Depending on th etype of inverter, you may experience surging when using mtorized appliances. This is due to the inverter's output being square wave instead of pure sine wave like shoreside AC. Also, a cautionary word is in order to all who are around your boat. AC voltages can kill, and when used in a marine environment become especially hazardous. Most inverters have very large capacitors which can release a large amount of current and generate an electrical shock even after DC power is removed. Always allow sufficient time for th inverter to discharge before disconnecting the DC wires for service or removal.
