Improving the conversion efficiency of the solar inverter is the biggest problem in the solar photovoltaic power generation. Since the output volt ampere characteristic curve of photovoltaic array is nonlinear, and has a close relationship with the solar radiation intensity, environmental temperature, rain, fog and other weather conditions, with the different sunlight intensity and ambient temperature, its voltage is changed, the output power also produced very big change, so the solar cell is a unstable power supply. In order to output as much power as possible under the same conditions of sunlight and temperature, improving the efficiency of the system, the MPPT of a solar cell array is proposed. The use of MPPT in the system can improve the conversion efficiency of the solar inverter system, but also to play the greatest potential in the light output power of photovoltaic array for any sunlight intensity, make full use of solar power inverter output.

Solar panels inverter systems  control scheme is: photovoltaic battery converse solar energy into electrical energy, and the series parallel tuned to DC voltage which meet the SPWM inverter, through inverter and filter inductor formed and grid voltage with the same frequency and phase of sinusoidal current, the realize the grid inverter using SPWM (sine pulse width modulation) inverter technology. According to the periodic condition of power system, the following 3 conditions should be satisfied when the SPWM inverter circuit is connected to the grid: 1.In the renewable energy feedback system, the output voltage of the inverter is close to that of the city power, and the pressure difference should be less than 10%. 2.Inverter output frequency close to the frequency of the city power, the general frequency difference is not more than 0.4Hz. 3.Inverter output current and the city electric voltage phase is same, usually this phase difference should not exceed 10 degrees. PV grid conne...

In general, the backup time of  commercial UPS  battery is not as long as in industrial applications, usually in the 10-30 minutes or so, the charging capacity does not require the capacity increasing design. UPS battery charger is generally designed to be able to back the lead-acid batteries, which back up time is 15-30 minutes, to the capacity of 95% in 8-10 hours.Compared with the commercial UPS, in industrial applications, charging capacity must have higher ability, because the battery backup time from 60 minutes to 8 hours or more, which requires the charger in the UPS system has enough battery recharge capacity. In many cases, the use of backup time for 4-8 hours of battery configuration. In the industrial field of UPS, in order to better adapt to the demand of high and low temperature environment, nickel cadmium batteries have been widely used, in addition to meet the  industrial grade UPS  charger for lead-acid batteries, also need to meet the charge and disc...

The main factor of a  MPPT Solar charge controller  is the comprehensive system of circuit protection function. This is a key role of the controller. The traditional common charge and discharge controller can only be used in general occasions. But the rationality of the design of the protection circuit, the selection of parameters is very important, and the rest is the actual precision of the controller. Some customers are often found that after a period of time, especially after the continuous overcast and rainy days, the street lamps will be not bright for several days or even several days, while detect the voltage of battery is normal, controller and lights are no fault. This problem has let many developers doubt. Remove of other factors, then comes down to the controller, that is under voltage protection voltage parameters: 1.The value is set too high, the undervoltage recovery for longer time, also caused a lot of days are not light. 2.The parameter setting is reasonab...

Many  industrial UPS  environments, especially in some power generation applications, are likely to be in the higher ambient temperature conditions (>30 degrees) and particulate pollutants in the air. So require the industrial UPS can work in a large number of non conductive dust and high ambient temperature. Work in the ambient temperature which at least 40 degrees, and some occasions even up to 50~55 degrees. On the contrary, the commercial UPS application environment is almost controlled within 30 degrees, and very clean. The use life of any UPS system will be decreased in a high temperature environment, the key components of the UPS which is the most vulnerable to high temperature environment is the  industrial grade UPS  components (such as DC capacitor) and the battery. In the high temperature environment may make their life shortened, unless choose high temperature capacitors. In  commercial UPS  applications, UPS users may not require a long...

1.The difference of circuit structure Pure online UPS  adopts double conversion on-line circuit structure, power input through AC/DC conversion, part of the power to charge the battery, most power converted to alternating current supply load. When the city electricity failure, UPS supply power to the load by the DC/AC conversion. When the UPS fails, it will automatically turn to bypass operation. Online interactive UPS  using online interactive circuit structure, the city electrical input through the filter circuit to its surge suppression, filter output to the load, inverter as the charger to charge the battery at this time. When the city electricity failure, Online interactive UPS use the battery power output to the load converted by the DC/AC. 2.The difference of the application On line interactive UPS  provides high quality power protection for servers and network equipment. Pure online UPS in addition to the protection of the server and network equipment, but al...

Compared with traditional UPS,  modular UPS  has a considerable advantage. Its advantages are mainly in the following three aspects: 1.Installation is simple, easy expansion, saving investment. A  modular type UPS  power supply system can make the capacity on demand, with the development of business, and achieve “dynamic growth”. Both to meet the needs of the expansion of the late business, but also to reduce the cost of the user’s initial acquisition. 2.Parallel redundant, stable operation, high reliability. In the rackmount modular UPS, power module is parallel redundancy, each module is equipped with input and output insurance, and input and output relays, any module failure does not affect the work of the whole system. In the traditional UPS products, the security of the user is generally used in the “1+1” or “N+1” parallel redundancy, only one fault tolerant. In the modular UPS system, users only need to buy the corresponding power module to achieve the “N+...
