The Victron Cyrix-ct 12/24V-120A (CYR010120011R) is a fully automatic, microprocessor-controlled battery combiner relay for 12V or 24V DC systems. It engages when charging is detected and disconnects when discharge begins, ensuring priority charging of the starter battery. With intelligent trend detection, bidirectional voltage sensing, Start Assist function, and no voltage loss, it is an ideal diode-isolator alternative for marine, automotive, or RV dual-battery systems.

Victron Energy Cyrix-ct 12/24V-120A (CYR010120011R) is a smart battery combiner designed to automatically manage charging between starter and auxiliary batteries. This voltage-sensitive relay engages when charging is detected and disconnects when voltage drops, protecting the starter battery from discharge.

The Cyrix-ct uses intelligent voltage trend monitoring to avoid unwanted switching and supports bidirectional voltage sensing from both battery terminals. It features auto-ranging for 12V and 24V systems, IP54 protection, and Start Assist mode to manually parallel batteries for emergency engine starting.

Key Features:

Intelligent relay for automatic battery combining and isolation.
12V/24V auto-sensing with trend-based voltage logic.
Zero voltage drop – unlike traditional diode isolators.
Bidirectional voltage sensing – engages when either battery is charging.
Start Assist – manual parallel for emergency engine start.
Over-temperature protection with automatic re-engagement after cooldown.
Compact, waterproof housing – IP54 protection rating.

Typical Applications:

Marine dual-battery systems with alternator charging
RVs, motorhomes, and off-road vehicles with auxiliary batteries
Automotive battery banks with charge protection

Note: The Cyrix-ct 12/24V-120A model does not include LED indicators or a control cable—those are available on the 230A version. Always mount close to the starter battery and ensure proper fuse sizing for safety.
