System Design and Installation – Our electrical and engineering expertise enables us to design, supply and install AC or DC generators plus associated power distribution systems to cope with the power you need on board today.

Installation Reviews – Ensuring your generator is installed correctly is paramount to your warranty and the use of the machine. Installation requirements are very stringent, we are able to offer advice if you or an independent boat builder are installing the unit and we are available to undertake installation reviews.

Service and Repair – We can test, maintain and repair existing generators and offer a similar winterisation process to that for the vessel’s main engine(s).

Load-Bank Testing – We offer load-bank testing on generators and can provide full test results and video footage once the test has been completed. 

Configuring your PCB – It is very easy to find that someone onboard has incorrectly used your control panel, resulting in your generator not working, and not necessarily giving you a fault code. Each model of generator has an onboard PCB, which is configured to a particular setting before leaving the factory. Pushing control keys too many times will change this setting. If you think this might have happened to you, call us for assistance and we can provide detailed instructions on how to re-configure your set.
