About Sigenergy

What is the Sigenergy SigenStor?

SigenStor is a modular home battery system made by Sigenergy. Sigenergy calls it a 5-in-one system: solar inverter, battery inverter, battery pack, energy management and an optional DC EV charger in one stack. The core is the SigenStor energy controller, a hybrid inverter with 2 to 4 solar inputs. In Australia it comes in single phase from 5 to 12 kW and three phase from 5 to 30 kW.

Storage comes from stackable LFP battery modules. The current SigenStor BAT 10.0 module holds 9.04 kWh, and one energy controller takes 1 to 6 modules, so a single stack reaches 54.24 kWh. A Sigen Energy Gateway adds backup switching for outages. The SigenStor EVDC module adds a DC EV charger to the same stack.

SigenStor is made by Sigenergy Technology Co., Ltd., whose factory is in Pudong, Shanghai. Sigenergy Australia Pty Ltd imports it and is the local warranty contact. The modules join through guided connectors that plug together as they are stacked. The stack stands on the floor or mounts on a wall, indoors or in a sheltered outdoor spot. Sunbridge Energy installs SigenStor as a Sigenergy Certified Installer for 2026.

In Sunbridge’s eyes

Sigenergy review: an installer’s view

Sigenergy Technology Co., Ltd. makes SigenStor at its factory in Pudong, Shanghai, and Sigenergy Australia Pty Ltd, in Sydney, is the local importer and warranty contact. SigenStor folds a solar inverter, battery inverter, battery modules, energy management and an optional DC EV charger into one stackable “5-in-1” tower.

  • True 5-in-1 integration , solar inverter, battery inverter, battery modules, energy management and optional DC EV charging in one stack.
  • LFP modules with a 10-year warranty on the battery and energy controller: 70% of usable energy at 10 years, or 33.29 MWh per BAT 10.0.
  • Highly modular , 1 to 6 BAT 10.0 modules (9.04 kWh each) per controller, up to 54.24 kWh, with EV charging addable later.
  • DC EV charging at 12.5 or 25 kW; Sigenergy says V2X depends on the vehicle and will arrive by over-the-air update once standards are published.

Warranty & compliance
  • Sigenergy warrants the SigenStor battery modules and energy controller for 10 years in Australia, for systems installed on or after 1 November 2023. The Sigen Energy Gateway carries 5 years, the EV DC charging module 3 years and the Sigen power sensor 2 years.
  • The performance warranty guarantees 70% of usable energy at 10 years, or a minimum throughput of 33.29 MWh per BAT 10.0 module, whichever comes first. The system must stay connected to the internet; after more than a year offline, cover drops to 5 years from activation.
  • These are the manufacturer’s terms; your guarantees under the Australian Consumer Law apply in addition. Sunbridge registers the warranty on your behalf as part of the installation.
Rebate guidance
  • Battery incentives change over time and depend on the exact battery model, the installation and your household. The federal Cheaper Home Batteries Program requires the battery to be on the Clean Energy Council approved list, and listing alone does not make a household eligible.
  • Where an incentive applies, your Sunbridge quote shows it as a separate deduction, subject to eligibility at the time of installation. Your quote lists the exact battery model so you can check it against the approved list. See our battery rebate guidance for how the current programs work.

What size Sigenergy battery do I need?

Start with the energy your home uses between sunset and sunrise. Your retailer bill, smart meter data or solar app shows it in kWh. Choose a battery whose usable capacity covers that, plus any growth you expect from an EV or electric hot water. The site inspection confirms the size before you commit.

SigenStor capacity is built from battery modules. Our packages use the SigenStor BAT 10.0, which holds 9.04 kWh in total and 9.0 kWh usable. Our 18, 27, 36, 45 and 54 kWh packages are two, three, four, five and six BAT 10.0 modules, named by their usable capacity. One energy controller takes 1 to 6 modules, so six modules is the most a single stack holds. Our single-phase packages use a 10 kW controller from 18 to 45 kWh, plus a 6 kW option at 18 kWh. Our three-phase packages pair 10, 15, 20 or 30 kW controllers, and 54 kWh comes on the 20 or 30 kW models. Each BAT 10.0 has a maximum charge or discharge power of 4.6 kW. You can add modules later, up to six per controller, and Sigenergy says the optimiser in each module lets new modules work alongside older ones. For more than one stack, several SigenStor systems can run in parallel through a Sigen Energy Gateway, within the gateway's power rating.

