The conductor that earths the structure, the panel frames and the equipment enclosures. 6 mm², flexible copper, halogen-free insulation (LSZH), 450/750 V, flame retardant.
This is the safety wire of the installation: the one that earths all the metal parts on which there should never be any voltage, that is the structure on the roof, the panel frames and the equipment enclosures. If a fault accidentally reaches the metal, the current has a way to leave into the ground, instead of passing through whoever touches that metal. The conductor is flexible, made of numerous thin wires, so it bends easily and is routed comfortably along runs with tight bends, inside the distribution boards.
The 6 mm² cross section is the value usually required for the protective conductor of a photovoltaic structure, so it covers the connections from the mounting structure, from the panel frames and from the inverter enclosures up to the main earthing bar. The insulation is of the halogen-free type (LSZH), which matters in a fire: the material does not sustain the flame, produces much less dense smoke and does not release the corrosive gases that classic PVC insulation releases, a real advantage on runs that pass through technical spaces or through rooms with people. The nominal voltage is 450/750 V, and the conductor withstands 70 °C in continuous operation. It is installed with crimped lugs or with dedicated earthing clamps. By convention, the protective conductor is marked green-yellow, so that it is immediately recognised by any electrician who intervenes later.
Single-core flexible conductor of 6 mm², electrolytic copper class 5 according to EN 60228, insulation of halogen-free thermoplastic compound type Z1 (LSZH), nominal voltage 450/750 V, maximum conductor temperature 70 °C in continuous operation. Fire behaviour: flame non-propagation according to EN 60332-1-2, smoke with reduced opacity according to EN 61034, no halogenated corrosive gases according to EN 60754 / EN 50267. Intended for protective conductors and equipotential bonding connections: metal mounting structure, module frames, inverter enclosures, DC and AC distribution boxes, towards the main earthing bar. Terminations with crimped lugs or dedicated earthing clamps, with green-yellow marking or insulation according to the marking rules of electrical installations.
Suitable for any photovoltaic installation that needs earthing and equipotential bonding connections, especially where the run passes through technical or inhabited spaces.

Generic product — standard specifications
Single-core flexible conductor of 6 mm2 intended for the earthing and equipotential bonding connections of photovoltaic installations. The core is of electrolytic copper, class 5 (flexible) according to EN 60228, made of numerous thin wires, which allows routing along runs with tight bends, inside the boards and along the mounting structures.
The insulation is of halogen-free thermoplastic compound type Z1 (LSZH), with a nominal voltage of 450/750 V and a maximum conductor temperature of 70 °C in continuous operation. In case of fire the material does not propagate the flame according to EN 60332-1-2, releases smoke with reduced opacity according to EN 61034 and does not emit halogenated corrosive gases according to EN 60754 / EN 50267, unlike classic PVC insulations. This characteristic is relevant on runs that cross technical spaces, shared cable trays or rooms with people present.
In photovoltaic installations the 6 mm2 conductor is used for earthing the metal mounting structure, the panel frames, the inverter enclosures and the DC and AC distribution boxes, as well as for the equipotential bonding connections towards the main earthing bar. The 6 mm2 cross section is the value usually required for the protective conductors of the photovoltaic structure.
It is installed with crimped lugs or with dedicated earthing clamps; for identification, the protective conductor must be marked or insulated in the green-yellow combination, according to the marking rules of electrical installations.
Without this cable the battery and the inverter do not talk to each other. It transmits the state of charge and the battery limits; RJ45-RJ45, 3.5 m on the Pytes V5 B2I version.
Carries the current from the Pytes battery to the inverter on the negative pole (black). Flexible stranded copper, with ring terminals already crimped for the battery terminals.
Carries the current between the Pytes battery and the inverter on the positive pole (red). Flexible stranded copper, with crimped ring lugs for the screw terminals.
A cable that can be buried directly in the ground, with a metal screen protecting against blows. Two copper conductors of 4 mm², 0.6/1 kV, PVC sheath, fire class Dca.
