How to build a 1000W of power output

[MarineLiner]

Sorry, we don't get any addition info of how long the 1000w will be used.
i think if only for radio and little light, the battery will be not too many.
But if 1000w for 12 hours will need a lot of batteries.

Thank you very much.
i make a new topic:

as we won't make ourself out of topic here.

Something similar to the following (from another site):

(head(in ft) X GPM) / 10 = output in watts for a standard micro-hydro unit. So (10 (ft) X 100 GPM)/10= 100 watts. And with 1000 gallons this will last 10 minutes. 100 ft x 100 GPM = 1kVA which is about what an average US house needs. 100 GPM X 60 min X 24 hours = 144000 gallons per day.

or

In very rough numbers, a 1000-gallon tank 100 feet high could store about 3-4 kwh

Same thing can bee applied with a elevated water tank.
You pump water up in the tank, and release it later to generate electricity. Sound cool but really inefficient.

Plus the volume of water required per kW generated is rather large.

Actually it is quite old technology and used by hydro electric utility companies. During power generation using dams, you take the unused generating capacity to run pumps to pump water into a lake to later be released and generate power again.

Well battery efficiency is around 80 to 90%.
Pump back tanks are on the order of 25%.

- try and aliminate as much on battery dependacy is a good policy but I am not talking about a large just 2 of them how else will you store the power to use after dark? or are you just sujesting that he should not use the radio at night?

... would fall onto the size of battery pack you have set up, providing your solar panel can suply the correct amount energy to keep battery pack charged for night time use?

[BuzzBuds]

I guess sunking is saying is for how long do you need the 1kw for.
I also thinkI am new to all this too but that would fall onto the size of battery pack you have set up, providing your solar panel can suply the correct amount energy to keep battery pack charged for night time use?

[Sunking]

Well your question does not make much sense. If you need 1000 watts out from the panel, then you need at leat a 1000 watt solar panel.

I think you are mixing up power and energy.

Watts = Power at any given moment in time and is an instatanious measurement or expression.

Energy= is the amount of power over a given amount of time. In electricity it is expressed as Watt-Hours. Watt-Hours = Watts x Hours
