How the Sigenergy Gateway works
The Gateway sits between your switchboard and the Sigenergy system. In normal conditions it passes grid power through a built-in bypass circuit and lets the inverter and battery charge, discharge and export as usual. When it senses the grid has gone, it isolates the home from the network and switches the house (or your chosen circuits) onto the battery with 0 ms load-side disruption.
It also acts as the system’s traffic controller. Communication is over Fast Ethernet, RS485 and a dry contact, and a smart load feature can auto-start or stop loads based on the battery’s state of charge. Because the switching and metering are built in, you do not need a separate distribution box or electricity meter alongside it.
Which Sigenergy Gateway suits your home
Start with your supply type. If your home is single-phase, you are choosing between the Home SP and the HomePro SP-F. If your home is three-phase, the Home TP is the match. Three-phase matters when you have a larger solar array or heavy loads such as ducted air-conditioning.
Then look at your inverter and battery plans. For example, a single-phase Perth home with an 8 kW hybrid inverter and two SigenStors fits comfortably on a Home SP. The same home expecting a second inverter or a third battery is better off starting on a HomePro SP-F, which allows up to 3 SigenStors and 22 kW of inverter power on one Gateway.
Finally, decide how much backup you want. If you want everything to stay on during an outage, we size for whole-house backup. If you only need the essentials (fridge, lights, internet, a few power points), smart prioritised backup is often enough and the battery lasts longer per outage.

What installation involves
Site and switchboard assessment
We visit the property and inspect the existing solar system, the switchboard and the proposed location. Any switchboard change needed is raised at this visit, so it is not a surprise on installation day.
Choose your backup circuits
Backup only works if it is wired for it. You choose between essential circuits only and a wider set, and what stays powered depends on battery capacity and how it is wired.
Installation day
Technicians mount the unit in a shaded, ventilated position, install isolators and route the cabling between the array, inverter, battery and switchboard. Every connection is tested before commissioning begins.
Network approval
The installation is documented and connected to meet Australian standards and the requirements of Western Power, with Synergy as the energy retailer. Correct isolators, testing and documentation are provided for meter approval.
Commissioning and testing
Commissioning is done to the relevant Australian standards. We configure the settings, connect the monitoring and confirm the system is storing and releasing energy correctly.
App walkthrough
Before leaving, we show you how to read the monitoring app, explain the display and the aftercare tips, and answer your questions so you understand how the system works day to day.

Things to know before you buy
Pros
Backup switches over instantly. Load-side backup responds in 0 ms when the grid drops out, so sensitive electronics ride through outages without resetting.
You choose how much to back up. Pick whole-home backup or smart prioritised backup for selected circuits, so backup matches what you need to keep running.
One enclosure does the switching. No additional distribution boxes or electricity meters are required, which keeps the switchboard area tidy.
The whole home can run off-grid in an outage. This works when the system is correctly sized and the Gateway is installed and configured for it.
Things to consider
The Gateway warranty is shorter than the battery warranty. Sigenergy covers the Gateway for 2 years, which is less than the SigenStor battery and controller. Plan for that in your budget and keep the system online so firmware updates are received.
You have to choose the right model up front. Home SP is single-phase to 12 kW, HomePro SP-F is single-phase to 22 kW, and Home TP is three-phase to 30 kW. Swapping later is a bigger job than adding a battery module, so we size it at quote stage.
Inverter power is capped per model. Parallel inverter power cannot exceed 12 kW on Home SP, 22 kW on HomePro SP-F or 30 kW on Home TP. If you plan to expand solar later, we size the Gateway now so the future array still fits.
Outdoor placement still needs shelter. The Gateway is rated IP55, but we install it in a shaded, ventilated spot to keep it off direct afternoon sun and extend its service life.
Sigenergy Gateway questions Perth homeowners ask
What does the SIG gateway do?
It manages switching between solar, battery, grid and generator, so you do not need a separate distribution box or electricity meter. Backup modes include whole-house or smart prioritised backup for selected circuits.
How do I connect my Sigenergy SigenStor to an Ethernet connection?
The Gateway has a Fast Ethernet port for wired internet, and we run a network cable from your router during installation. A wired connection is more reliable than Wi-Fi for keeping the system online.
Is Sigenergy a Chinese company?
Sigenergy is a global home-energy brand that supplies the Australian market with its Home SP, HomePro SP-F and Home TP Gateway models. We install the Australian equipment and commission it to AS/NZS 5139.
How do I shut down my Sigenergy solar system?
Shutdown is done at the DC and AC isolators next to your inverter, battery and Gateway, and we show you where they are on install day. For anything beyond a basic switch-off, call us rather than opening the enclosure.
Should my solar inverter turn off at night?
A solar-only inverter goes into standby overnight because there is no sun to convert. With a Gateway and SigenStor battery, the inverter stays active to discharge the battery and be ready for any outage, which is normal.
