MPPT Charge Controller 20A 24V – SCCM2024-II

Description The Felicity Solar SCCM2024-II is the compact, 20A entry-point model in the Series II MPPT family. Specifically engineered for small, high-efficiency 12V and 24V setups, it is a favorite for rural electrification, security camera systems, and basic home lighting kits in Cameroon where space and budget are key considerations. Key Features: Pro-Level Efficiency for Small Systems 99.5% MPPT Tracking: Don’t let the small size fool you; it uses the same advanced tracking algorithm as the 120A industrial models to ensure you get power even on rainy or overcast days. Lithium Battery Support: Fully compatible with LiFePO4 batteries. It includes the Series II “Wake-up” feature to restart lithium batteries that have shut down due to low voltage. Ultra-Compact & Fanless: The unit is designed with a high-grade aluminum back-plate for passive cooling. Because it has no internal fan, it is 100% silent, making it ideal for installation inside bedrooms or quiet offices. Digital Monitoring: The clear LCD screen shows real-time stats like charging current, battery voltage, and historical energy production ($kWh$). Technical Specifications Feature Specification Model SCCM2024-II Rated Charge Current 20A System Voltage 12V / 24V (Auto-Detection) Max PV Input Voltage (VOC) 95V DC Max PV Input Power 280W (12V) / 550W (24V) MPPT Efficiency 99.5% Peak Conversion Efficiency 98% Protection Class IP20 (Indoor) Dimensions 201 x 137 x 65 mm Safety & Protection Despite being the smallest in the range, it carries the full Series II protection suite: Over-Temperature Protection: Safely derates power if the ambient temperature exceeds 55dC. PV/Battery Reverse Polarity: High-speed electronic protection against “plus/minus” wiring errors. Automatic Overcharge Protection: Transitions from Bulk to Absorption to Float to keep your batteries healthy and prevent gassing. Surge Protection: Built-in transient surge protection for the communication and power ports. Installation Tip: For this 20A controller, use 4mm² or 6mm² (10 AWG) copper wire. Since the max VOC is 95V, it works perfectly with a single large 450W/550W panel or two smaller 200W panels connected in series.
