PV Array Grounding
Grounding conductor of PV panel brackets must be firmly connected to earth at PV
array side and inverter side and SP side. The sectional area of grounding conductor
should be equal to the sectional area of DC grounding conductor. The minimum wire
diameter is 10.0mm.
DC Grounding
Select the DC Grounding mode according to the local standard and use the PV
grounding terminal box and DC Grounding wires of the same specification.
Grounding Device
If the positive pole or the negative pole of PV array need to be grounded in the PV
system, the inverter output should be insulated by Isolation Transformer. Isolation
transformer must conform to IEC62109-1,-2 standard.
