Need advice on "reasonably priced" 24V inverter

[SunEagle]

If the grid goes down for more than a few days, it's going to Mayhem, no one is going to be your friend - not even your friends. A few weeks ago, Stores in N. Central FL had a momentary black out and shoppers went wild and started looting. It will not take much.

So no one will thank you for being a whack job now - and trust me, I'm right there with you for the same reasons. But, no, if you have food and power, they will come after you. So You had better be loading up on guns and ammo too and be prepared to shoot and keep shooting. A world without the grid is a world most of us would probably not want to live in. (or at least would not be prepared to live in very long)

People for some reason are very edgy and you are correct it will not take much to light the fuse on the powder keg.

IMO if there is an extended grid outage having solar or emergency power may "draw the pests to the light". You will need a big bug zapper to keep them away.

Instead of batteries, how about freezing a lot of those (state change) freezer packs when the
sun is shining? Then blow air over them after sunset. Bruce Roe

I'm sure that will work, but then you can't set it and forget it. Plus I'm sure that will add to the humidity. All I see is never ending gloom and doom all over YouTube. If one day the power grid goes down for an extended period of time, all of the people who think we are whack jobs for being interested in this solar stuff will all of a sudden be best friends with us once they realize we are the only ones in the neighborhood with power.

After this A/C project, I would next like to see how I can easily charge my electric car.

The company said I need at least four 12V 150 Ah batteries wired in series. That has to keep the A/C running for nearly 5 hours. I guess I could go with 200 Ah ones. Those would be huge in my master bedroom to run the A/C.

[Justin B.]

When in parallel voltage stays the same and current goes up. When in series voltage goes up and current stays the same...

[ButchDeal]

I need 600 Ah worth of batteries for it, all wired in series for 48V. They said to order four 150 Ah batteries for it.

I suspect they want you to get a 150Ah 48V battery bank not a 600Ah 48V battery bank.
four 150Ah batteries in series makes a 150Ah 48V battery.

[RenewablesRock]

Would that be 4, 48 volt, 150 ah batteries?? no such creature. If you were to find one it would weigh 400+ lbs. If you were to use 150 ah. 12 volt batteries then you would need 16 of them to achieve a 600 ah. @ 48 volt battery.

No, four 12V batteries that I wire in series to make 48 volts. That's what it requires.

Here's the A/C unit. This price is for the hybrid that requires 220V or solar panels. The one I'm ordering is $509 and it's the off the grid version:

Plus I have to order their 48 volt inverter for $80. Plus shipping and freight forwarding. Then I still need the batteries which I can get from the same people or there are many others on there selling 150 Ah batteries as well.

I finally found an A/C that will run on solar. For a little over $700 for the unit and 48V charge controller than it needs to run. Plus I should be able to use 4 of my solar panels to make it operate. And then I need 600 Ah worth of batteries for it, all wired in series for 48V. They said to order four 150 Ah batteries for it.

I just sat here writing a super long message and now it's gone. This is becoming too cost prohibitive of a project. I cannot spend more than I have in the bank. I only have a budget of what's available in the bank, which is really small right now.

Instead of spending thousands on the batteries, it would be cheaper to buy the HotSpotEnergy ductless unit. How can I find competitors for that? I saw a similar unit for $635 on Amazon, but it wasn't able to run 100% on solar.

SamClub also has 215A GC2 for $84 (39 cent per Amp) ; I think this is better deal that 230A for $124 (54 cent per Amp)

Just my 2 cents

Wow! That looks amazing! But isn't that flooded? So I won't be able to keep these in the closet of my extra bedroom. That's what I am trying to accomplish.

The 230 Ah one is $124 near me.

So for $500, I could have 920 Ah of power. How many cycles can you get for that? These sound like a good deal if I don't have to worry about hydrogen filling the room.

I found that Sam's Club has Duracell 6v golf cart batteries for $124 and change. Here are the specs:[/LIST]

That is horrible advice. If you need 800 AH, buy 800 AH batteries. Never ever parallel batteries.

As for Trojans, you get what you pay for. Any of the FLA models would work. You need to come to terms with anything you take off-grid is going to cost you 5 to 10 times more than buying power from the POCO, and also makes you a heavy heavy polluter. So wrap your head around going off grid is going top be very expensive, lot of work, and nasty nasty for the environment.

The problem is I can't spend more money than I have in the bank, so a lot of this is 100% impossible. The stuff I have now was all relatively inexpensive. I am putting my batteries in parallel now because my inverters are 12V. The inverters I want are out of my price range.

The Renogy I am looking at is also 12V:

https://www.renogy.com/renogy-2000w-12v-off-grid-pure-sine-wave-battery-inverter-w-cables/

One of my goals was to be able to run AC during a power outage. It looks like I should dump the idea of buying thousands of dollars worth of batteries, that will all have to be replaced in the not too distant future and buy this:

http://www.hotspotenergy.com/solar-air-conditioner/

No grid connection needed.

Where can I find competitors to these people? Isn't there a ton of people also making similar A/C units?

This is the unit I was originally looking at buying:

http://www.climax-air.com/documents/Climax-VS12-SpecSheet.pdf

But that unit would require thousands of dollar in batteries, plus the expensive inverter. Not to mention 3/0 gauge cable, most likely to be able to pull out all of those amps.

From what I can tell, this entire industry is in desperate need of competitors to flood the market to bring down prices on all of this stuff.

Going off grid should be super cheap compared to paying the power companies. What can we do to make all of this hardware much more affordable?

Everybody I talk to in person tells me the same thing, "There's no ROI on what you're doing."

I just wish I could find a $600 version of that HotspotEnergy A/C above and put like 3 or 4 of those suckers in my house. Then 12 solar panels would save me a fortune in electric.
