In terms of
equipment space and cost, noise, fuel consumption, maintenance, it
makes no sense to install an AC generator.
yachtsmen would agree that the most convenient AC power is supplied
through a good inverter. Here
you have AC power available at any time day or night without having
to start, warm-up and run the generator.
DC Marine Generator charges the batteries directly in the most
Using an AC
generator to charge batteries through either a battery charger or an
inverter will require a much longer run time due to the current
limitations of the battery charger or the inverter.
Polar's DC generator can produce significantly more charging
current than a typical AC generator system with a battery charger.
With a Polar DC generator and a properly sized battery bank
you can have all the AC power you want with very little engine run
capacity of Polar's DC generators is excellent for powering bow
The advantages of a
DC generator over an AC generator are:
Smaller in size
Much lower fuel
longer operational life.
operate and maintain.
There are two power range options, low speed and medium speed. Both options cost the same as they incorporate the same engine and model 6250 alternator. The difference between the
medium speed and low speed is that the stator
in the alternator is optimized for the speed range.
the Lombardini Model LDW 602 FOCS at low speeds of 1,500 to 2,200
RPM creates very little noise.
The slow speed also extends engine life.
Model 6250 Alternator is capable of delivering 2.5 kW to 5 kW at this low speed.
Operating the engine in the 2,200 to 3,000 RPM range increases power to the 5 kW to 6.5 kW.
