Solar Charging 12V Batteries - Too Easy!

Unavailable from the Amazons @3.31.25

F Amazon!

In 2 or 3 days😂

They also sell a wall charger for these that you can use in your house

3 days...kind of too slow for a single battery lol. Needs to be able to go from 30% or even 50% to full during a single day during daylight hours to really be something that can be used every day. I could see that charge speed being good for something that's not used everyday, just to maintain a charge on the battery though. Like a car battery in places that get below freezing for most of the winter. When maybe you only drive your car for a couple hours, once or twice a week, or less.

days?

Brother you just single handedly solved my entire solar system. Im off grid and all i needed was one 12v battery. Keep up the good woro, God bless ya!

Why on earth would you compare pricing for expensive 30 amp controllers to your cheap 10 amp controller.

This short is not awesome.

But can you still use your battery while charging ?

dude, you rock

I love cutting wires and making cables though it makes you feel like you’re not just an assembler monkey

Nice dude

Your web site made it easy to put a system together for back up power for my amateur radio station. Bought most of the same things on Amazon and felt confident it would all work together OK. One detail to be careful about with the connecting cables...I needed to run a few feet to reach indoors to the controller and I used cables that had SAE connectors. After looking at the whole assembly it was easy to see that polarity could get swapped if you weren't paying close attention. You might make an update to the site placing strong emphasis on watching cable polarity all the way from from the panel, thru the controller, and out to the battery. Definitely could ruin someone's day if this happened.

I bought one to charge my 20ah LFP. I paid 25 dollars.
I would never use this small 10 amp solar controller to charge 100ah battery. I would spend an extra 20 dollars and buy a 40 amp solar controller and charge in a few hours and not a few days.

You're an amateur. Please don't suggest anything about solar.

Lol ur so dumb if u think it’s a real mppt for $40. Ur getting a mini pwm for $40. Its cool, I seen a crackhead using it to charge his battery bike.. but its just that, something crackheads use.. this is most janky thing ever

NIce controller!
Do you see any inconvenience if I use this device to charge a battery while, simultaneously, I use the battery to power a device?

That is NOT an MPPT charge controller. There us physically no possible way for MPPT to be that small.

Is there a way to have this connected while at the same time using the battery power and water pump?

I’ve two group 31 and one group 24 12v AGM batteries in my boat which I put in a yard for about 8 months with no electricity. I would like to put a small flexible solar panel on the boat cover and hopefully charge all three batteries in parallel with one of these controllers? The batts are fully charged and only need to be maintained with a small float charged. I am concerned with the dissimilar size of the batts but don’t know enough about it my concern is valid. The two group 31 AGMs are normally wired in series for 24volts. Maybe what I need is two of these controllers and two small panels but I’d like to avoid the added expense. Any comments, concerns and recommendations are welcome.

How long does it take to charge it from 0 to 100?

Can I use a 12v 20watt solar panel with that controller and battery?

Can I run 2 100w solar panels in parallel through this controller to charge a 12v lithium 100ah battery?

how much

This is a great video, but I have a question. if I have 4 100ah 12v batteries (same everything. Can I still use this to charge the 4 at the same time if I connect them in parallel? or would it be series? Assuming I top balance them first, would this same setup allow those 4 batteries to be charged over time with the solar panel as if it was just 1 big battery?

That only works if you have a singular 100watt panel though, right? What I mean to say is, wouldn’t one need to have a bigger charge controller if they wanted to charge their batteries faster and with more ways going in?

Nice❤

I like that controler...mppt chargee controler

Link takes u to a different one u have to install. I want this one plug and play 😢

Bro how maney watt your solar panel is? Plz reply and how maney time need the battrey to full charged

Mppt controller, " NOT " Don't be fooled..... It's a fancy PWM....FYI

All the stuffs and exact brands available in lot chinese online store. China is the best

Where are the links? Amd where did you get the solar panel from ? Gow much was it?

I got this to charge my lifepo4 bat when it gets low when the sun is up. It turns out when the sun is up it does not use the sun to start to wake the bms.

Hi, would leaving the battery under the sun degrade the battery's life span due to heat?

Sir pamine😍

Mppt in this size over 2 A is not posible

Is the Charge Controller weather proof?

Hoe long eoupd it take to charge a dead marine battery. Also. Woupd these keep charge in battery during use??

Comes up at $90 for the charger and $45 for one cable for me? I know that's Canadian but that doesn't add up lol might as well get a victron 100/20 and have it last forever at that price.

Are you sure its a real MPPT chargecontroller? Most cheap (from china?) are not MPPT but they work - not as efficient as MPPT.

Yes but the hundred dollar charger puts whatever the solar panel can, not 60watts.

everyone should be doing this, fighting to make energy prices cheaper by doing yourself. he said it himself, 3 steps literally.

Cant find your charge controller i have even been through your links can you help .

appreciate the content brother, exactly the channel ive been looking.for. keep em coming!!! nice work!

Nice little unit, lots of cheap mppt controllers out there mine has a spot to connect a small light or fan and has two 1.0a USB's built in it n handles 20a for 40$, You can find portable solar kits with built in mppt controllers with different adaptors

Do you get them of amazon
