How to buy a suitable UPS that you need?
If you want to buy a UPS that suits your needs, you have to consider many factors, the most important of which is to determine the power of the UPS, and then determine the type of UPS according to the load and grid environment.
UPS types are divided into: online UPS, interactive UPS, Backup UPS. Choose the installation method according to the use environment, tower UPS and rack UPS.
These are several more important factors. Others can also consider the manufacturer’s service capacity, battery life, etc. I think the right choice The power of the UPS is very important, because if the occasion is small, a high-power UPS will be wasted. For small occasions such as an office or one or two servers, a small power is enough, and there is no need to use too much power.
Now there are many brands of low-power UPS available, and various manufacturers have corresponding products. For example, UPSEN has several Online UPS like: DC UPS, Queen Star, Century Star these models, the cost performance is reasonable, the reliability and environmental adaptability are also really good.
Notes for using lead acid battery
How to improve the reliability of UPS ?
- Add parallel battery packs：UPS using a single set of series batteries are more risky for normal power supply loads.
When connected in series, if there is a problem with one battery, it will affect the discharge of the entire battery pack, which will cause the UPS to fail to supply power.
When connected in parallel, if one of the battery packs fails, but the UPS can still be powered by another normal battery pack for a period of time, so that there is time to connect the standby generator to supply power or time to shut down the load device.
- The installation of diesel generators: battery power can only solve the urgent need for a moment.
If you face a long power outage, even the longest battery pack may not work. Therefore, in the case of a long power outage, it is desirable to use a diesel generator as a backup power supply.
- Increase availability by installing an UPS
Redundant design logic not only applies to power protection schemes, but also to UPS designs. Building multiple power paths in a power supply design can radically improve system reliability.
How do I determine the Total Backup Time?
For a fixed load, the total backup time is determined by the capacity of the batteries installed. The type of batteries (& their condition) will also have an effect on the backup time. Different batteries may have similar amp-hour ratings, but may differ in their performance. One key factor is the rated depth of discharge of the battery (ie how deep can the battery safely discharge without getting damaged). This can vary from about 20% to about 80% for the best batteries.
How Solar Inverters Work?
Most solar photovoltaic (PV) systems can't function without an inverter, but what are inverters, really? Essentially, an inverter is a large component within the solar system that converts direct current (DC) electricity into alternating current (AC) electricity. It also provides real-time net metering, sends information to the remote monitoring system and regulates whether a building’s energy is drawn from the solar panels or the local utility company.
What is the difference between modified sine wave and pure sine wave?
Inverters have either modified sine wave (square wave) or pure sine wave output.
Pure Sine wave Inverter
This is the best output waveform you can get out of an inverter and all appliances are able to run off it without interference or overheating. Some of its advantages are as follows:
Modified Sine wave Inverter
The Modified sine wave inverter has limitations. These are some of the appliances that may experience problems when running off Modified Sine wave inverters:
It is definitely advantageous to use a pure sine wave inverter as a pure sine wave inverter can basically run any type of equipment in contrast to a modified sine wave / step square wave inverter.
USING A LASER PRINTER WITH A POWER INVERTER
A laser printer generally requires a pure sine wave inverter capable of producing at least 3 times the continuous wattage rating of the printer. For instance, a laser printer rated at 500 watts requires an inverter rated at 1500 watts continuous or higher.
An inkjet printer does not maintain the same requirements as a laser printer. Inkjet printers can be operated normally with a modified sine wave inverter rated to handle the printers wattage requirement.
What are the two major functions of UPS?
Two major features of UPS:
1. Emergency use: Prevent accidental power outages that affect normal work.
2. Regular daily use: eliminate power surges, instantaneous high voltage, instantaneous low-voltage, wire noise and frequency offset, such as pollution, improve power quality, provide high-quality power supply.
The use of our high quality UPSEN UPS power products can solve two common aspects of the problems accidental power outages and poor quality of mains can cause.
Our superior online UPS, has the latest three-level inverter control technology, DSP+IGBT technology, dual-transform on-line, emergency power off function and more.
Our UPS power supply products can provide timely power supply, to ensure data protection and unhindered work.
For UPS usage of major functions, UPSEN will provide UPS safety and handling training experience for new and old customers to learn:
1. How to avoid battery depth discharge caused by light loads, reducing the battery service life.
2. How proper discharge is helpful to the care of the battery, and how to prolong battery life.
3. How small UPS products can be used in work environments safely, and the correct manner of product storage.
