BT-1 Bluetooth Solar Panel Controller for 12V and 24V Systems with 100V Input

This solar charge controller provides essential regulation for off-grid and backup power systems, automatically compatible with both 12-volt and 24-volt battery banks. Its design focuses on the core function of managing solar panel input, with a maximum voltage rating of 100 volts under standard 25°C conditions. The inclusion of a Bluetooth module, designated BT 1, offers potential for remote monitoring or parameter adjustment, adding convenience to system management. With a 20-ampere discharge current rating, it handles moderate power loads commonly found in small solar installations.

Features and Construction

The controller is built around the specific requirements of a solar charge regulation system. Its electronic design prioritises voltage conversion and battery protection.

Material and Build

The unit comprises standard electronic components assembled on a circuit board within a protective housing, as specified for the BT-1 model. The construction is dedicated to the single function of solar charge controlling, without extraneous features. The build quality corresponds to typical consumer-grade solar equipment for basic system management.

Size and Practical Fit

While exact physical dimensions are not specified, the controller is designed for wall or panel mounting within a solar power setup. Its form factor accommodates the necessary terminal connections for solar panel input, battery output, and load distribution. The unit should be installed in a location that allows for adequate airflow to prevent overheating during operation.

Uses and Placement

This controller serves as the central management unit for converting solar energy into usable battery power. It is applicable to various small-scale renewable energy setups.

Event or Professional Use

For professional or event applications, the controller can manage power for lighting, communication equipment, or small tools running on 12V or 24V DC systems. The Bluetooth functionality may allow for system status checks without physical access to the unit, which is useful in temporary installations or monitoring setups. The 20A rating suits applications like security cameras, signage, or temporary booth power.

Everyday Home Use

In residential settings, this controller is suitable for garden lighting, shed power, small water pumps, or as part of a backup power system for essential devices. Home users benefit from the automatic voltage detection between 12V and 24V systems, simplifying setup. The unit helps protect batteries from overcharging in daily solar applications.

Benefits and Buying Value

The controller offers straightforward solar power management with specific technical parameters suited to common small-system requirements.

Reuse and Low Maintenance

As a solid-state electronic device with no moving parts, the controller requires minimal maintenance beyond ensuring clean connections and proper ventilation. Its design for continuous operation supports long-term use in permanent installations. The components are selected for the specific task of charge regulation, promoting reliable reuse across multiple charging cycles.

Why Choose This Product

This solar controller provides clear specifications for voltage and current handling, with the added functionality of Bluetooth connectivity as indicated by the BT-1 module designation. It suits buyers who need a dedicated controller for small to medium solar panel arrays, particularly those using common 12V or 24V battery banks. The defined 100V maximum panel voltage and temperature-dependent rating offer transparency for system planning.
