Generator help

gmax137

biferi – where do you live? Is it cold there? Here where I am it is cold, so the main reasons to have a generator for power outages are to keep the furnace running (controls and circulating pump or fan) and to run the refrigerator (so the meat doesn’t spoil). Compared to these, a DVD player and a TV are small loads. So, just keep your priorities in the right order! Also, if you have a long power outage, there is no sense in watching TV because they will just say over and over, “the power is still out and it is cold.” You knew that already! If you want to watch DVDs maybe get a portable player and some batteries for it, that will be cheaper than the big battery and inverter discussed above.

Soory I live in the USA but this is more of a Fun Project for me.
You see we Lose Power even if it Rains a little.

So I just thought it would be nice to have a GEN for watching T.V. and to plug the Lamp in.

So when you Buy an Inverter it will Output 120 VAC but what will the AMPs be?

What I mean is if I have a 12 Volt 48 Amp Hour Batter the Inverter will output 120 Volts but will it just pass the Current through as is?

So I still will get 48 Amp for 1 Hour?

Most auto parts stores and walmart will have deep cycle batteries.

Thanks for getting back to me.

This is my Project.
I will have a 12 vdc 48 Amp Hour Barttery and a 12 vdc Motter all in Parallel.

Now the Battery will be connected to the Inverter to give me 120 VAC and when the Battery goes down I can Hand Turn the Motter Shaft to Re Charge the Battery.

Ok this is what I would like to try just for fun.

Take a 12 Volt 48 Amp Deep Cycle Car Battery and hoock it up to an Inverter.
Then I can run my TV Lamp and so on off it just little things.

Then hoock up a 12 Volt Moter with the Shaft sticking out and connect it to a handel. And then when the Battery goes down just Crank the Handel to turn the Motter Shaft and this will re chartge the Battery.

Will this work?

Sure, but you'd have to have to crank literally all day to recharge it. Even if you hooked it up to a bike so you could use your legs (much stronger than your arms) it would take several hours.

Also, no one corrected you before, but you seemed to think that you could provide 48 Amps for 1 hour at 120 V. The 48 amp-hours is at 12 volts. If you multiply the voltage by 10, the amp-hours are cut by a factor of 10 (4.8 amp-hours).

Thank you for all the infor.

Can I make a small GEN. just to run my Lamp and TV and DVD Player?

russ_watters

Sure, depending on what you use to power the generator.
