Connecting The Pv Strings - PrimeVOLT PV 2KTL-S1/G2P User Manual

5.3 PV Connection
DANGER
PV modules generate electric energy when exposed to sunlight and can create an electric 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 PV 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 connecting or
disconnecting a string or a module in a string. Only after the inverter enters in shutdown mode,
maintenance of DC input power cables is allowed.
WARNING
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.
