Menu Structure
The operator interface consists of three levels:
•READ Menu - operation information provided to the user from the PV225S.
The READ Menu consists of all operational values, the date a nd time. These
can be viewed any time the PV225S has control powe r.
•WRITE Menu - operational parameters provided to the PV225S from the user.
The WRITE Menu consists of a goal state sub-menu, and all sy stem
configurable parameters. The WRITE Menu is pa ssword protected a nd may
only be changed by trained service technic ians. In particular are parameters
relating to utility protection setpoints .
•Data Logging - the collection of specific parameters values over a period of
time. The data logging feature is only av ailable if using the GUI. However,
the user does have the ability to view a sna pshot of specific data using the
“Read by ID” feature. See Table 2-3 on page 2–14 and Table 2-4 on
page 2–14.
Information reported back to the user (READ Menu) occ urs at the LCD above the
Universal Front Panel Control Unit (UFCU) and (if used) at the computer running
the GUI monitoring program. Making chang es to the parameters within the WRITE
Menu is done with the UFCU keypad or the GUI software program and requires a
password.
Upon system power-up, the operator interface LCD will display the system
operating state on the first line. The inverter ’s state of operation will be reported
on the second line. The PV Array’s state of operation will be reported on the third
line. The Goal target will be reported on the fourth line.
Important:
Specific grid-interface parameters within the WRITE Menu have been set in
the factory to the limits mandated by UL 1741. Any changes to these setpoints should be
agreed upon by the local utility and the equipment owner.
Important:
While in the WRITE Menu, the operator interface display will reset itself to
the standard display if there is no input for more than 2 minutes.
