Menu Structure
The operator interface consists of three levels:
•
R
EAD
Menu
- operation information provided
to
the user
from
the PV225S.
The R
EAD
Menu consists of all operational values, the date and time. These
can be viewed any time the PV225S has control power.
•
W
RITE
Menu
- operational parameters provided
to
the PV225S
from
the user.
The W
RITE
Menu consists of a goal state sub-menu, and all system
configurable parameters. The W
RITE
Menu is password protected and may
only be changed by trained service technicians. 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 available if using the GUI. However,
the user does have the ability to view a snapshot 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 (R
EAD
Menu) occurs at the LCD above the
Universal Front Panel Control Unit (UFCU) and (if used) at the computer running
the GUI monitoring program. Making changes to the parameters within the W
RITE
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 W
RITE
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 W
RITE
Menu, the operator interface display will reset itself to
the standard display if there is no input for more than 2 minutes.
