Remedy:
2. Reconnect in correct configuration. Tighten all connections. Check wire
gauge and length of wire run. Refer to Suggested Minimum Wire Gauge
in Section 6.
3. Clean modules, clear obstruction or wait for conditions to clear.
4. If the open circuit voltage of a non-connected 12 volt module is lower
than the manufacturer’s specifications, the module may be faulty. Check
for blown diodes in the solar module junction box, which may be
shorting the power output of module.
