NOTICE: 

1.

 

DON’T CONNECT THE PS TO 12V OR 24V BATTERY.

    The PS was 

designed for 48V system. Connection to the wrong battery will damage the PS. 

2.

 

THE AC SWITCH MUST BE TURNED OFF AT ANY TIME WHEN THE 

BATTERY IS CHANGED.

 

3.

 

Select  the  correct  battery  type  on  the  panel,  wrong  selection  will  damage  the 

battery  or  it  will  not  fully  charge  the  battery.  Do  not  change  the  battery  type 

selector when charging.   

4.

 

The model has a 6 amp AC input fuse inside of the unit. To replace the fuse you 

should remove the old fuse by opening the case and replace it with a new  6 amp 

fuse. 

5.

 

The  cables  for  battery  connection  or  device  to  the  PS  should  be  18AWG  min. 

Please keeping the connect points clean to avoid spark or electrical leakage. 

6.

 

Use the proper voltage solar panel or wind turbine for the connection, no voltage 

of over 72V.   

7.

 

When connecting a solar panel or wind turbine controller to the PS, please make 

sure of the correct polarity.
