SW2512 and pump problems [RE-wrenches]

Wrenches,
I have a customer with a SW2512, 1400AH battery. Every time pump comes on,
system browns out enough to cause computer and TV problems (crashes and
resets).  Pump is 1/3 HP 115 VAC two wire sub pump, approximately one year
old.  Pump runs OK.  Well is not deep, maybe 40 feet.  Even browns out with
open discharge from pump.  Any suggestions?  This is the first two wire pump I
have seen on a SW inverter.  Is this the problem?  Any suggestions would be
appreciated.

More system info:
Batteries one year old, 2/0 interconnects, 4/0 inverter cables.  DC175.
E-meter.  8 kW genset.
Brownout is momentary but very noticeable, even with minimal other loads (<20A
DC)

Thanks
