3.5.3 DC Input (PV) Connection

When installation, it must use the equipped DC terminals to avoid inverter damage.

It is recommended to use independent switch for each PV input, and before connecting, the
switches must be off. We suggest to use the special DC switch (rated voltage is 600V, rated
current is more than 20A).

Switch off the DC switch and external DC switches before connecting the PV array.

Ensure that the connection between PV array and the inverter at positive pole and negative pole
is correctly.

The DC input voltage should be less than the max. input voltage of the inverter.

It's forbidden to connect the grounding wire with positive pole or negative pole of PV array, or it
will lead to inverter damage.
Use the equipped PV connector and metal terminal to connect the PV input. The PV connecter
includes positive connecter and negative connector, they match the corresponding positive metal
terminal and negative terminal, corresponding procedure as follows.
