A stackable all-in-one system built around the Energy Controller, with an optional DC EV charging module. *Sizes from 18 to 54 kWh shown in SolarQuotes' comparison. Rated by SolarQuotes installers among the top battery brands in 2025.
Sigenergy SigenStor supplied and installed by our SAA accredited installers across Queensland.
SigenStor is a stackable "5-in-1" system. A solar inverter, a battery power conversion system (PCS), LFP battery modules, an energy management system and an optional DC EV charging module all stack into one tidy tower. Sigenergy rates it IP66, quotes 100% depth of discharge, and says an installation takes around 15 minutes.
How it works, simply: during the day, surplus solar charges the battery instead of being exported for a few cents. In the evening the battery powers your home before you draw from the grid. LFP (lithium iron phosphate) chemistry is known for thermal stability and long cycle life.
It suits new solar-plus-battery installs where you want room to grow, and homes planning an EV: the optional 25 kW bidirectional DC charger module is designed to be V2X-ready.
For Queensland conditions: the manufacturer specifies an operating range of -20 ~ 55 °C, and its enclosure rating is Indoor/outdoor (IP 66). In hot climates many systems reduce output at the top of their range, so we install out of direct afternoon sun with clearance for airflow wherever possible. With storm season bringing outages, the backup set-up (which circuits stay on) is something we'll design with you.
Countryside Solar supplies and installs the Sigenergy SigenStor across Toowoomba, Dalby and our 13 service areas in Queensland. Our SAA-accredited installers handle system design, installation, commissioning and warranty registration, and the work is backed by our 25-year workmanship warranty.

The inverter, battery PCS, batteries, EMS and optional DC EV charger share one footprint, with no messy cabling between modules.
Battery modules stack on the Energy Controller. SolarQuotes compares sizes from 18 to 54 kWh.
Sigenergy specifies 0 ms load-side switchover, so essential loads stay up when the grid drops.
Monitoring and control of solar, battery and EV charging sit in one app, with AI-assisted energy management.

Products from other categories that work well alongside the SigenStor.
Yes. Sigenergy offers an optional DC charging module that stacks into the system. Sigenergy specifies 25 kW bidirectional DC charging that is V2X-ready, subject to vehicle compatibility.
The manufacturer warranty is 10 years, with battery capacity remaining at end of warranty: 70%; warranted throughput: 106,720. Terms may require product registration. We register it for you.
The manufacturer lists Indoor/outdoor (IP 66). In Queensland we still avoid direct afternoon sun where possible, because heat can reduce performance, and we'll recommend the best spot during the site visit.
Eligible installations may qualify for the Cheaper Home Batteries Program discount. We'll confirm eligibility and the current amount in your quote.
Most Queensland homes suit 10–16 kWh of usable storage. We size the SigenStor from your evening usage, backup goals and solar array.
Backup capability varies by model and switchboard design. We'll explain whether the SigenStor covers whole-home or essential circuits for your property.
Often yes via AC coupling or a hybrid inverter upgrade. We assess your current inverter before quoting the SigenStor.
