Operating Instructions
Disabling PV Link
NOTE: Disabling a PV Link does NOT power down the
PV array if SnapRS devices are not installed. If SnapRS
devices are installed, array voltages are limited to less
than 80 VDC once PV Link is disabled or its DC discon-
nect is opened.
NOTE: Disabling PV Link does not power down REbus if
other devices are providing power to the DC bus.
NOTE: The disabled/enabled state of each PV Link per-
sists through AC power outages and DC bus power
cycling.
Proceed as follows 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 PV
Links in the system.
NOTE: Repeat the process to re-enable each PV Link.
AFD Self-Test
NOTE: Arc fault detection is always enabled.
Performing an arc fault detection (AFD) self-test confirms
arc fault detection functionality is working correctly. When
an arc fault is detected, the status message reads Arc
Fault.
Proceed as follows to conduct an AFD test:
1. On the PWRcell Inverter control panel, use the left
or right arrow keys to scroll to the page for the de-
sired PV Link.
2. Press the center button to access the device main
menu.
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 inverter control panel will dis-
play a result of Test Success or Test Failure. After a few
seconds, the AFD test will automatically clear.
PVRSS Self-Test

ration of the PVRSS system at any time by manually run-
ning the PV Link PVRSS self-test.
