![]() Consider hydraulic alternatives for some high loads - eg davit/crane, windlass, bow thruster. Put a 5000W inverter in if you anticipate a lot of simultaneous high loads, otherwise 3000W will be enough for washer or dryer,microwave etc. I have over 1800W of solar panels, a 200A alternator on each engine and a large bank of Odyssey PC 1800 batteries that can take high charge rates. I have a 50ft boat and am in the final stages of a refit. You really don't want to be limiting yourself, or dependent on, docks with 50A outlets. ![]() That way shore power where ever you are can be used.īut think through your loads. You can of course use a frequency converter, which can have an isolation transformer built in, as part of your solution. ![]() I suggest picking the one where the boat is located most of the time, assuming that is where repairs/replacements (and additions) will also be done. Resistive loads can tolerate both frequencies but inductive loads (eg motors) will not be happy, and may fail. You need to choose either 60 Hz OR 50 Hz (with related voltages). Also I don't know which option would be best for setting the boat up for use in Europe for periods of time. The boat will have a 12KW generator installed and I don't know if that will be a factor in making the choice or not. I think the single 220VAC, 50A shore power cable would be best but I don't know enough to make a wise decision. The power requirements haven't been fully worked out but I know at lease 50 to 60 amps will be required. The boat will have a full array of air conditioners, refrigerators, freezers, washer/dryer etc. The 50 foot fiberglass hull is stripped down with all of the wiring and equipment removed and trashed so everything will be a new install. and then split off a separate 110VAC panel for small appliances and outlets or Option 2- two 110VAC, 30A shore power cables feeding two 110VAC electrical panels where there would not be any 220VAC equipment installed, which would you chose? The question is: If you could chose between Option 1- one 220VAC, 50A shore power cable feeding a 220VAC electrical panel for the heavy power users like air conditioners, water heaters, stoves, pumps, etc. First of all most of the time the boat will be in the U.S. Hello everyone, I have a question that I hope is simple for those of you in the know to help with.
