 XGI 1500-DCG

 

Installation and Operation Guide 

Models: 

XGI 1500-250/250-600-DCG 

 

XGI 1500-225-600-DCG 
XGI  1500-200/200-480-DCG 
XGI 1500-175-480-DCG 

 

   

 

 

 

 

 

 

Note:  These XGI 1500 inverter models require a DC negative ground 

and will prevent Potential Induced Degradation (PID) in PV modules 

that are susceptible to this effect.
