Review on 🔋 EPEVER MPPT Solar Charge Controller 30A 12V/24V Auto DS2 + UCS Intelligent Modular-Designed Regulator: The Ultimate Solution for Sealed, AGM, Gel, Flooded, and Lithium Battery Charging (30A,Triron3210N) by Danny Porter

Actually there are two of them, replace this 20A with 30A. The best charge controller! The company's support team sent me the complete addressing protocol for the RS485 port so I could connect an industrial computer (PLC) to it. They were just great as it's a bit out of the norm. I have AmpereTime's 12V LiFePO4 batteries in parallel and in series for a nominal 24V system and it charges them well. The initial programming is a bit cumbersome at the beginning. look, but overall pretty basic. It is very important that LiFePO4 batteries are NOT charged below 32F. This is a rare problem in my crawl space, but it can happen, and batteries are too expensive to screw up with frozen charging. The charger has a setting for high and low battery temperatures, but the manual doesn't say if charging would stop. So I tested it with ice and in fact it stopped charging at 0°C (32°F) and wouldn't let it start again until it reached 10°C (50°F).
