Review on 🌞 WindyNation P30L 30A Solar Panel Charge Controller with LCD Display, Customizable Settings, and User-Friendly Interface by Dustin Berry

The P30L will work as a controller but as some others have said it doesn't handle phases very well (you really can't see it happening when not so much) I found my batteries bad, over time they had some quirks to the point where I just wasn't comfortable anymore, I bought a 40a model from Grape Solar with Bluetooth etc and it's a much better controller (you have to call Grape Solar to get the app and admin password to change settings, but they actually answer the phone and it's a quick call!).
