Was Return Amps Thanks Roy I usually leap then look, The customer has it already, I ran it yesterday, on AC couple into the standalone system, I learned a lot. But it ran, and I am working out some of the surprises I had. I am building up two inverter boards with the systems to control the excess battery charging. I hope that Endurance does not get mad at me. It appears to be very will built machine.
I am also trying to modify my Dyno to drive the machine, so I can do some
controlled testing.
BTW when the anemometer indicates wind is present, the motor runs to start the
blades, I was measuring up to 6400 watts surge. After it starts, it is
impressive the power output. I have another install but hope to return with
new parts on Wed of next week. I will keep all informed. And all ideas are
welcome and probably needed.

Darryl,
You are probably aware of this but the Endurance machines are 240
VAC induction machines.
I had asked about their policy on AC coupling their turbines for off
grid use and they were
less than enthusiastic.
You might want to touch base with Endurance Wind Power before
proceeding.

experience with Endurance other than to know it is a good
machine. Talking with Magnum today they informed me that
the MS 4XXX PAE inverter, combined with the ARC remote
control, and BMK battery monitoring kit can do enhanced
SOC control. Has anyone compared this with the Outback as
I have not used the PAE inverter yet, only the AE
inverter?

That is
a good question, I have not an answer, but of
course it should be based on the amp hour of
the battery bank, absorb charging voltage, and
of course the charging source in the case of
generators. Following Ron's advise start at
C/5 for SOC less than 50% then C/10 till about
70% SOC and then C/15 till 80% then C/20 to 90
%. the problem we have no way to set these
values, Perhaps Ron could give is a routine?
The closet to SOC charging is the Outback and
then the Magnum but both miss the goal.

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,

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.
