Cable
TRIMAX Solar PV modules are equipped with two pre-terminated, temperature and UV resistant cable leads
(Rated 1500V DC, -40°C to 90 °C). The cross section of the cable is 4mm2 or 12AWG. Outer diameter is
5mm to 7mm. The smallest bending radius of the cables must not be less than 43mm. Cable damage caused
by excessive bending or by the cable management system is not covered by the warranty.
When selecting the size of the cables connecting the module strings to the solar inverter, observe the
electrical parameters specified on the module data sheet. To avoid overheating of the cables and the
connectors, the cross-section of the cables and the capacity of the connectors must be selected according
to the maximum system short-circuit current. The PV cable must be at least 4 mm2. Only use cables that are
certified for use with PV systems.
Observe the requirements of DIN VDE 0100-520. The standard applies to the selection and installation of
cable and line systems. Cable and line installations are the totality of one and/or more cables or lines or
busbars and their fastening means as well as their mechanical protection, if applicable. The standard contains,
among other things, requirements for types of cable and line installations, selection and installation according
to environmental influences, cross-sections of conductors, voltage drop in consumer installations, electrical
connections, selection and installation to limit fires, proximity to other technical installations, selection and
installation with regard to maintenance including cleaning.
