120 Volt AC System

This will be a pretty short post as it is a pretty straight forward system.

For boats that are utilizing US small appliances, there is a separate Victron inverter in the basement that converts 24 Volt DC power from the battery bank into 120 Volt 60 cycle AC power. Note that this inverter does not provide any charging at all. Its sole function is to provide up to 3000 watts of 60 cycle power. The rest of the power is provided to US style outlets scattered around the boat.

Just a note – the auto transformer next to the inverter (also Victron) is to power the Miele Speed Oven which requires two independent legs of 120 volt.

The 110 volt power panel is located below the 240 volt section on the main panel near the helm station.

The only major appliance on the boat that uses this power is the Fischer Paykel Dishwasher – the top of which is just visible under the Miele Speed Oven.

Interestingly enough, many of our small appliances are actually 230 volt 50 or 60 cycle. This includes such things as our coffee grinder, toaster and breadmaker. This actually makes good sense as our 240 volt inverters have substantially more capacity then the 120 volt inverter.

There are also two more small 120 volt 60 cycle inverters. One is located behind the main power panel and solely provides power to our navigation lap top and the 3 monitors at the helm. There is a second under the crew bunk in the aft cabin which supplies power to a small charger for the engine and genset starting battery. There is also a 24/12 volt DC converter for charging the engine and genset batteries as well, but more about that in a post on the 12 systems.
