3.2 Junction box

The junction box should be fixed on the top end of the module during assembly so as to

prevent the seepage of rain.

ET Solar provides a wiring type box. When the integrated J-box is adopted, no tool is

necessary for wiring. Just connect the modules in series according to "＋" or "-". You

can complete complex series and parallel connection easily and quickly using different

electric connectors provided by your supplier.

Connectors provided by different suppliers will not mutually match up. Different

connectors provided by one supplier will not match up either. Only one type of the same

connector from one supplier should be used to ensure the reliability of the electrical

connection.

There are other options in addition to using a wiring type junction box only consisting of

two terminals marked with "+" and "-" to represent the positive and negative terminals of

the power supply. Some junction boxes include three or more terminals. Only those

terminals indicated with "+" and "-" should be connected to the load. The others are

designed for the bypass diodes to reduce the damage to modules caused by hot spots and
