I heard that it is possible to use car batteries to power your What ever whatt you have.. I just wanted to see if anyone could help me figure it out as far as doing it or at least testing it out.... If i got it down it would be a sweet way to cut down on the electric bill. Someone let me know if it can be done or let me know that its not going to work.. So i can go tell my friend hes full of shiattt!!!!

Not sure but wouldn't suprise me.........My 52 inch DLP tv runs off a AAA battery

Sweet bro.. Yeah my PS3 is solar powerd so if i can just figure out how to get that dam 400W to burn off a goodyear battery! then I will be as cool as you. and your AAA battery DLP..

A car battery for a SUV or van for a 400w light will last 10 hours or so. You would need too many batteries and a way to charge them anyway, so you might as well just plug it in to your wall. haha

lol

i think you could like do the funniest grow ever and just get a big AstroVAN, setup your grow in the back and drive it around all the time to keep the battery charging (way way more expensive to burn gas to keep it charged than just plug it in at your house anyways)

Probably not possible but the thought seems pretty funny in my head

yeah, if i can run a thermo-nuclear generator off a couple potatoes and some wire, i dont see why not.

what a great idea. it actually could work, all jokes aside. I think im going to take that on as a project. ill just convert the engine to like some kinda hybrid biodiesel so i get stupid gas mileage and clean emissions

what if you had like 2 or three batterys and a few ebay solar panels to run the charger. Something like that

i haven't really noticed my electric bill going up very much with a 1000w - unless you are on an extremely tight budget doubt you'll notice much and save you the trouble of having to have multiple batteries charging all the time.

If you wanted to do this, you need: a) DC to AC power inverter capable of handling the power; b)a electrically strong enough connector to handle the current; c) wires of a gauge sufficient to handle the current (amps).

If you want to add a solar charger, make sure you have the potential for current to flow, otherwise you won't charge your battery. So, if you are going to charge an automobile battery_which is 13.3v, nominal you would need at least a charger capable of producing 14.4 volts. This would yield a 1.1v potential for current to flow. I would search for a solar charger capable of 'generative current' something like 17v and 1amp output. This would not yield a fast charge but it would certainly slow down the discharge process if hooked up to the battery at the same time the lights were connected_of course you'd need a small circuit to prevent problems.

An easier way would be. Go find a used 'UPS' Uninterruptible Power Supply from a computer shop that needs a battery. Replace the ac input with your solar and use your car battery instead of the small one inside the unit_remember to increase gauge of wire from battery to UPS. Then plug your cfl's right into the socket on back of power supply. You want a UPS and not an SPS. UPS always has the inverter running. SPS doesn't.
