1.1 Normal workingmode：FREQUNCY in the LCD display is set as 01.No matter whether there are AC loads connected to the inverter or not, theinverter’s output terminal will always have voltageready to supply power to the loads. Under this mode, the LCD will be displayedas bellow:

1.2 Sleep mode：FREQUNCY in the LCD display is set as 02. If the powerof the loads that connected to the inverter is lower than 5% of the inverter’s rated power, there will be no output from theinverter. That is to say, only the chip of inverter is working under suchcondition and the power consumption is only 1-6W; If the power of the loadsthat connected to the inverter is higher than 5% of the inverter’s rated power,then the inverter will automatically start the inversion function and supplypower to the loads within 5s. As shown below:

2.  UPSfunction under utility mode(connected to battery and utility .Can be set asutility first, battery standby mode and battery first, utility standby mode).

2.1 Utility first,battery standby UPS mode: FREQUENCY in the LCD display is set as 01. When bothutility and battery are connected to the inverter, utility will supply power tothe loads prior to the battery. When utility is cut off, the battery willautomatically continue to supply power after inversion.

Steps are asfollows:

Step 1: Whenutility power is available, it will output directly after voltagebeingstabilized and charge batteries at the same time.

Step 2: Whenutility power is cut off suddenly, the inverter will convert DC power to ACpower automatically to ensure uninterrupted power supply within 5ms.

Step 3: Whenutility power becomes available again, it will automatically transfer toutility supplying power to loads and charge batteries at the same time.

2.2 Battery first,utility standby UPS mode: FREQUENCY in the LCD display is set as 03.  When both utility and battery are connectedto the inverter, battery will supply power to the loads prior to utility. Whenbattery capacity is not enough, utility will continue to supply powerautomatically.

Steps are asfollows:

Step 1: Whenbattery has enough power, it will supply power to the loads directly

Step 2: Whenbattery does not have enough power, it will automatically transfer to utilitysupplying power to the loads

Step 3: After thebattery is fully charged (e.g. by solar or wind charge controller), it willthen automatically transfer to battery supplying power to the loads.

See Workflow asbelow.
