This little charge controller has already been through a tough North Dakota summer- and is still working great!
I thought for sure I was going to have to build a weatherproof enclosure for this as the sides are open for ventilation. I figured dirt and rain would have this system of the fritz in just days. But since this was an experimental system for solar powered pumps, I figured I might as well sacrifice this inexpensive controller to see where the limits are.
To my surprise, the system has been wet, dirty and shocked hard when the 2X4 it was attached to fell over in a rain\wind storm. So far, it still works perfectly. It appears there is some sort of coating on the circuit board that insulates it from the environment! Whoever built this understood it's a field unit and designed it accordingly.
The screws on the base can be tightened very tight to hold wire connectors securely- without stripping or breaking the device. The screws are made from plated metals to prevent corrosion and the base where the screws attach to is metal too. No worries about breaking this device with field use when you really need to torque the wires down hard. This has hard metal where it counts!
The unit comes with two open holes on the side for screwing it onto a piece of wood. (Or you could even tack it on with a nail.)
The drawing for connections is universal and obvious. If you can put in a car battery, you can install this with a solar panel and batteries.
As to it's ability, I paired this with two recycled 8AH 12V Sealed Lead Acid (SLA) batteries. It does a better job charging these than my expensive battery "conditioner" that's 20 times bigger and heavier than this controller.
It's meant to be paired with a solar panel and if you are looking for its match in ruggedness and price, check out the ECO-WORTHY 20 Watts Epoxy Solar Panel I reviewed. I got really lucky and found two very inexpensive systems that were both ideal matches for my tough applications.
If you are looking for systems to use outside in a garden or farm environment, I recommend these two systems!
Put the Eco-Worthy 20 watt epoxy solar panel (crazy tough- I seriously abused mine and it looks brand new,) with this controller and keep any small scale battery array or starting batteries fully charge all the time. Auto-detects 24V and 12V battery arrays, measures their charge state and decides to charge them when their is excess power. It also supplies the load with the solar cell when their is excess power and it won't let the batteries discharge below a recommend state while powering the load! That means it powers the load from the batteries at night and will turn the load off once the batteries reach their discharge point. So this is much more than just a charge controller! It's a smart load controller too!!!!!
Great for fountains, security\gate systems, outdoor video, cars\trucks\tractors\mowers\motorcycles\ski mobiles or any other vehicle that will sit a while and needs to have it's battery charged.
My application is for a small 12V water pump in garden. (Think small waterfall pump.) 350mA continuous water pump 24X7. Still going strong after a months use!

Dead output in 7 days
Stopped working in 7 days. My project consist of a 12 volt 5 watts solar panel, a 12 volt 7 amp battery, a 12 volt to 5V/2A power supply and the Docooler Solar Charge Controller. The load output worked sometimes, when it did my battery gets a full charge during the day, and supply my power supply during the night. However the controller NEVER show all 3 LEDs indicating full battery ( I tested the battery using a volt meter). Now on the 7th day all 3 LEDs stopped working and 1 to 2 volts on the load output. I then tried using it as a 24 volt setup, I got a 24V load output but still no battery level indication. UPDATE: I received a faulty one so the seller sent me a replacement and now after almost a year the replacement stopped working. No voltage on the load output. The seller quickly send a replacement but took a while to arrive because it came from China. It is working perfect, I guess I just got a faulty one the first time, I will upgrade to a 20 amps soon. The red LEDs indicating how much charge the battery has are very bright but they don't bother me, they actually gets brighter (one by one gradually) as the battery receives charge, so I can say I can "see" my battery charging.
