Managed AC Coupled Preparation

For full installation details see document “IN0018_xx SP PRO KACO Managed AC Coupling Installation

Notes” and SP LINK “Site Configuration Wizard”. available from the enclosed USB stick or the Selectronic

Web site: www.selectronic.com.au

The SP PRO KACO Managed AC Coupling provides a method of linking the KACO Powador xx00 and

Powador xx02 series grid tie inverters to the SP PRO via the AC Load supply so that regardless of whether the grid or a generator is connected, the SP PRO can manage and control the KACO grid tie inverters.

Each SP PRO can manage a maximum of five KACO grid tie inverters by commanding each grid tie inverter to output the right amount of power that is needed to simultaneously supply the load, export any excess and maintain the battery bank at any particular point in time. This is done via a communications link which also serves to retrieve all the operational data for display and logging by the SP PRO.

Communications between SP PRO and KACO inverters

The RS485 Communications links between the SP PRO and KACO Powador inverters can be either wired link (using CAT 5 cable) or a wireless link (Using the Optional Selectronic wireless RS485 link, stock code

005075). See diagram below for basic communications wiring

Line diagram for single phase managed AC coupling

The below diagrams detail the AC wiring requirements for Managed AC coupled systems.

Please note that when a Solar Hybrid, Managed AC coupled system is installed with an existing grid connected PV system that has another brand of grid inverter (generic grid inverter) then the generic inverter is connected on the grid side of the system (See diagram below). If there is no existing grid inverter then ignore the grey wiring on the diagram below.

The table above shows the following:

1. The maximum combined AC output of all the KACO inverters in the system for a particular SP PRO model.

2. The minimum battery capacity, at the C10 rate, allowed when the maximum combination of AC output of all the KACO inverters is used.

3, 4. The minimum battery capacity. at the C10 rate, allowed for a particular SP PRO model and the maximum combined AC output of all the KACO inverters in the system allowed when using this minimum battery capacity.

Note: The Minimum battery capacity between 2 and 3 can be calculated using the Site configuration Wizard in SP LINK or using the formula:

Min Batt AH = (Max KACO AC Output) * 1920 / (Battery Volts).

Generic AC Coupled Preparation

For full installation details see document “IN0034_xx SP PRO Generic AC Coupling installation notes” and

SP LINK “Site Configuration Wizard”. available from the enclosed USB stick or the Selectronic Web site: www.selectronic.com.au

To successfully install a SP PRO generic system, there are particular system requirements that need to be met. (See “ “IN0034_xx SP PRO Generic AC Coupling installation notes” for more detail)

• Combined maximum AC output of all the connected generic inverters must not exceed the continuous SP PRO output power rating.

• Battery bank must be sized to suit the SP PRO model and the combined maximum AC Output power of the generic inverters.

• SP PRO generic AC coupling is only suitable for grid connected systems.

• SP PRO generic AC coupling cannot control any grid export limits.

• The Grid Disconnect function in the Solar Hybrid Control should not be used.

The above diagram outlines the AC wiring for a SP PRO Generic AC coupled system

Three Phase Preparation

Installing a three phase system using three SP PRO inverters requires the following optional Kit:

Stock code: 004775 Description: Gx Multi-Phase Pack series II - Available from a Selectronic Distributor.

For detailed information on preparing for a Three phase installation please refer to the document “IN0016_xx

SP PRO Three Phase Installation” found in the Gx Multi-Phase Pack series II, on the USB stick supplied with this inverter or on the support page of the Selectronic web found site at www.selectronic.com.au.

Split Phase Preparation

A split phase system is suitable for connection to a 480V split phase grid supply that is commonly found on

Single Wire Earth Return (SWER) line feeds.

Installing a split phase system using two SP PRO inverters requires the following optional Kit:

Stock code: 004775 Description: Gx Multi-Phase Pack series II - Available from a Selectronic Distributor.

For detailed information on preparing for a Split phase installation please refer to the document “IN0033_xx

DC couple Charge Controller Preparation

Before a DC coupled (charge current fed directly to the battery bank) renewable energy charge controller is installed and integrated into the system the following requirements must be adhered to:

•All DC coupled charge sources must be fed to the battery bank via an optional current shunt.

•All DC coupled charge controllers must have either an output that is activated when the charge controller reaches float OR an input that triggers the charge controller to a float charge state.

Failure to install a current shunt or charge stage linking will reduce the performance and result in non

-optimal operation of the system.

For more detail on installing and integrating a DC charge controller refer to the relevant document in the table below All documents found on the USB stick supplied with this inverter or on the support page of the