Can I add a Sigenergy battery to my existing solar?

Yes. Sigenergy supports two ways to add SigenStor to a home that already has solar. The first is to connect your existing panels straight to the energy controller's solar inputs, so SigenStor replaces your old inverter. The second is AC coupling, where your current inverter stays in place and SigenStor stores the solar it would otherwise export. Which one suits you depends on your panels, your inverter, your phase supply and whether you want backup, so we check this at the inspection.

  • Existing panels can run through the energy controller if the strings fit its inputs. Single-phase controllers track 50 to 550 V (600 V maximum). Three-phase controllers track 160 to 1000 V (1100 V maximum). Each solar input takes one string at up to 16 A.
  • AC coupling does not need your old inverter to talk to SigenStor. Sigenergy's retrofit design uses two Sigen power sensors. One reads the old inverter's output for the mySigen app. The other sits at the grid connection point and tells SigenStor to charge from solar that would be exported.
  • Backup with an AC-coupled inverter needs a Sigen Energy Gateway. If the old inverter connects to the gateway's grid port, it shuts down in an outage and only SigenStor supplies the backed-up loads. It can keep running in an outage on the gateway's smart port only if Sigenergy has verified that inverter brand. It cannot connect to the backup port.
  • Match the controller to your supply. Single-phase controllers suit single-phase homes, and three-phase controllers suit three-phase homes. A three-phase controller splits its output across the phases, so a 15 kW unit is rated for 5 kW per phase, or up to 5.5 kW.
  • Sigenergy's retrofit note is written for solar systems with no existing battery. If you already have a battery, we assess it separately. Removing an old inverter is a listed option in our quotes.

What does the Sigenergy price include, and what costs extra?

Sigenergy SigenStor pros and cons

What we tell customers before they choose Sigenergy.

Pros

  • One integrated stack. The hybrid inverter, battery modules and an optional DC EV charger share one tower, managed in the mySigen app.
  • Modular capacity. Each energy controller takes 1 to 6 battery modules, up to 54.24 kWh with BAT 10.0, and modules can be added later.
  • Wide power range. Single-phase controllers run from 5 to 12 kW and three-phase from 5 to 30 kW, with up to 4 solar inputs.
  • Room for more solar. A single-phase controller accepts up to twice its rated output in solar, for example 20 kW of panels on the 10 kW model.
  • Backup option. With a Sigen Energy Gateway and the right backup configuration, Sigenergy rates the switchover at 0 ms on the load side for whole-home or partial backup.
  • Outdoor-rated hardware. The energy controller and battery modules are IP66 rated, and the battery operates from -20 to 55 °C.
  • Warranty covers the visit. Sigenergy’s Australian warranty pays on-site labour, basic travel and ground shipping for a valid claim, not only the replacement part.

Cons and things to check

  • The warranty depends on an internet connection. After 90 days offline the system enters a safe operation mode, and after more than a year offline Sigenergy reduces warranty cover to 5 years.
  • The 10,000-cycle figure is the cell maker's rating, tested down to 60% state of health. The actual warranty covers 70% of usable energy at 10 years or 33.29 MWh of throughput per BAT 10.0 module, whichever comes first.
  • Heavy and site-sensitive. Each BAT 10.0 module weighs 78 kg. Sigenergy's manual asks for a sheltered spot out of direct sun and rain, at least 500 m from salt-air sources such as the seaside. The system also makes noise, so it should sit away from living areas.
  • Extras carry shorter warranties. The Sigen Gateway has 5 years, the EV DC module 3 years and the Sigen power sensor 2 years, against 10 years for the battery and energy controller.
