At present, high frequency tower type UPS and modular UPS can achieve 96% highest efficiency value, but this can only be achieved over 50% load rate. As mentioned above, because of system redundancy and advance planning, the UPS load rate is about 20~40% under common conditions. High frequency tower UPS under this condition can only achieve the efficiency of 94~95%, while the mainstream modular UPS generally have a “dormant module” characteristics based on a certain system redundancy, can sleep a certain number of modules (can be manually or automatically), keep the work rate of  modular UPS system  in the relatively high area, which remain in 96% of the highest point of efficiency. And some  modular UPS manufacturers  considering the module aging time may be different, develop the “rotation dormancy function”, namely every set period, rotate the dormancy module, average aging time of each module, to improve the overall UPS system life.

To reduce the cost and increase the benefit is the key factor for  solar inverter manufacturer  to occupy the market, in consideration of market competition, subsidies decline, overcapacity, and the goal of parity transformation of conventional energy, all above is pushing solar energy industry to reduce the cost and increase the benefit. How much room for price cuts? In order to achieve the goal of solar parity on power grid, there must be room for price cuts, especially the solar components accounted for nearly half of the system investment, but also to accelerate to reduce the cost and increase the benefit. While the solar inverter as the key component of the solar power generation equipment and power grid, but the fastest price reduction . In the solar power plant fault, the fault caused by the quality of equipment accounted for 50%, of which the solar inverter is the highest, which is the facts need  solar inverter companies  pay attention to. If simply r...

The concept of  modular uninterruptible power supply , originated from the requirements of the customer to simplify the maintenance of the system, hoping to not affect the critical business in the case of failure, can restore the system with simple replacement operation.  Modular UPS manufacturers  naturally design the UPS parallel system into a modular structure, which is the source of decentralized bypass program. The advantage of the distributed bypass scheme is that the control is simple and easy to develop, only need to transplant the original UPS parallel system is and optimize the monitoring section; the cost of cabinet is low; bypass devices because of small capacity, the cost is relatively low; static bypass has multiple redundancy. The centralized bypass scheme is a technical route developed after the distributed bypass, and compared with the traditional UPS parallel system, has made a very big change from the current sharing control, system coordinati...

Modular type UPS  is a high power UPS system which divided into several sub modules in parallel, controlled by the optimized system, realize the system online expansion and maintenance, and greatly improve the system reliability, availability and energy saving effect, reduce the maintenance cost, in recent years has gradually become the mainstream choice for customers. 1.Decentralized bypass structure Decentralized bypass structure, that is, each power module contains rectifier,  inverter  and battery conversion and other parts, but also with the same capacity of the power module static bypass, can be considered as a UPS with no liquid crystal monitor. A plurality of modules are connected in parallel in the cabinet to form a system, and the relation between the modules is similar to the traditional multi parallel UPS system. When the system is switched to the bypass power supply, the load is connected in parallel by all the power modules. 2.Centralized bypass s...

1.System voltage System voltage is also called the rated operating voltage, refers to the  solar power system  DC operating voltage, voltage is generally 12V and 24V, medium and large power controller can be 48V, 110V, 220V 2.Maximum charge current The maximum charge current is the maximum current output of solar cell components or square, according to the size of the power is divided into 5a 6a 8a 10a 12a 15a 20a 30a 40a 50a 70a 100a 150a 200a 250a 300a and other specifications. Some factory instead of the maximum power of the solar cell components to express this, indirectly reflects the maximum charging current. 3.Solar array input channels Small power  solar controller  is usually a single input, while high power  solar mppt charge controller  is composed of solar cell array multiple input, general high power solar controller can enter the 6 channels, the most accessible 12 channels, 18 channels. 4.Circuit loss Circuit loss is also ...

1.Industrial workshop: especially in the large electricity consumption and expensive electricity fees factories, usually the roof area is large, wide flat roof, suitable for installation of photovoltaic arrays and due to the large load, distributed  solar power system  can do to offset part of local consumption, online consumption, thereby saving electricity. 2.Commercial buildings: it is similar to the effect of industrial workshop, the difference is that the commercial buildings is mostly cement roof, more favorable to install photovoltaic array, but often have the aesthetic requirements of the building, in accordance with the characteristics of commercial buildings, office buildings, hotels, conference centers, resorts and other buildings, the characteristics of the loads generally showed higher in daytime, while the night is low, can better match the photovoltaic characteristics. 3.Agricultural facilities: there are a large number of usable roof in rural areas, includ...

Low frequency UPS  technology appeared in the 70s of last century, its rectification frequency and work frequency is the same. Limited to the development of semiconductor technology, the breakdown voltage of IGBT in inverter can only achieve 600V, so the bus voltage is limited, the output voltage of the inverter can not achieve 380V; and the low frequency inverter is the full bridge circuit, the output for the three-phase line, unable to meet the demand of single-phase IT load and four wire and three-phase load, must be Δ-Y conversion. In order to solve these problems, the manufacturers add the transformer in the  low frequency inverter  output side to elevated the voltage and generate the central line, so that the to meet the requirements of the output voltage of the load, which is the real purpose of the low-frequency built-in transformer. By the 90s of the last century, the third generation trench IGBT was invented, its ability to enhance the withstanding voltageto ...
