SOLPERK 8A 12V Solar Charge Controller with LED Display, IP67 Waterproof PWM Intelligent Solar Panel Battery Regulator for 12V Batteries

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

Excellent product

Charged my LIPO battery perfectly using a 50W Renogy panel.

Using it to charge a 100ah LiPo battery from a solar panel. Works great.

Works great no issues so far, nice bright lights to let you see what’s happening
