Check your controller and battery first of all
，
make sure your battery is available 12V battery

Faulty connections
The wires should always be water tight and insulated. Poor wiring may cause loose connections,
corrosion and oxidation of the wires. Voltage levels at various parts of your connection can be
checked by a multimeter to help you find out the points at which low voltage problems start.
Do
not connect the solar power to the controller during the solar power voltage check

Solar panel faults
This condition is not common as most of the solar panels are able to sustain harsh weather
conditions and last for a long period of time. Checking on your solar panels is also advised as the
last resort. The main defects a solar panel may experience are: Delamination, junction box faults
( increased resistance in the junction boxes due to exposure to moisture)
.
Low power output from Solar panel / Battery charging slow.

Shading
Shading should always be avoided at all times. Shading causes massive loss of power output and
solar panels need high exposure to sun light so as to produce high power outputs. One should
always make sure that there are no tree branches blocking the solar panels from direct sunlight.
Dust and debris also causes shading. Solar panels should always be cleaned to prevent dust and
debris particles from causing shading on the solar panels.
Trouble Shooting
