BT-1 Bluetooth Solar Panel Controller for 12V/24V Battery Systems

This solar charge controller combines essential charge regulation functionality with wireless monitoring capability through its integrated BT-1 Bluetooth module. Designed specifically for solar controller systems, it manages the charging process between solar panels and battery banks while allowing users to monitor system performance remotely. The controller accommodates both 12V and 24V battery configurations, providing flexibility for different solar power setups. With a maximum panel voltage rating of 100V at 25°C and 20A discharge current capacity, it handles moderate power requirements while maintaining safe operating parameters.
Features and Construction

The controller's core functionality centers around regulating charge from solar panels to connected battery systems. Its electronic circuitry monitors battery voltage and adjusts charging parameters accordingly. The inclusion of the BT-1 Bluetooth module represents a practical enhancement for system monitoring without requiring physical access to the controller unit.
Material and Build
Constructed from standard electronic components arranged for charge regulation functionality, the controller focuses on its primary purpose without unnecessary complexity. The Bluetooth module is integrated into the design rather than added as an external accessory. This integration maintains a consolidated unit that handles both charge control and wireless communication functions.
Size and Practical Fit
While specific dimensions aren't provided in the source materials, the controller is designed for integration into solar power systems rather than standalone decorative purposes. Its electrical specifications dictate physical installation considerations, particularly regarding cable connections and heat dissipation for the 20A discharge capacity. The unit accommodates standard solar installation practices without requiring specialized mounting equipment.
Uses and Placement

This controller serves as the central management component in solar power systems where batteries require regulated charging. Its application range focuses specifically on controller functions within solar installations, making it suitable for various scenarios from small off-grid setups to supplemental power systems.
Event or Professional Use
For professional solar installations or event power management, the Bluetooth functionality provides convenient system monitoring without interrupting operation. The 20A discharge current supports moderate power requirements for lighting, small appliances, or communication equipment. Temperature-dependent voltage ratings ensure reliable operation across seasonal variations that outdoor installations experience.
Everyday Home Use
In residential solar applications, the 12V/24V compatibility allows adaptation to different battery configurations that homeowners might employ. The wireless monitoring via Bluetooth enables checking system status from smartphones or tablets without accessing electrical panels. This simplifies routine monitoring for solar installations powering sheds, caravans, or as backup systems.
