ADVANCED
The ADVANCED MENU allows ne-tuning of the MX60 operations including “Snooze” periods and
Maximum Power Point limits. In order of appearance, the following modes occur in the ADVANCED
Menu selections:
Snooze Mode Park Mpp (% Voc) MPP Range Limit % Voc Sweep Interval Vbatt
Calibration Low CutO MPPT Mode Absorb Time Limits Wakeup Mode
From the MAIN Menu, choose Advanced and press
the <GO> soft key.
The MX60 wakes up when an optimal amount of
open circuit voltage (Voc) is available. The Voc varies
with external conditions, primarily the weather and
time of day, which a ect solar panels. If the Voc is
insu cient, the MX60 enters “Snoozing” until either
a ve-minute (default) period passes or there is a 1.5
volt (default) increase in Voc at which point the MX60
reevaluates the Voc for recharging purposes. What
is the optimal amount? The MX60 tries to recharge
when the Voc is greater than the battery voltage by 2
volts, but voltage alone isn’t su cient. An array might
have a big increase in voltage rst thing in the morn-
ing— more than 2 volts di erence—but not enough
ampacity to recharge.
Snoozing also occurs if the recharging current does
not reach the user-selected cuto current set point in
the Lowcuto menu. Press the <MODE> soft key for
Snooze Mode options. Press the <NEXT> soft key for
the Park Mpp screen
NOTE: There are four Low Cuto options:
• <90% Voc—MX60 snoozes if Voc does not rise to greater than 90% of last measured Voc during a
full sweep
• <50% Voc—snoozes if Voc does not rise to greater than 50% of last measured Voc during a
full sweep
• <Lowcuto —default snooze mode, snoozes if initial sweep does not reach Low Cuto Amps
during a full sweep
• Disabled—no snoozing, MX60 will cycle on and o many times (not recommended due to
ongoing relay-clicking)
