  • Oxygen concentrator power requirements.

    I just un-plugged my father's oxygen concentrator from the Kill-O-Watt. 4.42 kwh for a 12 hour period. The thing runs 24/7 so 8.82 for a 24 hour period. So far in searching the internet for specifications I have found that manufacturers don't advertise much in the way of power requirements. Hoping someone on the forum may have already researched this topic, and could provide some guidance.

    What sort of guidance? One that doesn't use such a whopping amount of power? That would be nice. That really is a lot of power use daily; no wonder they don't want to talk about it.

      Wow, that's a pretty heavy consumption, roughly 370 watts continuous. That's major for an off grid system. Over 8.8 Kwh/24 hours, that's enough to power perhaps 9 new full size Energy Star fridges! That sucks!

        Re: Oxygen concentrator power requirements.

        Since the units are basically air compressors you can see why it would be a big power user. Hard to compress any significant volume of air without using a lot of power, and then having to run it all the time ...

        I wonder if any supplier of these would mind if you brought along the Kill-A-Watt and measured a few in operation? If they were smart they'd see it as a selling feature; "this one uses the least energy for the volume of oxygen produced".

          Interesting info on how it works. Looks like considering what it does/how it operates, perhaps it's no wonder it sucks back on the power.

            There are some portable units out there. This thing is a dinosaur, and a rental at that. Maybe there has been some progress. I'll call up some medical supply stores and see if they have some info.

              Yeah. It has a compressor that doesn't ever shut down.

                  CPAP's are tiny compared to O2 concentrators. No comparison at all, other than they both move air somewhat.

                    you haven't mentioned what you have in mind with this info. are you on grid and just want backup power for it in case of an outage and if so then for how long? if you are looking at off the grid then as was said this is a huge draw of power constantly running and could compromise an offgrid pv system from supplying enough power for that and other items if not accounted for in the initial design.

                      Re: Oxygen concentrator power requirements.

                      For now I have grid power. So yes this is back-up, and I do have a generator. My current plan is for 8 to 10 280 watt panels facing due south. My shed is still under construction. I will be using a generator transfer switch panel to power selected circuits. The bottom line on the oxygen concentrator is to find a more efficient one. There are portable battery powered units available that can be operated on AC. I don't have any specific power consumption numbers on those yet. I hope to find on line operator manuals to get an idea. The portable units are expensive. The grid is pretty reliable here in southern KY. A typical outage would be from thunder storms or in the winter an occasional ice storm. We lost the grid a couple of years ago for 18 days due to ice.

                        Re: Oxygen concentrator power requirements.

                        I wonder if a couple days of O2 in tanks would be a better backup, than generators & fuel? If you have bad storms, solar is not effective if skys are cloudy or panels smashed up from falling ice.

                          We have O2 tanks. Ice storms are not the same as hail storms. An ice storm is the result of freezing rain. I read somewhere that a Midnight Solar Classic charge controller can be told to melt snow or ice off of the PV array. (I may have dreamed that)

                            I think there was talk about melting ice off of solar panels--But, so far, that has never been implemented (as far as I know--which is not very far ).

If you’re out of town, you can call in to the system to troubleshoot problems, and get it back in working order. If you have plenty of excess power, you can even turn on the snow-melting feature while you’re away. Remote control of Midnite power systems will be invaluable for installers, dealers and homeowners alike. "
