A: Photovoltaic solar cables can be mainly divided into two types: DC solar photovoltaic cables and AC photovoltaic cables. DC photovoltaic cables are generally used to connect solar panels and inverters, and the common specifications are 4mm2, 6mm2, 10mm2. AC photovoltaic cables are generally used to connect inverters and power grids. Conductor cross section is generally greater than 50mm2.
