Review on 【2021 Upgraded】 Solar Charge Controller with USB Port, Intelligent Regulator for Solar Panel Battery, Multi-Function Adjustable LCD Display Street Light Controller, 12V24V 30A by Thomas Henry

This is my first solar controller so to be honest I have no comparison with it. However, it was very easy to hook up and seems fairly accurate. do just that; now it jumps from 13.3 to 13.4 and the current falls as it should. While I have no real experience with these controllers, for $12 how can you go wrong? I will buy another one as a backup; hard not at this price. I don't know about people with serious solar systems; it might be a joke for them; however for a simple installation with one or maybe two batteries; Definitely.
