  1. Had me going there for a second, these are not 400W panels, they're 4X100W panels. Oh well! 😊 I wish HF imported bigger panels, I would love some 200 watt'ers.

  2. I'm surprised the Harbor Freight controller handles that many panels.

    that is the weakest part of their kit.

  3. Your batteries are your Achilles heal, you need 100ah Iron Phosphate type. But I know they are expensive.

  4. Love seeing HF set ups. The 100W (200$) kit is a fantastic entry level solar array for exploring the technology.

  5. I wish you'd talk more about the hot water solar heater instead! That installation looks beautiful.

  6. YOU HAVE A VERY NICE SYSTEM . THAT BEEFY INVERTER LOOKS SOO POWERFUL , 5000 WATTS I ASSUME – IS IT A JUPITER INVERTER ? ONE OF THOSE TOP INVERTERS MONEY CAN BUY . YOU HAVE IT MADE WITH THIS SYSTEM EVEN WITH THE 400 WATTS HARBOR FREIGHT PV MODUELS OUTSIDE IS GREAT . KEEP IT UP AND RUNNING . WE PREPPERS ALWAYS HAVE DIY POWER RIGHT AT OUR HANDS DURING ANY SHTF SITUATION OR TO SAVE ON THE ELECTRIC BILL . WHEN YOU GET A CHANCE , CHECK OUTMY SOLAR VIDEOS , HIT LIKE , LEAVE A MESSAGE AND SUBSCRIBE . MAY THE SOLAR BE WITH YOU .

  7. Lol..I bought two more marine batteries today…I've got 8 now..I rewired all my stuff awhile ago..shortened some cables..I've got 490 watts of panels and 340 amp hours at 24 volts..I just buy 2 batteries a month at the local Autozone..I'm hoping these two will kinda be enough but I'll find out when I get these other 2 hooked up..I had no idea 1/0 wire was so pricey..I had to get a few feet to add these…I've got an Aims 2000 watt inverter/charger…it does pretty good but the days have been short so not enough hours to charge really well this last week without the charger so I figured I just needed more battery…

  8. I hope the people in Texas to do this. 11-year-old boy frozen to death in his house mobile home please people do this for yourself.

  9. I ran up on your video. I like the design you have with your panels. Lower them during snow or hail storms. Bet they make pretty nice shade during the summer.👍✌️

  10. i also bought four of these "100 watt" kits. when i got it all hooked up i measured the watts i was getting back around june 19th 2020, when the sun was bright and strong and just about the longest day of the year and i noticed i was not getting close to 400 watts. after quickly learning more and measuring more i figured out how they measure the "100 watts" vs what actually happens. if we can pretend that the four 25 watt panels are just one 100 watt panel it makes this easier to explain. each 100 watt panel is 24 volt open circuit voltage, each 100 panel will max out at 4 amps. we take 24v x 4a = 100 watts, which is what they claim we get, but what we actually get is 14.4v x 4 amps = 57.6 watts, this is off by 42.4% lol. so my "400 watt" system was only producing 230.4 watts, and this was only when it was bright and sunny and the panels pointed straight at the sun, the slightest tiny cloud will bring the amps down. i returned all but one 100 watt kit so i could continue to learn. this kit has taught me a great deal about solar, but another thing i learned is cost. that harbor freight kit is great for learning on and powering a few little things, but not only does it not scale well due to limitations in the controller and wires, but its expensive. so much more expensive than using better stuff that will actually give you the specs they cite. those harbor freight kits range from $150-200 a peice, so $600-$800, for 230 watts, not 400. also, "400" watts is about the limit you can push this system. the most amps you should try to make that little pwm charge controller handle, i think it has a 20 amp fuse in there, and my 400 watt harbor frieght system never made more than 16 amps, if i remember right, and things were getting hot at 16 amps, 16 amps is way over spec for those little cables. i was nervous leaving the house knowing things could catch on fire. anyways back on point i just bought a mppt charge controller for $100 and one 400 watt panel for $350, for a total of $450 and i will get all 400 watts, provided the atmosphere corporates and i can scale it up to 100volts at 60amps =6000 watts and still maybe keep charger side of things at 12 volts. one day i will make a video going over all of this. great setup, great video, i am happy to see people getting into solar, if nothing else if you loose power for a few days you can charge cell batteries and keep some lights on, maybe even power that blower moter for the heater. also, lithium batteries have coming down in price fast. 12volt 240ah for about $500, that would take 4.8 deep batteries @100ah to match that watt hour output, which would cost ($960) more than the battery i mentioned, plus its light and you can pick it up easily with one hand.

  11. Xvideo thanks for sharing. You're very out of breath just walking around you might want to get that checked out. Make sure your lung capacity is at its best. If you're a smoker you should stop.

  12. That charge controller is only made for 10 amps, so you're only really getting 10 amps max of charge which is like 200 watts if you upgrade your charge controller to a 40 amp your batteries will charge so much faster

  13. Nice job….I bought 3 HF kits when I first started. Then I found 100 watt pannels on Amazon for 99 bucks. I almost bought a 4th kit but saved some money just adding these to my system. I have some videos. Go checkem out☺

  14. Hello, I am interested in this project like you are, but I noticed that you have all that power going to a small charge controller. Don’t you need the 500 watt charge controller that they sell. Don’t forget that you will need a couple of fuses that connect to the batteries, so that if there is a short or some other problem, fuses will protect your equipment and other properties.
