Trigg solar, battery and backup case study
Trigg Solar & Battery Installation with Whole-Home Backup
Australis Solar designed and installed a 13.20 kW solar system for a three-phase Trigg home, then returned months later to integrate 24 kWh of Sigenergy battery storage, a three-phase Sigen Energy Gateway and whole-home blackout backup. The system combines 30 AIKO Neostar 2S 440 W all-black panels, a 10 kW Sigenergy EC 10.0 TP hybrid inverter and 6 TIGO TS4-A-O optimisers.
The original solar design considered average electricity use of approximately 47 kWh per day, available roof space, shading, ageing roof tiles, the three-phase electrical supply and practical cable routes. The later battery and Gateway stage expanded the existing Australis Solar installation to store solar energy and provide whole-home backup during grid outages.
Australis Solar is Perth-based, WA-owned and has operated since 2008, designing, installing and maintaining custom solar, battery, blackout backup and EV charging systems around the actual property, electricity usage and future requirements.

Designed around the property
Customer objective and design considerations
The Trigg project required more than selecting a panel count. Australis Solar had to coordinate household electricity use, three-phase equipment, roof condition, shading, cable access and a later battery installation capable of supporting the home during a grid outage.
Household energy profile
The original system design considered average consumption of approximately 47 kWh per day. That supported a larger 13.20 kW solar design intended to make better use of the available roof space and increase the amount of household demand that could be offset by solar generation.
The later addition of 24 kWh of battery storage created the ability to retain more solar energy for use outside solar-production periods while keeping the original Australis Solar system in place.
Roof condition and access
The solar panels were installed on metal roof sections, but areas of the property also contained ageing tiles that had begun to deteriorate.
Tile removal was still required for access and cable routing. The installation therefore needed to minimise unnecessary disturbance while allowing owner-supplied spare tiles to be used where required and ensuring the completed work remained weatherproof.
Shading and string design
The final 13.20 kW array uses 30 AIKO Neostar 2S 440 W panels with 6 TIGO TS4-A-O optimisers.
The optimisers formed part of the project's shade and string-management strategy rather than applying module-level optimisation across the entire array.
Meter board and cable routing
The meter board is positioned to the left of the front door, with the property supplied underground from the green dome.
The inverter was positioned nearby to keep electrical runs practical and tidy. Surface conduit at the meter board was allowed for where required for a neat and compliant cable route.
Adding battery storage and whole-home backup
Months after the original solar installation, Australis Solar returned to install three 8 kWh Sigenergy battery modules and a three-phase Sigen Energy Gateway at the rear of the home.
The later stage was designed not only to add 24 kWh of battery storage but also to provide whole-home blackout backup. The existing 13.20 kW PV array and Sigenergy hybrid inverter were retained, with additional AC and communications cabling extended to integrate the new equipment into the existing system.
Whole-home backup means the system is configured to support the home's electrical installation during a grid outage, but available power and operating duration still depend on battery state of charge, inverter and battery capability, solar availability and the loads operating at the time.
One coordinated energy system
System design and installed components
The solar array, hybrid inverter, module optimisation, battery storage and three-phase Gateway perform different roles. Together they create the property's solar, storage and whole-home backup system.
30 × AIKO Neostar 2S 440 W All Black panels
The 30-panel array provides 13.20 kW of installed solar-panel capacity. The all-black modules were arranged across the available metal roof sections as part of the property's roof-specific system layout.
Compare solar panels for Perth homesSigenergy EC 10.0 TP three-phase hybrid inverter
The 10 kW three-phase hybrid inverter converts the solar array's DC generation for use within the property's electrical system and provides the compatible architecture used for the later battery integration.
The inverter also forms part of the complete backup design. Its power capability is different from the battery system's 24 kWh energy-storage capacity.
Explore Sigenergy systems in Perth6 × TIGO TS4-A-O optimisers
Six TIGO TS4-A-O devices were incorporated into the array for the project's identified shade and string-management requirements.
The project therefore uses targeted optimiser deployment rather than assuming that every panel requires an optimiser.
3 × Sigenergy 8 kWh battery modules
The later project stage added 24 kWh of stated battery capacity at the rear of the property.
The stored energy can be used outside solar-production periods and forms part of the property's whole-home backup system. Actual outage duration depends on the battery state of charge and household demand during the outage.
Compare solar battery optionsThree-phase Sigen Energy Gateway
The three-phase Sigen Energy Gateway was installed with the battery stage and integrated with the existing 13.20 kW solar system and Sigenergy hybrid inverter.
The Gateway forms part of the electrical architecture that allows the property to operate in a whole-home backup configuration during a grid outage.
Whole-home backup does not mean unlimited power. Available outage performance remains subject to the inverter and battery system's operating limits, battery state of charge, solar availability and the household loads operating simultaneously.
Explore Sigenergy battery and backup designExtended AC and communications cabling
The battery and Gateway were installed at the rear of the house after the original solar system had already been completed.
Additional AC and communications cabling was extended between the existing energy equipment and the new battery and Gateway location to integrate the solar, storage and backup components into one coordinated system.

