Grounding

A protective earth (PE) terminal is equipped at the side of the inverter. Please be sure to connect this PE
terminal to the PE bar for reliable grounding. AWG 10 or 12 yellow green lines are recommended.
WARNING
CAUTION
Notes: Australia uses the TN-C-S earthing system which requires the neutral to be connected/bonded to the
earth to create a MEN (Multiple Earth Neutral) system:

The inverter must be grounded; otherwise, there may be electric shock risk.
If the positive pole or negative pole of the PV array is required to be
grounded, then the inverter output (to AC grid) must be isolated by
transformer in accordance with IEC62109-1, -2 standards.
