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%.

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.

Commercial UPS load is mostly the IT equipment need for AC power, so the product type for the typical AC output UPS, including backup type UPS, online interactive UPS and dual transformation online UPS, there are applications. Communication power supply (high frequency switching rectifier), which is widely used in telecommunication field, can be understood as a commercial UPS.
Industrial UPS product concept is more generalized, including both the AC output UPS and the DC output UPS, and even a variety of combination of product types. In different industrial areas, the proportion of AC UPS and DC UPS is not the same.
Even the UPS AC, industrial UPS technology is also mostly traditional silicon controlled rectifier +IGBT inverter technology structure. This traditional dual transform online UPS high reliability is widely recognized by industrial customers.

Inverter can not boot
1.The battery voltage is too low or the battery is damaged, to recharge or replace the battery.
2.The battery is not connected with the wire of the pure sine power inverter, please reconnect.
3.The positive and negative pole of the battery and the inverter is reversed, which leads to the fuse, replacing the fuse.

No output
1.Battery voltage is too low, recharge or replace the battery, check whether the wire connection is good.
2.Input voltage is too high, according to the rated input voltage of the pure sinewave inverter to adjust the appropriate input voltage.
3.Load power is greater than the nominal power of the inverter, use the inverter which power is less than the nominal power, or replace the inverter which nominal power is greater.
4.Inverter over temperature protection, the inverter is placed in a ventilated place to cool down for 15 minutes.
5.When using a small power consumption, the inverter fails to start, and the peak power of the inverter is larger than the load. Replacement of the inverter with greater peak power.

Inverter alarm
1.Under voltage alarm, the input voltage is too low, need to charge or replace the battery.
2.Over voltage alarm, input voltage is too high, change the appropriate input voltage.
3.Over temperature alarm, the inverter cool down for 15 minutes.
4.Overload alarm, turn off part of the load or the use of the load which power less than the nominal power of the inverter.

Battery usage time is too short
1.Electrical power consumption is too large, the replacement of large capacity battery.
2.Battery defective or damaged, replace the battery.
3.Battery charging is not enough, replace or charge the battery.
4.Attenuation of a wire, shorten the length of the wire or use a thicker wire.

Inverter can only drive small power load
Attenuation of a wire, shorten the length of the wire or use a thicker wire.

Low voltage DC power supply for safety
1.Low voltage DC power supply LED lighting safe and reliable.
2.Low voltage direct current low home power inverter drive home appliances, more safe.

Environmental protection and save electricity
1.One time investment, long service life.
2.More electricity consumption but save with inexhaustible solar energy.
3.Idle batteries can be recycled.

Anti-theft function
The home solar hybrid system has automatic light control function, automatic light in dark. If you use a timer or a controller, can be set on random time simulation in the house during the day, can automatically play music. Low voltage DC power supply LED lamp is lit or extinguished, or random light so that thieves can not judge whether there is someone in the house. Even if no one is relatively safe, it can avoid the phenomenon of people moving into the lives of people.

Keep the house clean
1.Low voltage direct current power supply driving small power inverter driven exhaust fan timing out the exhaust, the indoor harmful gas discharged outdoor.
2.Because there are air exhaust system in the house to exchange the outdoor air to reduce the window exhaust, the house is relatively clean.
