PowMr MPPT Solar Charge Controller 60 amp 48V 36V 24V 12V Auto - Max 160VDC Input, LCD Backlight Solar Charge Controller for Vented Sealed Gel NiCd Lithium Battery【Software Update Version】

The only problem I found with this is it seems like the directions are extremely hard to understand what I did was go on YouTube and find videos that other people made about this how to program it what to press and that was a hundred times better than those crazy directions this came with although I must give this unit five stars this works very well it did not overheat like most of them do the wires did not get hot like some of the charge controllers do I am very impressed that this thing has a built-in fan that when it does get hot the fan comes on and cools it right down I must have bought 10 or 15 of these from different manufacturers about four of them that I purchased from different manufacturers work very well then I saw this one this has got to be the best one yet many of those cheap things overheat and the wires get extremely hot and you end up returning them I am so impressed with this one I am going to order a second one for a backup down the road if something should happen to this one this is very well built it has quite a bit of weight to it I like the fact that it's in a metal case instead of plastic somebody has a review on one of these and a thing burned up the only thing I could imagine that might cause that is if the fuse blows from the charge controller to the batteries that would leave solar alone coming into this which would probably take it out always be sure to hook up the battery first then the solar again the unit is very well made for the price I also would like to say I have 600 watts going into this 600 w solar panels even on a very sunny hot day the wires going into it only get warm I also like the fact that this displays how many amps you have coming in at the time of bright sunlight it also tells you the exact wattage that is coming into the system some of the cheap plastic chargers would have burned up although they say they are rated for 80 to 100 amps that is not always true also look online some people have posted pictures of the inside of this thing it is very well built with big heat sinks I suggest you not take just my word for it but look at the reviews on this incredible I really think the manufacturer of this has really done their homework I am very happy to finally find a charge controller that works extremely well for this really good price

For the price, a solid choice for a charge controller. Purchased to stabilize a solar-powered water well pump that a previous owner had... not treated well, shall we say. Connected to a 48v series-string of deep cycle lead-acid batteries, charing off of 2 330w solar panels (in series). Yes, the documentation could use work, but is roughly comprehensible with the application of high-school level knowledge of electronics and electrical theory. Durable enough to put "in the field" in a semi-protected environment, and cheap enough to replace outright if it fails due to neglect or hard use. (I'm picking up one as a "shelf spare" shortly in anticipation of that eventuality. No regrets buying it. Does what I need, no fuss, no muss.

I've been using the PowMR 60 Amp for about a week. I'm still working on the panel wiring configuration to get the best results. I now have 4 250 watt panels wired in. The charger seems to be working fine. My only real issue with the charger is the size of the wires it accepts. To be fair, it is described fairly accurately in the product description. I am running 8 AWG pure copper solar wires to my panels, and 8 AWG does not fit. I had to trim a few of the wires off the bundle to get them to insert. The largest wires this unit will accept is 10 AWG. When I rewire it, I will use two 10 AWG to my DC circuit breaker, about 6 inches away from the controller, and do the same for the battery. Other than that, I don't have any issues with the controller. It seems to be working well. Update 3 16 2026. I have been using three of these units for about 3 years now, all have worked well. I had a 24V system, so could only run 1500 watts of panels. So, for my 4500 watt system, I needed 3. I have now switched to a 48v system, so could double them up, but I like the multiple chargers because my panels may be in different shade areas, and I get better performance. I just added another 1500 watts of panels, so added a 4th controller today. I've been pleased with the results of the solar charge controller

