Starting the Inverter

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.
