    Much appreciate your videos – they are the best for learning solar!

  2. acela30th on May 7, 2021 at 12:56 am

    I have been trying to figure this very thing out and I am glad I accidentally discovered this. Very good communicator. I have a 100W Coleman kit from Costco and a battery from Costco. I think the charge controller is 8 amps and is flimsy and I will buy based on your links. Thanks.

  3. Airica S. Harms-Colby on May 7, 2021 at 12:59 am

    Your videos ROCK! I feel a lot more confident in setting up my own system, thank you! 😎🤩

  4. John Lowery on May 7, 2021 at 1:06 am

    Would I be able to use 550w to soler panels 275 w a peace would it work for this system

  5. Roger Smith on May 7, 2021 at 1:07 am

    I’ll have most of my parts next week. Haven’t decided on a battery yet. I’m on SSI, so got to be on budget. I’ll review this page again next week.

  6. cc on May 7, 2021 at 1:10 am

    Any advice on retrofitting my travel trailer? I already have a fuse and breaker panel. And it has an integrated charge controller/converter with no lithium setting. I’d love to see a video on how to tie in and make that work. Thanks for the videos!

  7. Bret Sehorn on May 7, 2021 at 1:10 am

    You make the best, easiest to understand videos ever. But, growing up on a farm we used pliers for everything, and we never called them wrenches……

  8. daffie halley on May 7, 2021 at 1:10 am

    Will. I have opertunity to get
    2 panels but they are different wattage. one is 400w the other is 370w . Will they play together?

  9. grimm jow on May 7, 2021 at 1:11 am

    Any thoughts on using connectivity jel or putty to help loss of power transfer?

  10. Fu Updaass on May 7, 2021 at 1:11 am

    Still recommendthis kit?

  11. Bitey Dog on May 7, 2021 at 1:12 am

    Very helpful, thank you!

  12. Boatdog van Traveller on May 7, 2021 at 1:13 am

    A good idea would be to install a fuse or dc breaker on the positive cable from the battery to solar to protect the cable and regulator. Another good idea would be an isolator to kill the voltage from the cables going to the battery incase you need to remove the battery.

  13. Rich Henry on May 7, 2021 at 1:13 am

    Dont capitalize on us poor pls dnt even have much food far less for money we are tired pls

  14. jeff stowe on May 7, 2021 at 1:13 am

    Thank you sir for this informative relevant video.

  15. Jothimurugan P on May 7, 2021 at 1:13 am

    Well explained in simple terms, enabling easy understanding for we the non technicals.

    Could you please provide your email id.

    Thanks and keep updating more.

  16. Ted Cantrell on May 7, 2021 at 1:15 am

  19. Bella Seawitch on May 7, 2021 at 1:17 am

    Thanks for making such a clear video. I feel like I could get started with the information you gave.

  20. Rohn W on May 7, 2021 at 1:17 am

    Thank you for making this easy-to-understand video! I referred to it as I set up my simple system for my van. The instructions that came with the kit were very unclear and incomplete; you gave me the confidence to turn it on without fear of ruining the controller or starting a fire. You have an awesome teaching style. Thank you!

  21. Michael Sheehan on May 7, 2021 at 1:18 am

    You are an inspiration… Thanks!

  22. Dane Mart on May 7, 2021 at 1:20 am

    Great job, Will! You are a great teacher; detailed, informative! When I got started researching going solar, I figured I was in over my head. This video simplifies it, so that a beginner or "Average Joe" could do it. You provide those baby steps. So many cram too much info into too little of a video. Plus I can have the confidence in the products since you have tested/sourced good products and materials. Thanks.

  23. Jervy's Pizza on May 7, 2021 at 1:21 am

    Your explanation is awesome! Its pretty clear and I love it…

  24. Milton Tyotam KWAIPO on May 7, 2021 at 1:22 am

    I’m in Papua New Guinea and am very interested to buy this kit, please send me the link so I can contact the supplier of this kit – its really good.

  25. Putra Adriansyah on May 7, 2021 at 1:23 am

    What can i really do with 100w solar panel?

  26. Richard Blodgett on May 7, 2021 at 1:23 am

    How good is LiFePO4 Battery 100Ah 12V 1280Wh Deep Cycle Lithium Iron Phosphate Battery?

    I have learned so much from you. Thank you

  28. Phaedra White on May 7, 2021 at 1:25 am

    omg after all the videos i have been researching to use solar for my off grid cabin your videos are the best you are a phenomenal instructor thanks and i will be definitely using you for my go to as I progress my system

  29. Wanda Pratt on May 7, 2021 at 1:26 am

    You have taught me so much. Thank you. Your a Great Teacher 👍

  30. Shaun Tatham on May 7, 2021 at 1:26 am

    Hmmm seems really nice, cheap and straightforward unless your on the road and have a frigde full of beer and live with a tart with a hairdryer and straightinig irons??🤣🤣

  31. Jonas on May 7, 2021 at 1:30 am

    WOW! Solar made easy.

  32. Who wants to leave a bogus review Reviews on May 7, 2021 at 1:31 am

    Can I run a reg refrigerator off this solar set ? I need to use a ac too ?

  33. Ki Lee on May 7, 2021 at 1:33 am

    i think you forgot safety with wearing gloves when touching the battery. then grounding the panel.

  34. Paul Ortiz on May 7, 2021 at 1:39 am

    Can your solar panels charge more than one system, at a time? Or consecutively?

