This Felicity 45A MPPT Solar Charge Controller is an advanced, auto-detecting unit for 12V/24V systems, providing up to 45A charging current with over 98% MPPT tracking efficiency and 80V max PV input to optimize energy harvest from solar arrays up to 2600W at 24V. It supports multi-stage (three-stage) charging for lead-acid, AGM, gel, flooded, and lithium batteries, with built-in protections against overcharge, short-circuit, reverse polarity, and overheating via an efficient heatsink and IP20/IP31 enclosure for reliable, quiet performance. Featuring an LCD display for real-time monitoring, RS485/CAN communication for remote app-based oversight, parallel operation support, and compatibility with major inverters, it's an ideal choice for scalable off-grid, residential, and backup solar applications.