Edit 8/2/22: I now have three of these charge controller units hooked up in my system. Again, as with the first two, my third unit came with all of the settings preconfigured for AGM/Lead Acid EXCEPT the last setting which tells the unit to actually apply those AGM/lead acid settings. The last setting on my newest controller, as with my first two controllers was set to "1" which tells the unit to ignore all the AMG/lead acid settings and apply lithium charging parameters instead(which will charge your AGM/LA batteries at 15+ volts and boil them dry in no time). So read the instruction manual carefully and change that last setting from a "1" to a "0" if you are running some version of lead acid and not lithium. The instructions are pretty well written for this kind of Chinese made product. They are also accurate EXCEPT when it tells you that the controller unit has been pre-configured from the factory for AGM batteries. None of mine were. As far as the function of the controller units, they work fairly well. Mine are hooked in parallel to a 700ah bank of AGM batteries. The seller claims that a max of 6 of these units can be hooked in parallel to the same bank of batteries. These units must be installed in a dry location that is protected from the elements. They are not even a little bit water or dust resistant. Most of the parameters are user adjustable, such as the last two charging modes(I dont think bulk mode is adjustable), the disconnect and reconnect voltage (if you wire something to the load terminals) and so on. There are no timer options for the load terminals. They are basically an always on 12v power supply. I suppose you could hook a timer up to the load terminals and the load to the timer. I dont know how adjustable the voltage is for charging lithium batteries since Im not rich enough to afford those. In the early days of these units, some folk complained about prematurely failing fans. Since then, the seller claims that the fans have been upgraded in quality and no longer fail prematurely. My first unit is from the "early days" and hasnt had any fan troubles but all my units are well ventilated so their fans dont come on very often. Neither do I worry much about failing fans in these units since the fans are widely available, cheap, and are so very easy to change out. Another(minor?) issue with these units is that the "press pad" buttons on their interface can require a pretty firm press to work. This can be mildly annoying for those of us who frequently like to monitor the readings of our systems. Also, after you change parameters, you are supposed to shut the unit down and then turn it back on and make sure the new parameters took. Sometimes they dont. It took me 4 times to get the low voltage cut off set in my newest unit-which is kind of silly in the first place since I dont even use the load terminals on the controller. Another issue is that all three of my units show a different voltage reading for my battery bank. For example, unit one will show 13.2v, unit two 13.3v and unit three 13.4 volts. I get an accurate reading from a phone app that monitors my inverter so its not a big a deal for me but the discrepancies do make me wonder how accurate some of the other readings are that Im getting from the controller. My final complaint about these controllers is one that I suspect I might experience with any group of controllers hooked in parallel to the same bank of batteries; They all seem to like to do their own thing, regardless of what the others are doing. So, controller three could be in mode 8(float charge) while controller one and two are in mode 7 or mode 4 or whatever. Since the charge state of the batteries dictates which charge mode the controller is in, perhaps the slight discrepancies in the voltage readings between the three controllers is the culprit here? Or perhaps