Radar,
No. It wasn't an "outright outage" on the ac side. The station felt an ac dip for 50 cycles. There was a large phase to phase and phase to ground fault on a few 7kv feeders out in the field, and station power "felt" this.
The suspect string of batteries are scheduled to be load tested asap. My guess still is that they are fine. I suspect the charger, and the was it handles voltage flucuations on the input.
Thanks for everyones opinions. I'll let you know how things turn out. I have been wrong many times before.
