I'm quite a fan of your video tutorials. But in this one, one point is not entirely correct: double conversion UPS are not the most efficient version, quite the opposite. They offer the best power quality, since there is no interruption at all and the AC is newly generated, so no variations or harmonics from the grid are getting to the equipment. Even the frequency can be corrected or changed from 50 to 60Hz of needed. But this process of double conversion is not the most efficient, since it has permanently the losses of an AC-DC conversion plus the losses of a DC-AC conversion. A UPS with transfer switch has very little loses, as under normal operation no conversion is occurring. But you get all the power quality problems from the grid to the load. And you can not influence the frequency.
Thank you for your comments. You are correct about the differences in efficiency (~96% for line-interactive, ~90% for double-conversion), but this is rarely the decision point for selecting one over the other. As you indicated, there are specific advantages to the double-conversion design, which are necessary in particular applications. Both UPS designs provide efficient operation; >90% efficiency is very good for any electrical device.
Thank you for your kind words @maheralrawashdeh1204! We're glad you found the content clear and helpful. We appreciate your suggestion and will definitely consider creating a video about how solar inverters work. Stay tuned for updates, and if you have any other topics you'd like us to cover, feel free to let us know!
Sizing of UPS systems is based on load and required time for supplying backup power. A simple way to do this is to add up the loads (in VA or Watts) of all connected equipment and multiply by 1.2. Then go a UPS manufacturer's website and select a UPS that will output at least the total load that was calculated. Then, decide how many minutes of backup power is required, and select the desired model from the data given by the manufacturer. Most manufacturers can help you do the calculation, and many have "calculators" on their websites.
THe animation shows a dirty sine at the source, and a clean sine at the output. Do all of these UPS types provide a clean sinewave by nature or is that another feature that some UPS devices may or may not provide?
Hello, @PspiralifeTutorials. Thank you for your question. Yes, it should be clear on the output side. All good and industrial UPS devices should provide a clean output power source because they protect expensive devices on the output side. Happy learning from RealPars!
My co-workers at my job let me have a UPS battery like this to hook up my TV, game console, and Blu-Ray player at home for my own personal enjoyments in case the power goes out. I have a TrippLite Internet Office 550VA Ultra-Compact Standby 120V UPS, and got me wondering how long it lasts when the power goes down.
Thanks for your comment and topic suggestion! We don't have a video covering that at the moment, but I will happily pass this on to our course developers. Thanks again for sharing and happy learning!
Most laptops have a built in battery that acts as a UPS. A small office-grade UPS is a standby (offline) UPS which kicks in when the main AC power is lost.
An ups battery will burn for 3 days non stop if it has a minor problem. So extreme caution should be taken when using them. Similarly big computers. The fire cannot be stopped because it is an electric dc shot circuit. At least 50 metres gaps are required for usage. Any DC system is like that. Some of them can burst to a range of 2 miles. Similarly huge TVs. Don't ask me why again and again.
A UPS has one or more rechargeable batteries inside. These batteries typically last 2-4 years, at which time, they need to be replaced. The batteries are modular and can be removed and replaced fairly easily. Most can be recycled.
Hello, @joshuachu2445. Thank you for your question. Yes, you can, provided your extension cord meets the wattage requirements as your UPS's spec sheet requires. Ensure you stay within the length needed in the UPS manual and your local electrical codes. Happy learning from REALPARS!
do standby USPs provide any additional protection from surges, voltage drops and instable supply for the load, in other words, could it be used as a protection means?
Hi Hamza, Thank you for your question. Yes, it can. But UPS power, depending on your load, will be limited until the batteries die. Regular UPS for backup use at home will last about 30 minutes. Many date servers have more significant UPS that can last as much as 2 hours. Those types of systems have a generator to back up the UPS.
@@realpars my question is about the case where the standby UPS is standing by, and the power is coming from the mains and not the battery, does the standby UPS provide any protection in this case?
UPS systems will charge when the source of electricity is available. When the electricity source is interrupted, the circuit will automatically switch to provide stored power from the battery.
@@realpars Actually I wanted to know does the UPS need to charge separately by switching off the UPS power button or it is charged automatically while it is connected to power source???
The UPS should be plugged in whenever the PC is powered on. If you power off the PC, you can power off the UPS, but you want to make sure the UPS is fully charged again before relying on it to provide backup power for the PC.
As we stated in our video, you can have more than one UPS as a backup in your data center, protecting your data servers. The transfer switch is normally used on the AC side with generators and the utility power line coming into your plant. You can have more than one generator in parallel, too, depending on your engineering design and risk factors of power loss.
The battery charger shown in the video is a rectifier (definition of a battery charger). Thank you for pointing that out, as other readers may find this information useful!
You don't need to, but since UPS devices do draw current even when no loads are connected, you probably would want to. By the same token, UPS's have batteries which should not be allowed to fully discharge and set idle for long periods of time.
Yes. The UPS would be recharged from of the electricity that is produced by the solar system. UPS's sized to power a modest home or cabin are not too large, but can be expensive. A 1500W UPS can cost up to $3000. If you have a refrigerator, TV or electric water heater or stove in the off-grid dwelling, you may need a much large unit or multiple units if these need to be operated during "dark" hours.
What about the power consumption of those three types of UPS? I have a 1Kav Online UPS and when I check with an energy monitor I feel it consume more electricity than it should be.
Every type of UPS consumes some power, even when not connected to the battery supply. On-line UPS systems, by their design, provide the highest level of protection against power loss but exhibit some power consumption during normal operation. If your "losses" are >10%, then there may be an issue with the incoming power (cycle variations, "dirty" waveform, etc.) that is switching your system to battery in order to maintain a "clean" power feed.
The number of devices that are backed up by a UPS is not an important factor. The total connected load and the amount of time you desire the UPS to back up the load in case of a power failure is what is important. Of course, depending on the number of devices, you will need to have the means to plug in or connect all of the backed-up devices. In your case, an appropriately sized standby UPS wired directly to a set of distribution panels with either appropriately-placed hardwired or plug-in outlets would be recommended.
@@realpars I'm trying to build a project for where I work . I get constant power fluctuations and outages, worse these types of UPS are not easily available. So I'm having hard time to find it.

I'm interested in purchasing online ups for sound equipment, is it the right choice?
I just realized that all cell phones and laptops are technically a UPS since it allows uninterrupted switching between battery and incoming power.
No they are not. A ups supply AC power to another piece of equipment.
No they are not, at all
I work on these and this is exactly how I explain how they work... it's the concept
@@bonesredlight You're probably the only person in the comments that isn't 12 explaining how things work.
