Ive been using this mppt oae charge controller for 5 months now. I have 4 100ah lifepo4 12v 1280watt per battery . That is 400ah 4800wh. PV solar 2l4x100 watt per pannel = 400 watts 12v @22.3 to 24.3amps in full sunlight. I run about 10 led lighting and a refrigerator as well some power tools occasionally. I have 4 more 100 watt 12v pannels to add to the system. Max PV input is 900watts. It has woeked great no problems other than some fine tunning of charge ans voltage settings witch it gets agroed and beeps. I set it correct and hasn't gave me any attitude since. I wish it was capable of handling 1200 watts @12v dc @60amps charge current for the bank i want to use because i have 2 pure sine 3000watt inverters running in parallel . I like this controller functions well well built sturdy. Will purchase one more double my array with confidence. Recommend it on the reliability ive had with mine. ( going to jump up wattage on second purchase 24 or 48vdc see what it will handle and will update the results.I gave it 4 stars only because of low wattage @12vdc, and noise . Will buy again.

Wonderful so far. Wish I had more batteries for the solar system now

I have 1890 watts of solar power, 3p2s setup, running to one of these chargers, charging 2x 100ah 48v lifepo4 batteries. The batteries can accept 50a each of charge current, so I set the max current to 50 so I don't over charge, and a max voltage of 54.2v, set to start charging when voltage gets to 52.0v.This *should* keep my batteries plenty charged since I'm only running an LED light, my chest freezer, and refrigerator. About 1500w of power used per day. However, about every 2 weeks, the batteries get low enough to shut off at 49v. I've checked and rechecked my system, and everything looks right, but then at some point, it stops charging again and the batteries die. Today for example it was bright and sunny all day. The fridge was running when I left for work, but I came home and it was off again.Long story short, this charger doesn't keep the batteries charged so much as extend the time between having to charge them on grid power.

I have had it for a year and a half and have not had any issues. It is connect to 6 batteries and 800 watts of solar panels at 24 volts. Good value and quality. Is noisy when the fan runs but it's in my garage so it doesn't bother anybody. Not a lot of options. Just basic.

Have had these for 2 years 2 different systems and have had no problems and seam very efficient. easy to set up. fans do get a bit loud. really kick on any thing above 700 watts. they are in a cargo trailer and have 30,000 miles on them now.

My system is very simple - 4 solar panels wired in parallel (190 watts maximum each), 1 battery (12 VDC, 200 amp hour AGM), 12 volt system - worked OK for 2 months. Yesterday the display stopped working and it is not charging the battery. I turned on the system today and the battery voltage never increased even though it was the middle of the day with plenty of sunlight overhead. Perhaps the company will replace this unit or refund my money. Otherwise I am stuck with a broken charge controller.

I have an older yellow version of this charger, which I bought here at Amazon back in July 2021. It has worked flawlessly. First charging four AGM batteries and now, since three months ago, charging four LiFePo4 100ah batteries. So, when I needed another MPPT charge controller, I didn't hesitate to purchase this updated version.I recently purchased a shipping container for my backyard, which I plan to run off the grid as much as possible. At the moment, this MPPT charge controller is attached to 10 100 watts panels connected in series, charging four AGM batteries. As with the older version, this charge controller is working flawlessly, keeping the batteries charged.Especially for its low price, you can't go wrong with it. But don't let its low price, as compare to similar charge controllers, fool you. It's well built and can charge different types of batteries, including lithium. I recommend it.

I am running four 455 watt 45 volt panels in parallel, and this unit handles them perfectly, it is producing up to 62amps so far on the cooler days full sun, and will still output 25 to 30 amps on totally clouded days. It charges my four lifpo4 batteries in a 24v set up very quickly, then stops once fully charged, I like that you can manually adjust the amperage and voltage separately, and it records daily maximum production for amps and wattage. The output load is capable of 60 amps DC as well for a water heater I am using. I will be buying a second unit for an expansion right away.
