Icons status
Operating state
Firmware programming
The inverter firmware is being programmed
Night mode (inverter automatically switches off)
The inverter is in night time switch-off mode (input voltage less than 70% of the set start-up voltage).
Inverter initialisation
This is a transitional state due to the verification of the operating conditions. During this stage the inverter checks that the conditions for
connecting to the grid are met.
The inverter is connected and feeds power into the grid
Normal operation. During this stage, the inverter automatically tracks and analyses the photovoltaic generator's maximum power point
(MPP).
Disconnection from the grid
Indicates no grid voltage. This condition does not allow the inverter to connect to the grid
Indication of Warning (W message codes) or Error E warning codes)
Indicates that the inverter control system has detected a warning (W) or error (E).
Backup operating modes
Depending on the different modes that can be set, and after detecting the conditions required for the output to be enabled, the system
went into backup operation
Blackstart operating mode
• Ventilation anomaly
Indicates an anomaly in the operation of the internal ventilation system that could limit output power at high ambient temperatures.
• Failed association of internal inverter components (after replacement)
Indicates that the installed wiring box (only if replacing the inverter) was already associa-
ted with another inverter and that it cannot be associated with the new inverter.
• Overvoltage surge arresters triggered (where fitted)
Indicates that any class II overvoltage surge arresters installed on the AC or DC side have been triggered
• String protection fuses triggered (where fitted)
Indicates that one or more input string protection fuses that may be installed have been triggered
• Autotest (for Italian grid standards only)
The inverter is performing an Autotest
• Anomaly in the insulation system of the photovoltaic generator
Indicates that a leakage to ground from the PV generator has been detected, causing the inverter to disconnect from the grid.
• Indicates an operating anomaly in the battery unit
