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.
7.2 Mechanical check
Carry out the main mechanical checks to ensure the inverter is
waterproof as follows:
①
Make sure the inverter has been correctly mounted with wall
bracket.
②
Make sure the cover has been correctly mounted.
③
Make sure the communication cable and AC connector have
been correctly wired and tightened.
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.
