BT-1 Solar Panel Controller with Bluetooth Module for 12V/24V Solar Systems
This solar panel controller provides essential regulation between solar panels and battery banks in off-grid power installations. The BT-1 model combines core charging functionality with modern connectivity through its integrated Bluetooth module, allowing wireless monitoring of system performance. With support for both 12V and 24V battery configurations and a substantial 20A discharge current rating, this controller suits various solar power applications where reliable battery charging and load management are required.
Features and Construction
The BT-1 solar controller incorporates several key specifications that determine its performance in solar power systems. These electrical ratings ensure compatibility with common solar panel arrangements and battery bank configurations while maintaining safe operating parameters across temperature variations.
Electrical Specifications
This controller supports both 12V and 24V battery systems, providing flexibility for different power requirements. Its 20A discharge current rating indicates the maximum continuous current it can supply to connected loads. The 100V maximum panel voltage specification at 25°C allows connection of solar panels in series configurations to achieve higher voltages, which can reduce power loss in transmission cables. At lower temperatures, the maximum panel voltage adjusts to 90V at -25°C to account for the voltage increase that occurs in photovoltaic panels during cold conditions.
Connectivity and Control
The integrated Bluetooth module distinguishes the BT-1 model from basic solar controllers by enabling wireless monitoring capabilities. This connectivity feature allows users to check system status, battery charge levels, and power generation data without physical connection to the controller. While specific Bluetooth range and compatibility details aren't provided, this wireless interface represents a practical enhancement for solar installations where regular monitoring is beneficial but physical access may be limited.
Uses and Placement
This solar panel controller is designed specifically for solar controller system applications, with no alternative use cases specified. Its electrical specifications and Bluetooth functionality define its operational context within solar power installations.
Solar Power Applications
The controller's primary application is within solar charging systems where photovoltaic panels supply power to battery banks. Its voltage and current ratings make it suitable for small to medium-sized off-grid installations, including remote monitoring stations, agricultural systems, recreational vehicle power systems, and backup power configurations. The temperature operating range from -25°C to 25°C supports deployment in various climate conditions where solar power systems typically operate.
System Integration Considerations
When integrating this controller into a solar power system, the 12V/24V battery support requires matching the controller configuration to the existing battery bank voltage. The maximum panel voltage specifications must be respected when designing the solar array configuration, particularly in colder climates where photovoltaic panel voltage increases. System designers should consider the 20A discharge current limitation when sizing connected loads to prevent controller overload.
Benefits and Buying Value
The BT-1 solar panel controller offers specific technical advantages for solar power system implementations. These benefits stem from its combination of electrical specifications and wireless monitoring capability.
Practical System Advantages
The dual-voltage battery support eliminates the need for separate controllers when switching between 12V and 24V systems, providing configuration flexibility. The substantial 20A discharge capacity allows powering multiple devices simultaneously in off-grid installations. Temperature-compensated voltage specifications help prevent system damage in extreme weather conditions by adjusting maximum allowable panel voltages according to environmental factors.
Why Choose This Product
This controller combines essential solar charging functionality with modern wireless monitoring through its Bluetooth interface. The electrical specifications support common solar power configurations while the temperature-adjusted voltage ratings account for real-world environmental variations. For solar installations where regular performance monitoring is valuable but physical controller access is inconvenient, the wireless capability provides practical utility without compromising core charging functionality.
