  1. jeeze expertvillage again they suck but to rahmanron Green is NEVER hot in DC red is hot black is ground … in AC black is hot white is neutral green is ground … dont know what planet your from…

  2. hmmmmmm…Armored cable being used outside???? Might want to check the UL listing on that one chief. And the NEC….

  3. @juggernautxtr my bad, that would be 41 amps at 12 volts 🙂 obviously that doesn’t apply here. Depends what total volts/amps he’s got running from the array. No idea..

  4. @dhymers
    12 gauge is only good for 20 amps
    10 gauge 30 amps
    8 gauge 40 amps
    why we have a book called the national electrical code.

  5. so you’re going to install a 40amp fuse when you need a 15amp one …. (for the CC)?
    12 gauge can handle about 41 amps, thats cutting it a little close isn’t it ?

  6. Bx / Mc not rated for outside , indoor cable only . where’s the red antishort bushing before you install that connector Bud !!!!!!!!

  7. now we have the playlist for this series
    click my screen name and go there
    Thanks everyone

  8. 500w angle grinder ect is gonna make the inverter pull 50A from the battery that’s why the 20A fuse blows, try using a higher rated fuse.

  9. Be smart – don’t pay any more electricity bills. more info: (Copy to your browser’s address bar)

  10. Where you go to school 1-800-Im-a-HACK. One code violations one after the next there buddy…

  11. the inverter must be plugged directly to the batterys in the inverter socket on your charge controller.

    Do not use the 12V output on the charge controller

  12. therealvirginiawind

    I installed a 130 Watt panel with two marine batteries. I have fused the system with a 20 amp auto fuse going into the charge controller and into the batterys. When I plug in a higher amp appliance (500W food dehydrator, angle grinder, etc) to the inverter I blow the batter fuse. What am I doing wrong?

  13. OK first black is neg do you need to change both colors and add that blue jumper to make this a real HACK job no permit here

  14. hummm?………….using solid wire for DC solar??………going to get power loss, from what i understand, you need to use stranded wire to help reduce the power loss of DC current!

  15. i totally agree. he should be hooking the power source up LAST..not first. we were taught to isolate the danger. some sensitive electronics would not survive this guy’s method.

  16. Well this guy probably knows where to hook up the parts, but it is obvious he is dangerous when considering the code issues and grounding.
