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

I bought one of these about 3 years ago (under a different brand at the time) and have been very happy with it. I particularly like the fact that the display shows both the load current and the charging current in addition to the battery voltage. I was recently looking for a similar device with better features (more programming options) and couldn't find anything better and recently bought a second device for a different system. Cons: Not UL or ETL listed. There doesn't seem to be a way to set the charge voltage (although the maximum charge voltage is adjustable). Five stars because I couldn't find anything better in a similar configuration (30A, low cost).
