Great video Brad. I see these no name MPPts on Amazon and always curious on how they would perform. You doing videos on these unfamiliar products is a great help for the solar communities.

Looks great. Everyone needs backup these days. Thanks Brad.

I mean I know that sounds weird but when I was having the erratic voltage jumping up and down and charge controller turning itself off and just blinking with the powmr I was worried to walk away from it with it hooked up thinking it might destroy my batteries and when it was the leaf batteries I worried about fires. Now with the victron it just charges smoothly and everything just works.

Another nice find Brad. I was impressed with the last 24V battery builds efficiency that I am now building a 48V system for my camper trailer. I'm using a different approach to solar charging - one mppt boost converter per solar panel (4 solar panels) all feeding the 48V battery. A little on the edge, but I think it will work. The boost converters were pretty cheap, but multiply x 4 and it gets up there. Still, I'll have 4 completely independent solar chargers, so this must amount to exceptional reliability.

beginner here, trying to understand voltage. if i use say 2 100 watt 12v panels, i connect them in parallel? what if it were 2 100 watt 24volt panels? also, why would you choose either 12 or 24 volt panels? one is superior to the other?

Can u series four 12v 100w panels to charger a 12v battery bank. Or you got to parallel the four panels with this mppt charge controller

For 33 bucks if it lasted a year I would be happy. Nice!

I questioned using this on a 12v RV because of it being positive grounded. I was told by some at Rich solar that it is unusual to be a positive ground but that it doesn't matter as long as I don't ground it or the panels. There is no grounding wire anyway. 3 days in it is working

How do you reboot this thing? Got a E12 error code and it won't do anything now.

it went up to $47 but the 40amp seems to be the best deal

I purchased Sunthysis 20A Everything works as described Except one thing: For dual light control when I tried to turn it on only 4 hours it still on whole and only shut down at dawn Please give me an example to make the controller to turn on only a period of time such as turn on at 10:00 pm and turn off at 11:00pm or turn on sunset and stay for 5 hrs

I purchased the 30A Sunthysis, started testing it out. Unfortunately neither of the USB ports will charge anything (tried conencting it to multiple 12v batteries with no luck as well as multiple USB cables and devices) Despite going thru the settings and setting it to "custom" to adjust the charge parameters for my 12v ,3S 18650 Li-Ion battery (which the voltage range I want to opperate it at is 9.6v-12.6v which means im running the individual cells to 3.2v-4.2v) and it will not charge it. Not sure if this MPPT charge controller is good for custom batteries. Looks like it would be good for the 12v/24v LifePO4 batteries though.

The charger controller was $53 when i purchased it last week. I just checked the price for it now and it's $92. I manually selected the LifePO4 battery and the controller rebooted and gets the error 11 right after. Not sure how to fix this.

That is not bad for the price. I wonder if it does better without maxing out the solar input on 12 volt? I believe it said 260 watts max input and it was around 261. I would say either put fan on the load side to help with the heat on it or mount it to an aluminum panel or something to help dissipate the heat. A small 12 volt computer fan should do it I think. I wanted to check to make sure I got it right, when it says max input 260 or 400 watts or whatever it is rated at, is that the solar panel input or max of what it will put into the battery?

@BradCagle

Max that goes to the battery. So 20a x 12.8 = 256w but as you know getting closer to full 13.8+ you would get 276w