one controller is reading input from another controller as the charge state of the batteries so thinks the batteries are fully charged-or not-when the opposite is true? Not that it matters, I suppose. If you think about it, the system would balance out and charge up just fine even in the case of one of the scenarios that I just mentioned. Also, like I said, I think this issue would pop up in any system where multiple controllers are hooked up in parallel to one battery bank. I think that I should also mention that these controllers do not come with temperature probes and have no place to hook one up. They do have a built-in environmental temp monitor(measures surrounding air temp) but I am dubious of its accuracy. Two of my units are mounted side by side with just 3 or 4 inches between them and the temps they show are never even close to the same. I have yet to compare their readings with a proper thermometer to see which, if either of them is accurate but plan to at some point in the near future. So! Bottom line is that these chargers arent fancy but they do the job pretty well. They are inexpensive, keep my batteries safely charged once properly configured, and are durable. Ive been running one of them for three or four years now, the second for over a year and third for just a month. These controllers automatically recognize whether they are hooked to a 12v system or a 24v system so will be useful when I eventually convert my12v system to 24v. At 24 volts, Ill be able to hook twice the number of my current panels to each controller which will give me a whole lot more room for expansion without having to purchase more controllers. This is the 2nd Powmr 60 amp mppt controller Ive purchased. The 1st one I bought over 3 years ago and is still in use. Ive recently increased my solar array beyond what just one 60 amp controller is rated for so needed a second controller. Since the 1st Powmr controller has worked well for me, naturally, I did not hesitate to buy another. I have only one complaint about these controllers and its a pretty significant complaint, especially for folk who are new to solar stuff and battery settings. Youre told everywhere; in the instruction manual, and even here in the product listing that the controller comes preconfigured for AGM/sealed batteries. This is NOT technically true! It actually comes preconfigured to lithium batteries but this fact is not easy to discern. Why? Because as you scroll through the settings on the controller screen, they do "appear" to be configured for sealed lead acid batteries. Then you reach the last screen and see a code "1" setting. What is a code 1, you ask? A code 1 over rides all other settings to apply lithium charge parameters to your batteries. So all those nice, sealed lead acid settings you saw leading up to the "code 1" screen? Theyre just pretty numbers that mean nothing. Not as long as that last setting is a "1". You must change that to code "1" to a "0" for the previous lead acid settings to take effect. I discovered this with my 1st controller by noticing that my controller was often charging my batteries at 15+ volts and making them boil!! I quickly investigated and discovered the issue. Changed the code "1" to a "0", reset the controller by un-powering and re-powering it and Ive had no problems since. My 1st controller now charges my AGM batteries exactly as its supposed to. Ive had no problems with my 2nd controller because the 1st thing I did while installing it was fix the code 1 to a code 0. So these are great controllers and you gotta love the price! Just know that they are NOT going to take good care of your sealed lead acid batteries out of the box as is claimed by the seller! You must configure that code 1 setting to a code 0 or the controller will try to charge your lead acids as if they are lithiums. And that aint good!

