120A 100%MPPT Solar Charge Controller 12V 24V 36V 48V Battery System MAX PV 200V High-Quality MPPT Solar Charge Controller - Optimize Your Solar Power System Efficiency! 🌟 This professional SCC MPPT solar charge controller is the core of your solar power system, designed to intelligently manage the charging and discharging of your batteries, protect your equipment, and maximize energy utilization. Suitable for residential, commercial, and off-grid solar setups, it supports multiple battery types and automatic voltage adaptation for hassle-free use.   ✅ Key Features & Advantages

• Automatic Voltage Recognition: Supports 12V/24V/48V auto-identification, with optional fixed 36V setting (note: 36V is not automatically recognized). No complicated manual voltage adjustment—just power on and use (restart required after manual voltage setting).
• High-Efficiency MPPT Technology: Boasts 99% MPPT tracking accuracy and 97% maximum charging efficiency, significantly improving solar panel energy conversion compared to traditional controllers. Minimizes energy loss and maximizes power output for your batteries.
• Multi-Battery Compatibility: Compatible with GEL, SLA, FLD, and custom (USR) lead-acid batteries, as well as various lithium batteries (3.2V 4-series/5-series LiFePO4, 3.7V 3-series/4-series polymer lithium). Customizable lithium battery charging parameters (CV/RCV) for optimal battery performance and lifespan.
• Comprehensive Protection Functions: Equipped with overcharge, over-discharge, PV over-voltage, controller overheating, short circuit, and reverse connection protection. Automatically shuts down or restores to protect your batteries, solar panels, and loads from damage. The controller stops charging when temperature exceeds 88°C and restarts when below 75°C.
• Flexible Load Control Modes: 6 adjustable load working modes to meet different needs: Regular (24h continuous work), Light Control (night work only), Reverse Light Control (day work only), Dual Time Control (light control first), Time Control (custom work time), and Charge-Only mode.
• Intuitive Operation & Display: Color LCD with backlight and 3 easy-to-use buttons (MENU, FORWARD, BACKWARD). Real-time display of system voltage, battery capacity, charging/discharging status, PV input voltage, and more. Easily set time, sound volume, and restore factory settings with simple button operations.
• Durable & Reliable Design: Iron case with heat sink and cooling fan for efficient heat dissipation, ensuring stable operation in harsh environments. Working temperature range: -10°C to +50°C; storage temperature range: -30°C to +80°C. High-current copper terminals (25 mm² / 3AWG) for secure wiring.
• Additional Functions: RS485 communication (RJ45 port) for centralized management and remote control; 10K temperature probe (3m line) for temperature compensation; cumulative charge/discharge statistics (resettable); fault code display for easy troubleshooting.

🔧 Installation & Usage Notes Wiring sequence: Connect batteries first → connect load → connect solar panels → connect inverter (if used). Disassemble in reverse order. Wrong wiring may damage the controller. For lithium battery users: Set system voltage first, then select the corresponding battery type (see manual for details). Operate within the allowed ambient temperature; derate if temperature exceeds the range.   📦 Package Includes 1 x MPPT Solar Charge Controller 1 x User Manual (English) We are committed to providing high-quality products and professional after-sales service.
