Solar Panel Controller BT-1 Bluetooth Module 12V 24V 20A Discharge Maximum Panel Voltage 100V 90V for Solar Controller System Battery Charging Regulation
BT-1 Bluetooth Solar Panel Controller Module for 12V 24V Systems
Managing battery voltage in a solar power setup requires a controller that can handle variable panel input and deliver reliable regulation. This BT-1 model serves as a dedicated Bluetooth module for solar controller systems, supporting both 12V and 24V battery banks. It is suitable for off-grid installations, backup power systems, and mobile solar setups where wired monitoring is inconvenient. The module provides a maximum panel voltage tolerance of 100V at 25°C and 90V at -25°C, with a continuous discharge current of 20A. This ensures compatibility with common solar panels and battery configurations without overstressing the controller components.
Features and Construction
The BT-1 Bluetooth module is built around core electronic components optimised for solar charge controller applications. Its design focuses on voltage regulation and wireless communication, making it a practical addition to existing solar systems.
Voltage and Current Ratings
The module is rated for 12V and 24V battery banks, covering the most common voltages in residential and small commercial solar installations. The maximum panel voltage is specified as 100V at 25°C, reducing to 90V at -25°C to account for temperature effects. Discharge current is rated at 20A continuous, suitable for moderate loads such as lighting, pumps, or small appliances.
Bluetooth Connectivity
Integrated Bluetooth module (BT-1) enables wireless communication with a compatible monitoring device. This eliminates the need for direct cabling to the controller, simplifying setup and allowing real-time data access from a distance. The Bluetooth function is built into the module itself, so no additional adapters are required.
System Compatibility
Designed specifically for solar controller systems, this module works with controllers that support 12V/24V inputs and the specified voltage limits. It is not a standalone controller but a add-on module that enhances monitoring capability. The one-colour option (BT 1 Bluetooth module) includes the module in its standard configuration.
Uses and Placement
The BT-1 Bluetooth module is intended for use in solar power systems where remote monitoring and voltage regulation are needed. It is most effective in fixed installations such as cabins, caravans, boats, and small off-grid buildings.
Off-Grid and Backup Systems
For off-grid homes or backup power systems, the module provides wireless insight into battery voltage and controller status. This helps users make informed decisions about load management and charging cycles without manual checks.
Mobile and Portable Solar
In mobile applications like recreational vehicles or marine setups, the Bluetooth module reduces wiring complexity and allows monitoring from a central location. The compact design fits easily into existing controller enclosures.
Installation and Setup
Installation follows standard solar controller wiring: connect the module to the battery and solar panel respecting polarity and voltage limits. Once powered, the Bluetooth module pairs with a smartphone or tablet app for configuration and data display.
Benefits and Buying Value
The BT-1 module adds wireless convenience to a standard solar charge controller without requiring a complete system upgrade. It is a targeted solution for users who already have a 12V or 24V solar setup and want remote monitoring capability.
Simplify Monitoring
With built-in Bluetooth, users can check battery voltage and system status from a distance, reducing the need for physical access to the controller. This is especially useful in hard-to-reach installations.
Cost-Effective Upgrade
Instead of replacing an existing controller, this module adds Bluetooth functionality at a lower cost. It is suitable for retrofitting to compatible systems, extending the life and usefulness of current equipment.
Reliable Voltage Handling
The specified maximum panel voltages (100V at 25°C, 90V at -25°C) and 20A discharge current provide a clear operating envelope, helping to prevent damage from overvoltage or overcurrent scenarios. This gives users confidence in the module's operational limits.
