<p class=MsoNormal><span style='color:#1F497D'>AFRA is a setting that is used when
the SI is in an off-grid situation (can be grid tied, just that the grid is not
available). If there is a generator that is providing power at a higher
frequency, when the Sunny Island disconnects from the gen, it will lower the
frequency (below 60Hz), to adjust clocks for the higher Hz that the gen was
providing.<o:p></o:p></span></p>
