[PUP] Arild and the design build "thing"

[Alan]

Alan,

How "huge" are those alternators and can you disengage them when not needed?

Also, how does the heat of the engine room affect them?

The AC power on board will be 220V/230V for all high power equipment.

The alternators are a pair of Balmar Series 98 24v 170 amp  alternators
running in tandem to provide the power.  At 150 Amps output, each alternator
delivers 4.1kW or 8280 watts total for both.  Even when the inverters are
full loaded there is a reserve of 2.8kW for charging batteries.  The tandem
alternators are powered by the 30 hp Kubota wing engine that will double as
a generator when needed.

An identical pair of Balmar alternators are run from the main engine, so the
"generator" is not needed while underway.

Fully loaded, the alternators will require 12 hp and the regulator -- as I
understand it -- reduces the load with reductions in power requirements,
although they are not disengaged.

My engine room is pretty well ventilated so I don't think heat is a problem
and the alternators are designed, obviously, to be used in an ER environment
