Re: [RE-wrenches] SW AGS
Jay, Stop absorb was enabled but that wasn't the problem. His batteries were shot. Eric, sorry I couldn't call. My cell phone died. But we figured out the problem. Seems like his system is working fine except for his 48v bank of expensive paper weights. Because he's still getting some Ah out of his industrial bank I put him on a daily EQ regime to see if we can breathe some life back into his batteries. I figured it's worth a shot and he'll learn more about battery maintenance along the way. Thanks guys!

Re: [RE-wrenches] SW AGS...or is it?
Jay,
To me, that sounds like the most logical answer.
By the way, it IS an XW after all...whodathot?

This will stop the AGS when the battery volts reach absorb setpoint.

I read through the archives on the XW AGS thread but have a query on
behalf of a customer with an SW AGS issue. I'm heading out to the remote site
tomorrow and would like, if possible, to show up knowing what I might be up
against.
The customer recently replaced his AGS for his two SW 6048s and then
upgraded his firmware a week later. He reported that his problem with the AGS
began after firmware upgrade. Here's the particular issue:
AGS will try to start the 15.8kW Multi-Quip genny due to low battery
voltage (event 306 DCV start). After about 5 minutes the AGS will stop the
genny due to battery absorption level reached (event 313 ABS stop). The AGS
will go through this event 306/313 cycle on and off until the homeowner shuts
down the AGS. To me this sounds like bad batteries. But, the homeowner says
this cycling does not occur when he manually starts the generator. This doesn't
sound like a complicated problem but so far I'm unfamiliar with the SW AGS. So,

Part of the XW/SW confusion is that there has never been an
SW6048. There were only the SW4048 and SW5548. The XW is available
as XW4048 and XW6048. At this point it's not clear which you're
dealing with here, given that Eric appears to have talked with
your customer.

SW AGS
Hi Eric,
Sounded like bad batteries to
me also (I think he called in this AM). He has (2) XW6048
units that are
capable of 200ADC between them,
and he also has 1260Ah of flooded capacity. DC Start V is set
for 46.5V, so if we assume he was close to 50%
discharge (depending on load),
it should take almost 2 hours to reach the bulk voltage (80%
replaced). His batteries were ramping up to bulk
in just a couple of minutes,
meaning the batteries were not absorbing the charge. I have
heard varying opinions on the symptoms of sulfation,
but it does sound like a
battery issue (5 yrs old). He was advised to equalize to try
and recover them (he has never done this), or replace them.
Rgds,

I read through the archives on the
XW AGS thread but have a query on behalf of a customer with an
SW AGS issue. I'm heading out to the remote site tomorrow and
would like, if possible, to show up knowing what I might be up
against.
The customer recently replaced his
AGS for his two SW 6048s and then upgraded his firmware a week
later. He reported that his problem with the AGS began after
firmware upgrade. Here's the particular issue:
Re: [RE-wrenches] SW AGS
HI Eric, Sounds like the "stop absorb" might have been enabled. This will stop the AGS when the battery volts reach absorb setpoint. But has no impact if starting the generator manually. jay peltz power > Sounds like you talked to the right guy, that's his info...except that he > has, according to what he told me, an SW not an XW.
