6 month update: It's still working perfectly and my batteries are in great shape. I would definitely recommend this one over the others that I have tried. I have 48v 12s batteries and attempting to find a unit that can handle this is difficult. Most of the units that charge "48v" don't actually charge or have a way of charging 48v but instead are for 13s 52v batteries and with no option to set it up for a 12s battery. This one can do it but it's a little confusing as to how to make it work with a 12s battery or to change the parameters of the user settings for more than a 12v system but it does have the ability to do it. If you are running a 48v system you have to set the user settings for 1/4 of what you want the parameters to be, same goes for a 36v system but 1/3 and a 24v system 1/2. I don't know why they didn't just go the extra mile and let you input the numbers that you want instead of having to do a conversion between 12v and what you system really is but what can I say, I'm not in charge of systems design. Either way, it works. I had to divide all of my settings by 4 and enter them into the user setup and everything was fine. All of the other types of batteries are presets that you just select unless of course you want to keep your battery charged at 80% to extend its life like I do. Then it's off to the user settings. However, they give you all of the parameters for each battery type so you can set it up like they do but at lower numbers so that you can limit your charge if you want to. So far, this thing is perfect but I will do another review in a few months to let you know how it's going. I am expecting good things and for now, it's 5 stars.

Took a week for me to get time to install the unit in my enclosed trailer camper conversion. I have 2 of the Eco brand 100w panels hooked up to it thru a combiner box (adding 4 more 100w panels in the near future). Got it on the 2024 July day sales for $80. I am using 8 gauge copper tinned marine wire to feed my single 80ah 12v deep cycle for now (soon to be 3x 100ah LiPo). Seems to track pretty well thus far. Its not an Outback or Midnite Solar (I have had the later model in my offgrid cabin) unit so don't get super excited on features or amperage. Will update if things change. 8/24/24 Update... Charge Spikes?!? (See spike video in review) (Currently 8/24/24 I have 4x 100w Eco Brand Panels and LiPo 12.8v 100ah Battery) (14.4 charge / 13.6 float settings) I sent PowMr support and email today for the following: I bought a new PowMr 60amp MPPT (Pow-M60-Pro) solar charge controller on July 17th 2024 that delivered on July 23rd from Amazon Order Number 111-0xxxxxx-xxxxxx and its started to have issues in "boost charging mode". It will kick to over 15-17vdc and then reset itself and drop back down to the proper setup of 14.4-14.5 vDC. Like its allowing most the solar panels 19-20 vDC voltage to spike thru. Hopefully they email be back on this issue. Will update if/when the do and resolve.

Muy bueno y robusto en cuanto a su trabajo y una gran cosa a su favor es que tienes la oportunidad de configurar la entrada de voltios desde los paneles por otra parte no permanece con la pantalla iluminada pues baja su intensidad que casi no puedes ver hasta que tocas un botón y vuelve a iluminarme por unos 6 segundos y el sos no parece decirte el porciento real es como si no funcionará solo de adorno pero las demás informaciones si funcionan bien en mi opinión si funciona a su potencia.

So, I bought this a little bit over a year ago. I used this only once on a 2 day trip. Seemed to work just fine then. Second time using it and before my trip, decided to ensure everything is in working order. I switched on the solar panels and the charge controller started up nicely. Was charging my LiFePo4 batteries on the right setting and everything as it did before. The batteries are working and running the controller for 1 day and over night, the charge controller was not charging. It was giving me a nighttime mode symbol on the top left of the screen as if the panels were not producing any power. This was happening all day long. My batteries were dying and the controller was not charging. I decided to disconnect everything and place it directly onto just my panels. My panels were producing 18.6 volts. No problem with them. When i reconnected the panels, the controller turned back on, showed like 14 volts, believe its the voltage its producing for the batteries, but the batteries are not connected, and after about 10 seconds, the controller screen turns off and can see the volts dropping as its turning off. the panels were still producing 18 volts with no fluctuation as i had my multi meter connected to them. The controller, after about 30 seconds, turned back on again. This kept happening over and over. Off then on, then off, then on. I tested the battery output and when it turned off, the battery output produced around 1 to 2 volts when it turned off and back to 14 ish. I am not sure what happened, but after only using it once, twice if you count me testing, it became clear I should invest in a more expensive charge controller in which instructions are clear and the device is not poorly made. Since this is most likely out of warranty, I decided to open up the controller. One HUGE major flaw that the manufacturer should have never done is place a metal plate directly behind all of the terminals where you insert the striped wires in at. It is just one long plate. There is no insulation or barrier to prevent the terminals from shorting each other. Its possible some wires may have moved or became loose and had touched the plate, but am not entirely sure. My stripping is not that long, but is possible due to the manufacturing error. Anyways, I am buying a new charge controller, but not his one again. i plan on testing some components within the controller and maybe replace them if needed as it seems to work, but continuously cycles its power on and off. Worked great for two days, but can't do much about design flaw since the manufacturer decided its best to short the terminals if wires are more than 1/4" striped.

I bought this as an upgrade for the solar system on my boat. The display screen didn't line up with the case, couldn't see half of the screen. Wanted to contact the seller to get it sorted but couldn't find a way to. So I ended up taking the controller apart to fix it before I could install it. Shame really as it seems to be a good piece of kit. Shame it was broken and I could get in touch. I upgraded from one of the little blue controllers that you can find on here for less than 10 pounds. Never had an issue with the cheep ones.

Not many controllers can handle 36v panels on 12v batteries. This unit does and it's sensibly priced. Menu is a little confusing to start, but you eventually figure it out.

This item is not as advertised and setting it is almost impossible
