Amazing. You just posted the answer to a DIY question I was working on. How to run a 12 volt roof top vent fan from a more than 12 volt solar panel. Don't need a battery since fan only needs to run when the sun is out. Perfect solution!

I love these simple cheap videos Will. They can help a lot of people.

Again You Have Outdone Yourself! I Can See An Application To Charge Any Item That Is Run By An Internal Battery Supply! And That Hat Dude Is Gangsta!

Will, may I suggest an interesting experiment: using ice as a battery. For your refrigeration (I notice you have replaced your fridge 4 times!) you can get a small super insulated freezer, and use that ice in super insulated fridge of your own build. A very substantial properly insulated fridge will stay at fridge temperature for 10 full days with only about 7 pounds of ice. Ice as it melts, releases 144 BTU per pound! (or 42 Wh per pound, ) about the energy density of a decent battery. Check out a number of youtube videos testing coolers with ice. Some retain that ice for 10 days at temperatures of 85 F out in the sun.

To see a schematic of this micro system, and what converters I recommend, check out this page:

Push this concept Will- so many people will love this. Nice yo see you in the sunshine - did you film this back in July?

[Electronzap]

buck/boost converters are really awesome :) I have smaller, low power ones that you can adjust the output voltage.

[danieltimisan]

even better than those convertors you can get a iCharger x6 that has an adjustable voltage output for whatever need you have but it is a little more expensive

[johnperry]

This is absolutely insane, I love it. If I had not seen this video I would not know that you could do this. Thank you for this video. I can't wait to do this.

[stevencartlidge]

Great little project. Had fun building one myself. Thanks for the sharing .

[travelingtimothy]

Very interesting and a simple way to set things up. Got to have the sunshine though.

[ZenInnovations]

Interesting product. But I would still put a small Battery just to work as giant capacitor. Makes output far more reliable and will also absorb excess solar energy.

[opera]

This could be a bad idea. If Will owned an oscilloscope, he would know this. Many inverters have stickers that say not to use them with AC power Inverters. The reason is internally the capacitors are not large enough to handle the pulsing current of a sine or MSW inverter. I tested one with a12V panel and the input voltage had 7V of ripple. This will damage the capacitor over time and most of these units are potted. Because the capacitor is small the energy in the current valley can not be stored and your system will produce less total power for a shorter daily time. 15, 000 to 20, 000 uf must be added to the input to fix this. Then things will run a lot better with pulsed loads. I do a lot of direct power without batteries and these devices are great if used properly.

Another idea is to use a DC water heater element, and thus store your energy as hot water. The ultimate cheap battery!

[mikedesverknopf]

This actually might help me save a butt load of money. Thanks man

[mmyeseo]

Thanks for the experience. I am now using it and I am reassured

[drymoonproperties]

I like another viewer love these videos they are simple and to the point. These videos will definitely help many people including me until I have my complete system built.

[tssproduction]

Thanks for the insight.. water well time. I have a couple laying around for my golf carts. Really enjoy your videos.

[DaveSquibbSr]

I use a 12 to 24 volt step up like that to charge my power stations from a 200 ah 12 Volt battery, great little devises.

Need constant sun, Lives in the UK, moving on :D
