[RE-wrenches] Charging with Outback

William,

I believe that I recently noticed the same behavior with the global 
equalize.  It was overcast, and the MX 60 was bulk charging at about 3 
amps.  After initiating a global equalize from the Mate, I noticed that 
the MX 60 displayed Vbat > Absorb, then after a couple maybe three 
minutes it would go into the equalizing mode.  A couple minutes later, 
the MX 60 would sweep, display Vbat > Absorb.  And repeat ....  It was 
"off task" more than on.  Not very efficient. A C40 would have 
contributed more to the equalization.  Outback tech support said this 
was normal.

When you are only getting 3-amps into a 400-amphour battery, the solar 
system contribution is negligible anyway.  None-the-less, poor 
performance is not expected from first rate gear.
