Padbury solar & battery case study

Padbury Solar & Battery Installation with Backup

Australis Solar, a Perth-based and WA-owned solar company operating since 2008, first upgraded this Padbury home with a 6.11 kW AIKO solar array and 5 kW three-phase Fronius Symo GEN24 inverter with PV Point backup. Months later, our team returned to add 10.24 kWh of BYD HVS battery storage and a Fronius Back-up Box.

The staged design allowed an ageing solar system to be replaced while retaining a practical pathway for later storage and backup. Roof access, panel placement, existing electrical equipment, the battery position and backup equipment all had to be considered as the project developed.

Designed for the property

Customer objective and design considerations

This project developed in two stages. The first requirement was to replace an ageing 12-panel solar system while dealing with limited roof access and existing electrical work. The later requirement was to integrate battery storage and additional backup equipment with the Fronius-based system already installed.

01

Replace the ageing solar system

The property had an older 12-panel solar installation dating from 2010. Australis Solar removed the previous system and installed 13 higher-capacity AIKO panels with a new three-phase Fronius inverter.

02

Preserve roof access

The homeowner still required access to the roof cavity through the tiled roof. Panel placement therefore had to leave practical access rather than simply filling every available section.

03

Work across the available roof orientations

The confirmed installation used multiple roof areas, including a limited southwest section. The array layout was planned around the available roof geometry while maintaining the required access.

04

Plan for later battery storage

The original Fronius-based solar design was selected with future battery integration in mind. Months later, Australis Solar returned to add 10.24 kWh of BYD HVS storage rather than replacing the recently installed solar array.

05

Confirm a practical battery position

The battery was installed at the front of the property beside the garage. The location of the meter board, battery equipment, Back-up Box and cable route formed part of the retrofit planning.

06

Coordinate electrical and connection requirements

The complete project included meter-board remedial work, commissioning, monitoring and the required Synergy and Western Power connection processes rather than treating the battery as a standalone appliance.

A staged solar and storage system

System design and installed components

The final project combines rooftop solar, a three-phase Fronius inverter, dedicated PV Point backup, BYD battery storage, additional backup equipment and Fronius monitoring. Each component has a different role within the complete system.

Solar generation

13 × AIKO Neostar 2P 470 W panels

The 13-panel array provides 6.11 kW of installed solar capacity and replaced the older 12-panel system.

The array was laid out around the usable roof areas while retaining the roof access required by the homeowner.

Power conversion

Fronius Symo GEN24 5 kW

The three-phase Fronius inverter was installed with the original solar upgrade and provides the power-conversion and monitoring platform for the system.

The later battery project was integrated with this existing Fronius-based installation rather than replacing the recently installed solar array.

Initial backup

Fronius PV Point

PV Point backup was enabled during the original installation to provide a dedicated emergency-power outlet when the required operating conditions are available.

PV Point should not be confused with whole-home backup.

Stored energy

10.24 kWh BYD HVS battery

The later retrofit added four 2.56 kWh BYD HVS modules, providing 10.24 kWh of stated battery capacity together with the required base and battery-management equipment.

The battery allows compatible solar energy to be stored for use later rather than relying only on real-time rooftop generation.

Backup equipment

Fronius Back-up Box

A Fronius Back-up Box was added as part of the battery installation and mounted below the meter board.

The supplied project information confirms backup functionality but does not confirm that every household circuit is backed up, so this case study does not describe the installation as whole-home backup.

Installation infrastructure

Clenergy mounting, electrical work and monitoring

Clenergy rails and racking support the rooftop array. Three switches were relocated and a fire seal was added at the existing meter/distribution board during the original project.

The completed solar and battery installation was commissioned with monitoring enabled through the inverter's WLAN interface and Fronius Solar.web.

Problems and Australis Solar solutions

The value of this project was not simply the equipment installed. The solar layout, existing electrical infrastructure, later battery retrofit and post-installation close-out each required a practical response.

Problem

Roof access limited the available panel area

The homeowner required continued access through the roof tiles, which meant the new array could not simply cover all otherwise usable roof space.

Australis Solar assessment

The team had to balance the required 13-panel layout with roof geometry, different orientations and the access area that needed to remain available.

Solution

The AIKO array was distributed across the available roof areas while preserving practical roof access and retaining the confirmed 6.11 kW solar capacity.

Problem

Existing meter-board work was required

The existing meter/distribution board required a fire seal and three switches needed to be relocated as part of the original solar installation.

Australis Solar assessment

The electrical work had to be incorporated into the installation scope rather than leaving the new solar equipment disconnected from existing board conditions.

Solution

A fire seal was added and the three switches were relocated before the system was completed and commissioned.

Problem

The homeowner later wanted battery storage and additional backup

The battery project occurred months after the original solar installation, so the new storage equipment had to be integrated with the Fronius-based system already operating at the property.

Australis Solar assessment

The existing inverter, three-phase supply, battery location, meter-board position, backup equipment, monitoring and connection requirements all needed to be considered as one retrofit.

Solution

Australis Solar added 10.24 kWh of BYD HVS storage using four battery modules, installed the Fronius Back-up Box and recommissioned the complete system with monitoring enabled.

Problem

A battery terminal cover was delayed by the supplier

The battery installation could not be considered fully closed out until the outstanding terminal/housing cover became available.

Australis Solar assessment

The outstanding supplier item needed to be tracked and completed rather than treated as the homeowner's responsibility.

Solution

Australis Solar kept the homeowner updated and returned once the replacement cover was available to complete the hardware installation.

Problem

The Plenti close-out email appeared suspicious

The customer's first close-out email was poorly formatted and appeared similar to a phishing message, creating a reasonable concern about replying to it.

Australis Solar assessment

The communication needed to be verified before the customer proceeded with the administrative close-out.

Solution

Australis Solar contacted Plenti to have the email reissued. The customer subsequently confirmed receipt and the application process could continue.

WA connection requirements

The project records confirm Synergy and Western Power involvement. Western Power also requires an Embedded Generation Connection application when another generation source such as a battery is added or an inverter installation is changed.

Padbury project questions

Solar, battery and backup FAQs

These answers relate to the confirmed Padbury installation. A similar Perth property still requires its own solar, battery, switchboard and backup assessment.

Why was the battery added after the solar system?

The solar system was installed first using a Fronius-based design that allowed future storage to be considered. Months later, Australis Solar returned to add 10.24 kWh of BYD HVS battery storage and a Fronius Back-up Box to the existing installation.

How much battery storage was installed in Padbury?

The battery installation has 10.24 kWh of stated capacity using four BYD HVS 2.56 kWh battery modules together with the required battery base and BMS.

Does this Padbury project have whole-home backup?

The project scope confirms PV Point backup in the original solar installation and later backup functionality through a Fronius Back-up Box. The supplied records do not confirm that every circuit in the home was backed up, so this case study does not describe the system as whole-home backup.

Where was the BYD battery installed?

The battery was installed at the front of the property beside the garage. The Fronius Back-up Box was mounted below the meter board as part of the battery and backup installation.

What electrical work was completed with the solar installation?

The confirmed original scope included relocation of three switches and installation of a fire seal at the existing meter/distribution board. The system was then tested, commissioned and connected to Fronius monitoring.

Can a battery be added later to an existing solar system?

Often, but compatibility must be checked first. Australis Solar assesses the existing panels, inverter, phase configuration, switchboard, battery location, backup requirements, monitoring and current Western Power connection requirements before recommending a retrofit.
