How long will a 36 V 10 amp hour 360 W hour battery when fully charged run a 1000 W LED lamp. Can I use a modified alternator to charge the battery?
If I use a bike to turn the alternator...would thIn theory around 20 minutes. In practise a lot less since, depending on the battery chemistry, you'll be limited on the rate of discharge and/or the depth of discharge.
An alternator, suitably driven, could easily supply the WHOLE supply current (28A) - many car alternators are rated at 65A so it would run the LED and charge the battery at the same time. Of course you'll need at least a 2hp motor to drive the alternator.

thanks for the heads up. Should I use more like lamps with my bike and alt an batt?1000W LED lamp? I hope you have eye protection.

This, after asking about attaching an alternator to a BIKE!? If you mean a human-powered pedal bike, you need to realize that a well-conditioned athlete will have trouble maintaining a power output of 50 watts for any significant length of time on a bicycle. A kilowatt is simply not possible. OTOH, if you mean a motorbike or motorcycle, good luck retrofitting an alternator to one of those. Most already have an alternator fitted to provide power for the lights, ignition system, and to keep the battery charged. It is unlikely that you will find a one kilowatt alternator that can be shoe-horned into ANY motorcycle. And most "bikes" today are fitted with 12 V NOT 36 V batteries.Or can you give me instruction as to what I should do?
Well that's discouraging... What if I pedal on 20 alternators for one hour? Lol. I kid.Good luck with that. About 20 hours of pedaling will get you abouy 1 hour of light.

No, you would not be able to push the pedals at all.Well that's discouraging... What if I pedal on 20 alternators for one hour? Lol. I kid.
Lol! That's awesome...but I don't grow pot. I build aquaculture systems...or isolated ecosystems for production of fish and vegetables in a balanced state of symbiosis. I intend to start a business building customized or "pretty ones" for schools and nursing homes.No, you would not be able to push the pedals at all.
What you need is 20 guys pedaling bicycle alternators, and they can keep your 1000W LEDs going as long as they pedal. You can pay them with the profits from your cannabis sales.

thanks for the info... I do six hours year round. About my pump if I run it in 20 minutes cycles and it takes 120 V 60 Hz and 0.45A ... How much more wattage will I need from solar panels?20 alternators would mean 20x the effort. The human body can produce about 100W (the output from ONE very good quality bike alternator) with a very vigorous pedalling exercise. If you can keep that up for an hour you'd be in the Tour de France team.
Even solar panels wouldn't be satisfactory. 1000W of solar panel energy would be about one third the size of a decent roof mounted installation..... imagine the cost!
There is no cheaper/easier alternative than connecting the LED straight to the mains (via its power supply of course) - the 'green' idea that you can get around this is misleading nonsense.
At best you could use solar panels to charge a battery and use the battery for the night time period but, as stated, the maximum time you can run it for is dependent on how much charge you can get into the batteries before they are used.
If you want to use the LED for 6 hours, you need 1000W from your solar cells (plus some extra to cover system losses) for six hours too. Assuming you actually GET 6 hours of sunlight......

No the pump is necessary to lift watter in an aquaponic system... I may not need that much wattage from my light... Where where I live and will be working sunlight is usually pretty good but right here at my house there's a lot of shade. But I definitely have to have a pump running.so you have given up on the 1000W LED now and going to try a pump instead ?
Get six6 hours of what ?

I apologize that was supposed to say six hours of sunlight daily year-round at least... As I said I may not need that much light but I still need to pump water 9 feet high.6 hours of what ?
