between inverter and PV modules.
NOTE1: Please use 600Vdc/30A circuit breaker.
NOTE2: The overvoltage category of the PV input is II.
Please follow the steps below to implement PV module connection:
Step 1: Check the input voltage of PV array modules. The acceptable input voltage of the inverter
is 250Vdc-450Vdc (with rated load). This system is applied with two strings of PV array. Please
make sure that the maximum current load of each PV input connector is 13A.
Step 2: Disconnect the circuit breaker and switch off the DC switch.
Step 3: Assemble provided PV connectors with PV modules by the following steps.
Components for PV connectors and Tools:
Female connector housing
Female terminal
Male connector housing
Male terminal
Crimping tool and spanner
Prepare the cable and follow the connector assembly process:
Strip one cable 8 mm on both end sides and be careful NOT to nick
conductors.
Insert striped cable into female terminal and crimp female terminal as
shown below.
Insert assembled cable into female connector housing as shown below.
CAUTION: Exceeding the maximum input voltage can destroy the unit!! Check the
system before wire connection.
WARNING: Because this inverter is non-isolated, only three types of PV modules are
acceptable: single crystalline and poly crystalline with class A-rated and CIGS
modules.
To avoid any malfunction, do not connect any PV modules with possible current
leakage to the inverter. For example, grounded PV modules will cause current leakage
to the inverter. When using CIGS modules, please be sure NO grounding.
CAUTION: It’s requested to use PV junction box with surge protection. Otherwise, it
will cause damage on inverter when lightning occurs on PV modules.
