48V 35A Integrated Onboard Power System for Electric Boats

All-in-One Power Intelligence
The MultiPlus-II is a sophisticated power hub that intelligently integrates a 48V pure sine wave inverter, a 35A high-efficiency battery charger, and a 32A high-speed AC transfer switch. By combining these functions into a single unit, it minimizes cabling, simplifies troubleshooting, and offers a compact footprint—essential for optimizing space on any vessel.

The “CHARGE” Management Advantage
Go beyond simple charging with the integrated CHARGE power management system. Unlike traditional chargers, it monitors real-time power consumption and dynamically redistributes energy where it is needed most. This advanced system also serves as an emergency start solution and a cycle charger, all without requiring complex wiring or modifications to your alternator that might void its warranty.

Built for the Harsh Marine Environment (IP67)
Engineered for ultimate durability, the charger features a fully sealed, die-cast aluminum enclosure rated at IP66/IP67. This protects sensitive internal components from salt spray, dust, and heavy vibration.

  • Comprehensive Protection:Includes reverse polarity detection, no-load protection, short circuit safeguards, and a built-in thermal sensor for automatic recovery after overload events.
  • Precision Control:Features a digital DC voltmeter for 3-battery bank sensing, an adjustable PT charge voltage dial, and an integrated AC master circuit breaker for total input control.

Optimized Charging for Lithium & Lead-Acid
Electric propulsion relies on precision energy management. Our 4-stage adaptive charging profile ensures your batteries—whether high-performance Lithium or traditional Lead-Acid—are charged quickly and safely to maximize their cycle life.

  • Lithium Optimized:Specifically designed to handle the high-efficiency requirements of modern lithium chemistries to prevent overcharging and ensure long-term reliability.

Smart Connectivity: CANBUS Optional
The optional CAN bus interface allows for seamless communication with your Battery Management System (BMS).

  • Pre-Configurable:Setup is simplified by pre-loading battery chemistry, cell count, and Ah ratings.
  • Data-Driven Efficiency:Select pre-loaded charging algorithms at the touch of a button and utilize charge cycle data analysis to improve overall machine productivity and performance.

Powering the Future of Electric Boating
Whether you are calculating your range in kilowatt-hours (kWh) or monitoring your amp-hours (Ah), this system provides the reliability you need to stay on the water longer. It is the most robust size-to-power ratio solution on the market, ensuring your electric boat runs smoothly, efficiently, and safely.
