We are readying our USA boat to cross over to the EU. I have decided to install an isolation autotransformer to step 230v 50 Hz shore power down to the 120v range and to improve the boat's galvanic isolation/protection. The transformer output, however, will still be 50 Hz. Our Quattro 12/5000/220-2x100 120v operates on both 50 and 60 Hz frequencies, but I cannot tell from the owner's manual whether it will convert EU 50 Hz to 60 Hz so we can run our 60 Hz A/C and other consumers on EU shore power. I assume the Quattro must be set to use shore power only to charge our batteries and then invert 12v DC to 120v 60 Hz for use on board. Please advise if this is not the case. Also, are there any PowerControl, PowerAssist, DIP switch or other settings that ensure 50 Hz current is used only to charge the batteries and is not distributed to our applicances, etc.?
