I found a potential suitable inverter UPS for 110VAC use

this is a bit too much for me to swallow as far as price but its an option.
I didnt know they made inverters with a built in UPS function, looks surprisingly sleek.

Ok I see now, I apologize, I was really struggling with the bad English in the ebay listings that came up when I searched "dioxin". It's an interesting little unit indeed. It does appear to combine the battery charger/inverter/relay all in one little neat package. I question the quality of the build (based mainly on physical size), but it very well could be a well built unit. As it is only available in 220 volt versions, it will be useless for any of us in the US.
It makes sense though, a 220v version would be significantly smaller in size than it's equivalent 120 volt version, as it would take twice the amperage in the 120v version to equal the same power output (watts) as the 220 v version. Higher amperage means higher heat and more expensive parts.
So, if dioxin where to make a 120 volt version of the same unit, what I am getting at is it would be larger, heavier, and more expensive. Just exactly how much so I am not sure, but if I were to ponder a guess, it would be slightly more expensive then the system Al has made here.

As long as quality only time will tell. It has been only two weeks since I put up the system so not talking about quality here, just specs.
Thanks for the Vid here! Question though... I see the battery with the power and ground leads going to the inverter as they should.. I see two power cords coming out of the inverter... Does this inverter act as the battery charger as well? and automatically switches to an inverter when the power goes down? Can you give me the model number off the inverter, sounds interesting.
Your system looks very well designed, including the tanks...one note for you though, generally you should not place a charger or inverter above a battery like that, especially so close to the ceiling... you can get explosive gasses that accumulate up there and a spark can easily set them off. Just a suggestion.
Best always,
al

Its going to depend on alot of things, the heater is going to be the biggest variable... If you can calculate out your power consumption and know the amp Hours of the Battery you can make a good estimate. I'll try and run a test latter this week on a 125 gal, 2 300 watt heaters, lights, and several aquaclear filters.

Actually only one power cord is coming out, the second one is coming in. Do not see it as an inverter, is causing a lot of confusion. It is a not conventional UPS without battery. After all a conventional UPS (from the computer world) is nothing more than an automatic DC/AC power inverter and a smart battery charger that usually carries a small 7.2 Amp 12V DC (it can be more than one in parallel) AGM battery inside, exactly what this thing is, except for the battery.
So yes, it is connected to the wall socket and while there is AC power it is a smart battery charger (this model 20 Amp). When there is a power outage it automatically kicks in and becomes an automatic DC / AC power inverter, a UPS. Once the AC power is restored the inverter part stops and the battery charger kicks in to recharge the battery.
It is a Doxin 1500W fully automatic DC / AC power inverter, UPS and battery charger. At least it can be read that way on the sticker. See in my previous post an eBay link and a warning about not being available for you guys in 110 - 120 VAC countries. Anyway I have found this eBay listing that claims it is a 110 VAC model but all the pictures are from the 220 VAC model, so be careful.
Serach eBay inverter charger ups 110 to see what its available to you. Quite expensive compared to these 220 VAC models by the way.
Thanks for your warning, I will consider it.
I would be curious to see how long your unit, as you currently have it set up, would run your tank. Is it possible to unplug the unit from the wall (simulating a power outage) and run a test?

Yes it is possible but it will have to be next weekend when I am home. I spend the day out at work Mon to Fri.
Cool, thanks!

Probably a good idea to do a test run of the backup anyway, prior to seeing what happens when the next big storm hits!
Ok here we go again. To make the test I did nothing special except to start a chronometer and write down on paper the battery voltage every hour. Running on the battery were two external canisters rated at 20 watts each, one inline 300 watts hydor heater, one eheim 250 watts submersible heater, a 35 watts air compressor and last a small 10 watts LED light.
00:00 -> 12.5 V
01:00 -> 12.5 V
02:00 -> 12.33 V
03:00 -> 12.17 V
04:00 -> 11.78 V
04:49 -> Unit complaint about low battery voltage, test finished.
Although I was not present at every minute I must say I never saw the 250 watts eheim heater kick in. The external hydor heater in the other hand was kicking in every fifteen or twenty minutes and every time it did the battery voltage went down for a full 0.5 V coming back up when it turned off.
So for less than five hour back up I am good to go but to tell the truth I am seriously thinking of buying a second battery to connect it in parallel.

Very helpful, thanks. can I ask what was the ambient temperature of the room the tank was in? Why I ask is that for some of us in a cold weather climate, this time could be greatly reduced.

There are a lot of diesel engines out there today. I ran my van 7/24 for 5 day after sandy for 750 gals. Water & no problems.inverters are great this way. Harry
