SigEnergy SigenStor
Perth's most advanced modular home battery system
The SigEnergy battery combines a solar inverter, battery storage, EV charging and AI energy management into one expandable system. Supply & install across Perth, WA.
The first true 5-in-1 home energy system
Where most battery systems are add-ons, the SigEnergy battery is purpose-built as an integrated platform. Five technologies share one modular stack — simpler installation, fewer failure points, one app.

Real prices for our three most popular SigEnergy setups — after every rebate, fully installed. Move the sliders to see what you could save and how fast it pays for itself.
Prices are fully installed for a single-storey home with a tin (Colorbond) roof and include the WA & federal battery rebates plus solar STCs (inc GST). Tile roofs and double-storey installs may add cost. Savings are an estimate for a north-facing Perth roof on the Synergy Home Plan (A1), based on using your solar during the day and your battery at night —. Your exact price and savings are confirmed in your quote.
Two government rebates can take thousands of dollars off a SigEnergy battery in Perth, and you can claim both together. We make the whole process simple — here is how each rebate works.
1. WA Government rebate (Synergy)
Synergy customers can claim $130 per kWh of battery storage, capped at $1,300.
To qualify, you join a Virtual Power Plant (VPP): you let the grid use a small amount of your stored energy during peak demand, and you are paid for it. Synergy can do this up to 30 times a year (up to six hours each time), and you can opt out after two years.
2. Federal Government rebate
The federal Cheaper Home Batteries Program cuts roughly 30% off the upfront price of your battery. The rebate is largest on the first portion of capacity and gets smaller as the battery grows. It also steps down every six months, so acting sooner means more savings. Use the slider to estimate yours.
As Perth’s #1-rated solar and battery team, we handle the rebate paperwork for you and make sure you claim every dollar you are entitled to.
Request Your QuoteEstimate only, based on a $38 STC price and May–Dec 2026 rates. Rebate amounts and rules can change, and your final savings depend on your home and system. We confirm the latest figures before you buy. Your battery must be installed after 1 July 2025 and meet the WA Residential Battery Scheme and Cheaper Home Batteries Program rules.

SigEnergy 5 in 1 Modular Battery
Hybrid Inverter
Single or Three phase solar and battery inverter. Converts DC power from your solar panels or battery to usable AC power for your home.
Battery Pack
Scalable lithium-iron phosphate batteries to store your excess solar energy for night time use.
Power Conversion (PCS)
Manages the safe and efficient charging and discharging of the battery modules.
DC EV Charger
A built-in electric vehicle fast charger that allows you to charge your car directly from your solar and battery storage.
Energy Management System (EMS)
The "brain" of the system, which uses integrated AI to optimize energy usage, track consumption, and manage backup power.
A Battery Built for Perth Conditions
Modular & Expandable
Start with one battery module and add more as your needs grow. Up to six modules stack vertically totaling 54kWh, with parallel expansion beyond that. Future-proof your investment.
Blackout Protection
Switches to backup mode in just 5 milliseconds when the grid goes down — fast enough that most appliances won't even notice the interruption. Restores instantly when grid returns.
Integrated EV Charging
The optional DC charger module supports V2X bidirectional charging — meaning your EV can power your home during blackouts. DC fast charge at 12.5kW or 25kW. AC charging at 7–22kW.
AI Powered Monitoring
The mySigen app polls the battery every 10 seconds and shows data down to individual cell voltages and temperatures. AI chat interface lets you control the system conversationally.
Outdoor Rated for Perth
IP66 weatherproof rating and an operating range of -20°C to 55°C makes the SigEnergy battery well suited to Perth's hot summers and outdoor installation locations.

Powerwall 3 is great if you want…
A simple, all-in-one battery from a globally trusted brand, a proven track record, and a straightforward 13.5 kWh size with strong output.
SigEnergy battery is great if you want…
To start smaller and add storage over time, single- or three-phase flexibility, or built-in DC EV charging with V2X — so your car can even power your home.
Still deciding? As a partner of both, we look at your home, your power bills and your plans, then recommend the right fit — with no brand bias.

In Perth, when you use power matters as much as how much. A SigEnergy battery stores cheap solar energy and runs your home when grid power is most expensive. Here is how it works with the main Synergy plans.
Home Plan A1
One flat rate, all day.
Midday Saver
Time-of-use rates.
- 8.62c super off-peak (9am-3pm)
- 23.69c off-peak (9pm-9am)
- 53.84c peak (3pm-9pm)
EV Add-On
Adds a cheap overnight window for charging.
- 19.38c EV window (11pm-6am)
- 8.62c super off-peak (9am-3pm)
- 23.69c off-peak (6am-9am, 9pm-11pm)
- 53.84c peak (3pm-9pm)
What a kWh costs across the day
Tap a plan to see its price through the day.
A1 (most homes) is one flat rate all day. On a time-of-use plan like Midday Saver, a battery charges when power is cheap and runs your home through the 53.84c evening peak.
Storing beats selling
Exporting pays cents. Using your own stored power saves dollars — one of the biggest reasons a battery pays for itself. On a time-of-use plan like Midday Saver it is even higher, up to 53.84c at peak.
Why? Synergy’s feed-in scheme (DEBS) pays just 2c for exported solar (10c in the 3–9pm peak), on the first 50 units a day — so using your own power is worth far more than selling it.
Important: you only receive the DEBS feed-in if your inverter is 5kW or less. Above that, no feed-in at all — which is exactly when a battery matters most.
The bottom line: a SigEnergy battery means you buy less power from the grid and rely less on tiny feed-in rates — and we model your exact numbers for you.
