientific maintenance of the data center.

At present, most of the core data center installed intensive, various types of power equipment is more scattered, difficult to achieve centralized management, at the same time, many base stations deployed in remote locations, and is difficult to manage, and some server room environment has some effect on human health, these problems are widely used. With the maturity of technology and the increase of demand, the intelligent and remote control of UPS power supply in power room will gradually become the common demand of power management.

Tower type UPS needs to be installed and transported as a whole, so it will be difficult. Such as the capacity of 400kVA tower type UPS weight is about 1500kg, the volume of more than 3 cubic meters, the tower UPS will be affected by lack of transport channel, high weight and the difficult transportation, while modular uninterruptible power supply can be separated from the handling module, frame, on the other hand most of the models can be transported separately, tower UPS may encounter problems will be smoothly done or easily solved.
