• Tyco grounding hardware comes in a package that includes the grounding bolt, mounting and grounding hex
• Electrical contact is made by penetrating the anodized coating of the aluminum frame, and tightening the
mounting hex nut (come with the star washer) to the proper torque of 25lbf.in.
• Grounding wire size (6 to 12 AWG solid bare copper) should be selected and installed underneath the wire
binding bolt.
• The wire binding bolt should be tightened to the proper torque of 45lbf.in.
• The Tyco grounding bolt is only listed for use with 6 to 12 AWG bare solid copper wire.
7.3 Module wiring
All wiring should be performed, by qualified installers, in accordance with the local codes and regulations.
Modules can be connected in series to increase the operating voltage by plugging the positive plug of one module
into the negative socket of the next. Before connecting modules always ensure that the contacts are corrosion free, clean
and dry.
The product can be irreparably damaged if an array string is connected in reverse polarity to another. Always verify
the voltage and polarity of each individual string before making a parallel connection. If you measure a reversed polarity
or a difference of more than 10V between strings then check the string configuration before making the connection.
Maysun Solar modules are provided with stranded copper cables with a cross sectional area of 4mm²(0.006in²)
which are rated for 1000V DC, 90°C and are UV resistant.( For MS.**, 1500 V DC, 90°C and are UV resistant) All
other cables used to connect the DC system should have a similar (or better) specification. Maysun Solar recommend that
all cables are run inappropriate conduits and sited away from areas prone to water collection.
The maximum voltage of the system must be less than the maximum certified voltage 1000V typically (For TSM-
PE05A.**, PE14A.** , less than 1500V) and the maximum input voltage of the inverter and of the other electrical
devices installed in the system. To ensure that this is the case, the open circuit voltage of the array string needs to be
calculated at the lowest expected ambient temperature for the location. This can be done using the following formula.
System voltage=N*Voc*[ 1
＋
λvoc (Tmin -25℃)]
N——number of modules in series
Voc— —open circuit voltage at STC (refer to product label or datasheet)
λvoc——Thermal coefficient of Voc of each module (refer to product datasheet)
Tmin— — minimum
Each module have two standards 90°C sunlight resistant output cables each terminated with plug &
play connectors. The wire type and gauge of the output cables are 1000V (For MS.**, ** which are 1500V
DC) rated PV Wire cable and are 12AWG in size. This cable is suitable for applications where wiring is
exposed to the direct sunlight. We require that all wiring and electrical connections comply with the
appropriate National Electrical Code.
The minimum and maximum outer diameters of the cable are 5 to 7mm(0.038 to 0.076in2).
For field connections, use at least 4mm2 copper wires insulated for a minimum of 90°C and sunlight
resistance with insulation designated as PV Wire.
The minimum bending radius cables should be 43mm( 1.69in).
