Grid Interface Protection Menu
Grid-interactive requirements vary in different locations around the world. The grid-interactive
settings are adjustable in the
Grid Interface Protection
and
Grid Support
menus. These
menus are only available with installer-level access. These settings are generally controlled by
the local authorities or interconnection agreement and should not be altered by the end user.
The installer password must be changed from the default to access these settings. Once it has
been changed, the settings can only be accessed with the installer password.
This menu includes the following:
x
Operating Frequency
. It can be selected to either 50 or 60 Hz. This setting changes the inverter’s
output frequency, but it also changes the input (and grid-interactive) acceptance parameters. See
page 22 for more information on the inverter’s frequency.
x
Clearance Time
during power loss.
x
Maximum Sell Current
when exporting power to the utility.
x
The
Grid Support
menu contains multiple voltage, frequency and time parameters for operation.
The grid-interactive function can only operate while the grid is stable and within specific limits.
a
In
Grid Tied
mode, the inverter operates in accordance with the
Grid Support
settings. If the
AC voltage or frequency vary outside these limits, the inverter will disconnect to isolate itself and
its protected loads.
Grid Support
settings adhere to specific standards, such as California's Rule
21 or HECO Rule 14H. These limits override the AC source acceptance limits on page 25, which
are used in most other modes. See page 37 for more information on the
Grid Support
function.
a
Before operating in
Grid Tied
mode, be sure to obtain any necessary interconnection
agreements or related documents from the utility company or local building authority. These
documents will typically specify the grid support and interface protection settings that must be
used for that installation.
a
The
Grid Support
menu has a
Regulatory Specification
screen that displays the standard
currently loaded on the system and the settings loaded into the
Grid Support
options from a .GIP
file. (See below.) The default standard (and settings) is
IEEE 1547
.
a
The items in the following list are the selectable
Grid Support
options. The utility company may
need to review these items to make certain their standards are met.
Low
and
High Voltage
and
Frequency Ride-Through
Fixed Power Factor
Ramping
Frequency Watt
Volt Watt
Volt/VAr
If the grid is outside the parameters of the applicable standard, the inverter disconnects from the
AC source. It will not reconnect until the source meets the voltage and frequency

for the duration of the timer in that menu.

If the inverter stops selling or disconnects due to
Grid Interface Protection
, the system display
will show the reason.
Sell Status
messages are listed on page 55.
Disconnect
messages are
listed on page 54. Often these messages will be the same.

Upload Grid Protection
. This screen automatically loads a “package” of grid support settings from
a .GIP file. See the
Radian Series Inverter/Charger Installation Manual
for instructions.

system display menus, including those on this page.
