Figure 17 - Snooze Mode
Optimization Menus
Snooze Mode: Very early or very late in the day, when it is twilight, the resistance of the pan-
els are high. However, there may be enough open circuit panel voltage that the MX60 will want
to wake up and operate when there is not really enough power to do any charging. Instead of
waking and clicking and operating unnecessarily, the MX60 can try to "snooze" for a few min-
utes and ignore this Voc. There are moments in the MX60s operation where the MX60 can look
at the voltage rise time of the panels against the PV side capacitors and snooze if the panel
voltage did not rise to the last measured panel Voc. After enough light is shining on the panels,
the panel resistance goes down enough that the panel voltage rise time is fast and reaches the
last Voc quickly so it will come up and operate and not snooze at that point. The MX60 will
abort the snooze cycle early if the Panel voltage goes a small amount above the last measured
Voc. This is usually early in the morning when the Voc can be rising fairly quickly.
< 90 % Voc Snoozes if the panel voltage failed to rise to greater than 90 percent of the
last measured Voc during a short time interval. This is the default.
< 50 % Voc Snoozes if the panel voltage failed to rise to greater than 50 percent of the
last measured Voc during a short time interval.
< Lowcutoff Snoozes if the initial sweep did not reach the Low Cutoff current.
Not applicable in U_Pick % Voc mode.
Disabled No Snoozing will occur
