Preface 

The SkyBox True Hybrid Energy System is a machine that connects the solar panels on your roof to the 
toaster in your kitchen so you can use solar or battery energy to power that toaster.  This guide will walk you 
through the basic decisions you need to make to successfully set up a SkyBox.  We will also dive into the 
details for each component of the SkyBox for ambitious installers and tinkerers out there. 

This Handbook does not have linear instructions.  You can pick which chapter is most relevant to your situation 
and go straight there without wading through pages of unnecessary information.  However, this Handbook  
IS NOT a replacement for the 

SkyBox Quick Start Guide

 provided in the box with the product.   

We won’t be reviewing any wiring steps, just operation and behaviors.   

If you’re a SkyBox newbie, the best place to start is at the beginning with 

Making it Run

 on page 5.  Go 

through this section, try it out on your SkyBox, then come back and read about all the details and special 
features that make SkyBox unique.  The details and special features of this inverter are covered in 

The Nitty 

Gritty

 on page 17. 

The following sections will sometimes make references to SkyBox settings.  These are shown in 

bold italic

 

text.  Detailed explanations can be found in the 

SkyBox Programming Guide

The Screen  

The SkyBox display is a resistive, touch-sensitive interface. 
Unlike your cell phone, this screen supports single touch and 
relies on pressure from your finger or a stylus — it does not 
make use of the human body's natural conductivity.  It 
monitors all aspects of SkyBox performance.  Items such as 

b u t t o n s

t i l e s

 

, or icons respond or open when tapped 

with a finger or stylus. 

For  a  description  of  all  controls,  see  the 

SkyBox  Overview 

Guide

  (

).    For  an  in-depth  description  of  all  functions, 

see the 

SkyBox Programming Guide

 (

). 

The Set-Up Wizard 

The set-up wizard walks you through each section of settings in order to get your SkyBox up and running.   
The first time your SkyBox is turned on, the Wizard will appear.  The Wizard does not cover rapid shutdown  
or the use of the auxiliary terminals. 

One setting in the Wizard is the selection of AC Profile.  The AC Profile tells the SkyBox how to interact with 
the utility grid.  You must select an AC Profile during setup, regardless of whether grid power will be used.   
To decide which AC Profile to use, see page 5. 

After the initial setup, you can access the wizard by logging in as 

Installer

 and navigating to the 

Configure

 

menu on the 

System

 tab.
