What do I look for in a solar powered battery charger for a 12 volt RV battery? Size, Amp? or watts?

A motor is an electrical device that turns electrical energy into mechanical energy. I really don't think that is what you're after. You want to turn mechanical into electrical, right? Okay, in old cars, before they had alternators, they had generators. Snag one of these at a junk yard. It will charge a 12 volt DC battery. I have never done this, I am just theorizing as I type. Anywho, campers use 12 volt DC lighting as a back up. Heck even the fridges run on 12v, propane, NG, or AC. In theory, fabricate blades to this generator, with a voltage regulator and there you go. Actually, here is what I do. I used camping lighting that burns clean fuel and flashlights, but if you simply had an inverter, you could actually run a few things via you car. Another suggestion, a more serious one. Look at the way they make campers so self sufficient. 2 lighting systems, where one runs on AC and the other DC of 12 volt batteries. Not a bad idea for your house? They have there own battery charger, which you could put in your house, that keeps these batteries full whenever you are plugged into AC. Add a 12 volt light system to your storm center, add a camping stove with a small portable tank, vent the area. This stove could cook and serve as a source of heat. Get the fridge that runs on anything, what else do you need? Oh yeah, plans for a wind generator. Dragonfly Wind Generator. That's what you are in need of. Perfect for residential.

If batteryplus.com doesn't work, try ebay.  You'd be surprised what you can find there.  BEST OF LUCK!

Dunno for sure but dont be too hasty on blaming the pute. Go to radioshack and invest in a cheap volt meter, put it on dc volts and measure the voltage at the output of the charger....the charger will tell you what it should be for voltage....sounds more like the charger took a dump to me....it may also be the battery.

odds are, that you would be beter off buying a manufactued device, dc to ac inverters are very complicated and have many different circuits. not only that, but for you to make something that can invert that much power would need an extreme amount of skill to to get the proper components. I would recomend geting a manufactured model from marine purposes perhaps. Some companies should offer custom built electronics.

‘watt’ is the unit of power. It means joule per second.\n\n12 watt means it can impart 12 joule per second.\n\nTherefore, the answer to your question is it will impart 12 watt to the battery.\n\nIn one hour it will impart  12x60x60 joule; 12 watt-hour (energy-not power).\n\nIn electrical unit one watt = 1 Volt-Ampere. \n\nIf the battery of 12 V is charged for an hour using 12 watt power, then it can give a current of one ampere for an hour. If the current is reduced to 0.5 ampere then it will work for 2hours. If the current is reduced to o.1 ampere, it will work for 12 hours.

It is not watt per hour but watt hour that you're trying to find.\n\nBut the answer is yes, you'll use 15 kWh.\n\nStill, I'd be careful about using a lot of them, the cops have thermal imagers which can detect them from helicopters so if you're doing anything illegal with them...

If you mean a 12 volt mobile radio like a ham rig, you should need a 12 volt DC power supply.  The antenna will need a ground plane.

Take a look at your electric bill.  It will tell you what your average daily electrical consumption is.  You will need some form of electrical production that meets that amount every day.\n\nMost home battery systems use 12 volt batteries connected in series to obtain a high voltage.  Then the batteries are connected to an inverter to produce 120 volts AC.  You can buy inverters that are rated for about 5 kW.  If you have a pair of those, one on each leg of your electrical connection (L1 & L2) it is good for 10 kW of power which should be enough for a most homes.  The reason for being able to handle high power is that sometimes the refrigerator, A/C, stove and TV may be on at the same time and draw a lot of power even if it is for a short time.\n\nThe size of your battery bank will depend on your generating system.  If you can generate continuously, the battery capacity can be reasonably small.  If you are relying on solar and wind energy and have to account for a few days of overcast skies and no wind, the batteries have to be quite large.  Sizing the batteries takes a bit of research.

you'll need an adapter...different types of electricity

You need to hook enough solar panels in series to give a voltage slightly higher than that delivered by the car batteries.   I'll assume that they're 12 volt batteries.   Connect the panels in series until the output is about 12.5 volts.   Connect the ends to the terminals of your battery, checking that the polarity is correct.   When the batteries are partly charged, they'll easily deliver 120 VA for short periods, but unless you've got a very large array of solar panels, you won't get anything like this amount of power from the panels alone when the batteries are flat.   Car batteries are designed to deliver well over 1000VA to the starter motor.   I live in the S of NZ.   Not far from here there's a hut on a sheep station with a system like this that delivers power to a 12 volt lighting system.We probably get much less sunshine than you do in your climate, but last I heard, the system works fine.

1.125 KW or 1125 Watt

make sure you have them connect to 12 v, not 5 v, they should run at about 2500

That would depend on the voltage. Current = Watts / Volts\nA couple of examples:\n110V - 90.9 Amps\n220V - 45.45 Amps\n240V - 41.67 Amps\n440V - 22.7 Amps\n10,000V - 1 Amp

A self sufficient solar driven electric car. It will never need recharging. The source of power will come from the solar paint, braking system, tires and aerodynamic wind turbines under the car.\n\nAnd a optional magnetic drive engine!
