= AC Secondary System =
The boat's secondary electrical system is AC. The exact specification will be driven by the standards in the part of the world where you mainly operate and will source shore power and various appliances and tools. As much as possible minimize the use of AC, in part to reduce the size and cost of the inverter. Any large motors should be DC.
If you intend to operate globally you will need a voltage- and frequency-converting inverter. In North America electrical standards are 120-VAC 60 Hz single phase or 240-VAC 60 Hz double phase. Elsewhere most countries use the European standard of 230-VAC 50 HZ single phase. The frequency difference means motors will run at different speeds.
== Inverter/Charger ==
A combination inverter/charger is attached to the [[HouseBank|house bank]] for generating AC from the batteries when offshore, and/or charging the batteries from shore power when in port. Points to consider in an inverter/charger are:
* Peak power output
* Output current regulation
* Safety factor of 30%
* Frequency conversion
== Shore Power ==
* Use DC motors only
* Put AC motors on the inverter power only, not on direct shore power
* Install a voltage- and frequency-converting inverter/charger
