Raudonas 4mm2 Helukabel saulės kabelis

Solar cable 4mm2 red

The most common type of cable is 4 mm2.Red insulation suggests the use of positive poles of the solar power plant, i.e. the plus of the inverter with the plus of the PV string.The use of colors makes it easier to connect the strings of panels to the inverter, ensuring that the correct polarity is maintained.

What to consider when choosing cables for photovoltaics?

The solar cable should meet the standards that are provided for cable operation in changing weather conditions (humidity, UV radiation).The cost of the cable in the entire photovoltaic installation is a minimum percentage, so it is worth choosing a solar cable of the best quality from a reputable, proven manufacturer.Its possible replacement could involve the dismantling of the panels, which would be costly and time-consuming.The cable is selected according to the cross-section, which takes into account both the current flowing in the chain of panels and the distance from the inverter, which is related to the resistance of the cable, which affects the voltage drops.

Parameters

The cable for solar applications can work in extremely low and high temperatures.Therefore, it can be used both on the roof and indoors, and it can be laid in the ground, in additional protective pipes.The use of a cable with these parameters ensures a long service life of the entire PV power plant.The manufacturer guarantees that the parameters of the solar cable will be maintained for a minimum of 25 years.
