Even if you have a gen-set on board, you can still put an inverter to good use. Use the gen-set for the larger, long-running AC loads and bring the inverter into service for the smaller intermittent loads when you would prefer some peace and quiet.

Dockside power is convenient, but it is a major drawback for most cruising sailors – it is only available at the dock. New inverters are over 90% efficient when actively inverting and consume truly miniscule amounts of electricity in their idle mode.

An ideal gen-set would be lightweight, smooth, quiet, fuel-efficient, powerful, low-cost, reliable and fit in a spare locker. It’s best to determine what characteristics are most important for your situation before you shop around.

Balancing your electrical power supply in an acceptable manner is easy once you begin to take your role as energy manager seriously.

Increasing your electrical load or the length of your reserve capacity increases the total battery capacity required. Make sure that the total battery capacity you have calculated is suitable for your charging sources.
