Renogy Voyager 20A 12V/24V PWM Waterproof Solar Charge Controller w/ LCD Display for AGM, Gel, Flooded and Lithium Battery, Used in RVs, Trailers, Boats, Yachts, Voyager 20A

I have an IRLP node with a 12V lithium battery for backup should the power go out and I needed a charge controller as the DC in I have is about 20V, which is naturally too high to simply directly connect. This controller is exactly what I needed. It will do SLA, flooded and lithium chemistries, you need to select type of battery manually, and you can dial in what charge voltage you want, in my case, according to the battery I have connected, it wants to see 14.4V. You can set up the LCD readout to display what you want for the most part and it has performed flawlessly since I have had it. The instructions are fairly clear on what you need to do to set it up and it actually is pretty easy. It has worked well during outages, switching from the input source to the battery is seamless. I am very happy with this controller and have already recommended this brand to my friends that were looking for one for their various reasons.

Without a doubt and after testing most of the PWM controllers in this realm, I'll say this one is the best. This one not only works, but you don't have to worry about it and it just works. It's also a great price for 17$ which is what I paid. If you are looking for a charge controller either for a backup or just because you have less than a 200w panel or two 100w panels in parallel this little controller will fit the bill for you. You can add the BT controller if you want but why? That costs more than this unit and this unit already has this data built in. Just press the select button to see voltage, amps, battery voltage, load, load settings and ways to maximize your small setup with a excellent PWM controller. Thank you Renogy for this controller and please keep this low price for all of us that know how to properly use this. This is seriously the best sub 20$ PWM controller out there for small panels and it just works with all the features it provides. I'm very happy with this unit and would highly recommend to anyone.

To avoid confusion, this references the Renogy 10 Amp 12V/24V PWM Negative Ground Solar Charge Controller Compact Design w/LCD Display. Renogy seems to be among the leaders in our ever-growing world of solar technology. I have two of the cheap (under $10) PWM controllers, and they work okay, but for the price, I happily upgraded to the Renogy controller. Briefly: Pros: Economical. Will connect to a Renogy BT module (sold separately) Tells me most of what I need to know in its LCD menu. They do have customer service ( but reviews of this are mixed. ) Cons: Terminals seem to be designed for wire 12 AWG and smaller. I got 10 AWG in there, but I won't trust them to stay. A reminder, PWM is not the best type of charge controller, but if your needs are modest and you have no shade to interfere with your solar energy collection, it works pretty well. This 10 amp controller is good for your basic needs, handling up to two, 100-watt panels in parallel (series might be right at the limit). It works with all the major battery types, but you need to manually set Lithium types. If you want or need a more sophisticated solar energy setup for your home or large RV, you will likely want the much more expensive offerings from Renogy, Victron, and others. But for an older teardrop or backyard project, this is quite adequate. When I'm done playing around with it, I plan to affix it to one of my Renogy 100-watt suitcase solar panels. Need cheap and simple? Buy it. Happy solar, all!

Finally, a controller that doesn't lie about being MPPT. This is PWM and appears to work well with my radio room backup ex-car battery. As others have said, the connections for the wire will take a realistic gauge for light solar work - #12 in my case. Instx for setup are plain enough. The readout rotates between incoming solar panel voltage, current from the panels going to the battery, battery charge voltage, current used by the "load" output, and error [or OK] code. I'd like to have seen this pass the full 10A it's rated for out of the "load" teeminals. For a garage or patio/pool lighting scenario, I'm sure it's fine. Turn on a VHF/UHF two-way radio, and the filter caps must confuse this charger's amp measurement as it goes into a protection mode. Not a problem in practice; I'll just keep running the radios off of the battery/AC-DC supply/solar cintroller feed all paralleled, per normal. All in all, a very fair deal for the money.

Works correctly.

No complaints at all so far. Plugged a 160W Kings Folding panel into it, and in late afternoon, Winter sun on the east coast of Australia, angled towards the sun the best I could, I was pulling 7.85A out of this controller which is more than enough to keep my fridge running indefinitely off my lithium battery. Don't let people tell you that an MPPT is superior, because for small panels, there's very little difference in my experience. Excellent controller that I bought as a backup in case my CTEK blows an internal fuse (again) and is totally useless. Build quality is good, hard plastic with an aluminium base plate. The grub screws hold 8AWG cable very well and it won't pull out on their own easily. The LED indicators are very bright and easy to see in sunlight too.

I may have gotten a Friday afternoon item, you know , one of those things that were not quite finished off properly because the finishing hooter went off and the production line shut down and my unit was stuck in a box untested. Unfortunately it didn't support Lithium batteries, it said that it did in the advert, it said that it did on the Renogy webpages, but it didn't say that on the LCD display or on page 13 of the manual that came in the box with the unit. I contacted Renogy and after an hour of sending photos of my unit, serial number, receipt and explaining the situation it was suggested that I contact Amazon and ask them to sort it out. Anyway, they were as useful as a chocolate fireguard. Amazon, on the other hand, refunded me. So, now I am going to order a cheap mickey mouse controller, like the one in my shed's solar system, no branding, cheap as chips but it works. So much for going with a branded big name product. When I ran the Wanderer I couldn't even get more that 3,45v out of the load terminals, weird.... panel was producing 34v dc, battery 13.8v and load terminals 3.45v. Good luck with yours.

Los equipos Renogy funcionan sin problemas, son fáciles de configurar y seleccionar el tipo de batería a utilizar, la identificación automática del voltaje es otro punto a su favor

Cumple con lo que promete, Trabaja de forma correcta.
