Sigenergy's SigenStor is a DC-coupled system that houses the hybrid inverter, battery modules and energy management electronics inside a single stacked cabinet — a cleaner installation, fewer cable runs, and one system to monitor instead of two. It's a Preferred-tier brand in Blue Energy Solar's confirmed range (tier confirmed 14 August 2026), and one we install across Sydney homes.
Quick answer (TL;DR)
- All-in-one DC-coupled hybrid: inverter + battery + energy management in one cabinet.
- Modular ~8kWh stackable modules, from around 16kWh up to well beyond most homes' needs.
- Single-phase and three-phase ranges for standard and higher-demand homes.
- Preferred-tier brand — actively recommended, sized individually to your usage.
- Best for new solar-and-battery installs or full system replacement.
Sigenergy is one of the newer names in Australian solar storage, but its SigenStor platform has moved quickly from launch to widespread installer adoption. Rather than pairing a separate battery with a separate inverter, SigenStor integrates everything into one coordinated unit.
SigenStor is built around stackable battery modules of roughly 8kWh each, mounted onto a base power module that houses the inverter and control electronics. A household can start with two or three modules and stack additional units on top of the same base as needs grow, up to a practical ceiling well beyond what most homes will ever use.
This modularity matters at the quoting stage. Rather than over-specifying on day one, we can size the initial system to current consumption and leave headroom in the cabinet for extra modules later — useful for households planning an EV purchase, a home addition, or simply wanting to test how much storage they actually use before committing further.
The single-phase SigenStor range covers the inverter sizes that suit typical Sydney rooftops and standard household loads, giving most three- and four-bedroom homes enough charging and discharging capacity to run through an evening on stored solar.
For larger homes, homes with three-phase power already installed, or households running heat pumps, pools and EV chargers simultaneously, the three-phase SigenStor range delivers higher inverter output and faster charging, so the battery keeps pace with bigger loads rather than becoming a bottleneck.
We added Sigenergy to our range because the all-in-one design solves a real problem: fewer components on the wall, fewer connection points, and a single manufacturer standing behind the whole system rather than an inverter warranty and a battery warranty from two different companies. The built-in energy management system also handles solar charging, battery dispatch, and backup switching without needing a separate third-party controller.
Because every Sydney roof and household load profile is different, we size every SigenStor system individually using our Quote Wizard and load calculators rather than quoting a generic package.
SigenStor is a DC-coupled system, meaning solar power flows directly into the battery before conversion, rather than being converted to AC and back again. That extra conversion step is where efficiency gets lost in some setups, so a DC-coupled design gets more of the energy your panels produce into storage. It's the natural choice when you're installing new solar and battery together, or replacing an ageing solar system entirely.
If you already have a newer solar inverter you want to keep, an AC-coupled retrofit that connects independently of your existing solar setup is usually the more practical option, and we'll steer you toward the right configuration during your quote.
Sigenergy systems are covered by manufacturer product and performance warranties, and as an accredited Sigenergy installer we handle registration, commissioning, and any warranty claims directly — so if something needs attention down the track, you're dealing with the team that installed your system.
Sigenergy is a Preferred-tier brand at Blue Energy Solar (confirmed 14 August 2026). Its SigenStor platform integrates hybrid inverter, battery and energy management into one cabinet, which we actively recommend for new solar-and-battery installs.
SigenStor stacks in roughly 8kWh modules from a starting configuration up to well over 50kWh, so it scales from a standard home to large, high-demand properties.
DC-coupled, making it best suited to new solar installs or a full system replacement rather than a retrofit onto an existing inverter you want to keep.