I was excited to start using this as many reviews gave it good ratings. After install, I was not getting as much current to the batteries as expected, so I decided to setup some quick switch networks so I can quickly compare between this MPPT controller and my existing PWM controller. Guess what, my PWM delivers about 50% more current to the batteries than this piece of JUNK! Details if you want to understand more: Unboxing: During the unboxing stage, I notice that there is some blue protective film wrapping the controller. The bottom right corner had been peeled back a few inches. There were a couple of scratches on the lower controller. I noticed a depression in the housing in the upper left side where the mounting bracket attaches. My initial thought was that this might not be new, or maybe it was reworked in the factory, or was simply mishandled. I decided to try it anyway. After removing the blue protective film, this also removed the model sticker. Instead of placing this label on the actual metal housing, it was place on the protective film. Maybe someone was in a hurry? Or maybe they expect you to run this with the film left applied? Not a good first impression. Initial Setup: The manual is actually written fairly well for this type of item. Still, there are errors in the manual. (For example, Fan on/off temperature conversions between F/C are not correct.) In the manual, Installation section, it clearly shows step 1, connect battery, step 2, connect the solar panel, etc. I read the entire manual before actually making connections. If I had not, then I might have connected the panels without configuring the MPPT settings. Later in the manual it says to make these settings for absorption and float voltages while the battery is connected, but panel is not connected. I think a simple statement here to the fact that a configuration is needed would be a nice addition. Under the Operation section in the manual, I found that a bit small to read. It took me a while to understand what that diagram was trying to tell me, but it was obvious after I actually went through the controller settings. Under Manual Setting, this is where you can configure the controller to your preferences. D00 is for setting the load on time. I do not use this, so I left it set to 24 hours. D01 is for setting the float voltage (according to the manual). My controller had this set to 14.5V Ouch! D02 is for setting the absorption voltage (according to the manual.) My controller had this set to 13.8V. D01 and D02 are in conflict between the manual and the default controller setting. Which is correct??? D03 is for setting the low voltage shutoff. I do not use this and left it set to 10V D04 is for battery type configuration. Manual states 0 is for lead acid and 1 is for Lithium. The Amazon description states that this is configured for lead acid (0) but mine was set for Lithium (1) as many others have commented in the reviews. The settings are completed now. I removed battery voltage and reapplied to verify that the settings remain. They did remain. Now I connected the panels. My panel and battery configuration: I have 5 12V panels with series diodes for backfeed prevention. The cathodes of those diodes are all connected together and goes to the Battery+ on the charge controller. The Negatives from the panels are all tied together and they go to the Battery - on the charge controller. I chose diodes as to keep any panel backfeeding from happening due to shading, or controller malfunction. It works well on my PWM setup. I have switches setup so that I can quickly move battery and panels from one controller to the other. I have made many observations at different sun levels and different battery voltage levels. I have 12V batteries connected to the charge controller. (The new capacity rating for all three parallel 12V connected batteries is about 90Ah, but due to aging, I estimate it is closer to 30Ah.) I have tested in non-direct sun and find that my PWM controller is providing 0.49A to the batteries (Battery voltage is about 12.3V). If I switch to the MPPT controller, I only see about 0.39A to the batteries. Due to the smoke and other haze in the air this week, I am not getting peak performance from my panels, however at the expected peak performance (time of day) I measured 70Watts being delivered to my batteries (batt voltage around 12.8V) with this MPPT controller. I switched back to the PWM controller and I get 110W. I have done this probably 12 times and EVERY time I get the same result. I ALWAYS get much better current from my PWM as I do this MPPT controller. I verified the settings with the manual and it seems to be set correctly. I contacted the supplier. Although they have very prompt response time, their response was disappointing and not helpful in any way. The only conclusion I can draw at this time is that either this item is defective, or, the design really can't meet the specifications implied or stated by this controller. I have no use for this controller and will be returning it as I am within Amazon's return window. I am deeply disappointed that this did not work out for me. Many other reviewers have stated that their controllers work well, but I don't think any of them have made actual electrical measurements or comparisons that I have done. I could take this much farther, but due to not wanting to spend time on what I consider to be JUNK, and working toward a fast approaching return window, I opted to stop my testing here. It is pointless to continue. I hope that anyone that is seriously considering a purchase of this item will do their own electrical verification to see that what power is being delivered to the batteries actually makes sense. It is not hard to do with a simple Volt and Current Meter. I have dedicated power meters setup before and after the charge controller so I can see what is happening, but simple DVMs can work for lower currents. But, be careful of the max current that your current meter can handle. More than 10Amps might be bad for the meter. Bottom line is: Do you own verification and see that this really works for you. Don't just say, oh, it runs my television or my computer. That really does not say anything meaningful. Conclusion: While this controller does work about 50% of what it should, you could save a lot of money and just buy a simple PWM controller. Or, maybe another MPPT controller actually works as it should. I will be on the lookout for a better controller. My conclusion is that this is JUNK and that you should not buy it. There is a chance that I just have a defective controller, however the replies with the supplier were not helpful and never suggested a replacement. I suspect that the design is just not capable of what it claims and I will not waste any more time trying to get it to work. If you do purchase, please do your own verification.

