This controller offers an MPPT tracking efficiency of greater than 99.5% and maximum power conversion efficiency of greater than 98%. Maximum recommended PV input power depends on your battery system voltage: 12V battery system: up to 1200W solar 24V battery system: up to 2400W solar 48V battery system: up to 4800W solar ⚡ Important PV Voltage Limits The allowable solar array open-circuit voltage (Voc) changes depending on the battery system voltage. The following limits must be observed when designing your solar array: Battery System PV Open-Circuit Voltage Range Maximum PV Power 12V 20V–100V 1200W 24V 40V–145V 2400W 48V 80V–145V 4800W Important: Do not exceed the applicable PV open-circuit voltage range for your battery system. Excessive PV voltage may damage the controller. 🔋 LiFePO4 & Lithium Battery Compatibility The controller provides configurable battery charging parameters for LiFePO4, lithium and lead-acid batteries. The controller defaults to lead-acid settings, so the correct battery type and charging parameters must be selected before connecting and charging a lithium or LiFePO4 battery bank. Always ensure the charging settings are suitable for the specifications provided by your battery manufacturer. 📱 Monitoring & Communication An integrated RS485 communication port allows the controller to be connected to supported monitoring equipment. Optional accessories can provide PC monitoring or Wi-Fi/GPRS-based app monitoring. RS485 communication Optional PC monitoring Optional Wi-Fi monitoring module Optional GPRS monitoring module External battery temperature sensing Please note: Wi-Fi and GPRS monitoring hardware is optional unless specifically included with the product. 🛡️ Built-In Protection The controller incorporates multiple protection functions to help safeguard the solar charging system, including: PV over-voltage protection Battery reverse-polarity protection Battery over-voltage protection Battery over-discharge protection Charging over-current protection Equipment over-temperature protection Night-time reverse-current protection 🔧 Specifications Model JN-MPPT-CL 100A Rated Charging Current 100A Maximum Charging Current 100A Battery System Voltage 12V / 24V / 48V automatic identification 12V System Identification Range DC 9V–16V 24V System Identification Range DC 18V–32V 48V System Identification Range DC 42V–60V Maximum PV Power – 12V 1200W Maximum PV Power – 24V 2400W Maximum PV Power – 48V 4800W PV Voltage Range – 12V System 20V–100V Voc PV Voltage Range – 24V System 40V–145V Voc PV Voltage Range – 48V System 80V–145V Voc MPPT Tracking Efficiency >99.5% Maximum Conversion Efficiency >98% Full-Load Efficiency Up to 97% Charging Method 3-stage MPPT / Boost / Float Battery Compatibility Lead-acid, lithium and LiFePO₄ with configurable charging parameters Display LCD segment display with SET, ESC, UP and DOWN controls Communication RS485; optional Wi-Fi / GPRS monitoring Battery Temperature Sensor External temperature probe supported DC Load Output Operating Temperature -20°C to +50°C Storage Temperature -30°C to +70°C Humidity 10%–90% Protection Rating IP30 Dimensions 340 × 208 × 95mm Weight 3.6kg Recommended Copper Cable Size at 100A 20mm² / AWG 4 minimum as specified by manufacturer ⚠️ Installation Notes This is a high-current solar charge controller and must be installed correctly. The manufacturer specifies that installation should be carried out by a suitably qualified technician and that appropriate cable sizing, circuit protection, grounding and secure electrical connections must be used. The controller should be installed upright in a clean, dry and well-ventilated location, protected from direct sunlight and water. The IP30 rating means this controller is not designed for direct outdoor exposure. If an inverter is being used, connect the inverter directly to the battery bank rather than to the controller. 📦 Monitoring Options Depending on the configuration purchased, optional accessories are available for: RJ45 to USB PC communication RJ45 to Wi-Fi monitoring RJ45 to GPRS monitoring Warranty 2-year warranty from the date of sale, subject to correct installation and operation in accordance with the supplied instructions.
