I've been a subscriber for about 6 months now. I decided to go back to your day one video and start my Slim Potato head marathon. I truly appreciate you going through all the trials and tribulations of solar for boondocking. You have taken the chances that we probably wouldn't have done. You've explained everything very thoroughly and given a bit of humor to boot. The information you have provided is invaluable. Maybe one day we will pass on the road. Thank you for your insights!

i am not a camper - skuze me, traveler - but a boater, and I always pull up to a marina that has shorepower. My idea of "roughing it" is a Super 8 motel. So, my boat has a 7.5 kw generator to run 28 k of ac/heat. That said, I really enjoy your extremely practical solutions, that keep you in budget, but also work. This video is the best so far. Technical, but simple. Thanks you so much for showing and explaining in detail how a solor panel works, and the difference it makes to have two or more in series or parallel. Just like Christmas tree lights! I hate those lights in series... never know which bulb is bad. Obviously, after your fine instruction, the same thing goes for solar, although not nearly as much testing required to see which bulb went bad. But just the fact that when in series and the whole system shut down, would be enough for me to say that parallel is a no-brainer. If it were raining for two days in a row, I surely wouldn't want to have to get outside to test and repair/replace one of the panels. I know, I know... if it were raining two days in a row, then nothing would work, anyway. But you know what I mean. Thanks much, again. Keep it up. I try to watch most of everything you do, and always give you a thumbs up.

MPPT is the way to go Slim. I am full solar power at my home and have the old PWM system and the new MPPT system. Functions as advertised. I look forward to your postings every week. Would love to be doing what you are doing. It will come, someday. Safe travels to you and if you are ever in WEST VIRGINIA stop in and camp on my land for free. I think you will like it. ALMOST HEAVEN WV

@Jeff2006lee 5 лет назад

I am electronic tech from USN 30+yrs. I appreciate your comments and it was good see your blunt illustration of plugging your panels in serial verse parallel. I have solar panels in the windows of my town home. I believe I have them all plugged in serially as the MPPT can take in higher voltage & higher voltage is more efficient. Noticing your panels shut down all together if one were blocked by little shade, well I do have problem of shade. So thank you for your great common sense illustration. Jeff

MPPT controllers are efficient but very noisy radio-wise. I had an MPPT controller on my last RV, it created havoc on AM (MW) shortwave (SW), ham radio bands and wiped out most VHF including the 162 MHz Weather Band even after shielding and ferrite chokes on the leads.. So be cautious if you are a ham, CB'er or listen to AM or SW. Thanks Slim.

Slim, this was a very good simple explanation of your system. Thank you. I now have a much better idea of the differences in functions of Parallel and Series work. I know that in many of other videos I've seen about the MPPT controller people have chosen, few understand its technology. But, its increased and enhanced performance cannot be denied.

@marksommers6764 5 лет назад

Within the last 10 months I I've replaced two controllers with MPPT units . (Xantrex with external resistors and a much smaller Generic unit) ALL of the lesser units gave poor performance and even ruined batteries (accumulators) ! I'm having WONDERFUL results with MUCH better "depth of charge" ! I've two 220 watt 12v panels in parallel and two 8-D flooded lead-acid batteries @525 AH each in parallel . I had gone through a few lesser controls....all bad . Happy trails , Slim !

@fratermus5502 5 лет назад

The epever/epsolar/tracer units are solid.

@geraldhenrickson7472 5 лет назад

There are some fine PWM controllers still available these days yet due to their incredible reliablity, are very expensive and used mainly for lighthouses, road signs and street lights. Most of us are better served by MPPT controllers.

@thizizliz 5 лет назад

Ahh, interesting. It makes good sense to think about what works when 1 panel isn't at 100%. Looks like the extra size of the controller didn't lose you much space either. It will be interesting to learn along with you as you travel. Cool.

@TheSeanBampton 5 лет назад

Straight forward and simple to understand. Great video, Slim. Thanks for this one. I'm going to be buying a ETFE panel to replace my 90W Canadian Tire special with the 7W charge controller.

@SlimPotatohead 5 лет назад

Sorry but Canadian Tire make the worst overpriced and outdated types of panels. Stick to Amazon. SP

@TheSeanBampton 5 лет назад

@@SlimPotatohead No need to apologize Slim. I bought the panel many moons ago, before I really knew anything about solar (and before watching your channel). It's served it's purpose, but it's time to get real with our needs, as we transition from a tiny popup trailer with a single 12v battery to a Lance 1575 where I'll be installing 4x6V LiOn batteries in series. Looking at buying 4x100W panels and running them through a 40A MPPT controller and into a 2000W pure sine wave inverter. Like you, we are often boondocking, at the provincial campgrounds or wilderness sites in BC. Happy camping!

