[RE-wrenches] Absolyte recovery

[mac Lewis]

Hi Chris,

I suspect that the charger in the Apollo Inverter/Charger is undersized,
especially since all of the loads are -48V.  Conversely, the array is very
oversized and the controllers float most of the time.  The charge
controllers were working fine last I checked.  It's difficult to access the
site right now, it includes a 30 mile snow mobile ride.  We intended to put
a comprehensive remote monitoring system but it didn't get put in before
the snow came.  I want to get up there and help the system limp along until
snow melt when we can do a thorough assessment.
The generator guy went up there and someone had pulled the stop switch on
the genset.  The battery voltage was around 5V on a 48V bank.  Yikes!

  Thanks for the contact info.
