CYBERPOWER CST1500S UPS Sine Wave Battery Backup | In-depth Setup 

So wonderful to hear this video was helpful. Thank you for taking the time to watch and write.

Thank you for the info. We also added a whole house surge suppression, it better than doing nothing.

Todd, did you call Cyberpower as they come with 3yr warranty. I had a battery die and they replaced the entire unit. Best of luck.

@@cfldriven Yes I did, just my luck the warranty had expired just 3 months ago

@@gitarman666 I so hate when that happens.

JE, thank you for watching. Unplugging the PSU and the PC continuing to work only proves that the UPS is working correctly. To prove the it is a true sine wave output would require an oscilloscope. The reason for choosing this unit over others brands was true sine wave output, price, tech support, the amount of info avail on display monitor and warranty. You are correct about Costco selling both true sine wave and non true sine wave UPS, I almost bought the wrong one and had to go to Costco online for the correct version. As to issue of the glue failing and causing a fire there is no consumer recall and no conclusive proof there is an issue. The units are UL certified for safety. Good luck w your UPS search.

@@cfldriven thank you. I am going to buy the same model as you. CST1500S.

@@jesmpk2298 I have two of them and would definitely recommend it. I think of it as insurance for my electronics.

If you set the display to off, it will come on to indicate power is out and it can also be set to give an audio alarm. Thank you for watching Ganery.

Yes that would be the normal function, but on this one the switch was defective and I had to use the software to muted. It wasn't enough of an issue to send it back. Thanks for watching.

So far no issues.

If I understood correctly this unit will accept plugs with only two blades and no grounding pin.

This UPS has a Energy Star rating due in part to "GreenPower UPS Bypass Design". Under normal use utility power bypasses the transformer thus reducing noise, heat and energy use. This is a built-in feature and can not by disabled. Help this info helps. Thank you for watching.

@@cfldriven Can you please tell me if I turn off my computer but still have my monitor on in standby mode, will this UPS turn off my monitor due to low load? Or if I put my PC into let's say sleep mode, won't it turn off my PC the wrong way?

@@CHarvelCHannel The reason to have your PC on UPS is during a power outage while your pc is running unattended (rendering, uploading, etc) the UPS when connected to the PC will safely shut it down. If the pc is in sleep there no way for the ups to communicate with it. I have two monitors and only the main one is on the ups, the other is just on the surge side of ups. If you leave monitor in standby mode it will continue to receive power until the battery runs-down.

@@cfldriven That is, the monitor will receive power from the battery even if the UPS is plugged into an outlet? That is, the monitor will be forced to be powered from the UPS battery? Accordingly, if my computer is in sleep mode, can the UPS consider that the computer is turned off and force it to shut down? This is terrible.

@@CHarvelCHannel When the utility power is lost anything plugged to the battery side of the ups will be powered until the battery runs out or the utility comes on. You could just turn off the computer and monitor instead of using the sleep mode.

Samantha, you are correct muting will only occur through the software or by pressing for 2 seconds. Briefly pressing the mute button only cycles the display through the various power status. Thank you for pointing this out.

The unit rounds off to the nearest watt with no decimal point.

@@cfldriven Thanks for confirming. I have an older CP1500PFCLCD with the non-color display that only shows in 8 or 9 watt increments. Interestingly, the same model # now shows a color display on cyberpower's web site. You'd think they'd use a different model # for newer units, or something to designate a version update. Doubt it's software related.

@@geepeezee5030 I'm looking to pick up another one at Costco, cheaper in the store than online, so I see if I get a color display. I prefer input voltage reading as at a glance I can tell if the grid is down or oscillating. Thank you for sharing.

@@cfldriven No stores around here have 'em. Online only item. Also, you might consider powerpanel business.. It's superior to the person edition. I'd stick with version 3.xx if running windows. 4.x has a bug where it will not execute the defined script on a power event. Don't ask how I know this.

I wish vendors would stop using product boxes as shipping boxes, most of the ones I get don't survive and have to be returned for a replacement.

Garth, thank you for that great reminder. In our case the Rheem tankless draws less than 2 amps which is well within the limits of the CyberPower. One should always compare the amp and wattage draw of all devices to make sure they don't exceed what the power supply can safely handle.

@@cfldriven thought it might have been a joke. Hard to believe that under a load of so much immediate heat/energy (enough for a hot shower) only 2 amps is drawn. Double digit power draw, amps, while under load is not uncommon with most tankless water heaters. Some over larger systems can peak in the triple digits. You must have an efficient unit. Or possibly 2 amps is only while at idle?? Be safe.

@@garthzader I should clarify our Rheem tankless runs on natural gas so the power draw is just for the blower and electronics. Now the electric version of the same unit has a huge power draw as you have noted.

@@cfldriven ahh, that sounds right. Thanks for the clarification!

@@garthzader Yes, now 2 amps make sense.

Modified Sine Wave (quasi-sine): A modified sine wave inverter, or quasi-sine wave inverter, actually has a waveform more like a square wave but with an extra step.
