PWM Regulator Steca Solarix PRS3030 12/24V 30A
Modelo: Solarix PRS3030- Sku: STECREG004
- Vendor: Steca
Specifications
Product Description
The PWM Controller Steca Solarix PRS3030 12/24V 30A is the highest capacity model in the PRS family, designed for off-grid solar installations that require high currents without sacrificing the robustness and ease of use characteristic of Steca. It implements a series topology with MOSFETs and multi-stage PWM charging (bulk, boost, float, and monthly equalization), optimizing battery condition and extending its service life. Its automatic 12/24 V detection, internal electronic protections, and low self-consumption allow for the construction of reliable and efficient systems with minimal supervision.
Main Features
- Nominal current: 30 A at 12/24 V (auto).
- Multi-stage PWM management with monthly equalization and temperature compensation.
- Comprehensive electronic protections: overload, deep discharge, reverse polarity, short circuit, over/undervoltage, overtemperature, and night return, with electronic fuse.
- Multicolor LED indicators for SOC, operating status, and alarms; automatic load reconnection.
- Robust construction: IP31, wide thermal range, and large terminals for secure wiring.
- Advanced functions with Steca PA RC100 (remote control, night/dusk mode, and threshold adjustment).
Advantages or Benefits
- Supports larger PV arrays and loads, ideal for 400–800 W kits at 12 V or 800–1600 W at 24 V (indicative estimates, verify design by Voc/Isc).
- Protects the battery against intensive use thanks to precise charging voltages and controlled equalization.
- Minimizes downtime with automatic reconnection and comprehensive electronic protection.
- Direct installation and minimal maintenance: quick reading via LEDs, no display required.
- Scalability and control via RC100 accessory for projects with night-time automation.
Purpose or Applications
Recommended for off-grid homes with higher consumption, outdoor lighting, construction site cabins, communication systems, video surveillance, caravans/boats with multiple DC circuits, and small pumping systems. It is the ideal 30 A PWM controller when extra capacity is needed at a contained cost.
