Figure 2-4 Grid or Generator Power Supply Wiring Diagram 2
1. Wirings as Figure 2-3 system wiring drawings according to inverters power, check and confirm
the connections to be correct.
2. Disconnect the switch Q1, and then close Q2, switch to grid or diesel engine power;
disconnect Q2, and then close Q1, switch to PV power supply; Figure 2-4 show inter-locking
connection between connector KM1 and KM2, KM1 close is PV power supply, KM2 close is
grid or generator power supply.
3. When grid or generator power supply, setting H00.01=0, power supplied by grid.
4. For water pump’s frequency, please refer to F01 group code, H00.02~H00.12 function code
does not work.
5. When change to PV power supply, setting F04.1=38 and close the terminal DI2 (or setting
H00.01=1).
Note:
When the bus input terminal does not install the diode protection, PV panel switch Q1 will be
prohibited to close together with grid power input switch Q2, or the panel will be damaged.
