40A 12V 24V 48V Solar Charge Controller With Wifi Monitor Function PWM LCD Regulator For Lifepo4 Lead Acid Gel Battery

Important Note:
The APP is compatible with Android and Hongmeng systems only—iOS is not supported. APP language is English only. Please review these limitations before purchasing.
Features
- Industrial-grade main chip for reliable performance
- Large LCD display with adjustable charging and discharging parameters
- Full 3-stage PWM charging management
- Built-in protection: near-load, short circuit, open circuit, and reverse connection—all self-recovering without controller damage
- Dual USB ports for flexible charging options
- WiFi app for real-time monitoring and configuration
- Battery temperature detection function (optional)
Specifications
- Model: PV-40A
- Charging Current: 40A
- MAX PV Voltage: 12V system <25V / 24V system <50V / 48V system <100V
- USB Output: 5V 2A MAX
- Standby Current: 12V <80mA; 24V <45mA; 48V <30mA
- Product Size: 170×135×70mm
- Operating Temperature: −20℃ to +50℃
- Max PV Panel Capacity: 12V system 520W / 24V system 1040W
Important Installation Notes
- This controller auto-detects 12V/24V/48V—ensure your battery has sufficient voltage for proper recognition before first installation
- Use short battery cables to minimize voltage loss and ensure accurate battery type detection
- Compatible with ternary lithium, LiFePO4, and lead-acid batteries
- Use only with solar modules; do not connect alternative charging sources
- Mount on a flat, well-ventilated surface to manage heat dissipation during operation
Installation Method
- Connect battery to controller (recommended: add an air switch between controller and battery for protection). LCD will display parameters—set battery type accordingly
- For DC load control: configure output mode first, then enable the DC output disconnect switch
- Connect solar panel PV to controller. When PV input voltage falls within the charging range, the controller enters charging state
- Recommended: Add air switches to battery, solar panel, and load circuits for enhanced protection
Package Included
- 1× Solar Controller Unit
- 1× Detailed User Manual
