You’re sharing knowledge from a user with experience. Sizing the items in the setup is not easy to do without experience.

Many of us are totally satisfied with using PWM controllers. I am not a power hog in my RV and my 400 watts of solar panels, PNW controller and two deep cycle batteries are more than enough to handle the refrigerator, TV, laptops and lights. I think I only paid $14 for that controller on eBay.

Will, thanks for this succinct but valuable video. I’m living in the ever so cloudy, ever so northern PNW. I’m part of a group building an amateur radio emergency network on remote, isolated small towers. The solar/battery system is about 50% of the kit cost and increasing the efficiency is paramount. There are a lot of YouTube videos on solar but I keep coming back to your channel for clear answers and actionable suggestions. Thanks again!

Your presentation gave me confidence that a $13 PWM on our small sailboat, running as back up for essential systems like nav lights, depth sounder and to back up GPS and chartplotter was fine. No need to spend over $120 on a solar system! Sail primarily in summer on warm sunny days, stays cool in bottom of lazarette where charge controller, batteries located, less than three feet of wire to connect. 12 volt 35 amp AGM battery x 2, plus starter battery. 100 watt solar panel. Worked great past two years.

WOW, you are so great and have taught me so much... I knew nothing...I’m just an old 68 year old woman👵🏼 trying to learn. Still trying... love you.

[oursilly]

Dude. This video rocks and it's 4 years old. Thank you.

[dtvking]

Couldn't agree with you more Will. I just changed from PWM to MPPT and over the last week, I am getting 2 to 3hrs more life from the batteries in part cloudy/part sunny days here in North London and I'm seeing a 4 to 5amp output from my panels in just normal daylight (no sun) when I was getting nothing on PWM without sun. Well worth the upgrade.

[AJOTECH]

You know about that. For me I learned from you about the solar system. I made my own solar powered. And I made my own battery power box. Thank you for your advice, support and suggestions.

[mosaabkhalifa]

The best video that explains what MPPT and PWM is designed for. Thanks Will! Sending best wishes from Libya!

[heathbarnett]

Thanks for clarifying Will! I found myself comparing the two while watching your last video.

[craigwallace]

Thank you for every single one of your videos, Will. Your efforts are appreciated more than you know.

[brianstewart]

I came here seeking knowledge and you do an amazing job at transferring knowledge.. Man, I really appreciate your videos.

[MrWackozacko]

I honestly would never waste my time with anything other than the best Victron MPPT anymore, have gone through a bunch of PWM chinese ebay specials over the last decade. But my victron 48v20A has had 300kwh put through it over the last couple years and is still going strong

[Engineerboy]

Plan to build an off-grid solar system soon. In the mean time I'm going to be watching a lot of your videos, Great content! Thank you!

[martinc]

Highly recommendable information shared here, i am electrician, not working on the job for some years, and the solar industry has improved a LOT in the past few years, which makes it overwhelming even for people like me to get the big picture whats best right now.Thanks for sharing.
Field experience is crucial, and its great to have a channel like this with the pros and cons of all products involved to make it run optimal.

[MertTheDragonReborn]

This video helped me a lot. I had an assignment about the differences between MPPT and PWM charge controllers for a Lab-Course. This Video saved me so much time and clarified the most important parts in a short span of time. Greetings from germany!

[peterhutchings]

Awesome video will. Happy to go down MPPT route now. Big shout out to Oregon or London people :) UK resident here 🤟🏻

[CorpsMedia]

Hey man, I don't know your background but you make some incredible videos. I'm an electrical engineer of 10 years and I'm just starting to get into YouTube showing people about electrical installs in vehicles. Any time I have to cover a topic on solar I will be refering my viewers to your videos 👍💪

[wayneleary]

Cheers for the vid, , , made my mind up MPPT..CLEAR AND UNCONFUSING, Living in the UK i need an MPPT.. WELL DONE LAD
