Help Needed.
« on: July 06, 2019, 01:09:06 am »
Hi, Anyone feel free to answer your opinion or fact here. I want your Thoughts and comments Please.
Please Dont be shy, Im really interested in what your point of veiw may be here. Everyone has their on thoughts so Please feel free to share yours with me.

Here is My question.
By the way, I dont feel comfortable Posting in a open forum but atleast this one is registered memebers only. Also, I have noticed that IonizationX doesn't show up in google results for me the way it use to stevie. Im sorta thankful for that, but anyhow. Here it goes!

-----------------------------------------------------------------------------------------------
If you have an Window AC unit and it consumes 600 watts of electrical Power P. At 120 volts V, at 5 Amps I. Just a thought. Now on to the question.
------------------------------------------------------------------------------------------------

Question. If you have say 92 1.3volt rechargeable batteries in series, and the voltage was close to 120 volts. How long do you think the batteries would remain charged if producing 600 watts? I think each battery would produce 4 milliamps, I may be wrong.

How many amps do you think each battery would use? How long do you think they would remain in good health before voltage started droping?
Do you think you can divide the I Current draw as I just did say 40 Milliamps per battery? Or, does the current work some other way in this series configeration?

Please ALL COMMENTS Wanted!

Thanks!

What if I used 13 9 volt batteries and got 117 volts to produces 600 watts.
Wouldn't that be under 400 Milliamps per cell?

Stevie, whats your thoughts?

You'll have to use a lot more batteries than you're planning, to have an effective system.  In series, each battery's Milliamps will be in the normal range, just as you suppose.  However, the individual cells' voltage will start dropping almost immediately under load.  The result will be that you get your 600 Watts only for a brief period.  What you need to do is provide around 2 1/2 times the needed voltage, then run it through a regulator to output the 120.  This way you'll stay at 120 for a while, even as the cells go down.  Even then, you'll be lucky to run for a half hour, without parallel strings of batteries feeding the regulator.

So, the 9v cell will drop when consuming 300ish milliamps after how long? Haw many must be in parallel to solve a 8 hour runtime? Let's go with 9 colts here.

I think I would contract the manufacturer of the batteries and obtain the discharge specifications for the brand of battery used    (something like car batteries rating  ampere hours)

perhaps get so idea of battery sizing from Tesla 3  electric vehicles??

A typical 9 volt battery is between 300mah and 500mah. So since this isn't actually field work here but "thoery only", let's just assume the battery is anywhere between 300 to 500 mAh, doesn't matter because it is the ideal we are after here And not firm solid legit perfectly crunched numbers. Let's crunch what we have and get a rough estimate.

With that being said. What would be your best bet using 13 batteries 9v. ? 5 seconds, 5 mins? 15 mins? And would it be benifittable to add 13 more in parallel. Let's assume we used 52, so that's 4 9v in parallel.

how exactly is a solar panels built anyhow?
I have 5 panels, each is 37.5 volts and 8.5 amps.

If I connect 2 of the panels in parallel I get double the current production and the voltage remains the same.
But, If I connect 2 of my panels in series, the current production remains the same but the voltage doubles.

If I were to calculate the 600 watts directly from the utility pole, I would say I use 30 Milliamps at 20,000 volts, then onto the 240 pole transformer that consumes  2.5 amps, but my Window unit is 120 volts so I must have 5 amps.

I thought about powering the unit with a 12v  battery at one time since everyone says thats the logical way to do it, but then I decided that 50 amps from that battery at such low voltage was not as appealing as the 120v DC using a H Bridge at 5 amps. But then I realized that If I could just somehow use 240 volts at 2.5 amps I would be more than willing to donate a amp or 2 for the heat loss of stepping it back down to 120, since the unit does operate on 120 volts.


I installed a new unit the other day and the rotor locked up, the locked roter amps was 108 amps at 240 volts. I realized that a locked moter was consuming over 25,920 watts!!! But I dont think anyone hardly noticed since I was only using 1296 Milliamps from the 20kvolt power line wire!  :)

I still dont fully understand how my solar panel is built, Is it like one very long strip that produces 37 volts? and also, how you reckon it produces a whopping 9 amps of current at that 37 volts?

Anyone gave any thoughts to those 52 batteries in the question I ask above yet? Again, Your opinions are welcome, and No answer here has to be perfect. Get the Ideal in your head so I can be cleared up on this, then I will move on to the next step.

Thats a circuit I think is junk, But the Ideal is Legit, it has way to much computerized junk on it.

Which battery would you buy?
Think on it a while... And I understand most devices will not operate properly on lower voltages.
