at the H4 PV Expedition output leads (see
Measuring Maximum Power and
Open Circuit Voltages
section).
a. If the V
oc
is within acceptable limits, replace the Solar Leash.
b. If the V
oc
at the H4 PV Expedition output leads is equal to the V
oc
measured at pins A and C of
the bayonet connector, go to step 5.
Step 5
Check H4 PV series connections between each PV panel.
a. If the H4 PV connections between each PV panel are secure, go to step 6.
b. If loose or not connected, tighten or connect properly.
Step 6
Check V
oc
at the positive and negative terminals of the H4 PV connections of each PV panel.
a. If the V
oc
measured at the H4 PV connections of all panels is within acceptable limits* (see
Measuring Maximum Power and Open Circuit Voltages
section), contact Solar Stik Technical
Support for further assistance.
b. If the V
oc
measured at the H4 PV connections of any panel is not within acceptable limits*,
