I just bought the Sunrock 20 after some study to replace an older PWM controller. It's nice to see I made a good choice. Like Robert Meyer below I use my solar for ham radio portable operations. I left the SAE connectors, but installed Anderson Powerpoles on the ends of the pigtails. I use red/black for the output side, to match those used on the radio gear and everything else on that side of the controller. On the solar panels, and the input side of the charge controllers I installed green/black Powerpoles as an indication that all of that is 18v so as to not mix it up with the 12-13.8 volt connections.

[@kalypsoisland]

That ac looks interesting. Love the terrier.

[@robertmeyer4744]

I have the 10 amp version and works great. using for HAM radio portable use. I cut the SAE off and put on Anderson power pole connectors. the only thing I had is some RFI noise in AM/SW radio. with ferrite snap cores buy controller on both sides and took that noise out. have not tried the 20 amp 24V yet. the small size works for me. we use Ammo can battery boxes for our portable radio stuff. I do have Victron controller and that only slightly better . and it's bigger. did not fit in my 50 Cal box with battery . the 10 amp ones does and that 20 amp one will to. nice testing .

[@BradCagle]

Nice! Yeah, these little guys are impressive, and great for DIY power banks like you're mentioning. I was surprised by the lack of heat, especially since there is no heat sink exposed. I gave this one to my Niece, and her Husband. They have a teardrop trailer that has that SAE connector on the side for solar charging, plugs right in. I missed it so I got another for myself, I use it in my Xterra overlanding build. I have a 380w panel on the roof rack, and run it to a 24v 100ah battery. Thanks!

[@saxmusicmail]

Robert, good tip about the noise and ferrites. Thanks.

[@Zbee167]

Good stuff! Thanks for sharing.

[@kalypsoisland]

Always learn a thing or two or more from your easy going, stress free videos...

[@BradCagle]

Thanks. glad they are helpful :)

[@mikebagg9155]

Way to go on the comparisons with different controllers. Much appreciated. Thank you so much. I'm buying the portable. Thanks :)

[@BradCagle]

Glad I could help!

[@hectorquintanilla5520]

Again great informative video.

[@BradCagle]

Glad it's helpful. Thanks!

[@Hooghan04]

Thanks! Looks like a nice little unit. Would you need a fuse for it?

[@goodcitizen4587]

Fun video. Sub'd!

[@BradCagle]

Thanks!

[@ww2069]

sweet vid Will have to get!!! Loved the fact you keep checking temp of item but never see on app it shows internal temp. LOL lol LOL lot of good info

[@BradCagle]

LOL, yeah I think I noticed somewhere around the end. Thanks!

[@patricioelosua5886]

How would you think this would hold up in a 4wd engine bay? In regards to it not having a heat sink? Great video, thanks for the detailed analisis!

there are 2 -20 amp charge controllers one with Blue tooth and one without. Its always nice to have Bluetooth i guess

[@BradCagle]

@@mannyfragoza9652 Yeah, I would totally pay the $11 premium for the BT :)

[@MattLesak]

Great review!

[@BradCagle]

Thanks!

I like your reviews. Straight to the point and you open stuff up. Please don't change ;-) @@BradCagle

[@BradCagle]

@@MattLesak You got it! Thanks

[@cccmmm1234]

Victron have a better marketing department than their engineering department. MPPT really shouldn't take that long to stabilize.

[@MOKuma1Neely]

I love watching you to see something new and a little different. I’m not getting your discount code to work on Bateria’s website.

[@BradCagle]

It's sooo exciting to get something new/different. BTW I just tried code and it worked for me "Brad Cagle15" without the quotes, and the space between needs to be there. Weird they added the space. Thanks!

[@natesdiysolar]

Cool little controller. SAE automotive connectors

[@BradCagle]

Yup, I like it!

[@TOMVUTHEPIMP]

I hate those SAE connectors. Id cut them off and put on some Anderson.

[@natesdiysolar]

@TOMVUTHEPIMP personally I like xt60 for these types of things

[@PWoods-cd6tk]

Definitely a more realistic price for a 20 amp mppt than what you had last week. I still think the best bang-for-the-buck for small, short wire (< 40 ft) systems are the Bouge RV PWM Li controllers.

[@marka7519]

MPPT maximizes the power coming from the Solar Panels. Whatever little money you save by buying PWM controller, you more than lose on solar panel efficiency, and have to buy more solar panels to make up for it. Those that are mobile and space contained, or when there are only so many hours in the day when you get good sun, the inefficiencies of PWM are magnified. I would never waste my money on PWM.

