Connecting the DC input power cables
Connect the 3PH 100KTL-136KTL-HV inverter to the photovoltaic strings using DC input power cables.
Select the input mode: the 3PH 100KTL-136KTL-HV inverter has 10-12 MPPTs, which can be set
independently or in parallel, depending on how the system was designed. The user can choose the
appropriate MPPT operating mode.
Independent mode (default):
If the strings are independent (e.g. installed on two separate flaps), the input model must be set to
“independent mode.”
Parallel mode:
If the strings are connected in parallel, the input mode must be set to “parallel mode.”
Note:
-
Connecting PV strings into inverter must following the below procedure. Otherwise, any faulty cause
by inappropriate operation will be including in the warranty case.
-
Ensure the maximum short circuit current of PV strings should less than the maximum inverter DC
current input.And three “DC switch” is in OFF position. Otherwise, it may cause high voltage and
electric shock.
-
Ensure PV array have good insulation condition in any time.
-
Ensure same PV string should have the same structure, including: same model, same number of
panels, same direction, same azimuth.
-
Ensure PV positive connector connect to inverter positive pole, negative conenctor connect to
inverter negative pole
-
Please use the connectors in the accessories bag. The damage cause by incorrect is not including in
the warranty.
