How to determine the UPS power of energy storage lead-acid battery

　　How to determine the power of the energy storage lead-acid battery UPS power supply

　　1, determine the type of UPS required

　　1 ) According to the load's requirements for output stability, switching time, and output waveform, it is determined whether to choose online, online interactive, backup, sine wave, square wave and other types of UPS. The output stability and instant response capability of the online UPS are stronger than the other two, and it is also more adaptable to non-linear loads and inductive loads. On-line UPS is required for some more sophisticated equipment and more important equipment. In some areas where the mains power fluctuation range is relatively large, avoid the use of interactive and backup methods. If you want to use a generator with a short delay UPS, online UPS is recommended.

　　 2) As the basic power supply equipment, the most important thing for UPS is reliability. Generally speaking, the MTBF (mean time between failures) of a higher-power UPS is much higher than that of a low-power UPS. Therefore, from the perspective of reliability, a UPS with a higher power should be selected.

　　3) From the perspective of investment cost or capacity expansion, it is recommended that users take a one-time investment and one-time approach based on construction funds, business development in the next 3 to 5 years, etc. ; Or build while growing, and choose UPS power supplies that can be upgraded and expanded to avoid repeated investment losses due to insufficient funds or inadequate business development forecasts.

　　2, determine the required UPS power capacity

　　 If there is no special industry standard requirements, it is recommended to consider the following scheme ：

　　1), calculate the sum of all loads (Su003dS1+S2+……+Sn), unit: VA; UPS capacity ≥ S ÷ 0.8 (considering UPS Impact resistance and expansion requirements)

　　2), the backup full-load power supply time is not less than 30 minutes.

　　 After determining the power value of the UPS power supply, the standby time of the UPS needs to be considered: standard type, standby time is 5-10 minutes; long delay, standby time is 1 ~8 hours to ensure long-term operation; any configuration can be customized according to the special needs of users.

　　3. Consider the performance of power failure protection and the backup time of the battery

　　UPS power supply can be divided according to the standby time Standard type and long time delay type. The standby time of the standard UPS is 5-15 minutes, and the long-term UPS is 1-8 hours, or even longer. If you only need to save and exit after the power supply of the equipment is interrupted, it is recommended to use a standard UPS; if your equipment still needs to operate for a long time when the power is cut off, you must use a long-term UPS.

　　4. Additional battery functions

　　 In order to improve the reliability of the system, it is recommended to use a UPS hot backup system, which can be considered in series Hot backup or parallel hot backup. The small capacity UPS (1～2KVA) can also choose the redundant switch. You can choose a remote monitoring panel to monitor and control the UPS remotely. The monitoring software can be selected to realize the intelligent management between the computer and the UPS. You can choose a network adapter to realize UPS network management (based on SNMP). In some rainy and thunderous areas, lightning protection devices can be used. Also consider whether the network can be used and peripherals can be protected. Because peripherals are becoming more and more complete (such as printers, scanners), this part of the equipment also needs to be protected. Does it have cable line surge protection and data line surge protection functions? Is it possible to automatically shut down the system when unattended? In addition, because the user’s commercial desktop UPS is mostly at his side, the product design style, The manufacturing process also needs to be considered.

　　5. Battery service capability

　　 Each user’s network characteristics and power environment are different, and power protection requirements are also different. Change accordingly. The various problems that users may encounter when using UPS are not the same. Users hope to purchase products and services that are fully suitable for actual needs, and care about the short-term and long-term return rates of equipment investment and investment risks. The reality is that most users lack professionals in this area. Therefore, a high-quality service system and an active service attitude have become an important factor that users must consider when purchasing UPS power supplies. Contact: 18038382979
