1. Reasonable selection of installation position

A good installation position is very important. The place where UPS is placed must have good ventilation effect, away from water, combustible gas and corrosive agent, and the ambient temperature should be kept between 0 ~ 40 ℃. If the UPS is disassembled and used at low temperature, there may be water droplets condensation. Once the ambient temperature exceeds 25 degrees, the battery life will be shortened by half for every 10 degrees increase. At present, the storage batteries used in ups are generally maintenance free sealed lead-acid batteries, and the design life is generally 5 years.
The UPS power supply should not be placed on the side, and the air inlet and outlet holes should be kept unobstructed. When the load is connected with the UPS power supply, the load must be turned off first, then the wiring is connected, and then the load is opened one by one. It is strictly forbidden to connect the electric load, copier and other inductive loads into the ups to avoid injury. When the UPS is connected to a special socket with over-current protection device, the power socket used should be connected to the protective grounding end; whether the input power line is inserted into the utility socket or not, the ups output may be charged. In order to make UPS without output, it is necessary to turn off the switch first, and then cancel the power supply.

2. Skills of first charging

After the new UPS power supply is purchased, the ups should be inserted into the 220 V municipal power grid for at least 12 hours to ensure that the battery is fully charged. Otherwise, the actual usable capacity of the battery will be much lower than the nominal capacity of the battery. If UPS is not used for a long time. The ups should be started for 24 hours every 2-3 months to make it fully charged, and the UPS power supply should be kept in the inverter working state for 2-3 minutes to ensure the normal life of the battery. Once the UPS power supply is connected to the mains power supply, it starts to charge the battery pack. Press the power on key for more than 1 second to start the inverter.

3. UPS should not be idle for a long time

The excessive discharge and long-term open circuit idle of the battery can increase the internal resistance of the battery and deteriorate the charging and discharging performance. For long-term idle UPS power supply, before restarting, make the UPS power supply use the charging circuit in the machine to charge for 12 hours, and then connect the load. For the backup UPS power supply, it is better to keep the UPS power in the inverter state for 2-3 minutes every other month to activate the storage battery. In addition, it is also necessary to strictly control the charging current of the battery to not exceed the maximum allowable charging current of the battery. Because excessive charging current will shorten the service life of the battery.

4. Startup and shutdown sequence when using UPS

The correct startup and shutdown sequence should be to turn on the ups to supply power to it, and then turn on each load, so as to avoid the damage to UPS caused by the instantaneous current impact when starting. The sequence of power-off is just the opposite. Each load should be shut down first and then the ups should be turned off. When the power supply is interrupted by UPS, you should save your own data and data as soon as possible, and then turn off the computer. Otherwise, the use of UPS power supply may cause excessive discharge of UPS, thus shortening the service life of ups.

5. Avoid overload

When using UPS, the size of the load should be calculated to avoid the load being too large or too small. Too large load will make ups work in overload state for a long time, so as to shorten the service life of ups. If the load is too small, the working circuit of ups will work in abnormal state for a long time, which is also harmful to UPS. Reasonable load should be controlled between 50% and 80%. Practice has proved that the best output load control of UPS is about 60%, and the reliability is the best. In case of overload or inverter failure, ups will switch to bypass mode. At this time, UPS has no backup function, and the power supply for load is directly supplied by power system.

1.Use of AC voltage regulator
After using UPS power supply, there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load.

2.Battery balanced charging skills
At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is 10.5 V; for 24 V batteries, the final discharge voltage is 21 V; for 96 V batteries, the discharge calibration voltage is 85 v. The battery is not charged in time after discharge; the battery is idle for a long time. When the power supply is interrupted, the battery with continuous floating charge will release nearly half of its capacity.

3.Do not use diesel generators
UPS should not be powered by diesel generator because its frequency is often unstable, which affects the normal operation of ups.

4.Pay attention to the safe operation of operators
When connecting the output power supply to UPS, attention should also be paid to safety. Since the output voltage and current of ups are relatively large, it is necessary to pay attention to safety when connecting the output power supply to prevent the occurrence of electric shock accidents.
When replacing the battery, turn off the UPS power supply and disconnect from the mains power supply. Use a screwdriver with insulated handle. Do not put tools or other metal objects on the battery. When connecting the battery cable, it is normal to have small sparks at the connector, which will not harm personal safety and UPS power supply. Do not short circuit or reverse connect the positive and negative electrodes of the battery. When replacing the battery, it is not suitable to replace it partly, but to replace it as a whole. In addition, it is forbidden to use batteries with different amperage and different brands.

