SP PRO Generic AC Coupling 

Introduction 

A generic grid tie inverter is a grid tie inverter that is not a KACO Powador 02 or 00 series. For 

information on fully managed AC coupling using the KACO Powador 02 or 00 series inverter see 
“IN0018 SP PRO KACO Managed AC Coupling Installation Notes”.  
 

The SP PRO Generic AC Coupling provides a method of linking generic grid tie inverters to the 
SP PRO via the AC Load supply allowing the PV Solar to be available during a grid outage. This 
configuration is only suitable for Solar Hybrid (grid connected) power systems where grid export 

limit is not required. For off grid systems or where full control of the PV solar is required 
(including grid export limit) use SP PRO KACO Managed AC coupling. 
 
This document details the additional steps needed to install the generic system.  The SP PRO 

and generic inverters can be installed as per their individual installation instructions. 
 

Note: This document needs to be read in conjunction with the SP PRO Instruction Manual and 

the appropriate generic inverter Instruction Manual. 

Overview 

The following is an overview of the connections which form part of the AC Coupled installation 

of a generic grid inverter and SP PRO. 
 

 

Note: Maximum Grid inverter AC output current to be not more than SP PRO rating.
