Commissioning
Do not place objects of any kind on the inverter during operation!
Do not touch the heatsink while the inverter is operating!
Some parts may be very hot and cause burns.
NOTE: Before proceeding with commissioning, make sure you have carried out all the checks
and verications indicated in the section on preliminary checks.
The inverter commissioning procedure is as follows:
• Put the AC+DC disconnect switch in ON position. If there are two sep-
arate external disconnect switches (one for DC and the other for AC),
rst close the AC disconnect switch and then the DC disconnect switch.
There is no order of priority for opening the disconnect switches.
• When the inverter has power, the rst check performed is the one rela-
ting to the input voltage:
- If the DC input voltage is lower than the Vstart voltage (voltage required
to begin the inverter’s grid connection) the b14 icon remains off and the
“Waiting for the sun” message is displayed b10.
- If the DC input voltage is higher than the Vstart voltage the b14 icon is
displayed and the inverter goes to the next stage of the controls.
In both cases the voltage levels and input current are displayed in the
b15 and b16 elds.
• The inverter performs a control of grid parameters. The b22 icon, which
represents the grid distribution, can have different statuses:
- Not present, if the mains voltage results as absent.
- ashing, if the mains voltage is present but outside the parameters dic-
tated by the standard of the country of installation.
- Turns on, if the mains voltage is present and within the parameters dic-
tated by the standard of the country of installation. In this condition, the
inverter starts the sequence of grid connection.
This verication can take several minutes (from a minimum of 30 se-
conds up to several minutes), depending on grid conditions and settings
relative to the standard of the country
