Victron BlueSolar Light 12/24-20 20A PWM Charge Controller

Product Description

The Victron BlueSolar Light 12/24-20 20A is a PWM charge controller designed for 12 V or 24 V solar systems that require higher current than the 5 A and 10 A versions. It automatically detects battery voltage, applies three-stage charging to extend battery life, and offers a load output with low voltage disconnect to protect against deep discharges. It features integrated day/night lighting control with a timer, ideal for autonomous lighting without the need for external controllers. Its two-digit LED display simplifies adjustment and diagnostics, while its low self-consumption maximizes available energy in small and medium-sized installations.

Main Features

• 20 A nominal current for 12/24 V with automatic detection.
• Three-stage charging: initial, absorption (≈14.2 V/28.4 V), and float (≈13.8 V/27.6 V) for lead-acid batteries.
• Output with LVD: low voltage disconnect (≈11.2 V/22.4 V) and defined manual/automatic reconnection.
• Integrated lighting control: day/night mode and programmable timer from the LED display.
• Protections: overload, output short circuit, PV/battery reverse polarity, and overtemperature.
• Common positive, IP20, and self-consumption <10 mA for greater system efficiency.

Advantages or Benefits

• Extends battery life thanks to stage management and precise low voltage disconnect.
• More available power than the 5/10 A versions, while maintaining simplicity and reliability.
• Automates lighting without additional accessories, reducing costs and installation complexity.
• Clear interface with LED display: configuration and verification in seconds, without external equipment.
• Low self-consumption to maximize usable energy in systems with few panels.

Purpose or Applications

Perfect for autonomous public and residential lighting, solar signage, small installations in caravans and boats, remote sensors, electric fences, and 12/24 V systems that require a robust PWM controller with lighting control.

Technical Specifications

Compatibilities
