Custom Screens
Two custom screens are available. The inverter does not display them unless they
are configured using a computer connected to the RS-232 port inside the wiring
box. If programmed, the custom screens display as the fourth and fifth screens
during the startup sequence. They can also be viewed by tapping the unit during
normal operation and fault mode.
The first custom screen is intended for the home owner to display information
such as the name or location of the PV array associated with the inverter.
The second custom screen is intended for installers, who can configure the screen
to display, for example, contact information for service.
A PC graphical user interface that can be used for configuring custom screens is
available for download at www.xantrex.com.
Status Indicator Lights
The GT Inverter is equipped with two status indicator lights (LEDs) located below
the front panel LCD (Figure 5-2). These LEDs indicate the inverter’s current
status (Table 5-11) and assist in troubleshooting the performance of the unit.
Only one indicator light will be lit at any time.
The “ ” in these two screens (see Table 5-2 and Table 5-4)
indicates that the unit is derating its output power because the
inverter heat sink temperature is above 75° C (167° F).
The asterisk only appears when the power is actually being
limited by the inverter.
Indicates the GT Inverter is not producing power due to
insufficient solar energy during low light conditions in early
morning or late afternoon or when the PV array is in shade.
This screen flashes alternately with the Normal Operation
default screen.
