DANGER
PV Strings connection needs below prerequisites; otherwise, an
electrical shock can occur.
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.
Before connecting DC input power cables, ensure that the voltage on the DC side is within the
safe range and that the DC SWITCH on the inverter is OFF. Otherwise, high voltage may result
in electric shock.
When the inverter is grid-tied, it is not allowed to maintain DC input power cables, such as
connect or disconnect a string or a module in a string. Only after the inverter enters in shutdown
mode, it is allowable for preceding DC input power cables maintenance.
WARNING
Grounding the PV Strings needs below prerequisites; otherwise, a fire
can occur.
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 600
V DC.
The maximum short circuit current of each PV string must be always lower than or equal to 16 A.
The positive and negative terminals of PV modules must be connected to the positive and
negative DC input terminals of the
inverter
respectively.
During the installation of PV strings and
inverter
, the positive or negative terminals of
PV strings cannot be connected with short circuit.
