For operation convince and safety the inverter requires multi-stranded
,
wire and crimping terminals with a proper crimping tool before wiring
.
,
To avoid potential risk 125A / 400VAC overcurrent protection device is
recommend to add on the output terminal
.
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
.
