Finn's Sigenergy Inverters Review & Verdict

Finn Peacock has been a Chartered Electrical Engineer since 1998, and is ex-CSIRO

Although new to the Aussie market (launched in 2024), I've been impressed with what I've seen from Sigenergy. 

Their app is the only solar/battery/home energy monitor that is as good as Tesla's. Their commissioning takes minutes. The backup, including 3-phase, is seamless.

Installers really like the hardware and their Aussie support is prompt.

Highly recommended, despite the lack of a long track record in Australia.

Sigenergy Inverters: Pros & Cons

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.

To my knowledge this is the first CEC registered 10kW Inverter to integrate battery/Solar/Inverter management combined with "behind the inverter" 25kW DC Fast charger and bidirectional charging that does not detract from the 10kW 240V delivery.

Regarding the inverter's performance, it has been operating consistently and as expected since installation. Its reliability has been satisfactory, with no reported issues to date. Overall happiness with the inverter is positive, as it effectively fulfills its intended function within the solar energy system.

It’s still early days, but so far, we’re very happy with how the system is performing. The app is user-friendly and provides all the essential information on the home screen, making it easy to monitor our system at a glance. It took a little more time to explore the more advanced features, but since the main dashboard covers everything we need, we could take our time getting familiar with the deeper functions.

We are just a few days in, but I can tell you that this is a quality system. Today we are fully off grid (so running the house entirely from the PV array and disconnected from the grid). We have experienced the 0ms failover from Grid to PV and had no power outages whatsoever when we switched over. Modems and everything stayed online. Our DC EV charger works a treat to .... we just simply tell it to use the excess solar for charging and of it goes direct from the PV array.
