New PW - Used to change the password for accessing the SETTINGS menu. The default
password is 0000 and can be changed using the display keyboard.
• Use ENTER to scroll the digits (from left to right)
• Use ESC to return to the previous digit (from right to left)
• Press ESC several times to return to the previous menus
• Use DOWN to progressively scroll the numerical scale downwards (from 9 to 0)
Be careful to memorize the new password. For security purposes there is no reset
function. If the password is misplaced it will not be possible to access the inverter.
Cash - Used to set the name of the currency and the value given to 1 kWh of energy produced.
The correct setting of these parameters displays the actual earning/saving given by the system.
• Name: the chosen value is set (default is $, USD).
• Val/KWh: indicates the cost/incentive of 1 KWh expressed in the chosen currency (default
is 0.16).
Time – Used to set the current date and time (daylight saving time not included).
Language – Used to set the menu language.
Vstart – Used to set the Vstart voltage (separately for both channels if they are congured in
independent mode). Change the activation voltage only if necessary. A conguration program
that can help to correctly size the photovoltaic system is available on at http://www.stringsizer.

Alarm - This section of the menu allows programming of the alarm relay function (available
as a normally open contact – N/O, and also as a normally closed contact – N/C). This contact
can be used, for example, to activate a siren or a visual alarm, control the disconnect device of
an external transformer, or control an external device. Maximum ratings of the alarm contact:
240Vac/1A and 30Vdc/0.8A.
The switching of the relay can be set in four different modes:
• PRODUCTION: the relay switches when the inverter connects to the grid.
• ALARM: the relay switches when there is an alarm (code E).
• ALARM (congurable): the relay switches if there are alarms (code E) or warnings (code W)
chosen by the user from a list (the list may also show choices that are not available for the
specic model).
• CREPUSCULAR: the relay switches only when the input voltage exceeds the input voltage
set for connection to the grid.
The operating modes are described in further detail below:
Production: the relay switches when a connection to (or disconnection from) the grid occurs.
When N/O (or N/C) contact is chosen, it will stay open (or closed) until the inverter is connected to
the grid. Once the inverter starts to export power, the relay changes state and closes (or opens).
When the inverter disconnects from the grid, the relay contact returns to its position of rest, open
(or closed).
