PV Array–related Troubleshooting
No Power from the PV Array
Step 1
Verify the PV array is oriented for maximal sun exposure.
a. If the PV array is oriented for maximal sun exposure go to step 2.
b. If not, orient the PV array for maximal sun exposure.
Step 2
Check the Solar Cable connection at the Power Hub.
a. If the Solar Cable is properly connected to the Power Hub go to step 3.
b. If the Solar Cable is loose or not connected, tighten or connect properly.
Step 3
Check the connections between the Solar Cable and the PV array.
a. If connections between the Solar Cable and PV array are secure, go to step 4.
b. If connections are loose or disconnected, tighten or connect them properly.
Step 4
. If the no-voltage problem persists, contact the Field Service Representative.
This section contains troubleshooting information for locating and correcting operating troubles that
may develop in the PV array. Each malfunction is followed by a list of tests or inspections to help
you to determine probable causes and corrective actions to take. You should perform the tests/
inspections and corrective actions in the order listed. This manual cannot list all malfunctions that
may occur, nor all tests or inspections and corrective actions. If a malfunction is not listed or cannot
be corrected by listed corrective actions, contact the Field Service Representative.
Equipment Condition Assumption Statement:
The Power Hub is fully functional and operating
normally.
Lower Than Expected Voltage from the PV Array
Step 1
. Verify the PV array is oriented for maximal sun exposure and is NOT shaded.
a. If the PV array is oriented for maximal sun exposure and NOT shaded, go to step 2.
b. Remove the shading obstruction or move the PV array to eliminate the shading.
c. Orient the PV array for maximal sun exposure.
Step 2
at pins A and C of the bayonet connector of the Solar Cable.
a. If the PV array V
oc
at pins A and C of the bayonet connector of the Solar Cable is within
acceptable limits, the PV array is operating normally. See
the Field Service Representative for further assistance.
b. If V
oc
measured at pins A and C of the bayonet connector is below ~30 V*, go to step 3.
Step 3
Check the connections between the Solar Cable and the PV array output lead connectors.
a. If connections between the Solar Cable and PV array are connected properly, go to step 4.
b. If connections are loose or disconnected, tighten or connect them properly.
Step 4
Check the V
oc
at the PV array output lead connectors.
a. If the V
oc
is within acceptable limits, replace the Solar Cable.
b. If the V
oc
at the PV array output lead connectors is not within acceptable limits*, replace the
PV array.
*This value will vary depending on weather/environmental conditions (i e , lower if overcast)
