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 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

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.

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

Works ok. Have 2 327 watt panel. When i first hook it up i was getting around 520watt. Then like a couple of minutes it drop down to 440 watt at most and stayed around 420 to 440 all day. So idk. Well see bout it tomorrow oh and yes. The slot are mainly for 10 awg wire at max. And i can't seem to change the setting at all

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.
