Review on 🌞 BlueFire LCD Digital Display Solar Panel Regulator Charge Controller 30A 12V/24V 360W/720W with Dual USB Ports by Joe Greiner

Finally installed and seems to be working well. I'm still learning all the functions, but it's already the second day and the batteries are charging! I noticed a high noise coming from the device. This annoys me because I have good hearing and can still hear it in my ears despite the background noise. Not a big problem, but annoying for me. I installed the unit in a week and used it for three days camping, charging two 12v deep cycle batteries in my RV. I also used the load side of this and it worked fine. Definitely could use some better instructions and feature explanations.
