In addition to the cooling fan and circuit breaker switch components, there are a large number of solid state electronic devices in the UPS. They basically do not have mechanical wear, so they can work in the best running condition for a long time. It is necessary to find out the signs of trouble and prevent the hidden trouble from expanding, we must make the UPS work in a suitable environment and do routine maintenance. The working environment of UPS should be the same as that of the computer. The temperature should be controlled above 5 degrees Celsius and below 22 centigrade. The relative humidity should be controlled below 50%, and fluctuation range not exceeding 10%. Of course, it is equally important to these factors that keep the UPS workshop clean, dust-free, unpolluted, and harmful, as these factors also affect the service life of the UPS and cause trouble.

In the UPS daily maintenance work, engineers need daily routine inspection, its main purpose is to run the accumulated experience of online uninterruptible power supply and timely detection of fault signs, so the daily routine inspection should be careful.

Hybrid solar inverter mainly has the function of solar on and off grid power generation, that is to say, in the case of normal power supply, the device closes the bypass relay to realize the power supply load on the household electrical appliance; When the power supply of the power network is not normal (such as the power grid is off, the power grid voltage or frequency fluctuation is relatively large), the device can carry out the power supply for the household electrical appliance after inverting through the battery. Under the condition of suitable sunshine intensity, the device can also be connected to the grid and sold to the grid to gain benefit when the solar power generation function is normal.

In terms of technical implementation, the device consists of the following units:
First is the inverter unit, the unit receive from solar power from solar panels and DC bus box, through the maximum power point tracking circuit, stable DC bus voltage, finally into the public power grid power generation by the inverter unit.
Second is the off grid solar inverter unit, when power supply is normal, through the bypass relay to the load power supply, at the same time to charge the batteries; when the power grid is out of order, through the inverter load to achieve uninterrupted power supply. At this time, if the PV module generates electricity, can be supplied to the load through the solar power inverter, and the battery is charged simultaneously.
Third is a switching unit, when the unit is in suitable light condition and the power grid is abnormal, supply power to the load through switching relays and other devices.
Fourth is the other auxiliary units, such as isolation unit, storage battery management unit, etc., used to achieve the management of storage battery, into the network, meters, network meters, solar panels and so on.

In general, the solar hybrid inverter can effectively overcome the existing problem of solar inverter is only suitable for grid connected generation, and when off grid inverter in the weak sun light, the electricity load is limit, can effectively improve the utilization efficiency of solar energy, especially suitable for power grid power supply is not stable or high cost.

Today, all aspects of information technology in the field of industrial production, operation and management has been applied widely and deeply, at the same time, a variety of high-end precision equipment is also increasing, the industrial production to fine development, which put forward higher requirements on the quality of UPS. Not only the continuity of the power supply should be guaranteed, but also has special requirements for the purity of the power supply.

However, it is necessary to point out that applied in power industry, on the one hand to the reliability of power supply, on the other hand in the operation of power equipment is often affected by various factors, resulting in power quality can not be effectively protected, for example, the grid pollution, natural lightning, large capacity motor starting, the switch of power factor compensation capacitor and so on, will directly affect the power quality and cause voltage fluctuation, pulse power interruption etc.. In this context, UPS has been widely used in industry for its advantages of high voltage stability and uninterrupted supply of pure electrical energy to the load. It provides a reliable power guarantee for industrial production and management.

Based on the particularity of industrial applications, compared with the UPS used in general data room, the industrial grade UPS has great difference in operating environment, actual load and so on. First of all, in the industrial manufacturing process, environmental conditions often accompanied by dust, fog, high temperature, noise, dry or wet and other poor conditions, while the industrial grid environment is very unstable, often face wave disturbance surge, peak limit and other power grid pollution. Secondly, the load of industrial UPS is very complex, and it is mostly inductive load, capacitive load, fluctuation and high peak impact load and so on, large impact on the current. Therefore, integrating all aspects of objective factors, in the actual application, with UPS in the foundation to ensure the high reliability and high availability of the industry, the need to have excellent performance in various aspects of environmental adaptability, protection grade, load capacity, can effectively deal with the test of industrial applications in harsh operating environment, the power supply environment load and environment.

At present, in the field of China UPS industry, the major mainstream manufacturers features specifically for industrial applications and the actual needs, increasing research and development efforts, launch high-quality industrial UPS power supply products, to provide power protection for the important equipment of industrial intelligent precision instruments, industrial automation systems etc..

With the solar power system apply more and more widely, the grid connected inverter market has also played its role as a key component of solar energy installation. In order to realize the stable and reliable operation of the grid, the grid connected inverter market must ensure the quality of the transported power and the stability of the whole grid. To keep pace with these requirements, grid operators will publish new grid operating rules that each manufacturer must follow to oversee increasing usage. Another problem for solar inverter manufacturers is that the relevant policies and regulations of different countries are different. In most cases, different projects, even in the same place, should follow different rules and regulations.
An urgent problem for grid connected solar power inverter manufacturers is that they must comply with the technical requirements of grid connected solar devices which are different in different countries. All of these countries and regions have different requirements for inverter voltage and frequency from the grid. In addition to the necessary adjustments to different system parameters such as fault crossing, the status quo also leads to higher production costs.

Technically, so far, common inverter designs use the following parameters as standard: the temperature range is between -25 ~ 50℃; the estimated period of use will be about 20 years; conversion rate is usually over 94%; with electromagnetic compatibility; lower cost; higher reliability; all power grid faults can be carried; the power factor approaches 1 while maximum power point tracking (MPPT) can be performed simultaneously.

At present, the function of most inverters is to convert the DC voltage produced by the solar device into sinusoidal AC current waveform at the switching converter to ensure the connection and synchronization between the generator and the power grid. However, this function subsequently changed. The new standards put forward different requirements for solar panel power inverter in various degrees: the development of key characteristics such as efficiency, cost and stability; compatibility with SiC, Gan and other new materials; integration with micro inverter and other innovative technologies; effective maximum power point tracking control function; and follow various new specifications, such as “anti island effect” testing.

In terms of requirements for new materials such as silicon based MOSFET, SiC technology has undergone significant changes in the field of carbide, making the production capacity of MOSFET far beyond the IGBT, especially in high pressure and high temperature conditions. This provides a feasible way to improve the efficiency of solar powered inverter.
