Sigenergy
A genuinely integrated 5-in-1 energy platform - solar, battery, energy management and EV charging in one system. Off The Grid specifies and installs SigenStor for homes and businesses across Australia.
One platform. One installer. One less headache.
SigenStor launched in Australia in late 2023 and by mid-2025 was one of the country's top-selling solar batteries. The reason is straightforward: inverter, battery and energy management in one integrated, stackable platform rather than separate components bolted together.
A system this capable needs to be specified and configured correctly to deliver its full value, which is exactly what we do.
Built differently from the ground up
Most storage setups involve multiple brands, multiple platforms and multiple points of failure. SigenStor removes that. Hybrid inverter, battery modules, energy management and optional DC EV fast charger are engineered as a single unit, fewer compatibility issues, faster commissioning, one monitoring view instead of three apps.
The mySigen platform uses AI-assisted scheduling to manage charge and discharge cycles around your tariff structure and generation profile automatically. It also supports V2H and V2G, so compatible EVs can act as additional storage or feed back to the grid where regulations allow.
Smart home storage that grows with you
SigenStor suits Australian homes that want flexible, future-ready storage - whether you're starting small or building a whole-home energy setup from scratch. Here's what we deliver.
Reduce your evening power bills
We size and configure SigenStor to shift your solar generation into the hours when your household actually needs it most:
- Stores surplus daytime solar and discharges automatically during evening peak tariff windows, reducing what you buy from the grid
- AI-assisted mySigen scheduling adapts to your household usage patterns and tariff structure without needing manual input
- Modular 5-9kWh modules stack per tower - start with what suits your budget today and add capacity as your needs grow
- LFP chemistry delivers stable, safe performance with a 10-year warranty and approximately 70% capacity retention guaranteed
- Quiet, IP66-rated enclosures suit indoor or outdoor installation in Australian conditions year-round
Your evening bills reduce month after month, and Off The Grid keeps the system optimised as your household and tariff structure change over time. See how SigenStor fits into a home solar system.
Keep the lights on when the grid goes down
SigenStor's 0ms transfer time means your home keeps running before most appliances even register a fault:
- Automatic switchover with zero millisecond transfer time - no manual steps, no flickering lights, no reset clocks
- Black-start capability allows SigenStor to recharge from solar during extended outages, extending backup runtime significantly
- Smart load ports let us configure which circuits are protected and in what priority order during your installation
- Storm Guard mode pre-charges the battery to full when severe weather is forecast - prepared before the outage arrives
- Optional integrated DC EV charger module means your home battery and EV charging share one compact footprint
When the grid goes down, your household keeps running - because we designed the backup configuration around your actual critical loads. Explore residential EV charging to see how SigenStor pairs with home EV charging.
Commercial storage that works as hard as you do
For commercial sites juggling solar, building loads and EV charging, SigenStor's integrated architecture is a genuine advantage. Here's what we deliver for businesses.
Cut peak demand charges and grid costs
We profile your site's load data before specifying SigenStor - so the system is sized to move your demand charges, not just to look good on paper:
- Discharges during peak tariff windows to reduce the demand charge spikes that often represent the largest component of commercial electricity bills
- Three-phase output handles unbalanced commercial loads, with smart load ports for prioritising critical circuits
- Scales from tens of kilowatt-hours up to multi-megawatt-hour capacity by paralleling modular towers
- Remote monitoring lets us track performance and adjust charge and discharge settings as your load profile shifts across seasons
- Suits offices, warehouses, retail, hospitality and light industrial sites - any commercial site with meaningful peak demand exposure
Your demand charges reduce on a schedule built around your actual site data, and Off The Grid keeps the system calibrated as your operations evolve. See our full commercial solar battery offering.
Protect critical operations from outages
We design SigenStor's backup configuration around your actual critical load list - not just total site capacity:
- 0ms automatic switchover protects servers, refrigeration, production lines and security systems without manual intervention
- We identify and prioritise your critical circuits during the design phase so backup capacity is matched to what genuinely needs protection
- Black-start capability extends backup runtime during prolonged outages by continuing to recharge from solar generation
- Industrial-grade IP66 enclosures handle Australian commercial environments - plant rooms, rooftops or external wall mounting
- LFP chemistry and multi-layer safety protections meet commercial installation requirements
When the grid fails, the loads that matter to your business keep running - because we built the system around that outcome from the start.
Integrate storage, solar and EV charging in one system
SigenStor's optional integrated 25kW DC EV charger module makes it one of the most compact combined storage and fast-charging solutions available - and Off The Grid handles the full electrical integration:
- DC fast charging built into the same physical footprint as the battery - no separate charger cabinet, no additional switchboard complexity
- Battery storage buffers EV charging demand, preventing fleet charging from pushing the site into a costly grid connection upgrade
- mySigen manages solar, building loads, battery state and EV charging from one interface - not four separate platforms
- Our commercial electricians handle switchboard integration, grid connection compliance and commissioning end-to-end
- V2G-ready architecture means the system is positioned for future grid service participation as regulations evolve
Your fleet charges from stored solar, your grid connection stays within limits, and your team has one dashboard for the whole picture - installed by a single accountable team. Explore our commercial EV charging services.
Only the best brands.
Why the installer matters as much as the system
We configure SigenStor around your site, not a default setting.
The mySigen platform is powerful because it can be tailored - but only if the person commissioning it understands your tariff structure, load profile and solar generation data. That's what our assessment process delivers before a single piece of equipment is ordered.
We handle the full scope.
SigenStor's integration across solar, switchboards and EV charging means the installation touches multiple systems. Our accredited solar installers and commercial electricians manage the entire job under one roof - no handoffs, no gaps in accountability.
We stay involved after switch-on.
Remote monitoring means we catch performance issues early and adjust system settings as your needs change.
SigenStor works best when it's set up right.

Your Questions, Answered
How does SigenStor differ from a standard battery system?
Most setups combine separate components from different brands - a hybrid inverter, a battery bank, an energy management system, and a separate EV charger if needed. SigenStor integrates all five functions into one engineered platform. Fewer compatibility issues, simpler commissioning, and one monitoring interface rather than several.
Can SigenStor be added to an existing solar system?
In most cases, yes. The key considerations are your existing inverter type and whether DC or AC coupling is the better integration path for your site. We assess this as part of our commercial solar battery or home solar battery design process - clear recommendation before any equipment is ordered.
What support is included after installation?
Off The Grid provides ongoing remote monitoring and direct support. If a performance issue appears, we identify it and resolve it - you're not navigating a warranty claim through a distributor.
