Step 3: Connecting MicroGTs to the PV Module

Use Figure 6 when connecting the DC cables from the PV modules to

the MicroGT 500 inverters.

Note: Upon connecting the DC cables, the MicroGT 500 inverter's LED

(on bottom of unit) should immediately blink red, then green three

times—indicating that the MicroGT inverter is functioning correctly.

This test function starts and ends within 5 seconds of plugging in the

unit, so pay careful attention to these lights when connecting the DC

cables. This only occurs when DC voltage is ﬁ rst applied. The LED will

not ﬂ ash when the second panel is corrected.

WARNING: Ensure that all AC and DC wiring is correct.

Check that none of the AC and DC wires are pinched or

damaged. Be sure all the junction boxes are properly closed.

Each MicroGT 500 inverter comes with a ground clamp that can

accommodate a single #6 AWG (13.3 mm

(21.1 mm

) solid conductor. Check your local electrical code for

grounding conductor sizing requirements.

Note: If you used grounding washers (WEEB) to ground the MicroGT

500's chassis to the PV racking—per Note in Step 2—skip this step.

1. Connect the grounding electrode conductor to the MicroGT 500

inverter ground clamp (Figure 7).

Note: The AC output neutral is not bonded to ground inside the

MicroGT 500 inverter.
