Victron Battery Alarm GX

The Victron Battery Alarm GX is a compact and affordable alarm panel designed to monitor 12V and 24V battery banks, providing immediate audible and visual alerts when battery voltage moves outside of safe operating thresholds. Ideal for marine, RV, off-grid, and backup power applications, it offers a simple and reliable way to protect your battery system from over-voltage and under-voltage conditions.

Designed for ease of use, the Battery Alarm GX features programmable alarm thresholds and hysteresis settings via onboard DIP switches, allowing users to fine-tune low and high voltage alarm points to suit their specific battery bank without requiring any additional tools or software.

In addition to its audible buzzer and LED visual indicators, the Battery Alarm GX includes a potential-free relay contact with both normally open (NO) and normally closed (NC) outputs. This enables integration with external systems for remote alarm signalling or automated responses to alarm conditions.

The unit is housed in a slim plastic GX-style enclosure and can be panel-mounted using the included accessories or fitted within a compatible wall mount enclosure. Its compact footprint makes it well suited for dashboards, electrical panels, and control boxes in space-constrained installations.

Built for reliability in demanding environments, the Victron Battery Alarm GX is a straightforward yet effective protection and monitoring solution for any 12V or 24V battery system.

Features

Audible and Visual Alarms

The Battery Alarm GX triggers both a buzzer and LED indicator when battery voltage falls below or rises above the programmed thresholds, ensuring alerts are immediately noticeable in any environment.

Programmable Alarm Thresholds

Alarm set points for low voltage (Ulow) and high voltage (Uhigh), as well as hysteresis values, are fully configurable via onboard DIP switches — no software or external devices required.

12V and 24V Battery Bank Compatibility

The Battery Alarm GX is compatible with both 12V and 24V nominal battery banks, with voltage range selection made easily via DIP switch settings.

Potential-Free Relay Contact

A built-in relay with normally open (NO) and normally closed (NC) contacts allows the alarm to interface with external systems, sirens, or automation equipment for remote signalling.

Compact GX Panel Design

The slim GX-style plastic enclosure is designed for clean panel integration and is compatible with Victron's wall mount enclosure accessories for flexible installation options.

Simple Panel Mount Installation

Straightforward installation with included mounting accessories makes the Battery Alarm GX easy to fit into dashboards, control panels, and electrical enclosures with minimal effort.

Low-Cost Battery Protection

Designed as an affordable monitoring solution, the Battery Alarm GX delivers essential overvoltage and undervoltage protection without the need for complex battery monitoring equipment.

Wide Application Suitability

Suitable for marine, recreational vehicle, off-grid, and backup power installations where reliable battery voltage alerting is required across 12V or 24V systems.
