The Victron Cyrix-ct 12/24V-230A (CYR010230010R) is a heavy-duty microprocessor-controlled battery combiner designed for high-power DC systems. It automatically connects batteries in parallel when charging is detected and disconnects during discharge, with no voltage loss. Featuring bidirectional sensing, LED status indication, a control cable, and emergency Start Assist function, it ensures reliable power distribution in marine, RV, and off-grid installations.

Description
Ask a Question

Victron Energy Cyrix-ct 12/24V-230A (CYR010230010R) is an intelligent, heavy-duty battery combiner relay that automatically manages charge distribution between batteries. When one battery reaches a charging voltage, the Cyrix-ct engages to allow parallel charging; it disconnects when the voltage falls to prevent unwanted drain.

Unlike diode isolators, the Cyrix-ct has zero voltage loss, maintaining proper charging voltages from alternators and chargers. It features automatic 12V/24V detection, LED status indication, and includes a 1-meter control cable for emergency manual activation (Start Assist).

LED Status Indication:

LED ON: Batteries engaged (connected)
LED flash every 10 sec: Disengaged
LED flash every 2 sec: Connecting
LED blink every 2 sec: Disconnecting
LED blink every 0.25 sec: Alarm (e.g., overtemperature, high voltage, low voltage)

Key Features:

Automatically connects/disconnects batteries based on voltage trends.
Bidirectional voltage sensing – engages when either battery is charging.
Start Assist function allows manual battery parallel for 30 seconds.
Includes LED indicators and 1-meter push-button control cable.
Zero voltage drop – unlike diode isolators, no alternator compensation needed.
Thermal protection with automatic recovery after cooldown.

Typical Applications:

Marine power systems with house and starter batteries
RVs and vehicles with auxiliary battery setups
Off-grid energy systems requiring automatic battery management

Note: For safe operation, install appropriate fuses in the battery circuit. The Cyrix will not engage if battery voltage is below 2V (12V system) or 4V (24V system).
