Works as advertised. I Like the voltage and current displays. Needed for my lifeso4 battery and rv solar panels. I do not use the power out option.

I have a small piece of land out in the woods and use quite a few small solar stations to do things like run cameras and sensors as well as a few other experiments. I have been using those cheap blue chargers that are labeled MPPT but are really just PWM, they have been fine but only last about a year or so in the elemenets (even when in protective cases). I usually have a single panel connected to them 100 watts or less. I have tried a few higher end models but MPPT just does not really pay off that much at this low wattage and PWM is fine.I was happy to see this come up for review as I am always looking for something that might last longer or be easier to use. Out of the box this feels way better than those blue PWM chargers. From the plastics to the LCD to the terminals it is clear this is much higher quality.I connected this one to one of my remote cameras. This consist of a single 100 watt solar panel, a 12V, 14aH LiFeP04 battery and a 900Mhz P2P transceiver (this is in a highly wooded area about 400' from the closest access point).The screen on this is very easy to read. I really like how it is setup to cycle through all the values (solar input, output, battery etc.). I was easily able to setup the charging / disconnect points for my specific battery. I also appreciate the terminals, while it is a bit weird how they stick out they are larger than the ones on the blue chargers. Another bonus is the mounting kit and hardware that this comes with, was not expecting that but a nice addition if your mounting this. Most of my stations are setup with a battery box that fits everything inside of it. I have been running this station with this charge controller for about 3 weeks now and have had no problems.I really love how well this communicates the status of what is coming in from the panel and what is going out to the load side. It really makes it easy to calculate how well the panel is doing (just by multiplying the voltage of the panel by the amps coming in you get the watts the panel is producing).This is not much more than the cheap blue controllers, no doubt in my mind next time I have to order another charger it will be this one.

I bought this because of its compact size. I was trying to use it to charge lithium batteries at 24v. Things started off fine. I had configured the charging profile to be custom. It configured to charge to 28V and then stop. Well after my battery hit about 25.4V or so the charger was reading 100% and stopped charging. Now why would you allow a user in custom mode to set the upper voltage cutoff you want to a number that the charger won’t allow?! The instructions were worthless. Waste of money. Don’t bother.

simple installation. works as it should. Nothing difficult about its function. plug and play after wiring solar plug for your panels.

The last charge controller I tried out (before this one) was a pain in the butt to change settings on. This one is the exact opposite. You just hold the up/down button for a couple of seconds to get into the settings, tap it again to cycle through them and tap the other button to change them. As soon as you're done you can either hold the up/down button for a few seconds to exit or it will exit itself after a bit.Now, granted, there are many less options you can actually change on this charge controller, but it has the most important ones. One thing that wasn't intuitive was the Load Mode setting. It defaults to 15 and can be adjusted between 0 and 17. It makes sense after looking through the small manual it comes with though. A setting of 15 means the load output is manually actuated. Press the load button and it turns on or off. That's it. A setting of 17 means it's always on no matter what. A setting of 0 means it'll turn on only when there's no daylight detected. I assume that checks that by if it's getting power from the solar panel or not?Modes 1 through 14 are less obvious. It says "DC load turns off according to timer. 1-14 indicates Timer setting hours." and the definition they give is "Daylight On/Timer Off". If I had to guess, I think I would assume that this means as soon as it detects that it's night time by there not being power coming from the panel it will turn on, and then wait between 1 and 14 hours before turning off. That would make sense given the Mode 0 auto-daylight setting.Mode 16 is a "testing mode" they say, where the "load turns on and off in quick succession".So, I gave this thing a try with a small 100w panel and a smaller 12v 12ah LiFePO4 battery and ran some various loads on it. In my quick test it worked great. It immediately started charging the battery up to full and had no problem with any of the loads, including the 5v 1a USB port, which is also controlled by the load switch.I like that it cycles through the displays, showing incoming voltage, battery voltage, battery charging amperage, load output amperage, battery state of charge and temperature. I don't know how it determines the battery state of charge though; there are no settings for battery capacity and with LiFePO4 you can't reliably go by the voltage level. It always read 100% for me. Maybe with lead acid batteries it would go by the voltage level; that would make sense.Additional settings would have been nice. Things like maximum charge amperage would help keep smaller batteries healthier, for example. Being able to set the battery's capacity would allow it to display the state of charge with lithium batteries more accurately. Speaking of that, it also doesn't have any absorption or float settings, which would certainly help getting the most life out of your batteries.Despite that, I still wouldn't have any problem using this controller for smaller, less critical purposes, like running lights at night or keeping vehicle batteries topped up.
