OPERATION 

After connecting batteries, AC input cables, and loads, the inverter is now ready to 
work. 

3.1 Standby Charging Mode 

The battery can be charged without switching on the inverter, and such operation is 
called Standby Charging Mode. When AC input cable and battery is connected, the 
inverter will enter into Standby Charging Mode and LCD will be turned on with the 
following display. 

  

 

If  PV  string  is  also  connected  with  enough  voltage,  the  display  will  be  as  shown 
below to indicate the power flow from PV string. 

 

 

Even if AC input is absent, PV power can still charge the battery and the display will 
be as shown below.
