Starting up the GT Inverter
To start up the inverter:
1. Switch the DC/AC Disconnect switch to the ON position (see Figure 4-1).
2. Check the GT Inverter LCD. The startup screens (see Table 5-1 on page 5–3)
should appear for five seconds each, and then the “Reconnecting in sss
seconds” special screen (see Table 5-10 on page 5–9) will appear until the 305
second (default value) protection timer countdown is completed.
Commissioning Multiple Inverters
In an installation with multiple GT Inverters, special commissioning procedures
must be followed in order to safely determine if any DC wiring problems exist.
To commission multiple inverters:
1. Uncover the PV arrays and/or close the main DC disconnect switch, if one is
installed.
2. Start the first inverter by turning the DC/AC disconnect switch to the ON
position.
3. Wait for the input current to rise above 1 A.
This information is displayed on the Array Readings screen. To display the
Array Readings screen, tap the unit four times.
Figure 4-1 DC/AC Disconnect Switch Positions
DC/AC Disconnect Switch
Important:
Before performing this procedure, all inverters should be off, with the
DC/AC disconnect switch in the OFF position.
