NOTICE

With several inverters connected it must be checked that the installation is carried

out on all the follower inverters.

• Look at the displayed menu and the LEDs: It is not carried out correctly if the

installation menu is still displayed and/or the green LED is not lit and the yellow

and red LEDs are lit.

• Check that the connection of the CAN cables are correct, that the AC and DC

switches are ON and that the voltages are >184 V

, and >230 V

and there is

greater than 7 W

of power

• If the Start Up phase is correctly carried out the inverters are ready to use. They

are fully automatic during normal operation, and no manual control is necessary

for feeding power into the grid.

The ‘Warning’ box is displayed if an error occurred during installation:

Warning Box

Errors:

1. No communication

2. Wrong grid settings

• Check the LEDs on the inverters. If the yellow and reds are lit check that the installation is

correctly performed and that the grid settings are correctly set.

• If the Start Installation - screen is still shown, run through the installation process on the

inverter.

5.3. Self Test for Italy

The Self Test function is only valid for Italy. It tests the inverters’ grid monitoring function of

voltage and frequency. The inverter carries out four test sequences, which together takes

approximately 2 minutes.

The self-test changes the trip values for the voltage and frequency to the current grid

levels to determine:

• Whether the threshold equals the actual measured grid values.

• Whether the inverter is triggered to disconnect from the grid by these limits.
