APsystems Microinverter QT2-208 Installation Manual 10
4. APsystems Microinverter System Installation
Install the microinverters (including DC and AC connectors) under the PV modules to
avoid direct exposure to rain, UV or other harmful weather events. Allow a minimum of
1.5 cm (3/4’’) below and above the casing of the microinverter to allow proper air flow.
The racking must be properly grounded as per local electrical code.
4.3.4 Step 4 - Ground the system
There're 2 ways to ground the QT2-208 series microinverters.
1. By grounding washer attached.
After the microinverters and racking are reliably installed, the microinverter's grounding
washer can connect to the racking to ensure proper earthing.
2. By grounding copper wire.
Fix the grounding copper wire by the grounding lug.
