Marine Power Inverter for Lithium Battery Energy Storage Systems (CCS Approved)

Marine Power Inverterfor Lithium Battery Energy Storage Systems (CCS Approved) Advantages of Power Frequency Isolation Architecture
Safety Isolation Design: Achieves electrical isolation between input and output via 50Hz/60Hz power frequency transformers, blocking direct pathways between DC and AC sides. Effectively suppresses common-mode noise and mitigates ground fault risks, meeting stringent electromagnetic compatibility (EMC) requirements for marine equipment.
Enhanced Surge Resistance: Utilising wound transformers with a wide input voltage range (DC 48-900V compatible with lithium battery systems), it withstands 1.5 times rated current transient surges. This accommodates dynamic high-power load demands during vessel operations, such as motor starts and anchor winch operations.

Lithium Battery Energy Storage System Compatibility
Intelligent Pre-charge Circuit Control: Incorporates a thyristor-based pre-charge module. During inverter startup, current-limiting resistors pre-charge filter capacitors, preventing surge currents from damaging the lithium battery BMS system during direct grid connection and extending battery pack cycle life.
Intelligent Charge/Discharge Management: Supports CAN/RS485 communication protocols for integration with lithium battery management systems (BMS). Enables dynamic power regulation during charging/discharging, SOC monitoring, and coordinated fault protection to ensure efficient and secure energy storage operation.

CCS Certification Assurance
Certified through CCS type testing, encompassing comprehensive evaluations including insulation withstand voltage, temperature rise control, ingress protection rating (IP23), surge suppression, and salt spray corrosion. Meets compliance requirements for diverse applications including seagoing vessels, inland waterway vessels, and offshore platforms.
