About Sigenergy
Sigenergy (also written Sigen Energy) makes modular home-energy systems, including batteries, hybrid inverters, a gateway, EV charging and a monitoring app. They suit households that want to add battery capacity later and see detailed monitoring.
It also suits buyers who want blackout backup on selected circuits, where the installation is wired for it. It is less suited to a set-and-forget system with no internet connection, because the warranty leans on the system staying online. The terms expect it to stay connected, so check the current conditions.

Which Sigenergy product do you need?
Use these pointers to narrow it down:
- If you want battery storage with blackout backup and room to expand later, the SigenStor battery.
- If you are starting a new solar-plus-battery system, the Sigen Hybrid Inverter in single or three phase.
- If you want whole-home energy management and smart-load control, add the Home Energy Gateway.
- If you have, or are planning, an EV, add the Sigenergy EV charger and schedule it from solar in the app.

Things to know before you buy
Pros
The battery can grow with you. The modular Sigenergy SigenStor battery can be expanded as your household’s needs grow.
Backup power during blackouts. Blackout protection is available when the installation is wired for backup.
Detailed monitoring in the app. The app shows energy flow diagrams and AI forecasting.
Long cover on the main components. The battery, energy controller and hybrid inverter carry a 10-year warranty, with an extended-warranty option.
Things to consider
The warranty expects the system to stay online. The warranty terms expect the system to stay connected to the internet. Keep your Wi-Fi credentials current and let us know if your internet changes.
Claims should be lodged promptly. Lodge any warranty claim as soon as a fault appears. We set up the app with you at commissioning so the support path is ready if you ever need it.
The system leans on a trained installer. The battery must be installed by a skilled and trained installer to stay under warranty, and repairs by anyone other than authorised personnel void cover.
What installation involves
On-site assessment
We visit the property, inspect the existing solar, and talk through how your household uses power so we can size the Sigenergy system properly and tell you which parts you actually need.
Switchboard and compatibility check
We check the switchboard’s condition, available space and distance to the proposed location, and whether your existing inverter can work with a Sigenergy SigenStor directly or whether a Sigen Hybrid Inverter is the better path.
Backup wiring decision
A battery only supplies power during a blackout if it is wired for backup. We walk you through which circuits would stay on so you can choose essential-circuits backup or leave the system grid-tied only.
Installation day
Our technicians mount the inverter and battery in a shaded, ventilated position, install isolators and route the cabling between the array, inverter, battery and switchboard.
Network approval and commissioning
The installation is documented and connected to meet Western Power’s network requirements, with Synergy as the retailer. Battery commissioning is done to AS/NZS 5139.
mySigen app set-up and walkthrough
We register the system, connect it to your Wi-Fi, set up the app with you, and show you how to read battery charge, solar generation and household usage.
Sigenergy questions Perth homeowners ask
Who is Sigenergy?
Its residential range covers battery storage, hybrid inverters, a gateway, EV chargers and the mySigen app.
Is a Sigenergy battery any good?
Sigenergy SigenStor is modular and expandable, carries a 10-year warranty on the battery and energy controller, and includes blackout protection when wired for backup.
What is the cycle life of the Sigenergy battery?
The published performance guarantee is that SigenStor retains at least 70% of its usable energy for 10 years. The manufacturer does not publish a separate cycle count.
Is it better to have more solar panels or a bigger battery?
If you already export a lot of unused solar during the day, a bigger battery captures that energy for the evening; if daytime generation barely covers daytime loads, more panels usually come first. The app’s forecasting makes this easier to judge after a few weeks.
What is the lifespan of a Sigenergy battery?
The warranted lifespan is 10 years with a 70% usable-energy retention guarantee. Total cover can extend to a maximum of 15 years if an extended warranty is purchased and activated within 12 months of installation.
