Key Features
- Industrial-Grade MPPT Technology: Continuous bidirectional tracking achieves up to 99.9% tracking efficiency. Anti-backflow circuitry ensures stable, low-heat operation for long-term reliability.
- Smart Voltage Auto-Recognition: Automatically detects 12V or 24V battery configurations. Compatible with Lead-Acid, Lithium-Ion, and LiFePO4 (Lithium Iron Phosphate) battery types — simply select your battery profile and go.
- 8-Layer Self-Recovering Protection: Comprehensive safeguards include overcurrent, short circuit, open circuit, reverse polarity, overload, overcharge, undervoltage, and overvoltage protection. Triple-stage MPPT charging preserves battery health and extends service life.
- Clear LCD Display: Real-time monitoring of charging status, charge/discharge current, cumulative energy generation, and temperature. Supports parameter adjustment, battery type switching, and power-off memory so your settings are never lost.
- Dual USB Output Ports: Two built-in USB ports (5V/2A max each) let you charge devices directly from your solar system — no extra inverter needed for everyday gadgets.
- 3 Flexible Output Modes: Choose from Always-On, Timed (3 programmable timer settings), or Dusk-to-Dawn (light-controlled) output modes — perfect for lighting control, security systems, and off-grid setups.

Frequently Asked Questions
Q: What battery types are compatible with this MPPT solar charge controller?
A: This MPPT solar charge controller is compatible with Lead-Acid, Lithium-Ion, and LiFePO4 (Lithium Iron Phosphate) batteries. The system automatically detects 12V or 24V configurations and lets you select the correct battery profile via the LCD display for optimal charging performance.
Q: What is the difference between the three output timer modes?
A: The controller offers three output modes: Always-On (load output runs continuously), Timed (you program up to 3 custom on/off timer settings for scheduled operation), and Dusk-to-Dawn (light-controlled mode that automatically turns the output on at dusk and off at dawn — ideal for solar garden or street lighting). The 8V photovoltaic panel threshold triggers the light-control function with a built-in delay to prevent false switching.
Q: How does MPPT charging compare to a standard PWM charge controller?
A: MPPT (Maximum Power Point Tracking) technology continuously samples the solar panel's output and adjusts its operating point to extract the maximum available power at any given moment. This results in 15–30% more charging energy delivered to your batteries compared to a standard PWM (Pulse Width Modulation) controller, making it particularly advantageous in partially shaded conditions or when panel voltage significantly exceeds battery voltage.
Q: Is this solar charge controller safe to leave unattended?
A: Yes. The controller features 8 layers of self-recovering protection — covering overcurrent, short circuit, open circuit, reverse polarity, overload, overcharge, undervoltage, and overvoltage — so the system automatically recovers from faults without manual intervention. The power-off memory function also retains your custom settings if power is interrupted.
