Exotronic Tracer Dream 75V Bluetooth Series: Advanced MPPT Solar Charge Controller for 12V Systems

Maximise Your Solar Harvest with Precision MPPT Technology

The Exotronic Tracer Dream 75V Bluetooth Series is engineered to extract the maximum available power from your solar array, even under rapidly changing light conditions. At its core, a high-speed 32-bit CPU drives advanced Maximum Power Point Tracking (MPPT) with up to 99.5% tracking accuracy, ensuring your batteries receive optimal charge throughout the day. This controller is purpose-built for 12V off-grid solar systems in caravans, RVs, boats, and remote installations where every watt counts.

Unlike basic PWM controllers that can leave significant energy unharvested, the Tracer Dream’s MPPT algorithm continuously scans the PV curve, including multi-peak scenarios caused by partial shading or mixed arrays. This means faster battery charging and better performance in real-world conditions, from cloudy mornings to intense midday sun.

High-Efficiency Power Conversion

Featuring Synchronous Rectifier Technology, the controller achieves a circuit transfer efficiency of up to 98.5%, minimising heat buildup and power loss. This not only improves overall system yield but also supports reliable operation at full rated current without thermal throttling. The wide MPP voltage range (battery voltage +2V to 65V) and maximum PV input voltage of 75V provide flexibility in panel configurations, allowing series wiring of multiple panels while staying within safe limits.

Intelligent Battery Management

Protect and extend the life of your battery bank with a sophisticated 3-stage charging profile (Bulk, Absorption, Float) and support for Sealed, Gel, Flooded, and Lithium battery types. The controller ships defaulted to Lithium, with user-adjustable parameters for custom setups. Integrated temperature compensation automatically adjusts charge voltages based on ambient conditions, preventing overcharge in heat and undercharge in cold—critical for Australian climates.

Comprehensive digital safeguards include protection against reverse polarity, overcharging, over-discharging, overload, short circuit, and PV reverse current. These features reduce the risk of system damage and downtime, giving you confidence in unattended operation.

Wireless Monitoring and Control

Stay connected to your energy system via the built-in Bluetooth module. Using the free LD iConnect app (available for Apple and Android), you can monitor real-time data, adjust settings, and review historical logs from your smartphone. The onboard LCD display also provides instant access to key parameters without needing a phone.
