  • Just got my CALB cells! 16 cells = 24volts = but they came with BATTERY CRABS!

    Hey guys, I juts got my CALB cells from China (after watching Will review them), it took two months! But here is a video of me unboxing them and discussing how I will use / configure in my solar array which is a cargo trailer conversion into a motorcycle hauling travel trailer... Cargo Trailer...
  • Is this normal?

    I bought a 12volt load center / fuse block from Amazon. the voltage going into it from my 24>12volt converter is 12.3volts consistently. But When I put the multimeter on the connectors, I get about 10.8 volts. None of the wires are getting 12volts from the bus. Is this normal? My Iceco fridge...
  • How to test new MPP Controller with no batteries?

    I just got a brand new 24v MPP Solar All-in One charge controller/ inverter unit from China, based on Will's recommendations. I have panels and this unit, but my 16 battery cells have not arrived yet. All I have is a car battery and a small 12v motorcycle battery. What is the best way to test...
  • No PV recognized on my MPPT LV6548 all in one system?

    I have a brand new MPPT LV6548, having had good experience with the 24volt version. I just set up the system today with 4 SOK 100ah batteries in series. Batteries are fine and the MMPT sees them fine. I dont have any utility power source, but the AC out is blowing a floor fan using battery...
  • So how to connect this to an all in one MPPT controller and 12v bus?

    So with this setup, Do I just take the bottom positive and just run it to a pos. bus bar, that then sends out two pos. lines - one to my MPPT2424 in, and the other to the 24>12volt converter? Sound right? And run the top negative to the MPPT neg in? Thanks in advance for help!
  • Showcasing your solar components in acrylic boxes - like a giant gaming PC?

    I am starting to build a system for my cargo trailer. Instead of hiding it in a plywood box, i think it would be cool to put all components and wiring inside a casethat has an acrylic / clear / plexiglass type front so you could see it all. Of course the wriing would have tobe clean and the...
  • What breakers or fuses do I need for a solar fridge simple setup?

    I just bought a small 6cubic feet solar refrigerator (12/24v) that I need to build a temporary rig for. It pulls 53watts. Will be using for 2 months in Dallas where we get a fair amount of sun in the summer. My plan is to run (2) 240watt poly panels (used ones from SanTan solar, already...
  • 48 volt safety

    I am building my first 48 volt system, and I hear Will's comments about getting shocked and being careful, but im not finding much information on how to put safety in practice. Does any have a resource or list of DONT's when it comes to working around 48volts? When a discharge capacitor is...
  • Building a cargo trailer conversion to travel trailer for boondocking

    Happy to be here. I've been enjoying Will's videos for a few weeks now and I'm starting to buy my gear but have some newbie questions, of course. I have purchased a used 8x18' cargo trailer that I will use to haul a motorcycle to national parks and National Forest land, where I want to be able...
  • What are the wiring options when you have 10 panels? Series with different total voltages - do they play nice?

    Newb question; If I have 10 identical panels, each with open circuit voltage of 20volts. And I have a max 80volt all-in-one MPP inverter/controller.. what are my options for series/parralel of the panels? a series of 5 panels is too much voltage. A series of 4 is fine, and I can parallel two of...
