The Victron Energy Cyrix-i 24/48V-400A intelligent battery combiner is a microprocessor-controlled heavy-duty relay for 24V and 48V battery systems. It automatically connects battery banks in parallel for charging and disconnects them as voltage falls. With 400A continuous current, intelligent voltage-trend monitoring and virtually no voltage loss, it supports efficient high-current charging.
Bidirectional voltage sensing allows charging from either battery side, while four selectable switching profiles adapt operation to different systems. A 30-second emergency parallel function, remote monitoring microswitch and bicolour status LED add control for demanding dual-battery installations.