@dona62851 5 лет назад

@seminolerick6845 5 лет назад

Nice job... Good Luck 👍

@AlGritzmacher 5 лет назад

Love it. I would have done exactly the same thing with the controller. You'll never have the heat problems that need the air space around it because you'll probably never be near the 30A rating. I'd have put it right where you did. It's the only logical place, near the battery, near the wiring. Short wiring = less resistance = more efficient!

@ericst-denis9661 5 лет назад

what does it power up or should i say what can it power ....?

@notyoung 5 лет назад

Very practical video and installation. Sold my pop-up camper years ago and my body no longer accepts compromised sleeping locations ;-) Panels in series should have bypass diodes that take them out of the circuit when they can't produce power. That means the shaded panel simply passes the power from the sunlit panel. Your power is cut in half but it doesn't go to zero. Most framed panels have bypass diodes but I've not tested enough flexible panels to be able to make a general statement about whether they do. They should, as it's maybe $0.50 more to build the panel that way. Always good to know which equipment lasts and which doesn't. I have 3 EPEver MPPT controllers: two 3210A and one 4210A (predecessors to the AN model you have). One 3210A has been in continuous service for 2 years. It survived a lightning strike (in the next block) that took out the USB ports on the laptop I use to monitor the various MPPT controllers so I think that bodes well for their survivability.

@dx9s 4 года назад

I searched to see if somebody else made the same observations. YES, many flexible panels don't have blocking (bypass) diodes and thus a panel in shade ends up consuming the power produced by the other panels in series. Important thing to research before purchasing. I have seen a few flexible panels that have diodes in a box for this purpose. The main advantage of series is higher voltage with lower current over longer wires = less loss due to resistance.. As those panels don't have such diodes, hooking in parallel and keeping the wires shorter/thicker is probably the only option. The MPPT has three basic limits 1) the PV input voltage needs to be MORE than about 2V over the battery voltage in order to charge /easier to do with series panels as partially covered cells can sometimes still produce additional power that will not go to wasted in MPPT w/ panels in series [requires diodes tho] 2) maximum "safe" Open Circuit Voltage (usually ~2X the "listed" voltage of the panels) so a limit to the number of panels in series summing the voltage 3) maximum Amps which effects the number of panels in parallel / or any series+parallel wiring for max voltage/amps .. -- MPPT also usually has a max power (watts) as well.

@pederb82 5 лет назад

I’ve had the old version of your tracer for years. Works like a charm. Mine is common negative tho. You tell them apart by the color of the buttons on the controller. Mine are yellow like on the my-50 remote unit while yours are green. Both are great units.

@OliverAllpress 5 лет назад

Thanks for the video! Looking forward to your updates on the solar setup on the road :-)

@blueharley2 5 лет назад

one of your best!!! Thank you. I've not seen another bench-test comparison to show the parallel/series difference. I know that MPPT handles higher voltage, with the main advantage being smaller gauge wire, such as running to remote panels in your backyard. This is not really advantageous for short wire lengths in a camper scenario. I have understood that a series system would still be in charging mode at twilight, but now I see that's only true when all panels have the same light intensity, even in bright sun. That's really informative to see what a shadow does to a series system. Seems like shadows and short line lengths negate the added expense of MPPT.

@moretimethanmoney8611 5 лет назад

I had no idea that shading a series wired system would kill the power through an mppt controller! Excellent info. Thanks!

@fratermus5502 5 лет назад

It's a bit more complicated than that. With enough voltage overhead (say 3 panels in series) MPPT can reduce voltage to bring shaded strings back online and make more power than parallel. With only two low voltage panels I'd run them parallel instead.

@deanmills5106 5 лет назад

Thanks Slim, that was interesting.

@timcomer262 5 лет назад

Dang you Slim Spudhead... I was happy with my ten dollar PWM no-name charge controller, then you had to do this video explanation. Triple dang you! I just ordered the Epever and rearranged my galley to accommodate. Had you NOT published this I would happily be camping away content that I didn't "need" MPPT. So far my 200 watts of panels and 144ah of battery have served me well. I'm anxious to see how this new MPPT will charge faster and keep me from having to haul around any more panels. Time will tell. Keep the videos coming. I'm enjoying your interviews and trip logs.

@timcomer262 5 лет назад

And, I opted to get the bluetooth module instead of the remote meter (MT50). Big mistake, couldn't get it to connect for two days, then when it did connect the app was near useless for my purposes. Shoulda stuck with the same package you bought with the temp sensor and MT50. Returned the bluetooth and ordered the remote meter.
