The instructions are not clear and are at least partly incorrect. Step 2 says to connect the solar panel and the controller, and "both indicator lights on the controller light up **at the same time.**" I'm thinking this reads as if they are both on and don't flash. Actually, the LEDs flash rapidly between green and red, and I was concerned something was going to blow up. Step 3 says to connect the batter from the controller to the battery, and the "only the CHARGING light on the controller is on." After the battery was attached, the controller continued flashing rapidly about another 1-1/2 minutes, so I'm thinking, "What the heck is it doing?" FINALLY, the light stays red. There is a 20 watt solar panel and a 20 A-Hr battery, so it charges up all day Saturday and it still charging at around 2:30 PM Sunday. I'm wondering how long this will go on for, and then suddenly the alternating red and green lights come on before my eyes. Step 4 says "both lights on the controller light up again" when the battery is fully charged at 14.2V, and the picture shows both red and green LEDs lit up, but the voltage was only around 13.4V. I have no idea if this is working correctly or not.

Plugged unit into 100w 12v solar panel and controller instantly melted and burned. Customer service 0 help just said too much power and did not tell max input voltage could be. Can only email no phone. Said they would issue credit and then nothing . would not recommend. Ordered controller from different company and it worked fine.

Hi, this charge controller seems to work well and seems very well made. I think it is good value for the money. Simple and straight forward.I bought it to use with a 3.5 watt coleman solar battery maintainer which runs ok without a charge controller but.im.not sure if it adjusts for AGM batteries. This charger controller is made to adjust and it work fi e with the panel.The power consumption is good, because it has a diode to protect back flow of current.I havent checked it with a meter, but it is holding my battery at a good charge.The coleman solar maintainer also has a diode.One question i have is that the directions say to hook the charge controller up to the solar panel first and then the battery.I have contacted them to ask if there is an internal protection for that. I assume there is. Because most charge controllers need to be hooked to the battery first and then the panel.So i did it the safe way until i hear back from them. i will update if i get any more information.Update : i heard back from solperk and they explained it was okay to hook up the panel to the controller first. Heres what they said.Hi,For a 12V8A controller, it doesn't matter if you connect the battery or the solar panel first. You read elsewhere that connecting the batteries first is because their controllers are powered by batteries, ours uses solar panels for power, so both are fine. Also the controller will automatically recognize between lead acid, AGM, or Lithium Iron Phosphate batteries and adjust itself so please feel free to use it.Have a nice day.SOLPERK SERVICE

This charger works great, it's small and waterproof. I use it to keep a trailer battery charged.The unit I received had the red/black wires reversed, and the seller confirmed that this was an error in manufacturing, and shipped a replacement unit.

SimpleWorks great to keep my trail cam battery (12 amp hour lead acid battery) charged up with a 10 watt panel. Battery and controller are housed in a 50 cal ammo can.

We have a driveway gate powered by a 12-volt marine battery. For years, the batteries have been charged by direct connection to a small 10-watt solar panel. Although that should be just fine for a lead-acid battery, I figured what’s the harm of using an actual battery controller? And if it extends the battery life by even one year, it will be more than worth it.Once mounted and connected, the charger came to life with a red LED showing its receiving power and charging. Alas, we had several cloudy days, so the green LED didn’t come on for nearly a week, but once the skies cleared and we got full sun, the green LED did come on showing the battery had finally reached 14.x volts (whatever the specs call for).It’s supposedly fine for outdoor use, but ours is mounted inside the control cabinet. I even punched a small hole and added a plexiglass window so I can see the controlled without removing the cover.

The controller for my solar panel had broken. I bought this is a replacement and spliced it in line and it worked absolutely perfect. Keeps my boat battery charged so I can pump the water out even when it sits for weeks. Keeps the battery comfortably at 100%, I could not be happier with the product. It's very affordable and does a great job charging.