Problems and Australis Solar solutions
The project required practical installation decisions around roof condition, cable routes, shading and the later addition of battery equipment with whole-home blackout backup. The design was adapted around the actual property rather than forcing the installation into a standard package.
Ageing and disintegrating roof tiles
Challenge
The solar panels were installed on metal roof sections, but fragile tiled areas still had to be accessed and some tiles removed for cable routes.
Australis Solar assessment
The installation method needed to minimise disturbance to deteriorating tiles while still providing access for the required electrical work. The existing project information also records that future roof works had been considered.
Australis Solar solution
Roof access and cable work were carried out carefully, with owner-supplied spare tiles available where replacement was required. The installation works were completed to ensure the roof remained watertight.
Meter-board position and visible cable routing
Challenge
The meter box is located to the left of the front door and the property has an underground electricity supply from the green dome.
Australis Solar assessment
Inverter placement and cable routing had to provide practical access while avoiding unnecessarily long or visually intrusive runs around the front of the property.
Australis Solar solution
The inverter was located close to the meter board. Surface conduit was allowed for at the meter board where required for a neat, compliant route rather than relocating the energy equipment unnecessarily.
Large solar requirement with identified shade and string considerations
Challenge
The system needed to deliver 13.20 kW of panel capacity while accounting for the roof layout and identified areas requiring additional module-level management.
Australis Solar assessment
Panel placement, three-phase inverter architecture and the locations where optimisation was useful were considered together instead of applying one blanket equipment approach across the entire array.
Australis Solar solution
The completed design combined 30 AIKO Neostar 2S 440 W panels with the 10 kW Sigenergy EC 10.0 TP inverter and 6 TIGO TS4-A-O optimisers for the identified shade and string-management requirements.
Adding battery storage and whole-home backup after the solar installation
Challenge
The later project stage needed to add substantial battery storage and provide whole-home blackout backup at a property where the 13.20 kW solar array and three-phase Sigenergy hybrid inverter were already installed.
Australis Solar assessment
The existing inverter architecture, three-phase supply, battery position at the rear of the home, Gateway integration and the AC and communications route between the original and new equipment had to be coordinated as one system.
Australis Solar solution
Australis Solar installed 3 × 8 kWh Sigenergy battery modules and a three-phase Sigen Energy Gateway, extended the required AC and communications cabling and commissioned the system with whole-home backup capability.
Network settings remain property-specific
New or changed grid-connected inverter and battery installations can be subject to Western Power connection requirements. The exact approved export settings and project-specific connection conditions for this Trigg installation have not been supplied, so they are not stated on this case study.

Trigg project questions
Solar, battery and whole-home backup FAQs
These answers relate specifically to the confirmed Trigg installation. A similar Perth property still requires its own solar, battery, backup and electrical assessment.
What was installed at the Trigg property?
Australis Solar initially installed 13.20 kW of solar using 30 AIKO Neostar 2S 440 W All Black panels, a 10 kW Sigenergy EC 10.0 TP three-phase hybrid inverter and 6 TIGO TS4-A-O optimisers. Months later, the system was expanded with 3 × 8 kWh Sigenergy battery modules, providing 24 kWh of stated battery capacity, plus a three-phase Sigen Energy Gateway and whole-home backup.
How was the Sigenergy battery added to the existing solar system?
The existing 13.20 kW solar array and Sigenergy hybrid inverter were retained. Australis Solar installed the 24 kWh battery system and three-phase Gateway at the rear of the property and extended the required AC and communications cabling so the later equipment could be integrated with the original solar system and commissioned for whole-home backup.
Does the Trigg Sigenergy system provide whole-home blackout backup?
Yes. The later Sigenergy battery and three-phase Sigen Energy Gateway installation was configured to provide whole-home backup during a grid outage. This allows the home's electrical installation to be supported by the backup system rather than limiting backup to a small group of nominated circuits.
Does whole-home backup mean every appliance can run without limits during a blackout?
No. Whole-home backup describes the scope of the backed-up electrical installation, not unlimited available power. The appliances that can operate together and the duration of backup depend on inverter and battery capability, battery state of charge, solar generation during the outage and the household loads being used at the time.
Why were 6 TIGO TS4-A-O optimisers used?
The six TIGO TS4-A-O optimisers formed part of the project's shade and string-management design. They were used where required rather than assuming that every solar panel on the property needed module-level optimisation.
How did Australis Solar manage the ageing roof tiles?
The solar panels were installed on metal roof sections, but some ageing tiles still needed to be removed or crossed for access and cable routing. Australis Solar handled these areas carefully, used owner-supplied spare tiles where required and ensured the completed roof work was weatherproofed.
Is a 13.20 kW solar system with 24 kWh of battery storage and whole-home backup right for every Trigg home?
No. A suitable system should be designed around the property's Synergy bill, actual daytime and evening usage, roof area, orientation, shading, inverter capacity, electrical supply, switchboard, battery location, required backup loads and future EV or electrification plans. The Trigg configuration should not be treated as a standard package.
