Q & A


Can an Electrolux travel pack (240v generator) be retrofitted to any boat, space permitting, and what is the typical cost of same, with fitting?

WW says:

The Travel power pack can be fitted to any engine with sufficient power to drive it. It will need an extra pulley fitted to the crankshaft, unless there is already a double pulley with a spare slot. It consists of a dedicated alternator with a special cable that connects it to the silver electronics box. Ideally this should be housed inside the cabin, with the cable routed to the generator.
The system will provide up to 16A, the power being dependent on engine rpm. Since the output sine wave is generated by the electronics, the frequency is independent of engine speed.
Under full load the unit will take 5.5kW from the engine, and needs to be properly installed. The mains output should be connected to the boat system with the usual precautions, including a means to ensure that two sources of mains electricity cannot be connected together; if in doubt consult a suitably qualified electrician.

I think they are around £3500 new plus VAT and the engine fittings. I know of S/H sets for around £1400.

If you are looking for a supply of 230-volt power on the boat, you might consider the other alternative which is a large inverter. This has several advantages.
For large loads like a washing machine or vacuum cleaner, you run the engine while using them so that most of the power is being supplied to the inverter by the alternator. If you do this while cruising and need to go through a lock, the battery bank supplies the inverter temporarily so there is no reduction in power while the engine is idling. When you get through the lock, the alternator takes over again and tops up the batteries at the same time.
Also, when you switch the engine off, the inverter can still be used for smaller loads, unlike the Travel power which only supplies power when the engine is running.
If the boat already has a large enough inverter, the cost is nil but, even if you need to fit a bigger one, the cost of this is likely to be less than for a Travel power unit.

Thanks for that answer, would you have any idea how much such a system would cost? I' m only after a ballpark figure.