Este producto es muy bueno. Llego relativamente rápido. Gracias

PowMr 60 Amp Review. A True MPPT solar charger is rated max at 48v battery ( Lithium self defined voltages ) at 2,800w Max Solar Array & 150 Voc. Manual is ok English. Stacking batteries in series to raise voltage from 12v to 24v/36v/48v in the solar charger user interface for voltage charge settings will take some math to calculate if you use Lithium! You must always use a multimeter to ensure accuracy! Danger Unit does not shut down with high temperatures. Its does have reverse polarity protection. Very light weight and minimal internal components. All wattage is posted in the Manual. This max PV ( solar Panel ) wattage is to prevent you from going over 60 amps and frying the unit! It does have the thick aluminum heat sink inside but No cooling fins and must use a spacer between unit and wall mounting to allow for air flow behind the charger. The mounting taps or the screws given to use to mount the unit are not correct. Screws fall out. Simple fix at a hardware store. Over view. Light weight, simple component build, dual plus & minus for 10 gauge wire for both PV and battery ( always use dual wire copper braided, Its DC not AC ). PV ++ -- and Battery ++ -- this is a total of 8 Ten Gauge wires total required for proper operation. Reversing the fan inside to blow in cool air boosts direct board and component cooling. Lowering the # of series panels VOC will also keep the unit cooler in operation as the Mppt crushes down voltage to meet the battery voltage. Star rating 1of 5. General quality durability 3.5, easy to use operation 3, Mounting design 2.5, internal design 3, Potential fault safety 4.5, Heat dissipation 3.5, Manual English translation 4, Product value for cash tender 4, Satisfaction 3.9 Would I buy this again? Sure great economy value for what it is! A true Light weight Mppt budget friendly solar charger. Notes: Use a lower Voc to keep cool. Use dual 10 gauge braided copper wires for efficiency 93% conversion <- nice! Reverse fan to help cool. Certified schematic Clone. User interface requires a steep learning curve as the information and values are a bit hard to understand. Noisy cheap fan runs at 100% when cooling and is loud! think hair dry on medium speed loud. Up date 8/29/2024 Cleaned fan every 3 months to prevent dust build up. The tracking still jumps wild as my 48 v systems PV array is a stable 94volts. The controller is programmed to restart every 15 seconds or something and retracks. It should stay stable at 94v and 1,600 watts inc on a cloudless day. It has retracked down to 54 volts all the way up to 129 volts then settles down again for another 15 seconds. This to me means there is significant amp charging loss as it re finds itself over and over. To me this means the unit is working properly 66% of the day while wasting 33% of the day tracking and causing power loss. If this clone of Make Sky Blue has a firmware update i'm sure this tracking issue wouldn't be a problem. 3 out 5 stars. This puts the unit at a minimal off 66% efficiency. It does work and charge when its stable.

When I got this, I plugged everything in, set it up for my Lithium batteries then wired it up to the panels. The holes for the wires are pretty small for the larger gauge wires, but I got it hooked up..... Then it kept overheating, and it's safety feature shutting it off. I contacted support at their website, and was answered within 8 hours; they are VERY helpful, and were pleased to offer me a full refund, giving me till Jan to do the return. Well, it turned out I needed to split my larger gauge wires, and put each wire into both holes for each connection, as you can see in the photo, and instead of the breaker switch I had been using (60 Amp), I got 150 Amp breaker to relieve any traffic jams going on there, to keep that wire cooler. Also, pay no mind to my battery connection wire colors leading into the controller. They are reversed: red is black (negative), and the black is red (positive) as they were the only wires I had left it the right lengths to safely hook it up.... AND the digits showing on the window are low, because the sun is barely starting to rise above the horizon right now, so no charge going on yet. Now, since I split the wires in the hook-up process, it is working like a dream. YES, I am VERY HAPPY with this charge controller. YES, I HIGHLY recommend this unit to others. YES, POWMR has proven themselves to me, as makers of good products, and EXTREMELY GOOD CUSTOMER SUPPORT! Thanks, PowMr folks, for a great product that has helped me to upgrade my system, where i could never have afforded to with the other prices.

The first showing read screen always showing 0's. Bat & Sun. Why?. Next screen is True Bat. read but Sun 0. WHY? 3rd. Shows true Sun read as can watch read change as sun strength do. But battery on this Screen read is Always3. again why not TRUE Battery Voltage?. The 4th screen have no Idea what that Read IS. as shows a fig. 18, this figure can't be changed in anyway. WHAT THE DEVIL IS THIS READINGF? Before Taking this reading connected strictly to instructions to load itself 1st before attempting next Steps. Another, can't understand is that after Sun Down WHY IS THERE A DOUBLE DIGIT No. still showing? thought should be NERO as Sola Panels wouldn't be producing power @ all. Please somebody Explain to me as actually does seem to be Charging from the Panels. Hard to follow with such confusing readings. Regards, Murray DAY
