PERATION LOGIC
The inverter has been designed for automatic operation which does not normally require any operator intervention.
Possible inverter status conditions include:
„Standby‟: the inverter cannot feed due to a lock. The problem must be solved and an unlock command given. Lock
codes begin with „L‟.
„Alarms present‟: a problem is preventing the inverter from starting feeding. If the cause of the problem is fixed, the
inverter will restart automatically. In particular, the inverter is in this condition if the „W09 Low Vdc‟ or „A07 High Vdc‟
alarms are present.
„Wait‟: the inverter is running the countdown before starting the feeding sequence. This wait, usually very short,
becomes important after low radiation events, low string voltage or very low power output (typically at sunset or on
particularly cloudy days).
„Irradiation test‟: the inverter is verifying that the PV generator is able to produce enough power to allow normal feeding.
„GFCI Test‟: the inverter is trying the differential current sensor with a similar function on the differential switch test
button (cut-out).
„Isolation Test‟: the inverter is verifying PV generator isolation with respect to grounding. In the event of low isolation, the
inverter will remain in this mode until the problem has been resolved, showing a second warning line „F07 Insulat. KO‟ to
then restart automatically.
„Precharge‟: the inverter is preparing the bulk capacitor for feeding.
„Check AC‟: the inverter checks the correctness of the grid parameters before (re)connecting for a time that depends on
the nation set during installation (see “connection” line in Table 2).
„Feeding the grid‟: the inverter is emitting power to the grid.
Start ramp: Some standards require that the inverter begins to feeding the grid following a trend ramp-shaped.
The sequence for the feeding is as follows:
„Standby‟, ‟ Alarms present‟, „Wait‟, „Irradiation test‟ (if applicable), „GFCI Test‟,
„Isolation Test‟, „Precharge‟, „Check AC‟, „Feeding the grid‟.
On entering „Feeding the grid‟ the presence or absence of the power limitation ramp depends on the nation set during installation.
