PV Array Connection
Lethal voltage exists!
PV arrays produce electrical energy when exposed to light and thus can
create an electrical shock hazard.
Make sure that the PV impedance to the ground is proper before connecting
the PV array to the inverter.
6.3.1 PV Input Configuration
Inverter has a PV input area and a MPP tracker is equipped.
The following two requirements must be respected. Ignorance of them may
void any or all warranty rights.
The inverter internal cable connection cabinet does not equip any positive
or negative fuse. During system design, you can follow the local
regulations to configure or not configure the external fuse to the positive
and negative cables of the string.
Make sure the voltage of each PV array is less than 1000V at all times.
Irrevocable damage may follow if otherwise.
Make sure the max. short-circuit current of the DC side is within the
permissible range. Irrevocable damage may follow if otherwise.
To make full use of the DC input power, the PV string should be with a
homogenous structure: including the same type, the same number of PV
cells, identical tilt and identical orientation.
