CorrECt wIrIng sChEmE
To minimize the risk of an indirect lightning strike, avoid forming closed loops when designing the system. Check
that wiring is correct before starting the generator. If the measured open circuit voltage (V
oc
) and short-circuit
current (I
sc
) differ from the specifications, there may be a wiring fault.
soLar modULE PLUg ConnECtors
All solar modules are equipped with solar cables with 4-6mm² serving a temperature range from -40°C to 90°C.
The connectors have specified polarities; they are marked with ´+´ and ´-´ signs. Make sure that the connection is
safe and tight. Connectors should only be used to connect the circuit, but never used to turn the circuit on or off.
Connectors must not be exposed to direct rain or laid in water drains.
UsE of ProPEr ComPonEnts
Use cable extensions and plugs that are designed for outdoor applications. Ensure that they are in good electrical
and mechanical condition. Only cables with one conductor are to be used. Ensure that all materials meet the
requirements of the systems` maximum voltage, current, moisture, and temperature when they are exposed to
sunlight. Under normal conditions, a photovoltaic module is likely to produce more current and/or voltage than
that reported under Standard Test Conditions. Accordingly, the values of I
sc
and V
oc
marked on the module should
be multiplied by a factor of 1.25 when selecting electrical components voltage ratings, conductor capacities, fuse
type, and type of control components connected to the PV output.
The maximum series fuse rating is:
•
10A for modules with Hanwha Solar 125x125mm cells
•
15A for modules with Hanwha Solar 156x156mm cells
The maximum reverse current is known as series fuse rating multiplied by a factor of 1.35. Each module (or series
string of modules so connected) shall be provided with the maximum series fuse as specified.
For USA:
Refer to Section 690-8 of the U.S. National Electrical Code for an additional multiplying factor of 1.25 which may
be applicable.
ByPass dIodEs
When modules in series are partially shaded, it may cause reverse voltage across cells or modules, this may cause
undesirable heating to occur. The use of a diode to bypass the shaded area can minimize both heating and array
current reduction. All Hanwha Solar modules are equipped with factory installed bypass diodes. The factory
installed diodes provide proper circuit protection for the system.
othErs
During installation, be sure to tie the cable from the junction box to the mounting substructure with nylon line, etc.
to avoid direct contact of the cable with the back surface of the module.
