The Suoer Intellint PWM 20 A Charge Controller offers a highly functional, cost-effective solution for managing small off-grid solar setups—especially lighting-focused systems. Its combination of LCD monitoring, versatile control modes, USB outputs, remote capability, and robust protections make it attractive for DIY or low-cost commercial applications.

Features :

• PWM Charging Mode: Utilizes pulse-width modulation to regulate energy, balancing efficiency and cost
• Intelligent Control Mode: Provides more precise and optimized charging, minimizing power loss and improving energy usage
• User Interface: Equipped with an LCD display to monitor performance metrics (e.g., voltage, system state, local illumination time)
• Light + Time Control Modes: Offers combined light and timer control; includes multiple working modes such as:
  • Manual/Button mode
  • Light-controlled mode (photosensitive)
  • Light + timing mode
  • Delay-off mode
  • Circulation mode via clock
  • Optional settings for 0–24 hour on/off, and remote control
• Dual USB output: 5 V @ 1 A × 2 for charging small devices
• Infrared remote control support, with IR self-learning capability to operate DC loads wireless
• Adjustable Charge Voltage:
  • Low: 14.2 V
  • Default: 14.5 V
  • High: 15.2 V
  • This allows customisation across different battery chemistry
