The "ROTO" range of Marine DC Gensets sets a new benchmark in high output and simple design.  This DC Generator is designed and built in Australia using the best possible Australian and international components.

Smaller yachts can now house a reliable source of DC energy to power DC appliances and charge their batteries. Motorboats can do away with larger, traditional AC generators and utilise inverters. This DC Genset also provides a supplement to existing power systems on larger boats, meaning larger gensets need not be run and batteries are always topped up when required.  Standard marine genset has a wet exhaust.  Unit can also be supplied ready for a dry stack exhaust system.

Noise:
Unhoused and unmuffled DC Genset 80Db at 4 metres (comparison unhoused Onan MDJE 240 volt AC Genset is 80Db at 4 metres with wet exhaust.)   In reality, if you have a sound insulated engine room, then you will only hear a light rumble far less than 69 Db

Output: Maximum output 60 amps at 12 volts and 30 amps at 24 volts.   Charging rate depends on existing battery state and air temperature.  Engine output set 30% below engine’s maximum capabilities for long life.

Exhaust Considerations:    The raw water pump will only operate when the engine is running. The waterlock muffler must be installed below the outlet of the stainless exhaust elbow to avoid any possibility of the raw water backing up into and damaging the engine.  If possible have a vertical loop in the hose after the muffler to remove any siphoning risk.   Sailing boats should always install an anti siphon valve after the muffler to ensure water is not sucked in via the exhaust hull fitting when the boat is heeled over.

AutoStart & AutoStop:  When house bank battery voltage falls to a set level engine will attempt to start 3 times.  Run time can be set for multiples of one hour or manually overridden.   With a known battery bank size and known charge output from the Genset, an accurate charging run time can be set.  

Ventilation:  The engine is aircooled and will require adequate ventilation. The exhaust system is water injection cooled.  The temperature will rise slightly in a hot engine room or on a hot day, however the Genset engine will also draw cool outside air into the compartment and expel this air overboard when running. The raw water pump keeps the exhaust cool. We also offer an air blower option that will resolve most engine room cabinet issues.

Basic Installation:  Your DC Genset will arrive fully assembled.  Simply place in position.  Secure engine mounts to the structure.  Attach exhaust hose to stainless exhaust elbow.   Position fuel pump, connect wiring with quick connect plugs  and connect fuel lines.  Position raw water pump, and connect wiring plugs.   Position and mount the relay box.  Connect wiring loom plugs.  Attach starter motor battery.   Run +ve and -ve charge wires from alternator to the battery bank to be charged.      Turn on ignition to activate fuel pump, bleed fuel line.  Engine will then start.
