Very nice setup ! But i have 2 questions , what kind of things are u plugin into it ? and if u charge the batteries during the day. How long will your setup last at night if u had a tv going, along with a few other appliences ? im very interested in your solar setup .

@jmnic63 Thanks for your comments and questions. This is an old video and I've expanded quite a bit. However, I've answered a similar question or comment in the comments section of this video, in response to @OldTroll11 below. The response shows you an example of how to calculate runtimes of various items when using battery power. My latest videos show my expanded system. Take Care.

great system! where did you get your supplies?? i want to duplicate it! thanks edv

@pennvloger Panels, wire, and charge controller from wholesalesolar(dot)com, AGM batteries from different sources. You can get good inverters from theinverterstore(dot)com. For cheaper panels check out sunelec(dot)com, ecodirect(dot)com may also has some good deals for you. You can battery cables from any autoparts store. 10 AWG wire can be obtained from hardware stores. Battery monitors from Amazon or eBay.

need 4more battarys

@jcb570 Actually, this is an older video I now have 12 batteries.

Good video...

Commercial Solar Panels are too Expensive

The only option you have is to Build Your own Solar Panels

This might sound like a stupid question but could you run a welder with this?

[rhandsom]

@mikestan167 When considering how to wire your panels, you must consider panel voltage, wire gauge, distance from the CC and the type of CC being used. My 12v panels use 10AWG wire that is more than 30' away from the CC, which gives more than a 5% voltage drop, making parallel wiring impractical. A series wiring with an MPPT CC works much better in this case by it using an internal DC to DC converter to use excess voltage to increase amps giving the same benefit as parallel wiring.

[mikestan167]

Why wouldn't you just wire the solar cells in series to obtain 12Vdc. And then connect the 12Vdc cells in parallel to get more current output to charge your batteries? Seems like a waste to go from 36Vdc and step down (power loss) to 12Vdc.

@gregoryscottsr also you would need a VERY big inverter to run a welder now you can take about 3 battery and make it where you get about 30+ volts and use that to weld with in place
