The difference between DC photovoltaic cable and AC photovoltaic cable

Photovoltaic Cable, named PV Cable,The solar photovoltaic cable consists of several cables. The 4mm2 PV cable -- the preferred choice for solar panels -- consists of multiple wires that work together to transfer solar energy from the panels to the batteries, inverters and connected devices and appliances. 4 mm2 solar PV cables have 2-5 wires set in the protective sleeve. There are many types of solar photovoltaic cable, the most popular are DC photovoltaic cable, DC photovoltaic cable main photovoltaic cable and AC connection photovoltaic cable.

DC Photovoltaic Cable cable,there are two types of DC photovoltaic cable: serial and modular. Both are compatible with solar panels and can be connected to the inverter with a 4mm2 DC PV cable by connecting the negative and positive leads. Although 4mm2 pv cables are popular, 6mm2 and 2.5mm2 PV cables can also be used. The size of the solar panel determines what photovoltaic cable should be used.

Insulation layers provide protection for cables, and they are color-coded for easy identification (blue is not charged, red is positively charged). Series pv cables can be connected directly to the inverter, or they can be connected to the inverter through ac connections, DC bushboxes, or node series technology. Some solar panels have built-in DC photovoltaic cables.

Main DC Photovoltaic  cables,these photovoltaic cables connect the negative and positive lines of the junction box to the inverter. 2mm2, 4mm2 and 6mm2 PV cables are single or double core. Dual-core PV cables are best suited for power boxes and/or inverters. Single core is ideal for a variety of solar panel installations.

AC connect PV cable, AC connect PV cable connects PV module to power grid and security mechanism. The 5 core AC connection is designed for small PV systems connected to three-phase inverters.
