7 Commissioning
7.1 Electrical checks
Carry out the main electrical checks as follows:
①
Check the PE connection with a multimeter: check that the inverter’s exposed metal
surface has a ground connection.
②
Check the DC voltage values: check that the DC voltage of the strings does not
exceed the permitted limits.
③
Check the polarity of the DC voltage: make sure the DC voltage has the correct
polarity.
④
Check the PV array’s insulation to ground with a multimeter: make sure that the
insulation resistance to ground is greater than 1 MOhm.
Danger to life due to the presence of DC voltage
• Only touch the insulation of the PV array cables.
• Do not touch parts of the sub-structure and frame of PV array which
are not grouned.
• Wear personal protective equipment such as insulating gloves.
Risk of injury due to incorrect installation
We strongly recommend carrying out preliminary checks before
commissioning to avoid possible damage to the device caused by
faulty installation.
