$50 Powerwerx 300 Watt Solar Charge Controller - Super Compact Budget MPPT Controller!

In this video I discuss the Powerwerx MPPT-300-14.6 solar charge controller. This controller is small and compact yet still packs quite a punch due to it's 300 watt charging limit! It's super affordable costing around $50 or less. They also offer the MPPT-150-14.6 controller for a little less money if you don't need so much power!

You can learn more about the PowerWerx MPPT charger HERE:

I love mine. I paired with with a harbor freight 4x 25w amorphous panel kit. I did find with these panels that unless they are getting **peak** sun they don’t put out enough voltage in a 1s4p configuration (as you noted). With their OCV of 22v per panel I permanently attached a pair of panels together and wired them in series. I can now do 2s1p or 2s2p depending on my needs. Great little controller for Ham field operations

We were just talking about that charger in the emails.
Thanks for the advice.
I can't wait to use this charger but it will be in the spring.

As always, awesome video good sir!!! Very informative and straight to the point

Hi. 14.6 volts may be too high for some inverters with a limit of 15 volts. I'm setting up a new system for a corner of my house that is not covered by my transfer switch running off of my AC 200 Max. What I found is that I had to adjust the Bouge RV 30 amp PWM controller I'm using down from 14.6 to 14.2 volts to keep the inverter from shutting down due to over voltage. I'd come home every evening and find my router light flashing and not knowing why until I stayed home the other day. When the battery gets topped off and the boost charge or whatever it is kicks in and shoots up the voltage from high 13s or low 14s to 14.6, it's too much for the 15 volt limit of the inverter. Even 14.3 was too high. Over voltage is supposed to be adjustable to 16 volts on the inverter, but that did not work. The commentor with the diode idea had something.

Hi Jason, I have a question I purchased the newair 80 qt fridge, I seen that short video you did using this charge controller and a 50ah battery camping set up!
I bought a redodo 100ah mini, I have a bluetti pv120s solar panel 24v open current voltage if I use this charge controller can I wire direct into the battery and connect my Newair 80qt directly just wondering if the wires in and out touch and it's more than 12v will it damage the fridge ? Or does this charge controller regulate it down to 12 volts ? Hope this make sense ! Thank you all you do !

I`m commenting for the AL-GORE-RHYTHM. I bought a buck converter that looks similar that can reduce the volts from a solar panel to 12 volts for experiments. After I get moved I`ll likely get electrocuted messing with this stuff. Got a nice jolt from a 100 watt panel standing barefoot on wet grass awhile back.

My trailer has a 12 volt system and if I switch to LiFePO4 I`ll have to change some things. When I bought it I noticed a cassette player built in to the wall but they haven`t moved it here yet. It looked very nice for the price compared to similar ones costing 10 times more so I immediately bought it and talked them down some. Hopefully the wiring hasn`t been exposed to rats. I needed a place to live and it was that or nothing.

I have some incredible Powerwerks PW-50 powered PA speakers for doing live guitar/singing gigs. Got them for 100 each and can`t believe the quality. I added a Yamaha subwoofer for bass. They`re tiny but plenty loud enough to use for a solo gig in a medium sized club or outdoor event for several hundred people. A small power station can run them anywhere.

I liked your review. What I would like to see though is the amps/volts going in and the amps/volts going out at the same time. That would tell me if its switching or linear and the efficiency of it. I just read on some and found the answers. It is switching and very efficient. I would stop charging at max 14.4 volts instead. I would put a large diode between it and the battery to drop at least .5 volts and no back-feed.

[davidpatrick]

Good one. I am changing over to iron as best I can. I wonder if a dc to dc voltage converter OUT of the panel might work to bring voltage us to the 17.5 (in this case) into the controller … I am hoping to test the 50w sunpower panels. up to a handful which the controller sounds able. have a great day. .

[zodaguado]

What is the brand and name of the dc charger, power supply you said it was 24v 15 amp… thanks

[gojeffgordon]

Nice, just wish it could work at a lower voltage. Still a good install and pretty much forget. No settings to worry about or button to get pressed by accident.

[stallrod]

Could you put a meter on input and output so you can calculate its efficiency?

[trevorbelmont]

Isnt that Watt meter you use limited to 50v? I think I have the same meter but the box say limit to 50v

[AskIveSolar]

I haven't finished watching but very interesting device. Bout to finish up in the minute. So one a lifepo4 battery from amazon and charge it from solar?

OAN, Im always interested in connecting a battery directly to a power station to extend its run time by pumpin in that 100 watt using a 12v cig lighter to bare wire and connect directly to a battery.

I'm in the process is putting together a portable power supply. I have a 100ah lithium iron phosphate battery and a 1000w inverter I'm planning to use. I also currently have a 100w solar panel and was thinking about getting another to add to it. Would this charge controller work for this application? Also, I was trying to figure a way to use 110v house current as an alternative means of charging it, and had been wondering about using a 110v DC power supply for this purpose. Would one like the 24v one in the video be viable for this (safe/effective, etc.)? I wouldn't be using both solar and 110 at the same time. Just either/or.

[DavidFulkerson-py]

How do you know when the battery is fully charged? Most of my lifepo4 DC to DC chargers has a red and green light when charging and charged. This doesn’t do that.

[dezzle]

Great review! Would this be an upgrade to a 20A Renogy PWM controller? I want to go MPPT but don’t want the extra size/cost. Only using a 100w panel on a van so I would go with the 160w version of the controller.

[budmartin]

Good video. I like the small size of the MPPT. BTW, @1:49 Isn't that the charging current ( 9.72Achrg * 13.79Vbat = 134W) to the batteries, not the current feeding from the panel to the MPPT?

[RiddleCrafterExpress]

Is it okay to use MPPT to charge through power stations?
Thank you for this!

[Saleh.Al-Ghamdi]

Question: connecting the Solar Panels to a Portable power station like Jackery (is better?) OR (better) to connect to external MMPT like this then send it to the Power station?

[AskIveSolar]

OAN, did you see Solar Wills video about running stuff directly off solar. I would love to try something like that and the buck / boost converter looks just like this one.
