Uses high-performance lithium iron phosphate cells, reducing weight by 80% and saving 50% space compared to lead-acid batteries of the same capacity.
Supports up to 18 units in parallel, with a total capacity of up to 115 kWh, easily handling long off-grid power supply, providing more space onboard and longer sailing range.
Supports module hot-swapping without power off, enabling battery replacement while running and automatic load redistribution.
Simplifies system expansion and upgrades, reducing maintenance effort.
Real-time monitoring via Victron display: Individual cell voltage balancing status. Charge-discharge cycle count statistics. Battery temperature heatmap.
Supports VRM cloud platform remote monitoring: check battery status globally anytime, receive low battery/high temperature alarm notifications.
Deep support for Victron systems, intelligent coordinated charge and discharge management.
Seamless integration into NMEA2000 network via Victron Gateway, achieving full onboard energy data integration and status monitoring on one screen.
Built-in intelligent BMS management system offering comprehensive protection against overcharge, over-discharge, short circuit, and over-temperature.
One-touch master control, all battery statuses synchronized; switching on/off is as simple and convenient as turning on a light.
AI charging algorithm: real-time sensing of SOC, temperature, and health status, dynamically adjusting charging parameters to effectively extend battery life.
Linked monitoring with Victron devices; automatically switches to protection mode when abnormalities are detected to prevent sudden power outages.
Optional heating function automatically activates below 0°C without manual intervention, ensuring smooth charging even in harsh cold environments.
Sail confidently in cold weather without fear of low temperature challenges.
Built-in dry contact interface, factory default settings: automatically shuts down the generator when battery level exceeds 90%, automatically starts it when battery level drops below 20%, no manual intervention needed.
Dry contact parameters can be customized in batches before shipment to meet different vessel and system requirements.
