DC/AC Disconnect Switch

Figure 4-1 DC/AC Disconnect Switch Positions

In an installation with multiple GT Inverters, special commissioning procedures
must be followed in order to safely determine if any DC wiring problems exist.
Important:
Before performing this procedure, all inverters should be off, with the
DC/AC disconnect switch in the OFF position.
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.
