My customized xantrex 1500 portable power supply.AVI

[tntinucciable]

Hello. I want to build a powerpack with extra batteries. Is there a website you got the DIY info or did you just figure it out? Can you send me an email maybe or walk me through. Thanks tntinucci@gmail.com

@vention4wh Thanks, I didn't realize that I could backfeed a standard 120v outlet but it makes sense.

[hekg]

Just bought this unit and I like it alot. Is it possible to hook this up somehow to my home's transfer switch 240v connector? Can I use a Y-adapter to use the two 120v outlets to plug into the 240v on my switch?

Something like the opposite of this Y-adapter? Conntek-YL1430520

@hekg

I imagine it's possible but you could probably do the same thing by just getting a double male extension cord and plugging it into your wall (after you've pulled the main breaker of course). Be careful you don't have a high wattage device in the circuit though or your inverter will shutdown until you shut it off.

If you have an actual house you could even start buying deep cycle batteries and slowly build yourself a serious backup power system. I want mine mobile though.

I HAVE THE SAME THING BUT WAY SMALLER

[MrGideonsPress]

Great Job, but by adding the extra batteries what is the highest wattage appliance you can run with your extra batteries. The standard unit is rated for up to 1350 w. How much more can you get with the extra batteries. Can you run an 1800 watt hairdryer for example? Or is it still 1350w maximum just for a longer time?

[vention4wh]

@MrGideonsPress

Nope, adding more power storage doesn't increase the watts that the inverter can kick out. As you suspected, it will just run for a longer time.

i have a few questions what are the sizes on the batterys ah rating an how much they thanks very much

[sirmasterpimp]

Nice, I have quite a few batteries myself (xantrex and others). What is your total amp hours with the additional batteries ? I know the xantrex 1500 has around 60 amp hours stock.

Nice, is that a lcd or led I'm looking to save a little buy getting an led, I have an lcd it uses more then my regular tube TV the tube is 46inc and the lcd is 2 inches bigger ,,and the power consumption is huge on the lcd the brand is Polaroid, I was kind of furious when I found that out,

[jihadacadien]

that looks like something you see in those survival movies LOL!!! still is pretty great!

[Zarthalad]

Fantastic thank you so much for showing this, it'll be a huge help!

Sweet !!

@Vention4wh:

This is an ingenious set up. Congratulations on this unit. However, you know my pessimistic nature. In the event of a SUPER solar maximum, you will need to store this unit and your solar panels in a faraday cage.

[vention4wh]

Ya it has a chance of being destroyed by an EMP type event but I keep the solar panels shorted, which makes them a lot more resistant to EMP. Still those are comfort Items. If an EMP hits I'll just go back to grinding my wheat with the hand crank grinder.

Its a very nice system, power without noise is a great and useful thing.

[YounaTuber]

Vention4wh- This is an amazing, clear explanation and I can't tell you how much I appreciate it. John and I just watched this together. We were talking and pointing at this or that as you spoke, and I have to say- you've made this so easy to understand and follow. Our conversation the other day really helped as well! We're looking forward to getting this wind system up and running, and as of right now, we're just waiting on the guy to get the pipe back to us when he's finished welding.

Awesome! I can't wait to see it on video!

Think I'd go WAY up on the wire size (Like maybe 4 ga. or even 2), to prevent any line loss. No sense wasting juice.

[vention4wh]

@GoatHollow

The line loss for such a short piece of wire is very low. I have an excel sheet that I keep all kinds of electrical and wiring data. I could probably get it to you if you want to check it out.

Anyway 14 gauge wire has 2.525 ohms of resistance per 1000 feet, so the only thing I really need to worry about is how much amperage it can carry without the wire getting hot. Heat is of course the enemy of wiring. 14 gauge wire's spec for chassis wiring is 32 amps or 384 watts.

[GoatHollow]

@vention4wh , I don't get quite that technical about it, but the major idea for me.. is that heat means lost energy. If 14 gauge wiring gets hot to the touch, then the biggest size wire possible, will create the least heat, and therefore loss . I tend to think in terms of overkill. I do know that "Code" specs out 2 gauge wiring on a household solar system, even though you are right in your statement that the distance is small, so are the "Panel" distances on solar.

[vention4wh]

@GoatHollow

Hmm, Guess you're right. I do need to upsize. I want at least a 700 watt (58 amp) capibility so that would require either two 14 gauge wires in parallel or a 9 gauge wire.

Of course going by that awesome system you built, you might know more about this stuff than I do, so correct me if I'm missing something here. Thanks!
