5.3 DC Connection

PV modules generate electric energy when exposed to sunlight and can create
an electrical shock hazard. Therefore, when connecting the PV modules,
shield them with opaque cloth and ensure that DC switches are OFF.
To avoid electric shock, don't touch the charge part and connect the terminals carefully.
DANGER
Before connecting power cables,ensure the AC/DC switches are OFF.
When the inverter is grid-tied, it is not allowed to operate the PV strings ,
only allow after the inverter enters in shutdown mode.
PV modules connected in series in each PV string must be of the same specifications.
The maximum open-circuit voltage of each PV string must be always lower
than or equal to its permitted range.
The maximum short circuit current of each PV string must be always lower
WARNING
than or equal to its permitted range.
Ensure that the positive and negative terminals of each PV strings connected to the
inverter are correct.
The positive or negative terminals of PV strings can't be connected with short circuit.
The total output power of all PV strings can't exceed the maximum input power of the inverter.
The positive and negative terminals of PV modules can't connect to PE wire(GND) ,
otherwise, the inverter will be damaged.
Ensure that the voltage of each PV string doesn't exceed 1100V under any circumstances.
NOTICE
Input voltage ranges from 1000V to 1100V, the inverter in standby status.
When the voltage is restored to the operating voltage range 160V to 1000V of
the MPPT , the inverter returns to normal status.
