Normal Operation Mode
The LCD on the GT Inverter is refreshed every two seconds, so all readings are
current to within two seconds. There is a default display available at all times, and
a series of additional screens that can be displayed by tapping the inverter front
panel to change the display.
Normal Operation
default display After the protection timer has completed its countdown and during normal
operation, the GT Inverter displays the normal operation message screen shown in
Table 5-2.
If there is sufficient energy from the PV array, the default screen is displayed
continuously while the system is operating normally. In a multiple unit system
with communications cables properly connected, the power and cumulative
energy values displayed are for the entire system.
During low light conditions when the GT Inverter cannot produce any power, the
Normal Operation default screen flashes alternately (every two seconds) with the
Insufficient Solar Energy screen (see Table 5-10, “Special Message Screens” on
page 5–10).
More screens for all
systems Besides the default normal operation display, more system information messages
can be viewed.
To view more Normal Operation information:
• Tap the front panel to advance the display to the next screen. Normal
operation screens shown in Table 5-3 are displayed in the order given, as you
tap successively on the unit. They are common to all GT Inverter systems, no
matter how many units are installed.
If you continue to tap the front panel, the LCD continues to cycle through all of
the available normal operation screens. Each screen is displayed for a maximum
of 30 seconds. If you do not tap again during that time period, the LCD backlight
turns off and the display reverts to the default system message screen.
