Description
The Victron Cyrix-ct Intelligent Battery Combiner (CYR010120011R) is designed for off-grid and backup systems to ensure optimal battery performance without the need for traditional diode isolators. By using a microprocessor-controlled relay, the Cyrix-ct automatically connects batteries in parallel when one of the batteries reaches a pre-set voltage, indicating it's being charged. It disengages when the voltage drops below the float level, ensuring that no battery is left in a discharged state.
The Cyrix-ct 12/24 uses intelligent battery monitoring to prevent unwanted switching, unlike simpler battery combiners that disconnect due to short, high-amperage loads or when voltage drops too quickly. It continuously evaluates the voltage trend (whether increasing or decreasing) and reverses its actions only if the trend has changed over a set period. This dynamic approach prevents connection failures with discharged batteries or batteries affected by short-duration, high-amperage loads.
With overheating protection, auto-ranging voltage detection, and no voltage loss, this battery combiner is a reliable and energy-efficient choice for systems requiring parallel battery connections. The Cyrix-ct also offers emergency parallel connection (via Start Assist), allowing manual connection of batteries for 30 seconds in case of discharged starter batteries.
Key Features
- Intelligent battery monitoring – Automatically connects and disconnects batteries based on voltage trends, preventing unwanted switching
- No voltage loss – No need to increase output voltage from alternators or chargers, making it an excellent replacement for diode isolators
- Overheating protection – Disengages in case of excessive contact temperature and re-engages once cooled down
- 12/24V auto-ranging – Automatically detects system voltage for easy installation
- Emergency parallel connection (Start Assist) – Allows manual parallel connection for 30 seconds in case of emergency
- Bidirectional voltage sensing – Monitors voltage of both batteries, ensuring reliable connection even when one battery is being charged by an external charger
- Dual power supply – Enables operation even if one battery voltage is too low
- IP54-rated protection – Resistant to dust and water for reliable performance in harsh environments
- Compact design – Ideal for off-grid, marine, and backup systems
- 5-year warranty – Backed by Victron's trusted reliability
