5 3 Connecting the PV Strings.
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, .
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 its permitted range.
The maximum short circuit current of each PV string must be always lower than or equal
to its permitted range.
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 the inverter the positive or negative terminals of,
PV strings cannot be connected with short circuit.
