Perth solar and battery design
Sigenergy Solar, Battery & Backup Systems Perth
Sigenergy is an integrated solar and battery platform for Perth homes and selected businesses, combining compatible solar inverter, modular battery storage, energy management, backup hardware and EV charging options. Australis Solar designs and installs each Sigenergy system around your Synergy bill, roof, shading, switchboard, energy use, blackout priorities and future EV plans.
Your proposal identifies the exact controller, battery capacity, backup equipment, switchboard work and installation scope. A generic package is not assumed to suit every property.
Who the platform is for
Is Sigenergy right for your Perth property?
The platform may suit customers who want solar generation, battery storage, monitoring, optional blackout support and future EV charging considered as one coordinated energy system. Suitability depends on your existing equipment, electricity use, property and required outcome.
New energy system
Solar and battery designed together
A new system can coordinate the solar array, energy controller, modular storage, monitoring and any required backup equipment from the beginning. This can reduce compatibility compromises and provide a clearer pathway for future expansion.

Integrated system architecture
How the Sigenergy SigenStor platform fits together
SigenStor can bring solar conversion, modular battery storage, energy control, monitoring, compatible backup hardware and selected EV charging options into one coordinated platform. The components included depend on the property and the system design accepted by the customer.
Energy controller
Manages solar conversion, battery operation and energy flow. Controller capacity and phase configuration are selected around the proposed solar array, battery output and network requirements.
Modular battery storage
Battery modules can be combined to provide different storage capacities. Useful sizing considers solar surplus, evening demand, overnight use, reserve settings and future loads.
Sigen Gateway
A compatible Gateway may be included where blackout operation is required. The supported circuits, available output and installation scope must be assessed before backup is promised.
mySigen monitoring
The app can display solar production, household consumption, battery charge and grid interaction. Monitoring accuracy also depends on correct metering and commissioning.
EV charging integration
Compatible EV charging can be considered alongside solar and battery operation. Charger type, vehicle compatibility, electrical capacity and expected charging schedule still need to be confirmed.
Product models, specifications and compatibility can change. The accepted proposal should identify the exact approved equipment being supplied. Review the official Australian SigenStor information for current manufacturer documentation.
Capacity and configuration
Sigenergy battery sizes and design pathways
Battery capacity should be based on how much surplus solar is available, when the property uses electricity, the required overnight buffer and any backup reserve. Australis Solar does not recommend capacity from the Synergy bill total alone.
| Planning capacity | May suit | Assessment considerations | Important limitation |
|---|---|---|---|
| Approximately 9 kWh | Lower evening use, a compact storage objective or a staged battery pathway. | Typical overnight consumption, solar surplus, seasonal variation and minimum reserve. | May provide limited duration where large appliances or backup loads operate together. |
| Approximately 18 kWh | Higher evening and overnight demand, larger solar systems or a more substantial operating buffer. | Ability to charge the battery regularly, inverter output, backup expectations and future EV use. | Additional energy capacity does not automatically increase the inverter’s available power output. |
| Approximately 27 kWh | High-use households, larger properties, regular overnight loads or future electrification planning. | Daily energy demand, available roof generation, winter production, battery location and intended reserve. | The system should still be capable of charging and cycling the installed capacity effectively. |
| Larger configurations | Selected high-demand homes and business applications requiring a project-specific design. | Phase arrangement, controller compatibility, parallel equipment, electrical infrastructure and network approval. | Larger capacity and output are subject to equipment limits, installation requirements and approval. |
These are planning examples rather than guaranteed product packages. Current module capacity, total energy, usable energy, controller compatibility and maximum stack configuration must be confirmed in the proposal. A larger battery can provide more overnight buffer and reduce the depth of regular cycling, but it should still be practical to charge and use.
New solar and battery
Panels, controller, storage and monitoring are designed together around the usable roof area and household load profile.
Existing-system upgrade
The existing inverter and array are assessed before deciding whether they should be retained, replaced or incorporated through another architecture.
Designed blackout support
Gateway hardware, battery reserve, inverter output, phase arrangement and priority circuits are considered as one backup design.
EV-ready energy system
Solar generation, battery operation, charger selection and switchboard capacity are coordinated around the expected charging pattern.

Backup and EV system design
Sigenergy backup and EV charging must be designed together
Battery capacity describes how much energy can be stored. It does not by itself confirm the power available at one time, which circuits remain operating during an outage or whether an EV charger is compatible with the property, vehicle and wider electrical system.

Sigenergy FAQs
These answers provide general guidance. The accepted proposal and current manufacturer, network and scheme documentation determine what applies to a particular installation.
What is Sigenergy and how does SigenStor work?
Sigenergy is an energy technology manufacturer, and SigenStor is its integrated solar and storage platform. A configured system can combine a solar energy controller, modular battery storage, energy management, monitoring, compatible backup equipment and selected EV charging options. Not every installation includes every component.
Can Sigenergy be added to an existing solar system?
It may be possible, but the correct design depends on the existing inverter, panels, array configuration, system age, phase arrangement, metering, switchboard and required battery function. Australis Solar assesses whether the existing equipment should be retained, replaced or incorporated through another compatible architecture.
What size Sigenergy battery should I choose?
Useful capacity is based on surplus solar generation, evening and overnight consumption, backup reserve, inverter output and future loads such as EV charging. Approximately 9 kWh, 18 kWh and 27 kWh configurations may suit different usage profiles, but the exact current module and usable capacity must be confirmed in the proposal.
Will a Sigenergy battery power my home during a blackout?
Not automatically. Blackout operation requires compatible backup equipment, including an appropriate Sigen Gateway configuration, plus compliant isolation and switchboard design. The circuits and appliances that can operate depend on available inverter power, battery charge, surge loads, phase arrangement and which loads run at the same time.
Can a Sigenergy system charge an electric vehicle?
Compatible EV charging can be incorporated into selected system designs. The appropriate charger and operating strategy depend on the vehicle, electrical supply, available solar, battery settings and normal charging schedule. Vehicle-to-home and vehicle-to-grid functions depend on compatible vehicles, standards, approvals, software and product availability and should not be assumed.
Is Sigenergy eligible for the WA battery rebate?
Eligibility is not automatic and should be confirmed before accepting a proposal. It can depend on the customer, installation date, selected product, approved equipment list, installer requirements, available scheme capacity and current Virtual Power Plant or Battery Rewards conditions. Rebates and finance are not guaranteed until all applicable requirements are satisfied.
Review the current Synergy scheme information and the Clean Energy Council approved battery list .
Has there been a Sigenergy product recall?
Yes. A voluntary recall announced in November 2025 applied to specified 8 kW, 10 kW and 12 kW single-phase Energy Controllers using the affected quick-connect AC plug. The approved replacement design uses an OT terminal-style connection. A current proposal should identify the exact model being supplied, while an affected legacy unit should be handled through the official recall process.
