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