[@PWoods-cd6tk]

@@marka7519 have you tried one? My 10 amp in my shop makeS 75 and 80 Watts consistently with a 100 watt panel and gives me 100% charge on my lead acid battery everyday. My 20 amp Bouge RV PWM with my HQST 100 watt panel pushes over 85 watts all the time. I have 2, 30 amp Bouge RV PWMs that when running 400 watts were bringing in 300 at 40 feet of 10 gauge. What I was saying, is for short runs, PWMs are just as good as MPPTs. Now, at 60 ft I'm bringing in just over 65 percent with a PWM when it's in the 80s and 90s. Over 100 even the 48 volt MPPT goes down. With 10 or 20 foot runs, you will not see a difference. And the price is less than half with the same maximum voltage and wattage.

[@procrastinator1842]

​@marka7519 Not to mention, when your battery voltage is low, the PWM pulls the pv voltage right down, reducing your panel output even more. I didn't realise it, but going from pwm to this mppt meant double the output in the early hours of the day. I.e. with the pwm I was getting 28W, with the 10A mppt I was getting 46...

[@benkanobe7500]

What charge parameters do the different controllers use for Li at fully charged? Do they trickle charge the Li or do they stop charging? At what voltage? So many controllers use nearly identical parameters for Li as for AGM which is not good for Li long term.

[@pocketchange1951]

👍👌❤🇨🇦,gr8 review

[@BradCagle]

Thanks!

[@daveyd0071]

It's not getting warm because you're i/o is very close to the battery's charging voltage, now input 75V and see how hot it will get.

[@BradCagle]

Yeah, you're probably on to something. In the manual it limits you to lower PV voltage when using 12v

[@alenles]

Is it possible to connect on this controller a 24-volt panel to a 12-volt battery?

[@gregmeyer2294]

Do you need a heat sink with it

[@pocketchange1951]

👍👌❤🇨🇦, for a small setup it might be ok , not for my 3240 watt setup though

[@BradCagle]

Oh yeah for sure! Thanks

[@jamesalles139]

after ten minutes, what changed? The battery has been accepting charge all along.

[@Golfreak]

Amazing video. Between you and Roland, you guys review some obscure solar stuff that we don't see everyday. Amazon has the Bateria 60a mppt for $90 right now. Tempted to try it. I know Roland got his hand on one. Did you get one too ??

[@BradCagle]

Whoa, that's a sweet deal. Wonder if it's good?

[@Golfreak]

@@BradCagle I asked Roland and he said yes if you get the BT adapter. He said Bateria just sent him one and he will have a full review soon. You guys are doing a fantastic job.

[@BradCagle]

@@Golfreak Awesome can't wait for his video! Thanks :)

[@marigri2464]

Is it a true mppt

[@CheekoAshOverLand]

How does that zero breeze do? Thinking about getting buying one.

[@BradCagle]

I haven't had a chance to really test it out. Hoping to get around to it before it cools down too much outside.

[@BenMitro]

Just goes to show size isn't everything! I hope the release a 48V version.

[@BradCagle]

Very true! A 48v would be sweet!

[@procrastinator1842]

Hi, did any of the other apps work with the batteria power mppt?

[@SansanWannaSanta]

It doesn't work with others but the charge pro 2.0

[@Roll2Videos]

What's up with the air conditioner?

[@BradCagle]

I need to do a video on that thing. I bought it. They wouldn't send me one, we'll they offered me 30% off.

[@Roll2Videos]

@@BradCagle it looks cool,

[@saxmusicmail]

IF the controller is 100% efficient, as they say, it should not get hot because it is not wasting energy into heat.

[@mannyfragoza9652]

I'm actually looking for a change controller like this with the leads installed so i can run one battery wow. BTW i have the same App for my BoughRV charge controller i dont think its all that accurate? When my Renogy Shunt meter says 13.6 my Charge controller App says 140.0 Im not sure which one is wrong. Ill have to test with a volt meter and see.

[@BradCagle]

Usually your charge controller will read a higher voltage because it's the producer, and you'll have a voltage drop over the wire to your shunt. This would be while charging. If there's not charging current they should see about the same.

[@mannyfragoza9652]

@@BradCagleThanks Brad that def clears my problem up for me.

[@BradCagle]

@@mannyfragoza9652 Anytime!

[@stevenseigneurie5073]

Brad, I see this unit is not offered with Bluetooth anymore off amazon or the website? is this going to stay that way? I reached out to the company and have not heard back yet.

[@BradCagle]

Maybe out of stock on amazon, but they do have the BT model on their site bateriapower.com/products/20a-mppt-solar-charge-controller-with-bt-app?variant=46481955946788
