Most home batteries store energy and release it on a simple schedule. The SigEnergy SigenStor does something different. It learns your household, watches the sky, and reads your electricity tariff. Then it decides for itself when to charge and when to discharge.
This post explains what SigEnergy’s AI energy management actually does. It also covers how the SP and TP variants differ, and looks at the coupling options available.
What “AI Energy Management” Actually Means
The term AI is used loosely across the battery industry. In the SigenStor, it refers to a predictive dispatch system that uses three real data inputs.
- Weather forecasting: The system checks local solar forecasts. If cloud cover is expected in the afternoon, it may hold battery charge overnight instead of using it up in the morning. It knows the afternoon solar top-up will be limited.
- Historical usage patterns: The system learns your household’s energy use over time. It gets to know your regular high-use periods, such as dinner time, morning showers, and evening entertainment. Then it plans its dispatch around them.
- Tariff optimisation: For Perth homes on the Synergy Midday Saver or EV Add-On tariffs, the system times charging and discharging to save you money. It charges during low-cost periods and holds charge back for peak periods.
In practice, you can set up the SigenStor and largely leave it to manage itself. The AI features take a few weeks to fully learn your household. After that, the system’s decisions reflect your actual usage, not a generic household average.
SigenStor SP vs TP: Single-Phase and Three-Phase
SigEnergy offers two SigenStor variants. Both use the same AI energy management platform, LFP cell chemistry, and IP66 weatherproofing. The difference is how they connect to your electrical system.
Positive Energy Solutions stocks both the SP and TP variants. Our team can confirm your electrical connection type during a site assessment.
Backup power during a grid outage matters most for some single-phase homes. For these homes, the Tesla Powerwall 3 is built specifically for whole-home single-phase backup. Read Is the Tesla Powerwall 3 the Right Choice for Whole-Home Backup in Perth for a full breakdown.
Both SP and TP models switch to backup power in under 5 milliseconds during a grid outage. This is fast enough that most appliances keep running without any noticeable break. Many competing batteries switch in 20 milliseconds or more, which can cause sensitive electronics to reset.
Built-In Safety Features
The SigenStor is built with five separate safety systems. These include aerogel thermal insulation between battery cells, which helps contain heat if a fault happens. There is also a built-in fire suppression system. The battery tracks voltage and temperature at the cell level, and it disconnects automatically under fault conditions. The Lithium Iron Phosphate (LFP) chemistry adds a further layer of safety. LFP cells do not reach thermal runaway at normal home temperatures. This makes them far less prone to fire than older NMC or NCA lithium chemistries.
AC and DC Coupling: Both Options Available
- DC coupling: The battery connects directly to the solar array through the SigEnergy hybrid inverter. This is recommended for new installations.
- AC coupling: The battery connects to an existing solar system without replacing the existing inverter. This makes the SigenStor a good fit for households adding battery storage to a system with a non-SigEnergy inverter.
Some households already have a Fronius GEN24 Plus inverter and want to add storage. For these households, the BYD Battery-Box HVM also works with the GEN24 Plus. It is worth comparing against the SigenStor. Read Is LFP Battery Chemistry Right for Perth Homes for a breakdown of the BYD HVM and how it connects to Fronius systems.
V2X: Vehicle-to-Everything Support
The SigenStor supports vehicle-to-everything (V2X) as an optional feature. This lets a compatible EV send stored energy back through the battery and into your home circuits. In a long grid outage, a 60 to 80 kWh EV battery can stretch backup time well beyond the SigenStor’s own 15.6 kWh.
The SigenStor is also fully modular. Each system takes up to six stackable battery modules of 9 kWh each. This gives total storage from 9 kWh up to 54 kWh in a single stack. You can start with the capacity that suits your needs now, then expand the system later without replacing any core parts.
In Western Australia, Western Power network rules currently allow a maximum of three SigenStor stacks on a 10 kW inverter. This gives a practical maximum of 162 kWh for eligible installations.

Frequently Asked Questions
Is the SigenStor eligible for the WA battery rebate and loan?
Yes, when it is installed in a DC-coupled configuration using the SigEnergy hybrid inverter. DC coupling achieves Whole of Site Compliance. This is required for WA rebate and loan eligibility under the Synergy Battery Rewards VPP program. Only the DC-coupled option qualifies for the rebate and loan. See our DC-Coupled vs AC-Coupled Solar Batteries explainer for a full breakdown.
How fast does the SigenStor switch to backup power during a grid outage?
Under 5 milliseconds. This is fast enough that most appliances keep running without any noticeable break. Many competing batteries take 20 milliseconds or more to switch over. This delay can cause electronics to reset or lose their settings during the switch.
Can the SigenStor charge or draw power from my electric vehicle?
Yes. The SigenStor supports Vehicle-to-Everything (V2X) as an optional feature. This lets compatible electric vehicles both receive charge from the battery and, where supported, feed power back into the home. V2X hardware needs vary by vehicle model. Our team will confirm compatibility when you Request Your Quote.
How many battery modules can I add to a SigenStor system?
Up to six stackable modules per stack at 9 kWh each, giving a maximum of 54 kWh in a single-stack configuration. The modular design means the system can be expanded at any point without replacing the inverter or other core parts.
