Victron Battery Alarm GX: Precision Battery Monitoring with Audible and Visual Alerts

Protect Your Battery Investment with Reliable Voltage Surveillance

The Victron Battery Alarm GX is a compact, professional-grade monitoring panel engineered to safeguard your battery bank from damaging voltage conditions. Designed for 12V and 24V systems, it provides continuous surveillance and immediate alerts when voltage levels deviate from safe thresholds. This proactive protection helps prevent deep discharge damage and overcharge stress, extending battery service life in caravans, marine installations, off-grid solar setups, and backup power systems.

Unlike generic voltage alarms that offer limited configurability, the Battery Alarm GX features DIP-switch programmable thresholds and hysteresis, allowing precise customisation to match your specific battery chemistry and application requirements. The integrated potential-free relay contact (COM, NO, NC) enables seamless integration with external monitoring systems, generators, or load-shedding devices, adding a layer of automated control to your energy management.

Clear, Immediate Alerts When It Matters

Visual and audible indicators ensure you are alerted to voltage anomalies without delay. A high-intensity red LED signals over-voltage, a blue standby LED confirms active monitoring, and a red low-voltage LED warns of under-voltage conditions. The onboard buzzer provides an unmistakable acoustic alarm, with a physical toggle switch allowing you to silence it when needed without disabling the visual indicators or relay output.

Flexible Integration with Your System

The potential-free relay contact is a standout feature for advanced installations. With normally open (NO) and normally closed (NC) terminals, the Battery Alarm GX can trigger external alarms, disconnect loads, or start a backup generator automatically when voltage thresholds are breached. This galvanic isolation ensures compatibility with a wide range of control circuits, making it a versatile component in both simple and complex DC systems.

Key Features

• Monitors 12V or 24V battery banks with programmable low and high voltage thresholds
• Audible buzzer and three LED indicators (high, standby, low) for instant status recognition
• Potential-free relay output (COM, NO, NC) for external device control or remote signalling
• DIP-switch configuration for alarm setpoints and hysteresis, no software required
• Compact panel-mount design (120 x 65 x 17 mm) for easy integration into control cabinets
• Low power consumption ensures minimal impact on battery state of charge

Engineered for Demanding Environments

Built to Victron's professional standards, the Battery Alarm GX features a robust PCB with secure screw-down terminal blocks and brass mounting inserts. The low-profile design allows recessed panel mounting, saving space in crowded electrical enclosures. Its simple, reliable architecture avoids the complexity of microprocessor-based monitors, reducing points of failure and ensuring long-term dependability in mobile and remote applications.

Applications

• Caravan and RV house battery monitoring
• Marine battery banks on yachts and powerboats
• Off-grid solar and wind energy storage systems
• Backup power and UPS battery surveillance
• Industrial equipment with critical DC power requirements
