Starting the Inverter
4–4
975-0334-01-01
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.
4. After the input current has risen above 1 A, if the inverter is still operating
normally, switch off the inverter by turning the DC/AC disconnect switch to
the OFF position. Proceed to step 5.
If the inverter stops operating after the input current has risen above 1 A, turn
the unit off, remove DC power, and have a certified electrician or technician
inspect the ground fault protection fuse. If the fuse has blown, a DC wiring
problem may exist. Check all DC wiring to ensure that the unit is connected to
a single PV array.
5. Proceed to the next inverter and perform the same test. See Figure 4-2 for an
example of the recommended commissioning sequence.
