Victron BlueSolar PWM Charge Controller LCD&USB 12/24-20 20A

Product Description

The Victron BlueSolar LCD&USB 12/24-20 20A is a robust and very easy-to-use PWM charge controller for 12 V or 24 V photovoltaic systems that require more current than basic models. It features a clear LCD display for system configuration and diagnostics, a three-stage intelligent charging algorithm that extends battery life, day/night lighting control with timer, and a dual 5 V USB port (2 A total) to power small auxiliary devices. With common positive, low self-consumption, and IP20 rating, it is a reliable solution for solar lighting, small off-grid installations, campers, and light marine applications.

Main Features

• 20 A charging current with automatic 12/24 V voltage detection.
• LCD display for parameter adjustment (voltages, LVD) and day/night timer.
• Three-stage charging: bulk, absorption (≈14.4 V/28.8 V), and float (≈13.7 V/27.4 V) for lead-acid batteries.
• Dual USB 5 V/2 A total for phones, routers, gateways, or sensors.
• Electronic protections: PV/battery reverse polarity, overload, short circuit, and overtemperature.
• Max. PV (Voc) 28 V (12 V system) / 55 V (24 V system) · self-consumption <10 mA.

Advantages or Benefits

• Protects the battery with appropriate charging voltages and low voltage disconnect to prevent deep discharges.
• Immediate local interface: the LCD display simplifies commissioning and maintenance.
• Fewer components in the panel: the integrated timer automates lighting without extra controllers.
• Practical efficiency: very low internal consumption maximizes energy available for loads.
• Quick and safe installation thanks to its common positive, accessible terminals, and compact size.

Purpose or Applications

Ideal for autonomous lighting of paths and signage, isolated cabins and cottages, campers/leisure boats, remote stations with telemetry, electric fences, and small 12/24 V self-consumption systems where simplicity, reliability, and battery protection are priorities.

Technical Specifications

Compatibilities

Compatible with 36-cell panels (12 V) and 72-cell or 2×36-cell panels (24 V). Recommended batteries: lead-acid AGM/GEL/flooded; possible use with LiFePO₄ only with BMS and proper control. Accessories: DC fuse holders and fuses, disconnectors, surge protectors, and solar cabling according to current and distance.

Victron BlueSolar LCD&USB 12/24-20 20A balances performance and simplicity, providing control, protection, and utilities in a compact format for medium-power 12/24 V solar systems.
