What the SigenStor includes

Five systems in one unit

Most solar battery systems involve separate components from separate manufacturers bolted together. The SigenStor integrates everything into one unit, which simplifies installation, reduces points of failure and gives you a single system to manage and monitor.

Solar inverter

High-performance hybrid solar inverter with 4 x MPPT inputs. Converts solar generation into usable power and manages charging and discharging of the battery.

Built-in DC EV charger

The only system in our range with a built-in DC EV charger. Supports Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) capability.

Modular battery storage

Stackable 5kWh or 8kWh lithium iron phosphate modules. Up to 6 modules per stack, expandable from 8kWh to 48kWh. Each module operates independently.

AI energy management system

Built-in intelligent energy management optimises how and when your energy is used. Particularly effective with time-of-use tariffs and variable demand patterns.

Whole-home backup

Zero-load disruption switchover. When the grid goes down your home keeps running without any manual intervention.

Safety and durability

Built for North Queensland conditions

5-layer safety architecture

Five independent layers of protection for safe, stable battery operation across the full range of North Queensland conditions.

Built-in fire suppression

Internal fire suppression is built into each battery module, not an optional add-on.

7 temperature sensors per module

Continuous thermal monitoring across every module keeps the system operating within safe parameters in Townsville’s heat.

IP66 rated

Full protection against dust and water ingress. Can be installed indoors or outdoors, suitable for the tropical coastal environment of North Queensland.

Low-voltage design

Under 36V DC design makes it safer for households and families without compromising performance.

Zero-load disruption switchover

Seamless transition to backup power during a grid outage with no disruption to connected appliances.

Who the Sigenergy SigenStor suits

The most advanced home energy system we supply

The SigenStor is the right choice when you want a single system that handles solar, storage, EV charging and backup power without compromise. It is the most capable product in our range and suits homeowners who want to future-proof their energy setup rather than just solve today’s problem.

Best for: EV owners who want to use their car as part of their energy system

The SigenStor is the only system in our range with a built-in DC EV charger and V2H capability. If you drive or plan to drive electric, this integrates your vehicle, your solar and your home battery into one managed system. No separate charger required.

Best for: homeowners wanting maximum control over their energy

The AI energy management system, advanced tariff optimisation including Tariff 12E configurations, generator connection support and Virtual Power Plant capability make the SigenStor the right choice for homeowners who want to actively manage their energy rather than set and forget.

Best for: new installs and retrofits on any existing system

The SigenStor includes its own hybrid inverter and supports both new solar installations and retrofits on existing systems. Whether you are starting fresh or adding storage to panels you already have, it can be configured to suit your setup.

For electric vehicle owners

EV charging, V2H and V2G

The SigenStor is the only system in our range with a built-in DC EV charger. If you drive electric, this integrates your solar generation, your home battery and your vehicle into a single managed system.

Charge your EV from solar

Charge your vehicle directly from your solar generation rather than paying for grid power.

Vehicle-to-Home (V2H)

Your EV can power your home during an outage. Particularly useful in Townsville where storm events can disrupt the grid.

Vehicle-to-Grid (V2G)

Export stored energy from your vehicle back to the grid, with potential to earn credits through Virtual Power Plant programs.

Federal rebate

Cheaper Home Batteries Program

The SigenStor is eligible for the federal Cheaper Home Batteries Program, which provides an upfront discount on the installed cost. The rebate applies to both new solar and battery installs and to retrofits on existing solar systems that do not yet have storage.

The exact rebate value depends on battery size and adjusts periodically. We apply it directly to every quote so you can see your actual cost upfront.
