EXIT NEXT nonGT MODE

The default value is nonGT or non-grid-tied. Select GT mode if you have a GVFX or GTFX inverter, MATE and HUB connected to the MX60. Selecting GT estab- lishes the proper grid-tie mode communications between the G-series FX and the MX60.

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. Press the <NEXT> soft key to view the Absorb Time Limits screen
