Mantis
Reliable power for marinas, aquaculture and other offshore locations the grid can't reach.
Mantis is an integrated energy platform. It combines wave, solar and battery storage to provide a more consistent source of power where grid access is limited.
Mantis can provide marinas with a renewable energy source able to cope with increasing energy demand at berths and moorings. Our solution is simple, accessible and designed to respond to this need even where the grid is not available.
5 kW | 0.2–3 m | Wave + solar + battery | Built for arrays
Low impact
Quiet with minimal seabed infrastructure
Compact
More power from a smaller footprint
Scaleable
Designed to scale up to form arrays
Low maintenance
Modular, replaceable parts
More power. Less infrastructure.
Mantis delivers more power from a smaller footprint, with just one moving part. Modular, replaceable components keep maintenance and downtime low, while quiet operation and minimal seabed infrastructure reduce its impact on the marine environment.
Designed to Scale
Our devices are designed to grow with your power needs. Start with a single unit, then link multiple units together in arrays to supply larger loads or form a local micro-grid. The same approach works at every scale, so increasing generation is a matter of adding more units, not redesigning the wider system.

Charge time
Scales with wave conditions and battery size. As a guide: in moderate wave conditions (around 0.75m wave height, typical of a sheltered marina), a 5kW Mantis unit tops up a 110Ah leisure battery in about an hour. In calmer conditions (around 0.4m, typical of a more protected mooring), the same battery takes around 2 hours. Larger battery banks, like a 21kWh EV charging console, scale accordingly, from roughly a day in moderate waves to just over two days in calm conditions.
