The Felicity 45A MPPT charge controller (Model: SCCM4548) is designed to automatically work with 12V, 24V, and 48V solar systems. It uses Maximum Power Point Tracking (MPPT) technology to optimize charging efficiency. General specifications Maximum charging current: 45 Amps.Nominal system voltage: Automatically detects 12V, 24V, or 48V DC.Maximum solar input voltage: 145V.High efficiency: The controller achieves a maximum efficiency of up to 98%, which can increase energy harvest by 25% to 30% compared to conventional PWM controllers.Supported battery types: Compatible with a wide range of batteries, including AGM, gel, and flooded lead-acid batteries. It also supports lithium batteries, though the voltage settings must be manually configured.Charging algorithm: Uses an optimized 3-stage charging process (Bulk, Absorption, Float) to maximize battery life and performance. For lithium batteries, the process is two-stage. Maximum input power by system voltage 12V system: 625 Watts.24V system: 1250 Watts.48V system: 2500 Watts.
