High TR3215BN high-efficiency 30 A MPPT solar charge controller for 12/24 V off-grid systems, with remote LCD meter and 5 m cable — ideal for boats, caravans and small renewable installations.

• MPPT technology: This solar charge controller uses the most advanced Maximum Power Point Tracking technology to maximise energy harvest as sunlight and temperature vary.
• PV input and power: PV open-circuit voltage (Voc) up to 150 V. Supports up to 390 W (12 V) or 780 W (24 V) combined solar input; ideal for higher-voltage panels charging lower-voltage batteries.
• Full system protection: This charge controller features a comprehensive set of electronic protection functions including reverse-current cut-off, over-charge and deep-discharge prevention, solar-panel over-voltage, overload, short-circuit and reverse-polarity protection.
• Remote meter / display: The controller comes with a remote LCD meter with 5 m cable. This meter displays charging parameters such as voltages, currents (solar/load), state-of-charge, accumulated charge/discharge energy and min/max voltage readings.
• Factory default or personalised charging: This solar charge controller with a remote meter allows you to either use standard factory settings or personalise a range of exclusive settings for greater control — amend battery type and capacity; select charging voltages for different charging stages; specify the duration of each charging stage; and create a user-defined battery type with custom charging parameters.
• Additional features & battery types: This unit can work with sealed, gel, flooded or user-defined lead-acid batteries. Supports load control for DC devices and pumps.
• Controller specifications & communications: The most advanced MPPT technology to ensure high efficiency of your solar system. Communication port: RS485 / RJ45 interface. Grounding: negative common ground. Current limiting function for safe operation.
• Electrical & mechanical: Self-consumption: <60 mA (12 V), <30 mA (24 V). Working temperature: -35 °C to +55 °C (-31 °F to +131 °F). Enclosure: IP30. Size: 20 x 16 x 7 cm. Weight: 2.2 kg (4.85 lb). Multiple mounting holes for ease of installation.
