d) Finally insert the DC connector into the posi�ve and nega�ve input of the inverter
,shown as
picture 5.6
AC connec�on can use 16-25mm, 105
℃
cable, please make sure the resistance of cable is
lower than 1.5ohm. If the cable is longer than 20m, it’s recommended to use 20-25mm cables.
Pic5.6 DC input connec�on
Warning:
Sunlight shines on the panel will generate voltage, high voltage in series may
cause danger to life. Therefore, before connec�ng the DC input line, the solar
panel needs to be blocked by the opaque material and the DC switch should
be 'OFF', otherwise, the high voltage of the inverter may lead to life-
threatening condi�ons.
Warning:
The AC cable line L1 is connected to socket 1; L2 is connected to socket 2; L3 is
connected to socket 3, the PE line is connected to the earth , and does not involve
N wire connec�ons, please do not insert N lines into the socket of N.
