This is a combination 240 Power supply with all the features of the 24/1600  inverter as well as a 40A - 24 Vbattery changer.
The advantage of this unit is that to provides seamless power when switching between Generator power and Inverter power and at the same time when the generator is running, the batteries are being charged.
 
It gives priority to generator power and when the generator is switched off, power is maintained from the Batteries by the inbuilt 1600w 240 v inverter.
 
Nice unit and sized right for 1200A/H 24v houseboat battery systems.
