Low Cutoff sets the battery charger's lowest allow-
able current limit the MX60 will charge in MPPT
mode before stopping and returning to "Snoozing. "
The Low Cutoff is adjustable from .2 amps to 1 amp;
.6 amps is the default Low Cutoff current. Raising
this value will assist the MX60 in entering "Sleeping"
mode at night. Press the <+Amp> soft key to raise
this limit. When fi nished, press the <NEXT> soft key
to view the MPPT Mode screen.
This screen allows the user to choose one of these
modes:
• Auto Sweep MPPT Mode (the default and preferred
mode), which sweeps the PV upon wakeup and
then does mini Sweeps from that point on at the
selected Sweep Interval. If the sweep interval is set
at 0 minutes, the MX60 awakes every 1.5 hours and
does a full sweep. Auto Restart applies here as well
(see LOG2 Auto Restart, page 52).
• U-Pick % (Voc) MPPT mode operates the PV voltage
at a user-selected percentage of the Voc which is
displayed in the Park Mpp % Voc screen. U_Pick %
acquires a new Voc value every Sweep Interval. If
the mini-sweep interval is set to 0 minutes, a new
Voc may be acquired once every 1.5 hrs. depend-
ing on the Auto Restart setting (see LOG2 Auto
Restart, page 52). This is an alternative to the Auto
Sweep mode and may also be useful for micro-hy-
dro applications.
Press the <MODE> soft key to choose an MPPT
mode and the <nonGT> soft key if you have an Out-
Back G-series inverter system with a HUB and MATE.
