myGrid Installation Notes

 

Introduction 

myGrid kits provide an easy to install, compliant, Solar Hybrid (On-Grid) or Off-Grid battery 
system.   

These installation notes outline all the processes required to effectively install each of the 

myGrid kit configurations helping the installer to gain the most benefit from using a myGrid kit.  

myGrid Installation Overview 

There are two major parts to each kit:- 

 

SP PRO or SP PRO GO Interactive Inverter Charger 

 

Battery Enclosure including side mounted DC switchbox 

 

 
 
 
 

 
 
 

 
 
 

 
 
 
 

 
 
 

 
 
The battery enclosure is designed to sit on the floor and the SP PRO or SP PRO GO is wall 
mount.  Connection points between these two parts have been designed to allow flexibility in 

positioning to suit many varied locations. 
 
The battery enclosures in the myGrid kit are modular and each section is called a frame.  Each 

frame can hold four myGrid batteries.  The picture above is a two frame battery enclosure plus 
left hand mounted DC Switchbox.  The DC Switchbox contains the main battery circuit breaker 
and the precharge/battery sense circuit breaker under a protective cover and can be mounted 

on either the left hand side or the right hand side of the battery enclosure.
