I'm in planning phase for my boat power, I've arrived in the US with a European boat and I'm working on mitigating the 50/60hz issues. So I'm planning to install a quattro 230v 5k 24v inverter/charger (then later I'll tackle getting some 110v power out of it with an autotransformer maybe). My question is - when connected to shore power (230v 60hz here in the US), can I completely disable any shore power passthrough and purely use the shore power to charge my batteries with the charger side of the quattro? This way I won't push damaging 60hz to my otherwise 50hz devices onboard?
