Six characteristics of photovoltaic module lightning protection combiner box

In accordance with the design requirements of photovoltaic system grid-connected power generation, according to the component parameters, temperature characteristics and the DC voltage range and maximum power tracking voltage range of the photovoltaic inverter input, a certain number of photovoltaic components are combined to form a DC lightning protection combiner box (outdoor type).

The connection mode of the photovoltaic module combiner box is 6-input and 1-output, that is, 6 primary combiner inputs of the same specification are combined and then output as 1 DC. The photovoltaic module combiner box has the following features:

1) Protection grade IP65, meeting the requirements for outdoor installation.

2) 6 battery strings can be connected at the same time, and the maximum allowable current of each battery string is 13A;

3) The junction box provides protection for the strings in the centralized photovoltaic system;

4) Using Bussmann-PV photovoltaic fuse protection can ensure a quick response to errors and alarms;

5) Up to 10 wires are installed in parallel in the same junction box, with fuse protection devices installed on both the positive and negative poles.

6) It can be connected to the cables of photovoltaic panels in a variety of ways
