Figure3-29 External grounding connection

The grounding of the inverter and the lightning rod of the building that inverter installed cannot

be the same, the two need to be separated (as shown in Figure3-30), or, lightning stroke will

damage the inverter.

The grounding of the inverter should be directly connected to the grounding system, and the

impedance should be less than 20m

Ω

.

3.5.3 DC Input (PV) Connection

When installation, it must use the equipped DC terminals to avoid inverter damage.
