24 strings 24 in 1 out 1500v 600a pv solar combiner box junction boxes

24 strings pv solar combiner box 24 in 1 out  Adopting hot-dip galvanized steel plate, the cabinet structure is safe and reliable, with sufficient mechanical strength to ensure that there is no shaking or deformation during component installation and operation; The protection level is IP65, which is waterproof, ash proof, rust proof, and salt spray proof, meeting the requirements for outdoor installation. It can be connected to 24 photovoltaic arrays simultaneously.

Advantages of photovoltaic combiner box:
1. The photovoltaic combiner box improves the safety of solar panels and the entire photovoltaic power plant.
2. Photovoltaic combiner box, also known as DC distribution board, as a plug and play solution, is factory assembled with monitoring equipment, fuses, surge protection devices, and isolation switches.
3. Different shell sizes can flexibly cover a range of up to 32 strings.
