The thicker wire loses less energy on long runs or with high current modules. 6 mm², black for the minus pole, 1.5 kV DC, -40...90 °C, TUV certified.
It is the cable that carries the current from the panels to the inverter, in the version with a thicker conductor. A thicker wire opposes less resistance, just as a wider pipe carries water more easily, so less energy is lost along the way. The black variant marks, by convention, the minus (negative) pole of the panel string.
The 6 mm² cross-section is chosen when the distance from the panels to the inverter is large or when the modules have a high current, so that voltage is not lost along the route. It withstands 90 °C in continuous operation and goes down to -40 °C, so it covers both the roof heated in summer and harsh winters. The insulation does not degrade in the sun, withstands standing water and even submersion, and in a fire it does not propagate the flame and does not release halogenated gases. Being thicker than the 4 mm² variant, it requires MC4 connectors with a gland suited to the larger outer diameter, otherwise the sealing is not achieved correctly and the protection warranty of the joint is no longer valid.

Specifications confirmed from the manufacturer's datasheet
Single-core photovoltaic cable of 6 mm2 from the TOPSOLAR PV H1Z2Z2-K range, in the black variant for the negative pole. The conductor of tinned electrolytic copper, class 5 (flexible) according to EN 60228, offers a lower ohmic resistance than the 4 mm2 variant, which reduces the voltage drop and the losses on long runs or with strings of high current modules.
The insulation and the sheath are of halogen-free cross-linked rubber. The cable is TUV Rheinland certified according to EN 50618 and AENOR according to IEC 62930, with a rated voltage of 1.5/1.5 (1.8) kV DC and 1/1 kV AC. The maximum conductor temperature is 90 °C in continuous operation and 120 °C for 20,000 cumulated hours, with resistance to 250 °C for a maximum of 5 seconds under short circuit and a minimum service temperature of -40 °C.
The resistance to UV and ozone complies with EN 50618 and IEC 62930, and the water resistance covers AD7+ immersion and AD8 submersion. The reaction to fire class according to CPR is Cca-s1b, d2, a1, with flame non-propagation according to EN 60332-1-2 and without emission of halogenated gases. The minimum bending radius is 4 times the outer diameter for cables of up to 8 mm and 5 times the diameter for those between 8 and 12 mm.
The 6 mm2 cross-section is chosen in projects with high current modules, with long strings or in photovoltaic parks where the distance to the string box requires limiting the voltage drop below the design threshold. It is terminated with MC4 connectors in gland variants compatible with the larger outer diameter of the 6 mm2 cable.
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.
