Overload capacity: 110 ~ 130% of the load can be overloaded for 10 minutes, 130 ~ 150% of the load can be overloaded for 1 minutes
Charging current: 4.5A (each module)
Support frequency conversion mode 50Hz input, 60Hz output or 60Hz input, 50Hz output

Digital control

High frequency UPS adopts the most advanced DSP as the central controller, its powerful computing capabilities can realize the traditional function in most of the UPS now by software, not
only greatly improve the accuracy and reliability, and easy to upgrade and maintenance.

Intelligent charging

Modular high frequency machine adopts advanced three phase charging method:
The first phase of large current is constant current charging, fast recharge about 90% of the electricity;

Second phase is pulse charging, can fully charge the battery;

Third phase is the constant pressure to maintain, to ensure that the electricity does not lose.

This can be a good balance between fast charging and prolonging the life of the battery, saving the battery cost for the user.

N+X wireless parallel redundancy

Using advanced wireless parallel control technology, compared to the wired parallel to reduce the single point of failure ( can work even if the steady-state operation of the line fault), but also
improve the reliability.

Parallel battery

Modular high frequency UPS adopts the double cell input structure and advanced control strategy, and the 6 kva online UPS system fully share the same set of battery, which greatly saves the cost of the battery.

Advantages of the solar power system
1.Sunshine everywhere, not subject to geographical restrictions.
2.Safe and reliable.
3.No noise, no pollution.
4.Do not consume resources.
5.No need to set up long distance transmission line.
6.The installation is simple and convenient, and the construction period is short.
7.Make financing easier.
8.Easy to implement step by step.

Disadvantages of the solar power system
1.Restricted by time period, geographical position and weather condition.
2.Light conversion efficiency is low.
3.High cost.

1.The extension of modular Uninterruptible Power Supply is better
Tower type UPS need to buy a new expansion machine, the machine should be installed in place of the system in other UPS to bypass the new machine access system, the whole procedure is not only high investment, long time installation, existing power interruption risk load power down, when incorporated into the new machine because the entire system is in the bypass state. The modular UPS as long as the initial planning of the distribution system, you can increase the module to match the load of the upgrade, and in the expansion process to protect the original load of uninterrupted power supply.

2.Modular type UPS is easy to transport and install
Tower type UPS needs to install and transport as a whole, large single UPS will be more difficult. Such as the capacity of 800kVA UPS weight is about 1500kg, the volume of more than 3 cubic metre, the tower type UPS will be lack of transport channel, transportation difficult to transport because of its high weight, modular UPS can be a separat to handling module and frame, on the other hand, most of the models can be transported separately, the problems can be easily solved.

3.The practical operating efficiency of modular UPS is high
At present, high frequency tower type UPS and modular UPS can achieve 96% of the highest efficiency value, but this is in the load rate of 50% or more. And as mentioned before, because the system is redundant and advanced planning, UPS load rate of common conditions in the 20~40% or so. High frequency tower type UPS can only achieve the efficiency of 94~95% under this condition, 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), work rate is relatively high in the area. So UPS system, which remain in the vicinity of efficiency the highest point of 96%.

Oct.15-19, 2016, Sorotec successful attended the 120th Canton Fair in Guangzhou, China. As a professional power solution expert, we presented many of our newest products on the booth, such as: 48VDC Solar Power System for outdoor communications base station, On – grid Solar Inverter with energy storage, Multi-function off -grid Solar Inverter, Solar Power Inverter System with battery and High Frequency Online UPS on the exhibition.

There are a large number of professional visitors came to visit SOROTEC’ booth. They showed a keen interested in SOROTEC ‘s new products and had a deep communication with our technicians and sales person. After the discussion, we know more about customer’s needs. During the show, many customers have a deeper understanding about SOROTEC’S products and show a stronger desire for cooperation. Cheers!

Thanks for all clients visiting our booth and sharing the products with us and very grateful to you for supporting SOROTEC. In the future, SOROTEC will continue to insist to develop good quality products, and promise to do our best to provide better services to you.

Thank you for visiting and wish SOROTEC a success in the next year.

For the solar power generation system users,the low cost, high reliability and long service life is the requirement of the solar inverter.

The requirements for the inverter are usually:
1.With a reasonable circuit structure, strict screening of components: have input DC polarity reverse connect, AC output short circuit, overheat overload and so on protection function.
2.Has a wide range of DC input voltage. Because the terminal voltage of the photovoltaic array varies with the load and the intensity of the sunlight, the inverter must be able to work in a wide range of DC input voltage adaptation range and ensure the stability of the AC output voltage.
3.As far as possible to reduce the use of intermediate (such as batteries, etc.) in order to save costs and improve efficiency.
