btaining the service level password
An advanced password can be provided to authorized installers to allow access to the service menu upon
completion of required documentation. Contact customer service at 877-261-1374 to request this password.
The password obtained is valid for a period of 15 days.
NOTE! Because the service level password is date sensitive, it is necessary to have the correct date
and time set on the inverter display to successfully use the password. Refer to the Settings menu in
section 4 for instructions to set the date and time.
The password to access the Service menu is to be used by trained ser-
vice personnel only. It is based on data associated with a specific serial
number and different for every inverter
Locate the following information, which is necessary to generate the
password, from the product label of the inverter as shown at left.
• Serial number - SN
• Week of manufacture -WK
The same data can also be found on the INFO menu on the inverter display.

isplay messages and error codes
The equipment indicates errors/warnings on the display only if the input voltage is higher than the Vdcmin
voltage (POWER LED flashing or on; see Operations, part 4). Next to each state of the inverter, (indicated
through the steady or intermittent lighting of the relevant LED), a message that identifies the operation it is
carrying out or the detected fault/anomaly, is also indicated in the two-line display. Messages identify the
current status of the inverter and do not relate to a fault.
When a (W) with a number after it appears in the display, it indicates a Warning Code and is usually cleared
through an orderly shutdown/re-set or a self-corrective action performed by the inverter. Alarms or (E) codes
identify a possible equipment failure, fault, or incorrect inverter setting or configuration. Some of the (E) codes
may require technical support to assist in correcting a fault. Any and all attempts to correct or clear a fault
must be performed by qualified personnel. Typically, the (E) code can be cleared once the cause or fault is
removed. Some of the (E) codes may indicate a fatal error and require technical support for diagnostics and/
or a product replacement.
When the red LED comes ON, try to reset the warning using the multi-function ESC button on the panel. If the
inverter reconnects to the grid, the fault was due to temporary phenomena.
WARNING! In the event of malfunction, it is extremely dangerous to try to eliminate the fault. Follow
the instructions given below or contact a specialized technician if you do not have the experience
and necessary qualifications to work safely.
