1.1 Normal working mode：FREQUNCY in the LCD display is setas 01. No matter whether there are AC loads connected to the inverter or not,the inverter’s outputterminal will always have voltage ready to supply power to the loads. Underthis mode, the LCD will be displayed as bellow:

1.2 Sleep mode：FREQUNCY in the LCD display is setas 02. If the power of the loads that connected to the inverter is lower than5% of the inverter’s rated power, there will be no output from the inverter. That is tosay, only the chip of inverter is working under such condition and the powerconsumption is only 1-6W; If the power of the loads that connected to theinverter is higher than 5% of the inverter’s rated power, then the inverterwill automatically start the inversion function and supply power to the loadswithin 5s. As shown below:

2. UPS function under utility mode(connected to battery and utility .Can beset as utility first, battery standby mode and battery first, utility standbymode).

2.1 Utility first, battery standby UPSmode: FREQUENCY in the LCD display is set as 01. When both utility and batteryare connected to the inverter, utility will supply power to the loads prior tothe battery. When utility is cut off, the battery will automatically continueto supply power after inversion.

Steps are as follows:

Step 1: When utility power is available, itwill output directly after voltagebeing stabilized and charge batteries at thesame time.

Step 2: When utility power is cut off suddenly,the inverter will convert DC power to AC power automatically to ensureuninterrupted power supply within 5ms.

Step 3: When utility power becomesavailable again, it will automatically transfer to utility supplying power toloads and charge batteries at the same time.

See Workflow as below.

LCD displayed as bellow:

2.2 Battery first, utility standby UPSmode: 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 as follows:

Step 1: When battery has enough power, itwill supply power to the loads directly

Step 2: When battery does not have enoughpower, it will automatically transfer to utility supplying power to the loads

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

See Workflow as below.
