Sunlight shining on the panels will generate voltage, high voltage in
series may cause danger to life. Therefore, before connecting the DC
input line, the solar panel needs to be blocked by the opaque material
and ensure that the DC switch is 'OFF', otherwise, the high voltage of
the inverter may lead to life-threatening conditions.
After the DC terminal is connected, do not close the DC switch first. Connect the
AC terminal to the AC terminal of the inverter, the AC terminal is equipped with
three-phase AC terminals that can be conveniently connected. F lexible cords are
recommended for easy installation. The specifications are as shown in table 5.2

Pic 5.7 AC connector structure
The AC output connector is divided into three parts: matching socket, sleeve
and sealing sleeve, as shown in Picture 5.7, the steps are as follows:
Step 1 Remove the cable sealing ring and sleeve in sequence from the ac
connector.
Step 2 Separate the sleeve from the matching socket, as shown in figure 5.7,
the connector body has two locking holes, and press the locking valve in the hole
inward to separate the matching socket from the sleeve.
Step 3 use strippers to strip the protective sheath and insulation layer of the
ac cable to the right length, as shown in Picture 5.8
Prohibit use a single circuit breaker for multiple inverters ,
prohibit the connection of load between inverter circuit
breakers.
