Jamie, On my Amel 54 we have the Mastervolt charger 100A and 40A. The Mastervolt 100A works with 50Hz and 60Hz, all 100 - 240 Volt. I will add next Year the Mastervolt combi charger and inverter ( Ultra combi 100A/3500 Watt ) - this includes also the solarcharger and I can connect all with the LAN (MasterView Easy). For 60 Hz countries I will use the charger and inverter in line to get 50 Hz. I use a galvanic separator for shorepower - just behind the shorepower-inlet. Wolfgang Weber SY ELISE AMEL 54 # 162
