Frequently Asked Questions
What is a PV DC cable?
A PV DC cable is especially designed for use in sending direct current signals in solar systems. This cable is utilized to connect solar panels with combiner boxes, inverters as well as battery storage systems. Our PV DC connector has been developed to make ends of these cables ensuring secure low-resistance joints with protection rated IP67.
What is DC PV?
DC PV indicates the DC part of a solar system and the energy coming from the solar panels before the inverter converts it into AC. The DC section of solar systems can work with voltages of 1000V or even 1500V DC. Our PV DC Connector works at 1000V DC and has been tested at 6kV.
What is the difference between PV cable and normal cable?
PV cables Solar cables are made for use in solar installations, boasting both UV resistance, weatherproof insulation, and high temperatures (-40℃ to 90℃). To avoid corrosion, they use tinned copper conductors and are wrapped with thicker insulation to withstand rough weather. Ordinary cables (like any other standard PVC insulated cables) do not have this feature and get quickly damaged by exposure to UV rays, moisture, high or low temperatures. Our PV DC connectors are produced for connection with PV cables only.
What is a PV cable?
A photovoltaic cable is characterized as a single core cable utilized for joining solar panels and other units of a photovoltaic system. This type of cable contains UV resistant, weatherproof insulating materials and is capable of enduring high temperature conditions, moisture and mechanical stresses. The rating of photovoltaic cables lies in the range of 1000V-1500V DC and their cross-sections are 2.5mm², 4mm² and 6mm². Our connector is compatible with PV cables and provides a secure termination.
