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
Eric, 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.

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.

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.
