ommissioning

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. 

The inverter commissioning procedure is as follows:

•  Put the 

DC disconnect switch 

07

 in ON position. If there are two sep-

arate external disconnect switches (one for DC and the other for AC), 

first 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 first 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

 fields.

• 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.

- flashing, 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 verification 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

Vin < Vstart

Vin > Vstart

NOTE:  Before  proceeding  with 

commissioning, make sure you 

have carried out all the checks 

and  verifications  indicated  in  the 

section on preliminary checks.
