MPPT Charge Controller 45A 24V – SCCM4524-II

Description The Felicity Solar SCCM4524-II is a 45A MPPT charge controller specifically optimized for 12V and 24V systems. While it shares the same “Series II” intelligence as the larger models, it is a specialized, cost-effective solution for users who do not intend to scale up to a 48V battery bank. Key Features: Optimized for 12V/24V High-Efficiency Tracking: Uses the same 99.5% efficiency MPPT algorithm found in the premium Series II line, ensuring you extract every possible watt from your panels, even in the hazy or rainy seasons of Cameroon. Lithium Battery “Wake-up”: Features a dedicated protocol to revive Lithium (LiFePO4) batteries that have shut down due to low voltage, a critical feature for modern energy storage. Compact & Silent: Smaller footprint than the 48V models with a fanless design (passive cooling) for smaller loads, making it completely silent in a bedroom or office installation. Smart Monitoring: Integrated communication port (RS485) for connecting to external monitoring software or mobile apps. Technical Specifications Feature Specification Model SCCM4524-II Rated Charge Current 45A System Voltage 12V / 24V (Auto-Sensing) Max PV Input Voltage (VOC) 95V DC Max PV Input Power 625W (12V) / 1250W (24V) MPPT Tracking Efficiency 99.5% Peak Conversion Efficiency 98% Protection Class IP21 (Indoor) Net Weight 1.8 kg Comprehensive Protection Suite The SCCM4524-II is built to withstand the common electrical fluctuations found in local grids and off-grid setups: PV Reverse Polarity: Safety if panels are connected incorrectly. Over-Temperature Derating: Automatically lowers output if the unit gets too hot, preventing internal damage. Short Circuit Protection: Instant shut-off to protect your battery bank and wiring. Solar High Voltage Disconnect: Ensures the unit doesn’t fry if the panel voltage exceeds the 95V limit (e.g., in extremely cold, clear weather). Installation Note: Panel Limits Warning: Since the max PV voltage is 95V, you cannot connect more than two large solar panels (550W ) in series. If you have three or more panels, they must be connected in parallel or a series-parallel combination to avoid exceeding the 95V limit and voiding the warranty.
