I would like to add a Inverter to our Amel 54. My plan is to change the Mastervolt 100 A to a Mastervolt Ultra Combo = charger/inverter. Change the 100A charger, because it has the bigger DC powerlines. Changing should be Easy, because most lines from Mastervolt charger connect the same way on the charger-inverter.
Or is it better to leave the charger as it is and add a simple Mastervolt inverter near to the batterie and feed the 220 Volt outlets.
