Electronic Basics #29: Solar Panel & Charge Controller
video description
a lot of common solar modules seem to deliver 12V and typical car voltage is also 12V. Does this mean that using a big enough wattage (100W Module) i could charge USB-C devices directly (using standard USB-C car chargers) from a module, by also transforming the least amount of energy into heat? Do i miss something?

I have a general question, Can a dc-dc step up module be used to maintain a solar panels output at 12v 2. 5amps, when panels out drops significantly? My solar panel is 12v 50watts one and I see the output fluctuates when I connect a 19v, 3amp laptop charger(around 60watts, I wonder if one of these step up modules can help

In 6: 33, the measured open circuit voltage (Voc) appears to be 5. 4V, however, in 6: 45, it appears that the rated Voc of the panel is 22. 6V. What is the reason behind this drop in Voc on the measured value? I am assuming the Voc rating shown on the panel is indeed for the panel you have done the measurement.

So I'm trying to size a 30 amp service at 110v. How many ah do I need when it comes to batteries before my 8kw inverter? IDK if it's 8kw in 110 or 12v but I'll never draw the 65amps this thing can put out. 30 amp Max. I can size my panels etc later.

Interesting to see that you also fell for the MPPT scam. The one shown in this video is actually not an MPPT type controller. The MPPT on its case is the name of the company manufacturing these.
How about making our own?

Hi! Dont know why this video was not recommended to me a few weeks before! It is a very interesting video on solar panel. And i am making a MPPT charge controller for my 12 V 10 W panel to charge a 12 V 1. 3 Ah battery.

Some guys cant ven pay such solar panals and you break it =(
Please make a video of MPPT Charging controller, it will be great. I need one but I don't found any good cicuit for a DIY charge controller.

Hey Will, great video, bt why are you adding a fusible link to the inverter when it has a built in fuse under the red cover? Just curious if you were lowering the amperage of the output?

A small error: The MPPT M20 is a PWM Charge controller. Ok, the name remember us a MPPT but the price and the specs will remember us that it's a 20A PWM =)
