EZA2500W series 

Quick Manual / Practical (II) 

 

5) Automatic Grid CV with battery CC mode operation 

In this mode, EZA limits the current with CIB (

Current

 Limit of Battery) value set on the battery 

side when discharging in Automatic grid CV mode. 

 

 

①

 Turn on the radio buttons for “Autonomy” and “With batt CC” in 

②

 of the previous 

operation. 

②

Perform the operations after 

③

 above. 

 

 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

In Automatic grid CV mode, EZA judges and switches between 
charging and discharging so that the grid voltage is constant. 
 
However, when the battery is fully charged or emptied, it is 
impossible to operate at the constant voltage. So it is necessary to 
pay attention to the remaining battery capacity.  
 
I must also think about what to do when the battery is fully charged 
or empty.
