Adopts FEVE anti-corrosion housing, 304 stainless steel terminals and IP67 waterproof rating. Passes 72-hour salt spray test, adapting to humid and corrosive marine and RV outdoor scenarios.
Real-time monitoring via Victron display/VRM/LILEAD display; full control over key parameters.
No downtime during replacement; maintains system stability; RS485 & CANBUS dual-protocol for wide compatibility.
Communicates with Victron system in real time to automatically adjust CCL and CVL parameters, optimizing battery safety and service life simultaneously.
Adjusts generator output via dry contact signal automatically. Unattended operation realizes intelligent marine energy allocation.
Reaction Time: 3 seconds to power off
Operation: System triggers → battery disconnects and shuts down
Benefit: Maximizes onboard electrical safety
