20A solar charge controller/regulator with LCD display for 12V/24V/36V/48V battery

Take charge of your solar power system with our 20A Solar Charge Controller/Regulator. Designed for versatility across 12V, 24V, 36V, and 48V battery systems, this intelligent controller puts you in command. Its vibrant LCD display and advanced features mean you can monitor and fine-tune your energy flow. This ensures your batteries last longer and your solar setup runs smoother. Say goodbye to guesswork and hello to complete control over your clean energy.

Here’s what makes this solar charge controller an essential addition to your system:

• Universal Compatibility: Automatically detects and works with 12V, 24V, 36V, or 48V battery systems (gel, sealed, or flooded).
• Clear LCD Display: Offers advanced monitoring and programming capabilities right at your fingertips.
• Full Control: Adjust various charging parameters and load work modes to suit your specific needs.
• Customizable Settings: Program your own system settings, freeing you from factory limitations.
• PWM Technology: Utilizes Pulse Width Modulation for enhanced battery charge acceptance and extended battery life.
• Battery Health: Capable of recovering lost battery capacity over time.
• Robust Protection: Includes comprehensive electronic safeguards:
  • Prevents reverse current at night
  • Automatic cutoff for over-charging prevention
  • Protects against deep discharge
  • Safeguards against overheating
  • Overload and short circuit protection
  • Reverse polarity protection
• High Power Handling: Compatible with solar panels up to 320W (12V), 640W (24V), 960W (36V), or an impressive 1.2kW (48V) for large off-grid systems.
• Wide Voltage Input: Accepts solar input voltages up to 96V, allowing use of higher voltage on-grid solar modules.
• User-Friendly Interface: Features intuitive LED indicators and a built-in temperature sensor.
• Performance Monitoring: Real-time display of solar panel and battery performance, plus an energy statistics counter.
• Flexible Load Control: Programmable load work modes with a timer function.
• Personalized Battery Type: Create and save a "user-defined" battery type with custom parameters.

For enhanced system stability and safety, especially with larger setups, we recommend using a 48V battery bank. This approach often leads to a more secure and reliable solar charging system due to lower current ratings when paired with an inverter.

Connectivity and control are key with this unit. Its advanced communication technology offers multiple ways to interact with your system:

• Remote Monitoring: Connect to an optional MT50 remote meter with an LCD screen for convenient off-site monitoring.
• Mobile App Access: Integrate a Wi-Fi module (sold separately) to monitor and adjust settings directly from your mobile device.
• PC Connectivity: Use an RJ45 to USB cable (sold separately) to connect to a PC or laptop, allowing you to manage parameters through a dedicated computer program.

Through any of these methods, you gain access to a wealth of data, including voltage, current, battery state of charge, accumulated energy, and min/max voltage readings. You can also actively modify battery type and capacity, set precise charging voltages for different stages, define stage durations, and fine-tune load settings.

For optimal charging precision, the controller includes terminals for connecting an external remote temperature sensor. This allows for more accurate battery temperature measurement and ensures the charging process is perfectly optimized for battery health and longevity.
