As the % of full charge
is related to the of degree
absorption
& gravity [the denser & more
charged acid descending, and lighter
acid rising]
@ what point in the absorption would
be prudent to stop charging?
I used to cut off the
charge on the Trace SW series at 12
“return
amps”, VS. the factory default I
think was at 5 amps. This has &
continues to work well but I never
had anyone really answer this
function
clearly.
Is there a battery
manufacturer or wrench that would
care to comment on the:
The minimum “Return”
amps to disconnect for a “full”
charge?
OR
The time required per
100 AHR after reaching the
Absorption
point setting for the mix to occur?
I realize that battery
construction, battery condition, age
and temperature and the current
power usage will also play into this
factor and
it may not be a simple answer.

Allen,
Can I infer that if you are
shutting off the gen before charge
rates drop in absorption that you
are
running only briefly in the absorb
phase? Or do your charge currents
remain
high through out an extended
absortion phase?
Perhaps you have plenty of PV
which you rely upon to bring the
batteries up through the absorption
phase,
once the gen is shut off.
I would be interest to learn
more
about your approach to this.
Thanks,
Mark

Propane Generator, Dual Outback
Inverters
The Onan RS20000 shown in the
generators article in HP
131 page 98 has performed flawlessly
as backup support to an Outback
quad-stack
of VFX3648s. Differences, however, are
that this 20kW gennie charges four
inverters, rather than two; the
elevation is 6,600 feet for about a
20% output
deration; there are no huge loads
above charging draw; and the client is
aware
enough to shut it off before
absorption reduces the charge rate -
all different
conditions than you have described, as
the gennie is usually fully loaded and
running in balance.
Darryl is right about the amount of
words necessary.
