How the Sigen Hybrid inverter works
The Sigen Hybrid is a 2nd-generation hybrid inverter: it runs your solar array today and manages a battery whenever you choose to add one. It has two MPP trackers, so you can connect panels on two different roof faces and get the best out of each.
When you’re ready for storage, the inverter pairs with the Sigenergy SigenStor BC battery controller and SigenStor BAT battery modules, one to six modules per controller. For instant blackout backup, the system also needs the Sigen Energy Gateway, which switches the backed-up circuits across in 0 ms when the grid drops out.
Choosing the right Sigen Hybrid model
Single-phase (SP2) or three-phase (TP2). Match the inverter to your supply. We confirm this at the site visit.
Sizing to your array. Each model has a maximum DC input (how many panels you can connect) and a nominal AC output (how much it feeds the house and grid). A mid-sized home with 10 kW of panels fits the 5.0 SP2 (up to 10,000 W PV in, 4,999 W AC out), or the 5.0 TP2 if three phase (10,000 W PV in, 5,000 W AC out).
A larger home planning around 13 kW of panels on three phase suits the 8.0 TP2 (up to 16,000 W PV, 8,000 W AC out). If you want the full 10 kW export some three-phase connections allow, the 10.0 TP2 handles 20,000 W of panels and outputs 9,999 W.
If you plan to add a battery later, the inverter size doesn’t change: the Sigenergy SigenStor BC controller fits onto any SP2 or TP2 whenever you’re ready. Pick the inverter for your solar array and household load today.

What installation involves
Site assessment and sizing
We visit the property, inspect the existing solar system and switchboard, and check the space for the inverter. We then recommend a capacity and a location that stays accessible and within temperature guidelines.
Choose your backup circuits
A battery only supplies power in a blackout if it is set up for backup. You choose between essential circuits only and a wider set, and those circuits are wired to the battery.
Installation day
Technicians mount the unit in a shaded, ventilated position, install isolators and route cabling between the array, inverter, battery and switchboard. Every connection is tested before commissioning begins.
Network approval paperwork
The installation is documented and connected to meet Australian standards and Western Power network requirements, with Synergy as the energy retailer. Correct isolators, testing and documentation support meter approval.
Commissioning to standards
Commissioning follows the relevant Australian standards, including AS/NZS 5139 for home batteries. We configure charge and discharge settings, connect monitoring and confirm the system stores and releases energy correctly.
Monitoring app walkthrough
Before leaving, we show you how to read the monitoring app, including battery charge level, solar generation and household usage, and we answer your questions.

Things to know before you buy
Pros
Add a battery later. The hybrid design lets you install solar now and add a Sigen Battery later without replacing the inverter.
Two MPP trackers handle arrays on two roof orientations.
Backup switches over instantly. Switchover to backup takes 0 ms when paired with the Sigen Energy Gateway and a Sigen Battery.
Built for outdoor mounting. The IP66 outdoor rating means it can be mounted outside under cover.
Several ways to connect. Monitoring works over Wi-Fi, Ethernet, RS485 or optional 4G.
Things to consider
The warranty needs an internet connection. Sigenergy’s 10-year cover expects the inverter to stay connected to the internet. We set up monitoring at commissioning and recommend keeping the connection live.
Claims must be lodged quickly. Sigenergy asks for warranty claims to be lodged promptly. If something isn’t right, call us straight away so we can handle it with you in time.
Backup isn’t automatic. Instant blackout backup needs the Sigen Energy Gateway and a Sigen Battery alongside the inverter. Decide at quote stage whether you want backup, and which circuits, so the wiring is right from day one.
Battery add-on uses a specific controller. To connect a Sigen Battery to an SP2 or TP2, the SigenStor BC battery controller is required. We quote the controller and modules together when you’re ready to add storage.
Sigenergy inverter questions Perth homeowners ask
Are Sigen inverters any good?
The Sigen Hybrid is a current-generation inverter with a 10-year warranty and a clear upgrade path to a Sigen Battery later. The monitoring app and the option to add storage later without replacing the inverter are the main attractions.
What size Sigen inverter do I need?
Match the inverter to your solar array and your phase supply. We confirm your phase and array size at the site visit and recommend the model that suits your home.
How much is a 10kW Sigen inverter?
Pricing depends on your switchboard, the install location, and whether you add a battery or EV charger at the same time. We provide a written quote after a site visit.
What are the 3 main types of solar inverters?
String inverters, microinverters and hybrid inverters. The Sigen Hybrid is a hybrid: it runs your solar panels and can also charge and discharge a battery through a battery controller.
Should my solar inverter turn off at night?
A solar-only inverter stops exporting at night because there’s no sun. A hybrid like the Sigen Hybrid keeps managing the household when a battery is connected, discharging stored energy and supplying backup circuits in an outage when paired with the Sigen Energy Gateway.
