make sure that the maximum input voltage of the inverter is not exceeded.
Connection of PV terminal
Chart 5.9
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:
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 voltage: 550V (consider the lowest temperature)
Max PV input current: 12A
Max PV input power per string: 4000W
Remark:
1. We suggest you use the cable≥4mm
2
/12 AWG to connect.
2. Please do not connect to DC source!
5.4.2 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.
