Main Standard Integrated Functions
This section contains a brief description of the equipment functions, to allow users who are not familiar with
the operation of PV fields to better understand this manual.
Device for constant isolation control:
This is a device which constantly checks the isolation between the
earth and the polarities of the PV field and the earth. This function is obtained by measuring the isolation
resistance: the equipment is factory-set to detect isolation loss when the isolation resistance between polarity
+ or polarity – and the earth drops below 850 k
Ω.
MPPT (Maximum Power Point Tracking):
A sophisticated computing performed by the microprocessor
allows the inverter to detect the optimum operating point of the PV field, corresponding to the max power that
can be produced by the field depending on current solar radiation conditions.
Automatic Disconnecting Means:
This device automatically disconnects the self-generation plant from the
grid when parallel operation is no longer possible. This typically occurs when the grid “opens” due to
maintenance needs or to safety circuit tripping. This function allows the inverter to instantly disconnect from
the grid, thus avoiding unwanted stand-alone operation of the plant and electric shock hazards for the
operators working on the grid. Trip times and levels are factory-set according to the applicable safety
standards. To modify the factory settings, please refer to the sections relating to the inverter programming.
The ratings of this safety function have been certified as prescribed by the Grid Administrator.
When required by the Grid Administrator, a simple self-test procedure performed via the touchscreen display
allows checking the efficiency of the grid disconnecting device.
