Product Description

The Steca PR1515 12/24V PWM Controller with Display is designed for off-grid installations that require higher charging current without sacrificing detailed visual control. It uses shunt topology with MOSFETs and multi-stage PWM (bulk, boost, float, and monthly equalization), with Steca AtonIC SOC determination for precise battery management. Its graphical LCD display shows symbols and numerical values for voltage, current, and energy; the integrated energy logger allows performance analysis and can be reset by the user. Button programming, dusk/dawn functions, and automatic load disconnection/reconnection simplify daily operation.

Main Features

Nominal current: 15 A in 12/24 V systems with automatic detection.
PWM algorithm with temperature compensation and monthly equalization for maintenance.
Graphical LCD with AtonIC SOC, digital reading of V/A/Wh, self-diagnostic messages, and guided menu.
Data logger (resettable accumulated energy), manual load switch, and late/night/dawn modes.
Comprehensive electronic protections and automatic fuse: overload, deep discharge, reverse polarity, short circuit, over/undervoltage, overtemperature, and night return.

Advantages or Benefits

More usable power (15 A) for systems with more panels or higher consumption without increased complexity.
Prolonged battery life thanks to precise voltages, thermal compensation, and controlled equalization strategy.
Clear monitoring on the device itself: actual charge status, daily energy, and alarms.
Quick installation: 12/24 V detection, generous terminals, and intuitive LCD menus.
Proven reliability with automatic load reconnection and factory protection package.

Purpose or Applications

Recommended for off-grid homes, telecom, video surveillance, outdoor lighting, caravans, and boats with medium consumption. Ideal when detailed local control and energy logging are required without adding external devices.
