2-4. Electrical Installation 

 

Note: 

Maintenance  of  ESS  should  be  performed  by  qualified 
electrical technicians, and only after all AC and DC power are 
completely disconnected from ESS.   

 

  Confirm that the AC breaker between the inverter and utility grid is installed. 

Note: AC breaker is recommended as below.   
 
 
 
 
 
 
 
 

  Confirm that the breaker between the inverter and the photovoltaic array is installed. 

Note: The Ue: 600Vdc / Ie:20A specification breaker is recommended. 
 

  Confirm that the breaker between the inverter and back-up power load is installed. 

Note: AC breaker is recommended as below.   
 
 
 
 
 
 
 
 

  The AC and breakers must be disconnected when installing the inverter. 

  It  must  be  confirmed  that  the  power  of  the  AC  and  breakers  are  not  connected  during 

installation.
