Most dishwashers clean dishes as well as the next; however, higher priced ones are generally quieter. Most models fit into a 24-inch-wide space under a kitchen counter top and are attached to a hot-water pipe, drain, and an electrical line. They can have a gravity drain or be fitted with a drain pump.
The dishwasher should be AC and therefore has an impact on requirements for a DC-AC inverter. Dishwashers are energy rated in kWh/y, typically 700-850. They draw around 9 A or more when running, depending on the features. (See [[ElectricalCapacityAC]]).
Check the water pressure requirements, typically 100-145 psi, and make sure you have enough pressure in the galley.
