Grounding
AC Grounding
The CPS Mini Central On-grid Solar Power Generating System must be connected to the AC grounding
conductor of the power distribution grid via the ground terminal (PE).
PV Grounding
The grounding conductor in the framework of the PV array must be connected to the PV grounding
conductor and the DC grounding conductor. The cross-section of the grounding conductor corresponds to
the cross-section of the largest conductor in the DC system.
DC Grounding Conductor
A DC grounding conductor may be required by the Authority Having Jurisdiction (AHJ). Use the terminal
block for the PV grounding conductor and DC grounding conductor.
Ground kit
If PV modules of the PV system require POSITIVE or NEGATIVE to connect to GROUND, the output of
On-grid Solar Power Generating System should connect to grid with an isolating transformer.
The connection method is below:
N of transformer should not be connected to PE.
