SP PRO Grid Fail - Generator Backup Kit 

Installation Note 

Introduction 

This installation note details the addition of the Grid fail-Generator backup kit to the SP PRO 

inverter.  The kit is only suitable for the small range (SPMC) of SP PRO AU or GO series (Series 
II) in a single phase or a three phase Advanced Multiphase Solar Hybrid installation. 

 

NOTE

Three kits are required for a three phase Advanced Multiphase Solar Hybrid installation.

 

 

The Grid fail - Generator Backup ONLY operates with Auto Start generators and CANNNOT BE 

USED with manual start generators. A three phase generator must be used in a three phase 

installation.

 

 

When the Grid fail-Generator backup kit is installed into the SP PRO, the system allows for the 
connection of an auto start backup generator that is automatically started and stopped by the 

SP PRO as required during a grid outage.

Preparation

 

 

When installing a single phase system, make sure one Grid Fail Generator Backup kit (005268) is 
on site. 

 

When installing a three phase Advanced Multiphase system, make sure three Grid Fail Generator 
Backup kits (3 x 005268) are on site.
