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. There are two backup modes: whole-house backup, where everything stays live, and smart prioritised backup, where only the circuits you nominate keep running so the battery lasts longer.
It also acts as the system’s traffic controller. Communication is handled 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 (up to 12 kW, up to 2 SigenStors) and the HomePro SP-F (up to 22 kW, up to 3 SigenStors). If your home is three-phase, the Home TP is the match (up to 30 kW, up to 2 SigenStors). The three-phase Gateway matters when you have a larger solar array or heavy three-phase loads such as ducted air-conditioning.
Then look at your inverter and battery plans. The Gateway’s rating caps the total inverter power connected to it: 12 kW on Home SP, 22 kW on HomePro SP-F and 30 kW on Home TP. For example, a single-phase Perth home running an 8 kW hybrid inverter and planning two SigenStor batteries fits comfortably on a Home SP. The same home expecting to add a second inverter or a third battery is better off starting on a HomePro SP-F, because it 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 and check the circuits will not overload the Gateway’s AC rating. 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
We start with a site visit. We inspect your existing solar (if any), check the switchboard’s condition and spare space, and agree where the Gateway and battery will sit. The switchboard check matters because the Gateway’s grid and backup wiring runs through it, and any upgrade needs to be scoped at this stage. We also talk through which circuits you want on backup, since whole-house backup and smart prioritised backup are wired differently.
Before install, we lodge the network application with Western Power and Synergy. On install day the technicians mount the Gateway in a shaded, ventilated spot (rear wiring is supported on the Home SP and HomePro SP models, which keeps the cabling tidy), run the cabling, and connect Ethernet so the system is online from day one.
We commission to AS/NZS 5139, configure the backup mode you chose, set up the mySigen app with you and show you how backup behaves. One practical tip: label the circuits you have put on backup inside the switchboard, so anyone in the house knows what will stay on in an outage.
Things to know before you buy
Pros
Instant 0 ms backup on the load side when the grid drops out, so sensitive electronics ride through outages without resetting.
Choice of whole-home backup or smart prioritised backup for selected circuits, so you can match the backup to what you actually need to keep running.
A single enclosure handles the switching: no additional distribution boxes or electricity meters are required, which keeps the switchboard area tidy.
Owners running correctly sized systems report that the whole home can run off-grid during an outage when 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 any firmware updates are received.
You have to choose the right model up front. Home SP is single-phase and rated to 12 kW, HomePro SP-F is single-phase and rated to 22 kW, and Home TP is three-phase and rated to 30 kW. Swapping between them later is a bigger job than adding a battery module, so we size it at quote stage based on your supply and the inverters you plan to run.
Inverter power is capped per model. The sum of parallel inverter power connected to a Home SP cannot exceed 12 kW, a HomePro SP-F 22 kW, and a Home TP 30 kW. If you plan to expand solar later, we size the Gateway now so the future array still fits.
Battery count per Gateway is limited. Home SP and Home TP each support up to 2 SigenStors, while HomePro SP-F supports up to 3. If you expect to grow past that, HomePro SP-F (single-phase) or a parallel setup is the better starting point.
Outdoor placement still needs shelter. The Gateway is rated IP55 and runs across a wide temperature range, but we still 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 also manages switching between solar, battery, grid and generator sources, 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 includes a Fast Ethernet port for wired internet. We run a network cable from your router or a nearby access point to the Gateway during installation, and set up the mySigen app as part of commissioning. 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, Home TP and C60 Gateway models. We install the Australian-model equipment and commission it to the Australian battery standard AS/NZS 5139.
How do I shut down my Sigenergy solar system?
Shutdown is done at the DC and AC isolators that sit alongside your inverter, battery and Gateway. We show you where these are during the app walkthrough on install day, and we recommend only using them for a genuine reason (such as a trade needing to work near the switchboard). For anything beyond a basic switch-off, call us rather than opening the enclosure.
How to open sigenergy gateway?
The Gateway is a sealed enclosure rated to IP55 and is not intended to be opened by the homeowner. Any work inside it has to be done by a licensed electrician, both for safety and to keep the warranty intact. If something is not behaving the way the app says it should, contact us and we will diagnose it.
Should my solar inverter turn off at night?
A solar-only inverter typically goes into standby overnight because there is no sun to convert. With a Sigenergy system that includes a Gateway and SigenStor battery, the inverter and Gateway stay active to discharge the battery to your home and to be ready for any outage. That is normal and expected behaviour.
