Company Information 

Founded in early 2022 by ex-Huawei solar division president Tony Xu, Sigenergy hit the ground running and just three years on has more than 600+ employees; the vast majority of which are focused on research and development. 

Sigen Hybrid Inverters

Sigen hybrid inverters can be used in conjunction with a solar power system only, or with solar panels and the SigenStor battery and charger modules. But note that if you add SigenStor energy storage after the inverter module has been installed, you'll need to purchase and activate a licence.

The company's inverters offer up to 4 MPP (Maximum Power Point) trackers, 97.6% conversion efficiency and DC/AC ratio of up to 2. Communications are via WLAN, Ethernet or 4G. 

Sigen inverters are built for tough conditions, with an IP66 rating providing very high resistance to dust, humidity and rain. The inverters have an operating temperature range of -30C ~ 60C. In a country such as Australia, that sort of robustness is a real plus.  

Sigen hybrid inverters are available in Australia in single-phase and three-phase models. Among the single-phase offerings, which measure 700 x 300 x 283 mm and weigh 36 kg, are the:

• 8.0 SP AU: 8.0 kW
• 10.0 SP AU: 10.0 kW
• 12.0 SP AU: 12.0 kW

All of these are on the Clean Energy Council's approved inverter list as at March 2025: a must-have if you want to claim Australia's solar rebate, some state incentives and to get permission to have the system connect to the grid. Other capacities (greater and less than the above) are CEC-approved when installed as part of a full Battery Energy Storage System (BESS).

CEC-approved 3-phase models (5kW, 10kW, 15kW, and 25kW) are also available here when installed as part of a BESS. 

Sigen PV Max

Additionally, CEC-approved non-hybrid single-phase models called "PV Max" in capacities from 3kW to 6kW can be purchased in Australia as well. The PV Max inverters in this range have 2 MPPTs, up to 98% conversion efficiency and an IP66 ingress rating. Sigenergy produces other single-phase units (up to 12kW) and three-phase PV Max inverters (up to 25kW), but as at the time of updating this page, they weren't CEC listed.

Inverter Monitoring

Real-time monitoring is available via the comprehensive mySigen App, which is powered by AI (GPT-4). This could be very attractive to some and a little off-putting to others. According to the company, the AI smarts can help achieve maximum energy bill savings by automatically accessing system operation, dynamic tariffs, and weather data. Owners can instruct the app using a chat feature and also submit support tickets if they encounter issues during system operation directly from within the app. 

Sigen Inverter Warranty

Sigenergy Technology Co., Ltd. warrants that their hybrid inverters will be free of defects caused by improper workmanship or defective materials for a period of 10 years.

Sigenergy is currently a SolarQuotes-approved inverter brand. If you're using a Sigen inverter in Australia, let us know your opinion by leaving a review.
