Similar to the traditional inverter connecting, the input of PV panel energy can
be realized by using MC4 PV terminal, the detail steps are as follows：
，
Max PV voltage：550V (consider the lowest temperature)
≥
1.Turn off PV switch.
2.Insert PV panel positive and negative cables into MC4 terminal then connect
positive pole(+) of connection cable to positive pole(+) of PV input connector,
connect negative pole(-) of connection cable to negative pole(-)of PV input
connector, please pay attention to PV input voltage and current within
permission Limit:
Max PV input current: 12A
Max PV input power per string: 4000W.
Remark: 1.We suggest you use the cable 4mm2/12 AWG to connect.
2.Please do not connect to DC source!
5.5.2 Connection of AC terminal and off grid terminal
SPH has a grid output terminal and off grid out terminal,look down on the SPH from
the front,the terminal on the left (on grid) is grid outlet for connecting grid,the
terminal on the right is an emergency power outlet for connecting critical load.

Step 2: Thread cables through pressure screw, seal ring, threaded sleeve in
sequence, insert cables into connection terminal according to polarities indicates
on it and tighten the screws.
