If the inverter is not equipped with a DC switch but this is mandatory in the
country of installation, install an external DC switch.
The following limit values at the DC input of the inverter must not be exceeded:
It is suggestiong that connecting eleven PV modules that have an IEC
61730 Class A rating in series as one PV input.
6.4.2 Connecting the PV Array
Danger to life due to lethal voltages!
Before connecting the PV array, ensure that the DC switch and AC breaker are
disconnect from the inverter. NEVER connect or disconnect the PV connectors
under load.
Make sure the maximum open circuit voltage(Voc) of each PV string is
less than the maximum input voltage of the inverter.
Check the design of the PV plant. The Max. open circuit voltage, which can
occur at solar panels temperature of -10℃, must not exceed the Max. input
voltage of the inverter.
Improper operation during the wiring process can cause fatal injury to operator or
unrecoverable damage to the inverter. Only qualified personnel can perform the
wiring work.
