45A 12V/24V/48V MPPT Charge Controller – Felicity Solar SCCM4548
Product Overview
The Felicity Solar SCCM4548 is a reliable 45A MPPT Solar Charge Controller designed to maximize the performance of off-grid and hybrid solar systems. Using advanced Maximum Power Point Tracking (MPPT) technology, it extracts more energy from solar panels, increasing charging efficiency by up to 25–30% compared to conventional PWM controllers while delivering a maximum conversion efficiency of 98%.
Compatible with 12V, 24V, and 48V battery systems, the SCCM4548 automatically detects battery voltage (except lithium batteries, which require manual configuration). It supports lithium, AGM, GEL, and flooded lead-acid batteries, making it suitable for residential, commercial, agricultural, and backup solar applications.
