Solar Batteries Canberra
SunBuilt Solar is a certified Sigenergy installer based in Canberra, designing and installing SigenStor home and business battery storage systems across the ACT and surrounding region — Tuggeranong, Belconnen, Gungahlin, Woden, Weston Creek and Queanbeyan included.
SigenStor is an integrated home energy system that combines a solar hybrid inverter, a battery pack, an EV DC charging module and an embedded energy management system into a single unit. Rather than bolting a separate battery onto an existing inverter, every part of the system is engineered to work together — installed, commissioned and supported end-to-end by our local Canberra team.
As your local NETCC-approved solar retailer, we handle the full project: site assessment, system design, Evoenergy grid approvals, install, commissioning and ongoing service. No subcontractors, no “we’ll get back to you”.
Why Canberra households choose SigenStor
- One integrated system: solar inverter, battery, EV DC charger and energy management combined — fewer boxes on the wall, one warranty, one app.
- Backup power through Canberra winters: sized correctly, SigenStor keeps your essential circuits running during grid outages — useful when ACT storms knock out power lines.
- Scalable from 8 kWh upward: stackable battery modules let you start with what you need today and add capacity later — ideal for households that will adopt an EV in the next few years.
- V2H / V2G ready: SigenStor's integrated DC charging module is designed for bi-directional EV charging, so your electric vehicle can eventually power your home — important for future-proofing Canberra installs.
- Installed and serviced locally: every install is done by our CEC-accredited team out of our Dickson office — same technicians for install, warranty and ongoing support.

Our Canberra-based crew installs and maintains SigenStor systems right across the ACT. We're typically on a site somewhere in Tuggeranong, Belconnen, Gungahlin, Woden, Weston Creek, Inner North, Inner South, the Molonglo Valley or Queanbeyan every week — so quotes, installs and warranty visits don't get bumped to a distant service partner.
SunBuilt Solar is a NETCC-approved solar retailer, CEC-accredited and a certified Sigenergy installer. If you'd like a fixed-price quote, a battery size recommendation based on your last 12 months of bills, or a feasibility check against your existing solar system, get in touch with our Canberra team.
Frequently Asked Questions
Can SigenStor be installed on my existing solar system in Canberra?
In most cases, yes. SigenStor's hybrid inverter can replace your existing solar inverter, so your current panels keep producing while battery storage and (optionally) DC EV charging are added at the same time. We do a site assessment first to confirm panel string compatibility, switchboard space and Evoenergy approval requirements before quoting.
