Review on 30A Solar Charge Controller with Dual USB Ports, LCD Display & Multi-Function Adjustable, Intelligent Regulator for Solar Panels, Batteries & Street Lights by Patrick Arnautov

Feels like something cheap considering it's clearly a bargain! At the same time, I honestly didn't have high hopes that the thing would even work, but surprisingly, this solar charge controller turned out to be a decent thing! It has adjustable settings to ensure you don't overcharge, overcharge, you can set it up so you can't use the battery until it reaches a certain voltage after charging a dead battery. Good basic functions. LCD screen, buttons, under the controller are connectors for the ends of the cables you use from the solar panel, battery and device/load. + - for each of them a Phillips screwdriver to securely tighten and fix the wires. I'm new to all this, I have a standalone mini backup power system. I plan to expand my project, this was a good starter controller for me and maybe you too.
