MPPT Charge Controller 120A – SCCM12048-II

Description The Felicity Solar SCCM12048-II is the heavy-duty powerhouse of the Series II lineup. Boasting a massive 120A charging capacity, this controller is designed for industrial-scale off-grid systems, large residential estates, and commercial solar farms. It is built to handle high-wattage arrays that would overwhelm standard controllers. The Industrial Standard: Power & Performance The SCCM12048-II is the flagship of Felicity’s charge controller range, offering the highest current output and the most robust voltage handling in the series. Massive Energy Harvest: Capable of managing up to 6,600W (6.6kW) of solar power on a 48V system. This allows you to connect over a dozen high-efficiency 550W panels to a single controller. Superior Voltage Range: Features an expanded Maximum PV Input Voltage of 195V DC, giving you much more flexibility to string panels in series for long-distance runs with minimal power loss. Dual-Fan Active Cooling: Unlike the smaller fanless models, the 120A unit uses a heavy-duty intelligent cooling system with dual fans to maintain 120A output even in the high-heat environments typical of the Far North or Littoral regions. Parallel Ready: Features CAN communication support, allowing multiple 120A units to work in parallel for massive solar arrays exceeding 50kW. Technical Specifications Feature Specification Model SCCM12048-II Maximum Charge Current 120A Nominal System Voltage 12V / 24V / 48V (Auto-Detection) Max PV Input Voltage (VOC) 195V DC Max PV Input Power 1,650W (12V) / 3,300W (24V) / 6,600W (48V) MPPT Efficiency 99.5% Conversion Efficiency 98% Weight 6.5 kg Battery Types Lithium (LiFePO4), Gel, AGM, Flooded Advanced Safety & Protection Given the high current levels, the SCCM12048-II includes the most advanced protection hardware in the family: Transient Surge Protection: Built-in 4500W per port surge suppression to protect against lightning-induced spikes. Industrial Cooling: High-temperature disconnect and reconnect logic to ensure the unit never operates outside its safety envelope. Precision Sensing: Includes a Remote Temperature Sensor (RTS) port and Battery Voltage Sense terminals for extremely accurate charging, regardless of cable length. MODBUS / RS485 / WiFi: Full suite of communication ports for integration into professional Energy Management Systems (EMS). Critical Installation Note: At 120A, heat is your biggest enemy. You must use at least 35mm² to 50mm² (1/0 AWG) high-quality copper battery cables. A 150A DC circuit breaker is mandatory between the controller and the battery bank for safety.
