The last few amps in the bank are not important and take a lot of
generator time to put in.
I usually look at the volt/amp meter and when the amps go below 25 or so
I turn off the generator.
You could remove the 220 volt fan and install a 220 volt relay and when
the genset goes on the relay would close and the fan will go on.

On our SM, 302, June 2000 launch, now lived aboard for 18 months,we
that at sea we run the genset about every six hours for an hour to an
and a half on each occasion. Less when at anchor without autohelm, nav
lights radar etc.Our first batteries ( we have 420 amps) lasted two
since when I tend to recharge when we are down to 90% ( We found that
fridge cut out somewhere below 87% notwithstanding the fact that we
I find that the recharge quickly up to 99% but that those last few
amps,say the last 7, take for ever.
Does anyone know how important it is to always recharge to 100%?
The one thing I would suggest when running the genset is to check that
220v fan is working ( put your hand over the outlet in the cockpit
) Ours failed in the Caribean and the extra heat in the engine room was
appparently the reason why our 50 amp charger failed after 3 years, to
followed by the 30 amp one ten weeks later.This, despite the fact that
chargers have heat cut outs.The first failed in Guadeloupe and was
the knowledge of Pochon for a speedy repair.but both were repaired by
in Ecuador ( thank God for the third world--they still know how to fix
things there).He said he had never seen anything so hi tech and
such a small box--the last time he saw such a powerful gadget it was the
size and weight of his mother in law!
The cost of a new 220v fan ,one new 50 amp and two repairs was
and I don`t understand the need for the 220v fan. The two 24v fans are
more powerful,give you an element of redundancy, much cheaper and can be
sourced anywhere.Is there a good reason why they could not be wired up
come on with the genset just as they come on with the Volvo/Yanmar? Ian.
