2. Check the DC voltage values: make sure 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 generator’s insulation to ground with a
multimeter: make sure that insulation resistance to ground is
greater than 1MOhm.
5. Check the grid voltage: check that the grid voltage at the
point of connection of the inverter is within the permitted
range.
Danger to life due to the presence of DC-Voltage
Touching the live conductors can lead to lethal electric
shocks.
• Only touch the insulation of the PV array cables.
• Do not touch parts of the sub-structure and frame of the
PV array which isn’t grouned.
• Wear personal protective equipment such as insulating
gloves.
Danger to life due to the presence of AC-Voltage
Touching the live conductors can lead to lethal electric
shocks.
• Only touch the insulation of the AC cables.
• Wear personal protective equipment such as insulating
gloves.
