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
