What Is the Sigenergy SigenStor?
SigenStor is a 5-in-1 home energy system that integrates several functions into a single platform. Instead of purchasing a separate inverter, battery, charger, and controller, homeowners can have a solar inverter (available in hybrid, single-phase, or three-phase configurations), LiFePO₄ battery modules, a battery power conversion system (PCS), an energy management system (EMS) with AI-assisted scheduling, and an optional EV DC charger. By combining these components into one system, SigenStor reduces the number of boxes, cable runs, and overall footprint while providing a single warranty relationship.
The integrated design also allows solar energy to remain in DC form as it moves from the roof to the battery and, when using the EV charger, to the car, reducing some of the double conversion associated with AC-coupled systems.
Sigenergy Company Overview
Founded in 2022 in Shanghai by Tony Xu, formerly head of Huawei’s solar division. It launched SigenStor in Australia in late 2023, has a local office in Sydney, and has since become one of the country’s best-selling home battery brands.

Battery Modules — Sigen Battery Series (BAT 5.0 / 6.0 / 8.0 / 10.0)
The battery is sold as individual stackable modules. Each module has its own internal DC-DC optimiser, so modules of different capacities, ages or states of health can be mixed in the same stack without the weakest module limiting the rest — a genuine advantage over traditional single-string battery packs.

Hybrid Inverter — Sigen Energy Controller (EC) Series
The Energy Controller is the inverter, battery management interface and AI-driven energy optimiser in one unit. It’s available in single-phase and three-phase ranges to suit different property types.
Single-phase Energy Controller (SigenStor EC SP):
- Power ratings across the range: 5kW, 6kW, 8kW, 10kW AC (regional SKUs also extend to 12kW)
- 2, 3 or 4 MPPT solar inputs depending on model, supporting DC oversizing for maximum solar harvest
- Max efficiency up to ~97.8%
- Near-0ms backup switchover when paired with the Sigen Energy Gateway
- Suited to single-phase residential connections
Three-phase Energy Controller (SigenStor EC TP):
- Power ratings across the range: 5kW, 10kW, 15kW, 25kW AC (extending up to ~30kW on some regional models)
- 2–4 MPPT solar inputs depending on model
- True 3-phase asymmetric output — can direct more power to a single heavy-load phase rather than splitting evenly
- Suited to larger homes and small-to-medium commercial sites on 3-phase power
Warranty: 10 years on the Sigen Energy Controller.
EV Charging — Sigen EV DC Charging Module
- Enables direct DC charging from solar/battery to an EV, bypassing the extra AC/DC conversion step of a standard wall charger
- Reduces conversion losses compared to charging via a separate AC EV charger
- Integrates into the same SigenStor stack and is managed through the mySigen App and EMS
- Warranty: 3 years on the EV DC Charging Module (shorter than the 10-year battery/inverter warranty — worth flagging to customers)

Why the SigenStor
- Lower electricity bills — store cheap daytime solar and use it at night instead of buying back from the grid
- Backup power during blackouts — fast switchover (near-0ms with Energy Gateway) keeps essential circuits running
- Energy independence — less exposure to rising grid and time-of-use tariffs
- Eco-friendly storage — 100% depth of discharge and 10,000-cycle cells maximise the useful life of stored solar energy
- Mix-and-match modules — the per-module DC-DC optimiser means older and newer modules, or different capacities, can share a stack without one weak module dragging down the rest
- Built to grow with you — add modules later without replacing the inverter or existing battery stack
- 3-phase and commercial ready — Energy Controller options scale to 25–30kW+ AC for larger sites
FAQs
What’s the difference between the SigenStor BAT 5.0, 6.0, 8.0 and 10.0?
They’re different-capacity battery modules in the same product family — 5.2, 5.84, 7.8 and 8.76 kWh usable respectively. All use LiFePO4 cells rated for 10,000 cycles and can be mixed within a single stack.
What are the Sigenergy battery dimensions?
Each battery module measures 767 x 270 x 260 mm. A 6-module residential stack reaches roughly 1,720mm in height, 850mm wide and 260mm deep (with covers).
Is Sigenergy available in 3-phase?
Yes. The Sigen Energy Controller three-phase range spans roughly 5kW to 25–30kW AC, suiting larger homes and small-to-medium businesses on 3-phase power.
How many battery modules can I stack?
Up to 6 modules per stack residentially (up to ~48kWh with BAT 8.0 modules), and multiple stacks in parallel for commercial sites.
How much does a Sigenergy 8kWh battery cost in Australia?
Cost depends on the battery model, Energy Controller size, and current rebate tier. The federal rebate typically reduces installed cost meaningfully — a personalised quote gives the most accurate figure.
What warranty does the SigenStor come with?
10 years on the battery modules and the Energy Controller, and 3 years on the optional EV DC Charging Module.
