Outback Power AC voltage fluctuation [RE-wrenches]

[John Raynes]

Jay and others,

There is a CAL function on the Mate.  Have you tried that?  I've had to 
use it several times.  It's on the last page of the ADV screens.  It 
has settings for VAC and battery.  I find its individual steps to be 
very coarse (about .4 volts for DC, can't remember for AC) but if 
you're far off that might help.

I can't say that it would do anything for the voltage fluctuations.  
But, maybe if the two inverters were way out of whack with respect to 
each other it might help, when the 2nd is switching in and out, who 
knows.

I'm finding the new Apollo T80s not be as accurate as I would like with 
regard to batt voltage and current, either.  I don't think that +/- 1% 
on battery voltage measurement cuts it when you're trying for tight 
coordination between various charging sources.  All of these devices 
should have fine-grained calibration adjustments, whether they be pots 
or digital adjustments from the operator screen.
