PV+ positive input pole PV1- negative input pole
BAT wiring method:
①
Before wiring, disconnect external breaker at first, and then confirm whether the used cable is thick enough.
Please refer to chapter “ 2.2 Wiring Specification and Breaker Type ” . BAT wire shall be connected with
the machine via O-shaped terminal. It is recommended to use the O-shaped terminal with 5mm inside
diameter. The O-shaped terminal must compress BAT wire firmly to prevent excessive heating caused by
great contact resistance;
②
Correctly connect BAT wire in accordance with cable sequence and terminal position shown in the figure
below.

Warning notice:
①
Input from mains supply, AC output and photovoltaic array may generate high voltage. Before wiring, make
sure to break the breaker or fuse;
②
During wiring process, make sure to pay attention to the safety; during the wiring process, please don’t
close the breaker or fuse. At the same time, guarantee that “+” and “-” poles of different parts are
correctly connected with wires; a breaker must be installed at the battery end and selected based on chapter
“2.2 Wiring Specification and Breaker Type”. Before wiring, make sure to break the breaker to prevent
strong electric spark generated during wiring. At the same time, avoid battery short circuit during the wiring
process; if the all-in-one machine is in the area with frequent thunder, it is suggested to install an external
arrester at PV input terminal.
