The importance of finding the right energy storage system for your UPS

energy storage system for your UPS

Uninterruptible power systems (UPS) have important functions in protecting power, but their primary task is to maintain a reliable power supply in the event of a grid failure or overload. In order for the UPS to accomplish this task, it needs a reliable power source that is stored in a safe location and is immediately available when needed. Dry batteries as energy storage are a popular choice because they are more environmentally friendly.

Power source options for an inverter

Kinetic energy is stored mechanically in flywheels. Electricity from the grid powers a motor generator that spins the flywheel and stores the energy. In the event of a power failure, this energy is converted back into electrical energy and fed into the inverter. Flywheels provide a limited reserve of 30-45 seconds, which is their main problem. For many companies, this is not enough time. Nor are they as economical as lead-acid batteries.

Hydrogen gas into electrical energy

A chemical reaction using hydrogen as a fuel produces electricity by converting hydrogen gas into electrical energy. Hydrogen fuel cells are environmentally friendly because their only product is water, but they require energy from the opposite source. Fuel cells are much more expensive than batteries and more dangerous because hydrogen is an explosive gas.

Lithium-ion batteries

It can be used as a backup for an inverter. Lithium-ion batteries are small and light compared to lead-acid batteries. But they are expensive compared to lead-acid batteries and can explode if overheated. Their small size and ability to deliver high power densities make them attractive to electric vehicle developers. As a result, a lot of time is now spent developing safer and less expensive versions.

Maintaining the UPS battery (energy storage)

The first thing you need to do to keep your batteries healthy is to maintain their ambient temperature. You can visually inspect the batteries for corrosion and leaks and tighten the terminals if necessary. UPS batteries should be tested to get a better idea of their condition and future life. Impedance testing is simple and can predict the end of life of batteries while they are still being charged.

The available capacity of the battery can be determined by a load test. In this case, the batteries must be discharged, which can shorten their life. This method is a last resort, as the critical load must be maintained by other means during the load bank test. This may require renting ups and using other parts of the ups, such as the APC 1500 battery.

Battery backup breakdown

Everyone in the office is having a great time as the lights dim, flicker, and then….. CUT-OUT!

Yes, that’s right, you just had a power outage. It could be an ice storm, a thunderstorm, a tornado, a car hitting a power pole, or maybe the power company just cut the power to do some work on the lines. No problem, your server is connected to a UPS, an uninterruptible power supply. The battery life is sufficient to power the server until the power is restored… or is it? You enter the computer room and immediately notice an eerie silence. The network switch isn’t humming, the air conditioning is silent, and ….. THE SERVER IS DOWN!

Loss of data

You wait for the power to come back on, then confidently flip the server switch. The server starts. You see the Windows logo. Then… nothing. The server seems to be stuck, or you get a message that files are missing or corrupted. You turn the server off and on again, with the same result. Faced with growing panic and staff inaction, you make one last attempt.

Then comes the “Oh no!” moment.

Isn’t the UPS supposed to protect against power outages? Why is my server down?

Why are my files corrupted or worse? Your UPS, which you thought was protecting your server, is no longer holding its battery charge. UPS batteries wear out over time. Their life span depends on the electrical environment. In a “clean” environment where there are few power surges, outages, or interruptions, the battery will last a long time. In a “dirty” environment, where the UPS power supply is unstable, the battery will wear out much faster. This is often the case in the manufacturing industry, where energy-intensive equipment causes large fluctuations in the grid voltage.

In fact, an inverter “takes the bullet” to protect the equipment connected to it, much like a Secret Service agent takes a bullet for the president. The UPS is designed to be sacrificed to protect your valuable equipment and data.

How do you know how old your battery is?

If you keep good records and are diligent, after three years, just look at the calendar and you will find an entry for UPS or battery replacement. That’s right! Everyone else can install UPS monitoring software that alerts us when it’s necessary.

Use a high-quality UPS

My advice is to use a high-quality UPS designed to protect servers. Personally, I prefer APC UPSs. Most server-class units have hot-swappable batteries. You don’t even have to shut down the server to change the battery. When you buy a replacement battery, pack the old battery in the same box as the new one and send it back to APC for recycling. APC will even pay for the return shipping!

Replacement of battery

In addition to the battery, other UPS components can also wear out, especially in a “dirty” grid environment. Therefore, I recommend replacing the battery every 3-4 years and then replacing the entire UPS. Note that there may be exceptions to this rule for some high-end UPSs, such as the large rackmount units used in data centers.

And another tip:

Always use replacement batteries certified by your UPS manufacturer. Don’t use third-party batteries. They’re cheaper, but will they protect you when you need them? Isn’t it worth it to keep your peace of mind? How old is your UPS battery? If it’s over three years old, you should consider replacing the battery or UPS. If it is more than four years old, you should replace the battery NOW.

Batteries (energy storage) for an active world

FACTS: In 1978, Alessandro Volta developed the first battery. In 1859, Gaston Plante invented the first battery, which is still used in cars today. Since then, many improvements have been made to solve various problems. One of them is the sudden failure of the input power supply. This costs a lot of money due to severe business interruptions or data loss. Even worse is the high probability of injury and death due to power outages. You’ve probably had to turn in a report to your boss in 30 minutes, lost a game in your favorite app, or been stuck for a few minutes in a place you don’t want to be. The culprit: an unexpected power outage.

UPS Battery

An uninterruptible power supply (UPS) is a device that can protect equipment from general power problems. The function of UPS batteries is to provide enough backup power to properly shut down equipment. They are like lifeblood called air that sustains the day-to-day operations of industry, including telecommunications, data centers, and hospitals. UPS batteries come in different sizes. They can be single units that protect your personal computer or a group of computers or large units that keep data centers, billion-dollar skyscrapers, and even cities running.

Rectifier and Charger

UPS devices provide protection against power outages. In normal operation, these devices consist of three components: a rectifier, an inverter, and a battery. A rectifier is a component whose role is to conduct electricity in one direction. This device converts alternating current (AC) – current flowing in one direction – to direct current (DC) – current flowing in one direction. The DC output then feeds the battery. An inverter works the other way around: it converts direct current into alternating current and powers the appliances. Using the energy stored in the battery by the charging rectifier, the inverter provides continuous power to the appliances for a set period of time in the event of a power failure.

Deep cycle battery

Deep cycle batteries are used to power forklifts, sweepers, energy storage systems, recreational vehicles and boats, traffic lights, etc. A deep cycle battery is another example of a lead-acid battery designed to discharge up to 80 percent. Although they have some similarities, car batteries and deep cycle batteries have their own limitations. A car battery is designed to provide power spikes for short periods of time, while a deep cycle battery is designed to provide stable power over a longer period of time. Although the battery is designed for repeated deep discharges, a deep cycle battery will eventually need to be replaced.

Sudden power outages? Your equipment needs to be protected against this, especially if many people depend on it. An uninterruptible power supply or UPS battery provides enough backup power to properly shut down your equipment. There is also a rectifier battery, a device that converts alternating current (AC) to direct current (DC), which is then fed into the battery. A deep cycle battery is designed to provide a stable current that lasts longer than a car battery.
