Engineered hardware, designed to work in the field
Where the same problem keeps appearing across customers, we package our solution as a product — ready to deploy, class-approvable from day one.
Two products, both built on proven industrial control platforms: Tirfinn for multi-string battery installations, and Muirfinn for marine energy management.
Our Products
Engineered for real installations — built on class-approvable hardware, with cybersecurity considered across every interface from the outset.
Muirfinn
Marine Energy Management System
MOOR-FIN · Irish Gaelic: muir (sea) + finn (derived from energy). Our EMS for hybrid and battery-electric vessels.
- Reduce total cost of ownership — optimised dispatch across batteries, generators and shore power
- Power quality & condition monitoring built in — IEC 61000-4-30 Class A, using your instrumentation or ours
- Automatic compliance reporting — MRV, FuelEU, IMO DCS & CII, signed and timestamped
- No rip-and-replace — sits above the existing PMS, class-approvable from day one
Tirfinn
Array Management Unit
TIR-FIN · Irish Gaelic: tír (land) + finn (derived from energy). A battery supervisory controller for multi-string installations — built on Bachmann industrial control hardware.
- Independent safety protection — hard-wired emergency disconnect, overcharge and gas-triggered disconnection
- Coordinated fault handling — deterministic alarm, load-reduction and disconnection sequencing
- Environmental & fire-gas interfacing — ventilation, gas detection, suppression in the right order
- Event logging & role-based access — every event timestamped, cybersecurity designed in
