Sigenergy in Melbourne: price, warranty, and the 2025 recall explained
Sigenergy's SigenStor is a premium-tier battery on this site, sold as a system with its own energy controller. Here is what it costs in Melbourne, what the warranty says, what the 2025 recall covered, and what Melbourne's network rules mean for it.
Price in Melbourne
| Brand | Battery | Installed, before rebates | After rebates (VIC) |
|---|---|---|---|
| Sigenergy | 10 kWh | $8,800 to $15,520 | $6,280 to $13,000 |
| Sigenergy | 15 kWh | $13,910 to $20,700 | $10,230 to $17,020 |

Installed prices from the same calculator the free assessment uses, at Sigenergy's premium tier, 15% above value tier on the same capacity. The federal discount is the same for any battery of the same usable capacity[1], and Victoria has no state battery rebate open now[2].
What a SigenStor is
Sigenergy describes the SigenStor series as a storage system made up of the Sigen Battery, the Sigen Energy Controller and an optional EV DC charging module[3]. So it is usually sold as a system with its own controller, not added to another brand's inverter. Battery modules in the warranty table range from 5.2 to 8.76kWh usable each[3].
The warranty
Sigenergy's warranty for Australia and New Zealand, for systems installed from 1 November 2023, covers the battery and the energy controller for 10 years and the EV DC charging module for 3. It promises that the battery keeps 70% of its usable energy for 10 years or reaches a minimum energy throughput, whichever comes first: 23.77MWh for a SigenStor BAT 8.0 module[3].
One clause is worth knowing. The warranty starts when the system is installed, activated and registered, or 180 days after it left the factory if that comes first[3]. Ask your installer when the unit on your quote was shipped.
The November 2025 recall
On 20 November 2025 the Clean Energy Regulator reported an electrical safety recall of Sigenergy single-phase 8, 10 and 12kW energy controllers, affecting around 100 inverters. Affected owners are told through the mySigen app, are asked to keep the system online so it can receive a firmware update, and receive a free replacement with an updated AC plug[4].
The recall covered a small number of single-phase controllers, not the battery modules. If you are buying now, ask the installer to confirm the controller on your quote is a current model.
Melbourne's export rules and a battery
In Melbourne the distributor, not the retailer, sets how much a house may export, and it does so at pre-approval, before anything is installed. The rules are changing. United Energy's, CitiPower's and Powercor's connection policies for 2026 to 2031 lower the maximum static export limit to 1.5kW per phase and offer flexible exports of up to 10kW per phase instead[5][6][7]. AusNet assesses most household systems online for up to 5kW of export per phase[8]. Jemena's policy allows it to impose a zero export limit on a new or altered connection where the customer asks, or where exports would be likely to breach technical limits and fixing that would cost more than it is worth, but not where the customer uses a dynamic system it has specified[9].
The tighter the export limit, the more of a sunny afternoon's surplus is worth storing rather than sending out, and there is no minimum feed-in tariff in Victoria to fall back on[10]. That is the Melbourne case for a battery in one line. Your distributor's name is on your bill; ask the installer what limit the pre-approval came back with.
Questions for a Melbourne quote
Which SigenStor configuration and usable capacity, in writing. The controller model, and confirmation it is not affected by the 2025 recall. When the unit was shipped, given the 180-day warranty clause. What export limit your network approved at pre-approval. And whether the price is before or after the federal discount.
