Product Description

The Steca PR3030 12/24V PWM Controller with Display is the highest current model in the PR series, designed for demanding off-grid installations that require 30 A with advanced local control. It maintains the Steca philosophy: precise battery management through multi-stage PWM with monthly equalization, temperature compensation, and shunt topology with MOSFETs. The graphical LCD display shows the Steca AtonIC SOC, real-time voltage/current values, and accumulated energy thanks to the integrated data logger. Its package of electronic protections and automatic fuse provide safety against abnormal situations, while 12/24 V detection and automatic reconnection simplify daily use.

Main Features

Nominal current: 30 A at 12/24 V (automatic detection).
PWM charging algorithm with boost, float, and monthly equalization; temperature compensation.
Graphical LCD with AtonIC SOC, digital reading of V/A/Wh, and button-operated menus.
Resettable energy log and self-diagnosis with clear fault messages.
Functions: dusk/night/dawn modes, manual load switch, automatic disconnection/reconnection by SOC.
Total protections: overload, deep discharge, reverse polarity, short circuit, over/undervoltage, overtemperature, and night return.

Advantages or Benefits

More usable power for PV arrays and higher consumption, ideal for off-grid homes and small businesses.
Optimized battery health with precise voltages and an equalization routine that minimizes sulfation.
Local visualization and logging of parameters and energy without additional equipment.
Service continuity with automatic reconnection and comprehensive protection against electrical events.
Professional installation thanks to large-section terminals and intuitive LCD menus.

Purpose or Applications

Recommended for off-grid homes with medium-high consumption, outdoor lighting, site cabins, telecommunications, video surveillance, caravans, and boats with multiple DC circuits. An excellent option when 30 A with visual control and long-term reliability are required.