    With one set of panels I was thinking, just for example, I would have 1 set of batteries for, perhaps, 12v lights. And another system for a 110v ac fridge— only!!! (The fridge being important I don’t want to ever have a problem with its power supply, so a separate system with plenty of dedicated battery so it never gets interrupted, defrosted, etc!!!
    So, can one set of panels be used to power two different battery banks? If so, how would that be accomplished?

    And is it possible to always supply the fridge system first? For it to have precedence over charging anything else? To make sure the fridge batteries are as full as possible before other systems are resupplied. If so, how or what is used to accomplish this task?

    Thanks a bunch, times a thousand!

  35. Michael Lee on May 7, 2021 at 1:39 am

    I just finished installing the 200W Renogy starter kit, with this video playing as I did so, which made it simple and relatively easy. My work shed is now solar powered. Thanks!

  36. Mark Taylor on May 7, 2021 at 1:40 am

    Thank you Will, for the basic explanation of a Solar system. It is most excellent that you explained the connections and which to connect before the others. It makes sense that connecting the Solar panel to the Controller before the battery is connected will damage the controller.

  37. grimm jow on May 7, 2021 at 1:42 am

    Im doing an ultimate Portable Solar battery build for my suv that I live in the goal is for 32" tv , ps5 , fan or mini ac and possibly a small yeti fridge just for drinks and water and sandwich meats

  38. Eoin on May 7, 2021 at 1:43 am

    Hi Will I’m in Wicklow Ireland and I watched many of your videos and I bought your book from Amazon. I’ve built a 400w 12v system and went on to build 2 more for family and friends. I also just built my first 24v system. Thank you for all the videos and expertise.

  39. Rad Ostin on May 7, 2021 at 1:45 am

    Hi man. Thanks for the video. It is very well explained. I just have a question. Do we need earthing for this simple system, please?

  40. Shawn Rutters on May 7, 2021 at 1:46 am

    Like liked and subscribed because I saw a princess auto socket wrench my Canadian friend.

  41. Larry Fine on May 7, 2021 at 1:46 am

    It sparks because you should hook positive first. Then hook negative

  42. Luis Montoya on May 7, 2021 at 1:47 am

    Thank you, you are very knowledgeable.

  43. Ben Par on May 7, 2021 at 1:47 am

    Great video.
    But I would have connected the +’ve 1st.
    That way it doesn’t spark

  44. Jeffrey Hill on May 7, 2021 at 1:48 am

    Anyone out there want to weigh-in on my question here? I have been a commercial/industrial electrician since 1977. Four years in the Navy before that, along with their excellent in-classroom electrical schools.

    My question is this – I am building a small system out here in the California desert using two used solar panels and a Renogy 30A Rover charge controller. We work on a lot of yachts in Long Beach as well as electric Duffy boats. Therefore, we come across a lot of used 6-volt batteries. I want to pair up the batteries and only use the two best-matched ones at a time for playing with the solar system.

    It may turn out that these panels aren’t much good. I have already put my meter on the output terminals and find 20-some volts, so my research says they are 12 volt panels. I also counted the cells on the panel to confirm voltage.

    My first system will be DC only, no inverter. We work on a lot of boats, from tiny, up to the 100-foot Italian yacht we spent a lot of time on. Therefore, I am planning some 12volt lighting and fans and pumps and all sorts of toys, just for learning. None of this will be critical, so used batteries and no inverter should do just fine.

    If I am swapping battery banks now and then, how do I make sure panels are not connected during the changeover? I don’t want to mess with the wiring by putting extra stress on the Renogy connection terminals. I am thinking of putting a 2-pole industrial-rated "light switch" on my panel outputs to kill the panel feeds when I am playing with batteries. Is this just overkill? Should I simply cover the panels or maybe do the changeover when the sun has gone down?

    I also intend to expand the system eventually and/or build more of them out here for the neighbors. This one is my "free" test system/teaching system. I figure to suck these old golf-cart batteries until they have no life left, and then we can use them for our core replacement when we are buying other, new batteries for boat owners.

    Will reminds me of a lot of my classmates in Navy IC "A" school. We were young and very enthusiastic about the education we were receiving. They always reminded us how much our schooling was costing the US taxpayer and that in the end it was the equivalent of a two-year Associate degree in electrical engineering.

    Thanks for the help. And, let’s pool our $$$ and buy Will some real electrician’s tools! Using a ‘tweaker’ screw driver to tighten the charge controller screws??? Using a crescent wrench or pliers on nuts and bolts? Both are big-time no-no’s in the construction industry.

  45. etherflames on May 7, 2021 at 1:48 am

    As others have said this was simple and able to understand for a beginner looking to do a setup. Been looking at vidz all day but for some reason this one just made it all make sense…

  46. 17 NIGHTS on May 7, 2021 at 1:49 am

    Yaaay I just learned how to put my solar together perfectly, looks like I’m powering my home made go-kart forever!

  47. Alessio Andreoli on May 7, 2021 at 1:50 am

    Great work!

  48. JeanCast on May 7, 2021 at 1:50 am

    Thank you for breaking things down as simple as possible!! Now I’m ready to build my solar panel system!

  49. Jordan Hurd on May 7, 2021 at 1:53 am

    I want to build a 600w solar panel array. Which one of your all in systems do you recommend? I’m happy to buy products that will give you a commission if you can point me in the right direction in terms of panels, batteries, charge controller, and inverter (looking for best value.)

  50. Gale Cooney on May 7, 2021 at 1:53 am

    EXCELLENT VIDEO.. I am converting a 20 ft. storage container to store lawn mower n workshop..I am planning on using this system.
