The "ROTO" range of Marine AC Gensets sets a new benchmark in high output and simple design.  Designed and built in Australia using the best possible Australian and international components.

We now have five years of these gensets in the marine marketplace.  Their reliability from a warranty and service perspective has been excellent.

Smaller Boats can now house a reliable source of AC power at an affordable price.   Motorboats no longer need to run larger gensets for their low load requirements. 

A new feature is the Air Charge Cooling system for the 5Kva genset reducing expelled heat from the generator to room temperature.  A 316 stainless wet exhaust elbow combines exhaust fumes with water prior to the waterlift muffler.  There is minimal latent heat build up from this motor thanks to the airflow, wet exhaust and air cooling system.

Units are now installed over the past 5 years are in Melbourne, Paynesville Vic, Sydney & Townsville. Melbourne, Cairns, New Zealand, Malaysia, Canada, Perth and a bunch of other locations.  Including many yachts of no fixed address!!!

If you want a simple, reliable generator for your boat with all the safety features, consider the Roto genset.   A Roto Genset will heat your water, charge your batteries, cook your toast, run the hotplate  and boil your kettle without fuss.

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.)   70 DB in non insulated cabin approximately 3 metres from engine.  If you have a sound insulated engine room, the noise from this generator without will be around 65-67db.  These test results are an indication only.

Output: Rate for Maximum continuous output is 3Kva or 5kva.   

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.

Ventilation: The Roto Genset will require adequate engine room ventilation. The exhaust system is also water injection cooled. This makes the genset ideal for smaller engine room compartments.  We also offer an electric air blower option to circulate new air into the engine compartment.

Basic Installation:  Your AC 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.       Turn on ignition to activate fuel pump, bleed fuel line.  Engine will then start.

Floor Space Required for mounting  cm:  3 Kva: 64L x 46W x 54H.    5 Kva: 70L x 50W x 60H.

240 Volt connections:  The AC Genset must be connected to the electrical system of your boat by a licensed electrician.  We do not provide any 240 volt distribution products and you will need to acquire these separately and have them installed by a person licensed to do so.
