UPS HACK Solar Power and Wind Turbine DIY.
By
I bought a UPS by APC what a great add on to solar and wind turbine setup. I will keep you posted on how it works out.
This is sound advice and so important

@UNLIMITED1488 The APC does it for me.

@Aleziss It dose good. I stress tested the APC when I first got it I ran a 1200W space heater for 2hrs and watched the super bowl and it charded back up fine.

@jerjanerayo It is. That is a great inverter I dont use it because it charges the batterys any time its connected to the grid.

how does the apc handle the charge for these batteries ? They are a lot bigger than the original ones. Is it able to charge properly ?

@OBXSOLWIND is that white box voyager is a transformer based inverter?

So how do you charge your 48v battery bank with your 12v system?

@davevanden1 Your right I am very inpressed with the UPS. I now have run designated cicuits to my office and entertainment equipment.
Thanks for the comment.

@MrLagros
you say they are going bad?
if they are smart ups”s and there is a bad battery they will not work
i just had a customer give me two units cause they said they didnt work threw new batteries on them presto good as new lol it takes quite a bit to kill these units they also have a great surge protector built in

the good thing with these ups ‘s is the smart ups has cold start function the regular ones dont.
the small ones are 12 volt the 750 is 24 volt then they jump up to 48 volt this is what i am using for my inverter it works great and pure sine wave and the beauty of it I can give my batteries a good solid charge every so often keeps them equal

@OBXSOLWIND I’m guessing you mean 50-80? I guess that’s not too bad, maybe a little less than what a commercial sine wave inverter/charger would give you (maybe the same, probably depends on load). Pretty neat!

@linuxpyro I dont know the efficiency. I would guess 5 to 8 percent and yes it is a pure sine wave inverter.

That’s a pretty neat hack. What’s the efficiency like on it? Also, is the output a sine wave?

VERY NICE. THANKS

@OBXSOLWIND That’s exactly what I was thinking. Since I have two entirely seperate circuits, I was thinking about setting an APC on the circuit that will run my computer, and have everything else on the modified sine circuit. I would be running it at about one third capacity also.

Thanks Skiipy.
I just want everv one to be cautious with these things because we are asking them to do somthing they are not realy ment to do. I bought a large one for this reason. I am planning to only run it at about a third of its capacity.
Have fun but be safe.

I think I may have answerd you Q on your video you just made.
September 24th, 2010 at 2:23 am
Kevin, that is awesome. I am scouting around for one of these right now.

I tryed running my Apc in to my Xatrex 300wat the apc relays just claderd it didnt whant to work right.
September 24th, 2010 at 3:58 am
Mr Lagros
That is a great question. I have thought of this and I will test it. It dose say on the UPS that it cleans interferance and surges but I dont think it will correct sine waves. I did a stess test on this thing tonight. I ran a 1500w heater for 1HR and it did fine.

You know… I just threw away a UPS similar to what youre showing. I have two more that are going bad that I may have to consider changing over. Question, could a person take a modified sign wave as input into this, then the output would all be pure sign? Just a thought?
September 24th, 2010 at 5:25 am
OK, I finally get it, thanks. I now realize your stereo is powered by the wall inverters and is not directly connected to the UPS. So your UPS supplies 120V AC to the wall inverters and the wall inverters pass that on to the stereo. When the 48V battery bank fails, the wall inverters make 120V AC from your 12V battery bank.
My inverter must be cheap because it doesn’t have a transfer switch in it.

Hey Mark
I will try to do a video on fusing and maybe go into how my system is wired and point out all the safty features.
September 24th, 2010 at 6:32 am
Another great video Kevin thanks. Have you posted about fuses before? I have the 300Watt inverter like yours but had to move up to the 600Watt due to my panel putting out to many volts. My tests have worked great now. I was thinking I needed to put in a fuses for safety. Can you post a video on how you have yours system set up. Maybe I can use a rest switch. Very new to this game so I’m looking for lots of input from those who have had success.
Thanks again!!
Cheers Mark

Hey FIELD
When the inverters on the wall are pluged into A power source the transfer switches inside pass the power strait through. When the power is removed they switch to battery.
I guess the answer to your qustion is the UPS will feed through the inverter till its batterys are drained and will shut down. Then the inverter on the wall will see no power coming in and switch to the main battery bank.
I hope that was what you were looking for.
