Product Introduction
Integrated Marine Power Solution: Shore Power | Marine Lithium Battery | DC Distribution | Vessel Charging
1. Product Overview
This full closed-loop marine power portfolio covers four core product lines: port AMP shore power system, modular marine lithium energy storage, shipboard integrated DC distribution equipment, and AC/DC vessel charging devices. All products comply with IEC 80005, SOLAS, MARPOL and CCS classification standards, delivering unified power solutions for inland electric vessels, coastal ro-pax ferries, hybrid tugboats, container ships, cruise liners, offshore platforms and global port terminals.
The whole system forms a complete energy logic chain: Quayside Shore Power Supply → Vessel Charging Equipment → Modular Lithium Energy Storage → On-board DC Distribution & Propulsion Control. It avoids fragmented procurement from multiple suppliers, cuts engineering coordination costs, and fully satisfies IMO low-carbon, zero-emission navigation and port emission control regulations.
