The configured number of batteries must match the actual number. When the actual number 
changes, change the configured number. If the configured number is less than the actual 
number, the battery lifespan is shortened. If the configured number is greater than the actual 
number, battery leakage may cause a fire. 
 
 
 
If the system uses three-phase input three-phase output, set Output mode to Three-phase. 
If the system uses three-phase input single-phase output or single-phase input single-phase 
output, set Output mode to Single-phase. 
 
Set Voltage level and Frequency level based on the rated voltage and frequency. In the 
case of single-phase output, set Voltage level to 220 V (default), 230 V, or 240 V; in the 
case of three-phase output, set Voltage level to 380 V (default), 400 V, or 415 V.
