JUNCTION BOX AND TERMINALS
• The junction boxes of the modules are in the back of
the modules.
• Each module is equipped with one junction box
containing terminals for both positive and negative
polarity, and bypass diodes.
• The polarity should be respected in the connections
to ensure the correct operation of the modules with
the polarity symbols engraved onto the body of the
junction box.
DIODES
• The shading of a cell can cause it to have reserve
voltage. This cell will therefore consume the power
generated by the others cells in the series, producing
an undesired heating of the shaded cell.
• A hot spot effect is existent when a solar cell within a
module generates less current than the string current
of the module or of the PV generator. This occurs
when the cell is totally or partially shaded, damaged, or
when cells are electrically mismatched. The shaded cell
becomes reverse biased and dissipates power in the
form of heat.
• The use of protection, or bypass diodes reduces the
risk of heating of the shaded cells, limiting the current
that can circulate through them and thereby avoiding
breaks.
• All modules are equipped with factory installed bypass
diodes. These diodes provide proper circuit protection
for the systems within the specified system voltage,
so that you do not need any other additional bypass
diodes.
• Contact your Samsung Authorized Representative or
system house for proper diode type, if it is necessary
to add or change diodes due to system specifications.
maintenance
If you need electrical or mechanical inspection or maintenance, it is recommended to have a licensed
authorized professional carry out the inspection or maintenance to avoid the hazards of electric shock
or injury.
MAINTENANCE COVERS THE
FOLLOWING PROCESSES:
• Periodic cleaning of the module.
• Visual inspection of possible internal deterioration of
the water-tightness of the module.
• Control of the state of the electrical connections and
wiring.
• Eventually, control of the electrical characteristics of
the module.
PERIODIC CLEANING OF THE
MODULE
• Dirt on the module surfaces causes cell shading and
can lead to reduced power output.
• It is recommended to clean the surface of the module
with water and a soft cloth or sponge, when required.
• Under no circumstances should dirt be scraped or
rubbed off the modules when dry, as this can cause
micro-scratches on the surface of the modules and
reduce the transparency of the module glass. Instead,
a mild non-abrasive detergent may be applied for
persistent dirt.
VISUAL INSPECTION OF THE
MODULE
• Possible breaks in the glass.
• All fasteners are secure, tight and free of corrosion.
• All electrical connections are secure, tight, clean, and
free of corrosion.
• The mechanical integrity of the cables is intact.
• All bonding points to Earth Ground are tight, secure,
and free of corrosion to ensure continuity between the
modules and ground.
CONNECTION AND WIRING
CONTROL
• Electrical and mechanical connections should be
preventively inspected every 6 month.
• Check the fastening and state of the module’s
terminals of the connection cables.
• Check the water-tightness of the terminal box.
