POWLAND 100A MPPT Solar Charge Controller,12V/24V/36V/48V Auto,Max Input 150V LCD Display Regulator Intelligent Regulator Charge Controller

I have 10 older solar panels that I bought used. I have been using various cheaper charge controllers that were either pwm or that claim to be mppt and worked pretty well but were not true mppt. I have a hard time spending money but I finally spent a little more for this one. I am thrilled. We finally have a little bit of consistency with our solar output. Most of the day my batteries are full and my four lithium batteries even had enough juice in them to weather most of about 4 or 5 very rainy, post gulf hurricane days in northeast Arkansas. It says it has a one year warranty I believe. I hope we don't have to test that. The product manual is pretty straightforward and easy to understand. I am pleased with this purchase.

The media could not be loaded. This controller is better than I knew it would be. Very simple to set up and has great features. My favorite feature is it tells me my battery percentage and how many amps are going out and watts. The instruction manual was very easy to follow to set this up for my lithium ion batteries. For the price you cannot beat this and highly recommend this controller for all RVers or off grid people

I have been using this controller to charge an 800ah bank of batteries all summer long to run a 5000-btu window AC unit. And it has done a Fantastic job in keeping my new batteries in peak condition. Seems to be very efficient. In fact it outperforms many high dollar units. Sadly I have had to mount it in a very Hot closet. Texas summers are that way. I would rate it 5 Stars except the cooling fan runs an awful lot. Every few minutes during the day. That said, in my 20+ years of solar off grid experience, when the fans on these things run that much, they tend to Not last very long. But, it is probably the best charge controller I have owned. I waited until the end of summer to write a review because I didn't think it was going to last. That said I bought two, one as a backup, which I have not used. I Read the reviews before I buy ANYTHING, and there was very little on this one when I bought it. But so far it has been an outstanding charge controller. And it performs according to specs. Very solid.

I had it for about a month. It was good, then it produced less amps. It also stopped charging the batteries before it was full. There are 2 more reviews here stating it stop charging before a full battery. Seller tells me to check externals like wires and sunlight. They're the same, nothing changed except for the mppt. Seller refused to honor warranty and replace.

Received the 100 amp charge controller yesterday! Quick shipping, packaged well and was easy to hook up. The user manual is VERY well done! Easy to read and has a COMPLETE setup and operational steps. The GREATEST part was to find that this controller actually WORKS and is much more efficient than other "lower priced" ones l've used!!! Kudos to the manufacturer and seller of this product! I will post more after it's been installed for a month or so!!!

I hate to complain because this really is a very nice controller. Apparently someone who puts them together is a little heavy handed. I bought one previously from Ebay, and had some problems getting the cover off where I load the wires, but finally got it. NOW today I get this one from Amazon, same controller and at this point and after going to the shop for 3 different screw drivers, I CANNOT FOR THE LIFE OF ME GET THE LITTLE SCREWS OUT THAT HOLD THAT PLATE ON. Someone must have thought they were working on a car engine and TORQUED the screws at like 80 pounds. Not feeling good today so did not need this. No doubt I'll get them out somehow.
