01

Smaller size,
better space utilization

H-Series is about two-thirds lighter and 50% smaller than its diesel counterpart, providing installation flexibility and maximizing payload and passenger space. The flat wire motor increases slot fill by 25% and increases power density.

02

Modular design,
custom solutions to suit your needs

The modular design enables manufacturers to easily extend the range and power by adding motors, controllers and batteries, and having more flexibility.

03

Boating IoT system,
smart and customizable

The boating IoT (ePropulsion Connectivity Service) can be customized and satisfy the customers’ needs of remote monitoring and integrated management.

04

Optimum performance,
pioneering technology

Equipped with pioneering permanent magnet motor technology, the H-Series delivers up to 2000 Nm maximum torque and delivers an impressive 96% efficiency, higher than the traditional 100 kW AC asynchronous motor.

05

High
Expandability

Different power combinations can be chosen according to different power and range requirements, which allows the H-Series to be more expandable.
