## Summary description

Victron Energy charge relay CYR010120430 is a 12/24V, 120A battery charge relay designed to connect and disconnect batteries or battery banks automatically. It suits dual-battery systems and charging setups where controlled high-current switching is required. The relay enables safe charge distribution, simplifies battery management and protects charging circuits in automotive, marine or off-grid applications.

## Long description

The Victron Energy CYR010120430 is a robust 12/24V 120A charge relay engineered to manage the connection and disconnection of battery banks automatically. This device is essential for dual-battery systems, ensuring that the starter battery is prioritized while allowing the auxiliary battery to charge efficiently once the primary source reaches a sufficient voltage level. By isolating the batteries when the engine is off, it prevents the auxiliary load from draining the starter battery, thereby maintaining vehicle or vessel reliability.
Advantages
This charge relay offers a reliable solution for high-current power management without the significant voltage drop associated with traditional diode isolators. Its automatic operation eliminates the need for manual switching or complex monitoring systems, providing a seamless charging experience. The compact and durable design is built to withstand demanding environments, ensuring long-term performance in automotive, marine, and off-grid solar setups. By facilitating intelligent charge distribution, it protects your electrical infrastructure and extends the lifespan of your battery banks.
Suitable for
Dual-battery systems in campervans and motorhomes
Marine electrical installations for engine and service batteries
Off-grid solar power systems requiring battery bank isolation
Emergency vehicles with auxiliary power requirements
When it may not be suitable
This relay is not intended for applications requiring manual override or complex programmable charging profiles that go beyond simple voltage-based switching. It may also be unsuitable for systems where the charging source voltage fluctuates significantly below the relay's activation threshold, as this could lead to frequent cycling.
Key specifications
Operating voltage: 12V or 24V DC
Maximum current rating: 120A
Automatic connection and disconnection based on voltage
Suitable for dual-battery configurations
Designed for automotive, marine, and off-grid use
How to use
Installation involves connecting the relay between the starter battery and the auxiliary battery bank. Ensure that appropriate gauge cabling is used to handle the 120A current capacity and that a suitable fuse is installed on both sides of the relay for circuit protection. Once connected, the relay monitors the voltage of the primary battery; when the voltage rises above the threshold, the relay closes to allow charging of the second battery. When the voltage drops, it opens to isolate the batteries.
What to consider before purchase
Verify that your charging system voltage matches the 12V/24V compatibility
Ensure your total load does not exceed the 120A continuous rating
Check the available space for mounting in a dry and ventilated area
Confirm that your battery chemistry is compatible with standard voltage-based relay switching
Usage recommendations
For optimal performance and safety, always install the relay in a location protected from moisture and extreme heat. Regularly inspect all electrical connections for signs of corrosion or looseness to maintain efficient power transfer throughout the system.
