- My 1st run, doing a video on the performance of the kit. Incan say for now it all appears to be working as stated. So far so good, next would be to learn well the f7nction of the charge controler followed by incrementing the load keeping track of performance. Hope I gave so help and hope to someone out there, good day.

I have 4 of the 35 amp hours Harbor Freight batteries with 8 of the 25 watt panels. Good stuff! Blessings 🙏🏼👍🏼
👍 Excellent demo and video! 👍
I have the smaller single solar panel and a 400 watt for my Dremel carving, but after seeing your setup I think I'll upgrade to a larger 4 panel, 4 battery and the 750watt.
I don't draw a lot of power with the Dremel only, but seeing your fan makes me think it would be nice to have a larger modern and more efficient setup that can handle a fan AND other small woodworking tools that can run at the same time and still keep up without hearing the overload all the time.
Good to see that you DID connect the positive and negative cables in an "opposite feed" configuration. By charging/discharging from "opposite ends" of your battery bank, you have effectively balanced the voltage/current loading/charging of your system.... One aspect to consider if/when you may build another system, is to use a 24 or 48 volt battery bank and inverter so as to greatly reduce the voltage drop caused by higher current and with running a higher voltage set up, the wire size doesn't have to be nearly as large in the AWG sizing.... You said you used what you had on hand, but, I "know" that you will want to dick around with building another system and my suggestions to use higher voltage components will reward you with MUCH better efficiency and performance.... Good video....
Great start...! I'll be testing my own trial and error by Friday on my landlord's 5th wheel.
Great video...Just subbed...keep those videos coming!!!
A good rule of thumb is every 100 Watts at 120 volts ac is roughly equal to 1 amp so 100w at only 12 volts DC would be 10 amps so your fan is 2.9 amps at 120 volts ac that would be 290 W roughly. But once you invert it you have to remember that load is being drawn from the 12 V so that 2.9 amps is actually closer to 30 amps DC I would say you should be able to run that fan on high for roughly an hour and a half to two hours with those batteries you have and no input from the solar.
Yes, I purposely waited for nightfall so I can just used the batteries, not using the battery maintainer but tomorrow plug the solar panels to see how quick they charge back to 13.8V. I saw today the controller said at 3pm the panels were generating 14.1V, thats if Im reading the controller correctly, whichbis another learning adventure at 60. Lol
@@mostrogolf22 the different modes go like this. The first mode or the first screen where it was showing your battery voltage at 12.6 V that was the main screen that shows you voltage coming from the panels and going into the batteries. The next screen where it said 13.1 or 13.8 whichever one it was, that was float charging mode. The next screen when it showed 14.4 was where you set the charger to just dump as much current as possible into the batteries. There is really no reason to cycle through the options. Leaving it on the first screen makes it fully automatic and the solar panels will charge the batteries until it gets to about 80% full then it'll switch to float charging.
If I'm not mistaken the charge controller came with this kit only does 30A max on either 12v or 24v setting. So it can only parallel plug 2 panel at 12v or serial/parallel to 24v at four panel.
The controller is a 10A just enough for the panels in the 100-watt kit.
Maybe if the air has a lot of moisture in it one of those fet transistors will pop or if the timing generator is off. You might hear a pop. Its possible. Lucky they are pretty cheap.
I LOVE everything but put a fuse on the output of the batteries please! You dont want to challenge that battery pack to a fire if something somehow gets shorted at the output.
Totally agree, I still haven't been able to purchase them. This was just the 1st Run so I can discharge the batteries a bit. Today I ran the panels to see how they charge the batteries. Yesterday the batteries read 12.5v from 13.1v when I shut everything down. I ran a med size shop fan for two hours to discharge the batteries some. This morning the bank read 12.5v. Started at 8:45am and shut it down at 12:45pm, at the two hour mark the digital display was indicating 13.1v. When I shut everything down it registered 13.4v. I left it at that. Yes the fuese to all positives cables will be done, thanks for reminding me. Good day.
@@mostrogolf22 how about operating a computer? How long will it last?
@@luiggispeed4081 that will depend on the cpu and power supply of the computer. My gues a couple of hours
120v at 2.9 amps = 348 watts
You need to double nut those stainless bolts on the batteries,, expansion and contraction cause the m to loosen 😮😮😮 f j b 😊
