User Interface Setup 

After making the physical connections and checking system voltages for the appropriate phase 

relationship, apply power to the entire system using the startup procedure below. 

Startup Process 

If batteries are not present, start units from grid. 

1. Shut battery breakers on each unit in the system, starting with the master unit.

A. Startup from battery will take approximately 45 – 60 seconds.

2. Verify grid settings are the same between the units.

Network Settings 

SkyBox stacking requires static IP addressing in firmware version 1.3.27.  In version 1.4 and greater, 

static IP addressing is still preferred, but dynamic addressing is also acceptable.  
Beginning with the master unit, log in as 

Installer

.  Under the 

Network

 tab edit menu, ensure the 

Ethernet Connection

 toggle is on 

Wall

 and set 

DHCP enable

 to 

No

.  

Repeat this step on the slave unit and change the 

Ethernet Connection

 to 

SkyBox