5.Real time monitoring
At present, all intelligent UPS have operability characteristics such as communication with microcomputer and program control. When the corresponding software is installed on the microcomputer and connected to UPS through serial / parallel port, the program can be used to communicate with ups. Generally, it has the functions of information inquiry, parameter setting, timing setting, automatic shutdown and alarm. Then, the UPS is connected to the computer through the special serial port control cable, and then through RS232 and RS485 protocol communication, the ups can automatically shut down when there is no mains power input and the power is low. It can monitor multiple UPS connected to multiple serial ports at the same time. Among them, through RS232 protocol, a serial port can only connect one UPS, through RS485 protocol, a serial port can connect 256 ups at most.

On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair.

Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging.

Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products.

In this exhibition, Sorotec‘s products have attracted many customers and been widely praised. Especially Revo II. Revo II is a hybrid pure sine wave solar inverter. Its particular touch screen makes it more convenient to operate. It can parallel up to 9 pcs. The maximum power is 49.5KW. It has four working modes. Especially in the “Solar+AC” working mode, the solar and AC mains can charge the battery and power the loads together. It is the maximum use of the solar energy. The solar energy utilization is over 15% than other solar inverter. Revo series can start and work without battery, and also can work with lithium battery. This product has a strong comprehensive competitiveness.

Sorotec not only has the most advanced scientific research technology in the field. The products are of high gold content. And Sorotec is willing to accept and create new things. This has been unanimously recognized by all customers.

Due to the high integration, compact overall structure and large heat dissipation, the hybrid inverter requires high temperature, humidity and dust content in the installation environment. When installing the solar inverter, it must provide a good operating environment for the inverter. The working ambient temperature of the inverter is rated at 40 ℃. If the ambient temperature is higher than 40 ℃ ~ 50 ℃, the rated current must be reduced. Otherwise, the temperature rise of the device will be too high, which will increase the possibility of device damage (especially IGBT power module), and have a great impact on normal and safe operation. If the working environment of the inverter fails to meet the requirements of the inverter on the working environment, it will cause high failure rate of the inverter, affect the long-term, reliable and safe operation, resulting in unnecessary economic losses. Therefore, the following matters should be paid attention to in the application of the inverter.

1.Operating temperature.

The inside of the inverter is a high-power electronic component, which is easily affected by the working temperature. The product is generally required to be 0-55 ℃, but in order to ensure the safety and reliability of the work, it should be considered to leave room for use, preferably controlled below 40 ℃. If the inverter is installed in the inverter cabinet, it shall be installed on the upper part of the cabinet and strictly comply with the installation requirements in the product manual. It is absolutely not allowed to install the heating element or the element easy to heat against the bottom of the inverter.

2.Ambient temperature.

When the temperature is too high and the temperature changes greatly, condensation is easy to occur inside the inverter, and its insulation performance will be greatly reduced, or even lead to short circuit accidents. If necessary, desiccant and heater must be added to the inverter cabinet. The surrounding humidity of the inverter shall be below 90%. If the surrounding humidity is too high, the electrical insulation will be reduced and the metal part will be corroded. If restricted by the installation site, the inverter shall not be installed in a place with high humidity, and the cabinet of the inverter shall be sealed as far as possible. In order to prevent condensation when the inverter stops, a convection heater should be added.

3.Corrosive gas.

If the concentration of corrosive gas is large, it will not only corrode the leads and printed circuit boards of components, but also accelerate the aging of plastic components and reduce the insulation performance. In this case, the inverter cabinet should be made into a closed structure and air exchange. There shall be no corrosive, explosive or combustible gas, dust and oil mist around the inverter. If there are explosive and combustible gases in the surrounding environment where the inverter is installed, there are relays and contactors that are easy to generate sparks in the inverter, so fire or explosion accidents may be caused sometimes. If there is dust and oil mist around the inverter, its adhesion and accumulation in the inverter will lead to the decrease of insulation; for the inverter with forced air cooling, the temperature in the inverter will rise abnormally due to the filter blockage, so that the inverter cannot operate stably.

4.Vibration and shock.

When the inverter cabinet is subject to mechanical vibration and impact, it will cause poor electrical contact. At this time, in addition to improving the mechanical strength of the inverter cabinet, away from the vibration source and impact source, the anti-seismic rubber pad shall be used to fix the inverter cabinet and electromagnetic switch and other components that generate vibration. The vibration resistance of the inverter should be different in different types. When the vibration exceeds the allowable value of the inverter, the fastening part of the components will be loose and the relay and contactor will act wrongly, which often leads to the unstable operation of the inverter. For the vibration situation that can be foreseen in advance, the vibration of inverter should be fully considered.

5.The altitude of inverter application is usually below 1000m.

If the altitude is high, the air pressure will be high, which is easy to cause insulation damage. In addition, the cooling effect of high elevation also decreases, so it is necessary to pay attention to the temperature rise of inverter.
