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.

The solar MPPT controller of the solar power system only needs the protection of induced lightning (electrostatic induction, electromagnetic induction) and lightning wave. The protection of the controller is to install an over voltage protector in the junction box of the solar array array and the input end of the controller. The input end of the inverter and battery in parallel, and the output end of AC power distribution cabinet is connected with the input end of the inverter, so the protection is in the output of the inverter (i.e., between the fire line and the zero line and the ground, and between the front line and zero line) install overvoltage protector. At the same time, the equipment in the computer room is reliably grounded, and the same grounding potential as the grounding body of the array and the outer frame is arranged to prevent the invasion of the lightning wave and the induction thunder. The protection of AC power distribution cabinet is at the output end of AC power distribution cabinet, that is, the overvoltage protector is installed between the live wire of the overhead line and the ground, between the zero line and the ground, and between the fire line and the zero line. This lightning protection devices all installed in the rain and dust, fixed on the overhead wire rod, fixed position from the overhead ground as close as possible.

The protected device in controller is mainly IGBT, which is generally greater than 500V between the positive pole and the DC voltage, the pulse pressure is 1300V, the normal working voltage between positive and negative pole is DC 260V (up to 390V in a very long time), to achieve the purpose of lightning protection, it is impossible to perform 1 level protection in the 12v mppt solar charge controller, we must use two levels of protection plan:

1 level lightning protection is carried out in the transmission line box behind the battery board, and an overvoltage protector is respectively arranged between the positive pole to the ground and the negative electrode to the ground; An overvoltage protector is arranged between the positive pole to the ground and the negative electrode to the ground at the input end of the MPPT solar charge controllers; The distance between the line box and controller behind the battery board shall be greater than 10m.

Outdoor telecom stations are mainly built in towns, rural areas, mountainous areas, suburban areas and urban outdoor environment, so as to eliminate the signal blind spots in these areas, alleviate the pressure of network capacity or improve the quality of service. The power grid environment in these areas is more complex, and even power blackouts, sudden blackouts and other situations are common. In order to ensure the reliable and stable operation of the telecom network, operators need to use special outdoor communication power supply or outdoor UPS. Due to the special environment of outdoor UPS, the quality and performance of outdoor UPS are different from those of indoor power supply. At present, operators in the choice of outdoor power supply products, should evaluate mainly from the following three aspects.

The reliability of power supply
Telecom power supply products is mainly to provide stable power, pure and uninterrupted to the telecom network, protect the equipment from power pollution, protect key business system can run in case of a sudden power failure, which requires equipment with high availability and reliability. Especially for UPS outdoor, the power grid environment they faced is more complex. It is faced with many problems, such as power outages, voltage spikes, voltage surges, frequency drift, harmonic interference, voltage fluctuations and so on. Therefore, the quality of the components is required to be higher, in order to ensure the service life of the product, and the adaptability to the grid is stronger, and can play a better role in stabilizing the voltage, filtering and purifying the current. In addition, the UPS itself should have a certain self-protection and fault diagnosis capabilities, such as lightning protection, short-circuit protection, etc., in order to better provide power support for the telecom network.

Protective performance
This is the basic difference between the outdoor UPS and common indoor power supply equipment, due to the it is placed under the sunshine, wind and rain outside, easily affected by environmental temperature and humidity, dust, salt fog and other conditions. As outdoor rated UPS, the shell protection level required by the industry shall be IP55 and the shell of the outdoor battery cabinet shall be up to IP44.

Energy saving and environmental protection
Energy saving and emission reduction is not only a national industrial policy, but also an enterprise development strategy. To build a green telecom network, the basic requirement is to use energy-efficient, environmentally friendly and safe infrastructure products. Operators in the choice of outdoor power supply equipment, can consider from save energy, land, environmental protection and other aspects: Energy saving can reduce energy consumption and have a direct effect on reducing operating costs; Saving land can reduce the investment of the construction of the site and reduce the cost of the enterprise land; And environmental protection is particularly important, outdoor UPS and environment is in close contact, directly affect our living environment, it must meet the national and industry standards in the electromagnetic radiation, audio noise, pollution and other aspects of materials.

Solar inverter in accordance with the installation environment can be divided into indoor inverter and outdoor inverter. Shell protection grade of indoor home solar inverter is low (usually IP20), forced air cooling is often adopted, higher requirements for installation site (requires a good ventilation system), the existing buildings need to be reformed to meet the requirements of installation environment, high cost; The outdoor solar inverter with natural cooling mode has high protection level (usually IP65), and the required environmental modification is few and the cost is low; At the same time, because the inverter is installed outdoors, the noise caused by the operation will be greatly reduced the impact on the users, but it needs good equipment protection.

On the other hand, the choice of the size of the inverter can be optimized according to the installation conditions. If the installation site is not clear in the initial design, the small power solar inverter should be chosen as possible, to realise the multi-channel independent power tracking, choose micro inverter to achieve the MPPT of single solar panels when necessary, so as to avoid the later problems caused by the space is not large enough, or the imbalance of power series not enough rules etc..
