Power Sources

This course deals with 230V on the boat, including shore power, solar panels, and wind generator.


You will learn about safety around general use and work with shore power. 


Did you know, for example, that you should always connect the 230V cable in the boat first and then on land? It can be life-threatening if you are so unlucky to fall into the water with an attached cable.


The special requirements for 230V installations on the boat are reviewed. If, for example, you have other 230V equipment than a double insulated charger onboard, there is a requirement that there must be an electrical panel with an HPFI relay. 


Also, the course goes into detail with requirements and good advice for cable types, connectors, connections, etc.


You will also learn about inverters and connecting these. An inverter converts 12V or 24V from the battery bank to 230V. The course covers how to use a converter and the difference between good and less good quality inverters. It also covers what to be aware of when choosing an inverter and how they are connected correctly.


Finally, the course reviews solar panels and wind generators. Here the difference between the types, efficiency, installation, connection of several panels, and regulations are explained.
