Disabling Pv Link; Afd Self-Test; Pvrss Self-Test - Generac Power Systems PV Link Installation Manual

Disabling PV Link

NOTE: Disabling a PV Link does NOT de-
energize the PV array if SnapRS devices are
not installed. If SnapRS devices are installed,
in-array voltages are limited to less than 80
VDC.
NOTE: Disabling PV Link does not de-ener-
gize the DC bus if other devices are providing
power to the DC bus.
NOTE: The disabled/enabled state of each PV
Link persists through AC power outages and
DC bus power cycling.
To disable a PV Link:
1. On the PWRcell inverter control panel, use
the left or right arrows to scroll to the page
for the desired PV Link.
2. Press the center button to enter device
settings.
3. Use the up and down arrows to highlight
Disable and press the center button to
select.
4. Arrow right and press the center button to
Confirm.
5. Repeat steps 1–4 to disable any additional
optimizers in the system.
NOTE: Repeat the process to re-enable each
optimizer.

AFD Self-Test

NOTE: Arc fault detection is always enabled.
Performing an arc fault detection (AFD) self-
test confirms arc fault functionality is working
properly. When an arc fault is detected, the
status message reads Arc Fault.
To conduct an AFD test:
1. On the PWRcell inverter control panel, use
the left or right arrows to scroll to the page
for the desired PV Link.
2. Press the center button to enter device
settings.
3. Use the up and down arrows to highlight
Test AFD and press the center button to
enter the test state.
4. Arrow right and press the center button to
Confirm
Upon test completion, the control panel will
display a result of Test Success or Test Fail-
ure. After a few seconds, the AFD test will
automatically clear.

PVRSS Self-Test

After commissioning, you can verify proper
function and configuration of the PVRSS sys-
tem at any time by manually running the PV
Link PVRSS self-test.
To run the PVRSS self-test:
1. On the PWRcell inverter control panel
press the right arrow button repeatedly
until the first PV Link device page appears.
NOTE: The device page display should read
Disabled. If it does read not Disabled, press
the center button and Disable the PV Link.
2. Press the center button and select Test
PVRSS. to enter the Testing PVRSS state.
The display indicates Testing PVRSS during
the test process, which can take up to three
minutes. Upon successful completion, the dis-
play will read: Test Success. The PV Link (s)
will automatically re-enable.
