High Efficiency Dual Battery Solar Charge Controller MPPT - 20A 12V or 24V

High Efficiency Dual Battery Solar Charge Controller MPPT - 20A 12V or 24V: Advanced Power Management for Dual Battery Systems

The High Efficiency Dual Battery Solar Charge Controller MPPT - 20A 12V or 24V offers a robust solution for managing solar energy in systems with two independent batteries or battery banks. This controller is ideal for campervans, motorhomes, boats, or any setup with separate engine and leisure batteries, ensuring efficient charging and optimal performance.

Key Features:

1. Dual Battery Charging:

   • This 20A MPPT solar controller can charge two batteries simultaneously. The main battery receives the majority of the power, while the secondary battery gets a trickle charge of up to 1A, keeping it topped up and ready for use.

2. Maximum Power Point Tracking (MPPT) Technology:

   • MPPT technology significantly improves the efficiency of your solar system compared to standard PWM controllers. It handles a wide range of solar input voltages, making it compatible with standard 12/24V solar panels and multiple panels with voltages up to 100V. The maximum combined solar input power is 260W for a 12V system and 520W for a 24V system.

3. Comprehensive Protection Functions:

   • The controller includes a full suite of protection features: reverse current protection, over-charging prevention, short circuit protection, and reverse polarity protection. It is water-resistant (IP33 rating), offering protection against water sprays.

4. Advanced Battery Compatibility:

   • Compatible with a wide range of battery types including Gel, AGM, Lead-Acid Flooded, and Lithium (LiFePO4 or Li-NiCoMn) batteries.

5. Advanced System Functionality:

   • The controller auto-recognizes 12/24V battery systems and features an LCD screen showing real-time charging parameters (voltage, current, state of charge, and accumulated energy). It includes easy-to-use buttons for selecting battery type, changing temperature units, and resetting counters. The system also has a low power mode to reduce standby consumption when no solar power is available.

6. Current Limiting Function:

   • Allows for the addition of more solar panels to the system in the future, maintaining a 20A current limit.

Connectivity Options:

1. Remote Meter MT11:

   • Compatible with a remote meter with an LCD screen for system performance monitoring and parameter adjustment.

2. Wi-Fi Module:

   • Can create a Wi-Fi network for monitoring and adjusting parameters through a free mobile app (available for Android and iOS). Requires an RS485 to RJ45 port adapter.

3. Bluetooth Module:

   • Connects to a mobile phone or tablet for parameter monitoring and adjustments via a free mobile app. Requires an RS485 to RJ45 port adapter.

4. RS485 to USB Cable:

   • Allows direct connection to a PC/laptop for monitoring and adjusting settings using the Solar Station Monitor program (Windows-based PCs only). This connection also supports creating user-defined battery types and setting specific charging parameters for lithium batteries.

Additional Features:

• Temperature Monitoring:
  • Built-in temperature sensor and intelligent heat-dissipating design, with an option to connect a remote temperature sensor for precise battery temperature measurement and optimized charging.

The High Efficiency Dual Battery Solar Charge Controller MPPT - 20A 12V or 24V is a versatile and advanced solution for managing solar energy across dual battery systems, ensuring efficient energy utilization and comprehensive system protection.
