TROUBLESHOOTING PROCEDURES
HyPR User Interface Reports No Voltage from Array
Step 1
Verify that the Expedition is oriented for maximal sun exposure.
a. If Expedition is oriented for maximal sun exposure go to step 2.
b. If not, orient the Expedition for maximal sun exposure (
Expedition setup step 5
).
Step 2
Check Solar Leash connection at the HyPR.
a. If Solar Leash is properly connected to the HyPR go to step 3.
b. If loose or not connected, tighten or connect properly.
Step 3
Check the H4 PV connections between the Solar Leash and the Expedition (Figure 9).
a. If the H4 PV connections between the Solar Leash and the Expedition are secure, go to step
4.
b. If loose or not connected, tighten or connect properly (Figure 9).
Step 4
Check H4 PV series connections between each PV panel.
a. If the H4 PV connections between each PV panel are secure, go to step 5.
b. If loose or not connected, tighten or connect properly.
Step 5
. If the no-voltage problem persists, contact Solar Stik Technical Support.
This section contains troubleshooting information for locating and correcting operating troubles
that may develop in the Expedition. Each malfunction for a Expedition 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 Solar Stik Technical Support.
Equipment Condition Statement:
The HyPR 2000 is fully functional and operating normally.
HyPR User Interface Reports Low Voltage from Array
Step 1
. Verify that the Expedition is oriented for maximal sun exposure and is NOT shaded.
a. If the Expedition is oriented for maximal sun exposure and NOT shaded, go to step 2.
b. If not, remove the shading obstruction or move the Expedition to eliminate the shading,
c. Orient the Expedition for maximal sun exposure (
Expedition setup step 5
).
Step 2
Measure Expedition V
oc
at pins A and C of the bayonet connector of the Solar Leash.
a. If the Expedition V
oc
at pins A and C of the bayonet connector of the Solar Leash is within
acceptable limits (see
Measuring Maximum Power and Open Circuit Voltages
section), the
Expedition is operating normally. Contact Solar Stik Technical Support 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 H4 PV connections between the Solar Leash and the Expedition (Figure 9).
a. If H4 PV connections between the Solar Leash and the Expedition are connected properly, go
to step 4.
b. If loose or not connected, tighten or connect properly.
