12V/24V Automatic Detection: It is equipped with an automatic system for voltage recognition and can automatically identify system voltage once connected.
Lithium Battery Activation: Switch on the "lithium mode" and connect your battery and solar panel. It will work its magic and the battery will spring back to life.

After only five months of charging my Lithium battery and in spite of the Load light being lit, this charger is no longer powering my Load. I'll give a complete report after this issue is addressed by the manufacturer.

mppt! yup awesome so far...quick outdoor and extensive indoor tested with all connected before an off-grid excursion, but so far so good. Had to grind down some o-ring cables to make them fit, but otherwise okay. If using heavier gauge wires to reduce voltage/power loses(like me) beware that you will need to figure out how to fit your terminals connections to this controller as screw and width sizes become a major issue.

Installed to regulate solar blanket for camping. Seems to work well and very happy.

My only complaint is that it doesn't have an indicator that it is working like the display screen on some cheaper brands. Other than that, seems pretty straightforward and seems to work fine.

Being new to solar, I am building my own portable power station and in need of a small MPPT charge controller (10-20 amp) that will charge 12 or 24 volt batteries. While learning and testing, I have this unit paired with 2 100w folding panels and a 500w inverter. Hooked up my shop fan to it that draws around 90w, while fan is running fine, the charge controller is outputting around 50w to the battery. Everything seems to be running fine and I can run the fan all day as long as the sun is out. Now I just need larger panels to step up the game.

This is a solid basic solar charge controller for Lithium batteries. As shown on the sales screen, all feedback information is performed through LEDs. There is no programming except for a simple selector button to set the charger for the proper battery type. The battery type setting is announced by a dedicated LED light color. Green for lithium iron (LiFePO4) batteries as is printed in the legend by the light. Is the charge controller receiving power from the panels? Check the dedicated "Solar" green LED. Is a load being powered? There's a green - "Load" LED light for that answer. Battery state-of-charge? Three red LEDs light up in sequence with the amount of battery power in the battery.All of the normal protections are built in and automatic. Over-current and -temperature. Under-voltage. Reverse polarity is protected. As with most solar charge controllers, there is no under-temperature charging protection. Charge your lithium battery at temperatures below 32 degrees F. / 0 degrees C. and you have probably ruined your battery, unless the battery has built-in low temp charging protections - ones that either inhibit charging when too cold or heat the battery to an acceptable charging temperature before letting in charge current. Most do not.What's not to like? Well, for the data driven, there is no information window. How much voltage are the panels producing? How many amps are going into/out of the charge controller? There is no telling, unless you hook up a separate power monitor - or two. That is the price of simplicity. Let the automation do its work and remain ignorant of the nitty-gritty details. With a 50V and 20A power limitation, be conscious of how many panels are feeding your charge controller. The controller works well within it's design capabilities.My one big gripe! The screw type terminals for all wiring inputs/outputs are TOO small. I like to use low resistance 10AWG wire size. I could barely shove 12AWG wire into the terminals. Granted, even 12AWG wire is over-kill for a small charge controller, but I want that option.But it is a good, small, simple charge controller for those just starting out and with modest needs.

Bought this one for 70 bucks instead of a 30 dollar one because it did not have a full led display. Thinking it wouldn't use power when it's night. It uses power. Not a smart controller. Once sun completely sets, this stays lit up with battery type and amount. Unfortunately. Thus using power when none is being made.Screw terminals are very small. Yellow jackets fit the wires, yet the screw terminals only big enough for blue, so bare wire was only other option. Not happy I paid 50 dollars more than the other ones just to end up with a power hungry, tiny terminal Christmas Tree

The opening where you connect the cable is two small. I connected the largest wire I could fit to it about three inches long and then connected a more suitable gauge wire from there. Hopefully that cuts down the resistance.

Works as described. Keeps my solar panels charging my LiFePO4 batteries for my Yaesu FT-818 at an appropriate voltage and current while operating the transceiver portable. While I haven't tested the USB power ports yet, I am very pleased with this purchase after using it for about half a month.

The thing worked great for about 48 hours. I had it hooked to 2 renogy 100W watt panels in series charging 2 100AH batteries. I got a 500W pure sinewave inverter running a small 3.5CF deep freezer drawing about 60W. I got up 3 hours ago and the things just flashing random lights in full sun. It was cheap enough I'll take the loss and move on to something else. In the meantime my jackery 1000 will be running the system, it can power this fridge for nearly 3 days with no sun so nothing should spoil on me. I think I'll go victron this time.
