Review on 🔆 EEEKit 20A Solar Charge Controller - Intelligent Regulator with Dual USB Port, LCD Display - 12V/24V PWM Auto Parameter Adjustable - Blue by Committed Schmidt

I tried two different solar panels. It seems to work fine but I'm not sure. I bought it to replace a basic charger for an alarm system, but I'm pretty sure the first solar panel I used it with blew up (it was small and over 10 years old). I just installed it with a new one. Let's see how it works. The problem I'm having with this controller has to do with the terminals that the wires screw into. There is no support behind the board and if you use some force to tighten the screws, the board will flex. This does two things: 1) prevents the screws from being overtightened, and 2) breaks the alignment on push button controls so they don't work. To level them you have to turn everything off, open the container box and level everything again. But if you reinstall it, it can easily happen again.
