At the heart of their power system two 3kW Quattro Inverter/Chargers provide 230VAC to domestic appliances from the boat’s 12VDC battery storage. Their Quattro’s have a 120A charging ability which makes short work of recharging their impressive 900Ah battery bank from generator. On board the catamaran, four charging methods are available: There is a 1kWp solar array with multiple MPPT solar charge controllers to maximise power harvest. Two engine-driven high power smart alternators are provided with two BuckBoost DC-DC converters which accept a wide range of alternator output voltages for conversion to a stable battery-charging voltage at 12V or 24V. There is an AC generator which can be started manually - or automatically by a relay which is tripped whenever the battery bank falls below 30% state-of-charge. Battery charging (and discharging) is controlled by a VE.Bus BMS battery management system.
