Jay,
To me, that sounds like the most logical answer.
By the way, it IS an XW after all...whodathot?
Eric, I'll give you a call when I get there. Thanks!

HI Chris,
Nope the SW had a pretty simple menu AGS wise.

Now there is a useful setting, just being a little sarcastic, this would be
hard to diagnose. Was that available on the SW’s AGS menu too?

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.

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. I'm assuming he's maybe at
50% capacity on his original 1260Ah bank based on everything he told me this
morning. He did say that his bank will last him through the night and that he
has some pretty hefty air conditioning loads. He also said he had equalized in
the past but not in the last 18 months. I'm just not convinced that his
batteries are shot. But all this battery talk may be beside the point if he's
not experiencing the same on/off cycling problem when he manually starts the
genny, right? That is, assuming the disco settings remain in effect regardless
of start mechanism. Thanks for indulging me tocayo.

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:
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,
I would greatly appreciate any insight you guys can offer me.
Thanks!!
