30A PWM Solar Charge Controller, 12V 24V Dual USB Solar Panel Battery Intelligent Regulator with LCD Display, Auto Parameter Adjustable, Timer Setting, Multiple Load Control Modes

This is a basic PWM charge controller. Had it about two months, have two 100w panels and a 30a 12v battery powering some strip lights and phone charging. Works well so far. Only complaint is the power cable screw holes are small, you will need a small phillips head screw driver.It accepts up to 400w @12v or 800w @24v

Works great with my 100watt panel. I would buy this again.One characteristic of these chargers that I wasn't aware of is they won't turn on if the battery is below a certain voltage. I thought it was broke until I found this out

Works okay, but the last unit I had was 12V only, and not 12/24V. There's no switch to toggle between the two. It senses the voltage and configures itself to that mode automatically. I noticed something it though my 12V battery need to be charged at 24V. For the price its not bad, but the setup and menu is confusing, and the instructions are in Chinglish, so you sometimes have to read between the lines. I can make it work but again there are better options in the same price range.
