There is no maintainable part in the controller. User cannot disassemble or repair the controller without permission 2). before installing and adjusting the connection of controller, please make sure to disconnect the connection of photovoltaic panel and the fuse or breaker around battery terminal 3). after installation, ensure all the wire connections are reliable to avoid heat accumulation for virtual How to use: This item will be heated during operation. It is a must to mount it on the surface that made of nonflammable materials. Installation on large-sized metal piece is more beneficial to heat dissipation. Please follow the steps below in installation: 1)though the controller has inverse connection protection function, it is better to avoid the inverse connection of photovoltaic panel in engineered installation 2)Connection should be strong and reliable. Contact area of connector should be large enough to prevent virtual connection and heat accumulation caused by oxidation at connection Package included: 1 X Solar Controller 1 X User Manual

Product Reviews

Works well, good value, poor documentation.

This little controller is doing a good job! I have it managing the trickle charge into a vehicle I don’t drive all the time. There are two 18v. panels feeding the input and the controller is managing a 13v maintenance input to offset the alarm’s costant power consumption.At first I was concerned that the controller, which is hooked directly to the car’s 12v battery, might be damaged upon starting the car when the alternator kicked in, might provide a backflow of current into the controller.Turns out that there’s no problem there; the controller continues to work, suspending the “float charge” while the alternator is running, and no damage results from the extra car battery voltage.There would be five stars, but the so-called ‘manual’ is really a single piece of paper, folded into 1/3rd’s, and written in Chine-nglish. Quite a bit of useful information is missing, such as: a blinking arrow indicates a float charge and a solid arrow indicates a full-on charge mode. Another thing missing is a translation of what the battery types mean. What is “b01” or “B02” for example? The so-called manual tells you nothing.I found out that ‘b01’ is a sealed cell and “b02” is a vented cell battery.All-in-all the controller works as I’d hoped, provides a good value for the price and was easy to hook up.Work with it awhile and you’ll get the hang of the setting procedure

Works and is pretty resilient to connecting things the wrong way

Works and is pretty resilient to connecting things the wrong way. :-) . lcd is clear and easily readable. It doesn’t show you the wattage that the panel is producing but shows most anything else that is relevant. Navigating the options and settings can be challenging so take some time to go through them and figure out how they work. The options are available similar to programming a digital wrist watch. If connecting stranded wire, be sure and recheck the screwed down connectors after a day or so since the strands tend to compress resulting in a lose connection. Just re-tighten them, no need to remove the wires.

Perfect for my solar/battery application

This unit works well for my simple setup of getting power from a 100W solar panel, storing the energy in a deep cycle boat battery and driving 6X10W exterior garage spotlights.I use the timer (24= lights on all the time, 1-23 is how many hours after sunset the lights will stay on, or 0 will automatically turn them on at sunset and off at sunrise).You can also adjust the trickle charge voltage and at what point of battery drain the load will turn off and when it will be back on when charge has recovered. You can also adjust the controller to how many amp/hours your battery is. The 3 operate buttons: Scroll thru menus with left button, Turn load off/on with the right button, Hold for a couple seconds the left button to change parameters using the center and right buttons to adjust. Confirm changes by again holding the left button for a few seconds.The display is LCD and not lighted so don’t put it in a dark corner or you won’t be able to read it. Also, the LCD display is sluggish in my unheated garage at temperatures 20 degrees F and below. My unit is KLD1220 (20 amp) and I found an owners manual and promotional sheet on the internet. This unit does everything that I need for the price level.

Perfect device. Easy to set up. Just wish that the holes for wires were bigger.

Perfectly simple ONCE YOU READ THE INSTRUCTIONS. I couldn’t figure out why it wouldn’t turn back on in the AM after it reached low voltage at night. There’s a setting. It’s not obvious. But works perfectly once you follow the instructions. Who would have thunk it?Background: Using this with a 50Ah deep cycle battery to run fans, a light sensor switch, and thermostat switch all 12v in a greenhouse.

Works as advertised.

Works as advertised.I had a battery that I wanted to use as with a solar panel. I bought a large Battery Tender solar panel, but it was damaged and the controller portion didn’t work. I verified the panel itself was producing voltage. I bought a battery case and an inverter, and placed this on top. I hooked the solar panel to the input, and the output to the battery. So far it has floated the charge to the battery and maintained it topped off. The icons on the top show the panel, and the battery. It’s easy to see the battery voltage, and confirm that the controller is allowing the panel to charge the battery.

Works as described.

Items works as described, however I wanted to see charge current as well as output current which I did not find any way to display. If you want a no frills controller this seems to work well for that. If you want more information look at one of the better Mohoo controllers. I think for the price it works fine. I do like the input/output terminal configuration.It did say the float voltage was 13.7 default but mine always reset to 12.7 and I had to adjust it. It did pick up my battery type correctly.

Great unit and would have given 5 stars if manual came with it found one on line.

No documentation came with it, but all connection’s are clearly marked. Set up and made a camping solar generator. 100 watt solar panel was input power through a 2 pin power port cord. Battery was a 12 volt tractor battery, garden type. Output out of this was hooked up to a 300 watt inverter. Now I have USB on the unit but only for low draw devices as it will not handle more that 1 amp between the two USB combined. 12 volt from unit splits to 12 volt plug and inverter, inverter also has a 2.5 amp usb for charging battery packs.Testing in use shows that it works great and charges well at factory setting which are easy to set. Got manual off the internet. Output is very consistent and will shut down correctly to protect battery from over discharge. Once battery is charged it shuts down to protect from over charging, and will continue charging as battery level is used. I could put on another 100 watt panel but I don’t need it.I am very pleased with this unit so far and will update later if needed. Current use time is from November 29th 2016 to date.

I bought this for use in my rebuild of a 1976 Catalina 22 sailboat. It’s very basic but gets the job done. FYI, the usb ports will operate off the battery when the solar panel is unplugged or not charging. Figured they would but couldn’t find it stated anywhere.

Four Stars

works well

Small, but Mighty

Received this in a reasonable amount of time. I have used it several times when out camping with my trailer.

Lasted 3 months

Worked sufficiently for 3 months, but is now completely dead. My kit is connected properly and the controller screen has gone blank.

Good for the price.

Bought this to connect my 2 100watt solar panels on my travel trailer to a agm deep cycle battery. Although the instructions were a little difficult to follow, it did recognize…

Stopped charging after 7 months, 100W RV solar system

The unit worked for several months. For my 100W RV panel, the charge voltage from the panel would be about 14.5V and 5.5A when un bulk mode on a depleted battery.
