EPEVER Tracer4210AN G3
EPEVER MPPT Solar Charge Controller 40A 12V 24V Auto Max PV 100V Solar Panel Charger Regulator Common Negative Ground LCD Display for SEL Gel AGM FLD LiFePO4 Lithium Battery (Tracer4210AN-G3)
A 40 A MPPT controller for 12/24V systems with automatic voltage detection, an LCD, a 100 V PV input limit and room for 520 W at 12V or 1040 W at 24V. It has a LiFePO4 profile, user-defined charge voltages and a 40 A load output, which is double the 20 A of other controllers listed with a load output. Bluetooth is not built in, only an RS485 port, so it suits wired setups.
