Victron Cyrix-ct 12-24-120 120A 12V-24V Intelligent Battery Combiner

Please note that this product is available on a 1-2 week lead time.

Some battery combiners (also called voltage-controlled relay, or split charge relay) will disconnect a battery in case of a short but high amperage load. A battery combiner also may fail to connect a large but discharged battery bank because the DC voltage immediately drops below the disengage value once the batteries are connected. The software of the Cyrix-ct 12/24 does more than simply connect and disconnect based on battery voltage and with a fixed time delay. The Cyrix-ct 12/24 looks at the general trend (voltage increasing or decreasing) and reverses a previous action only if the trend has reversed during a certain period. The time delay depends on the voltage deviation from the trend.
