SolaX inverter Perth guide: X-Hybrid and string range for WA homes
A plain-English guide to SolaX inverters for Perth homes: the X-Hybrid battery-ready range, the X3-MIC string inverters, efficiency, warranty, monitoring, and how SolaX stacks up against Sungrow and GoodWe.
SolaX is a mid-tier hybrid inverter brand you'll see quoted across Perth, usually as the cheaper alternative to Sungrow and Fronius. Its X-Hybrid range is battery-ready, peaks at around 97.6% efficiency, carries a 10-year warranty as long as you register it, and pairs with SolaX's own Triple Power T-BAT battery or a compatible third-party one. It's a credible pick. The one real catch is service depth: fewer Perth installers work with SolaX day to day, so who fits it matters as much as the box itself.
If you already have a quote with a SolaX inverter on it, this guide walks through what you're actually getting: the model ranges, the real efficiency and warranty numbers, how the monitoring works, and where SolaX wins or loses against the brands it's usually compared to.

Who makes SolaX, and should Perth buyers trust it?
SolaX Power is a Chinese inverter manufacturer founded in 2010 and headquartered in Hangzhou. It entered the Australian market in 2015 and now reaches Perth through a network of solar distributors. On a quote, it sits in the same mid-tier bracket as Sungrow, GoodWe, and Growatt: cheaper than Fronius or SMA, more feature-complete than the budget end.
The short answer: SolaX is a credible choice, with the usual mid-tier caveat that your installer relationship carries more weight than the brand badge. For where SolaX sits among the inverter formats, see our Perth inverter types overview.
Which SolaX inverter is on your quote?
SolaX splits into two families that solve different problems. Pick by whether a battery is part of the plan.
X-Hybrid series: battery-ready
The X-Hybrid is SolaX's hybrid inverter, built to run solar and a battery from one unit. It comes in single-phase (X1-Hybrid) and three-phase (X3-Hybrid) variants.
| Model | Phase | Solar input | Battery pairing |
|---|---|---|---|
| X1-Hybrid G4 (3.7–7.5kW) | Single | 2 MPPT | SolaX Triple Power T-BAT or compatible third-party |
| X3-Hybrid G4 (5–15kW) | Three-phase | 2 MPPT | SolaX Triple Power T-BAT or compatible third-party |
G4 (Generation 4) is the current line. Earlier G3 units still turn up in quotes from existing installer stock, so it's worth asking which generation you're being sold.
The X-Hybrid pairs natively with SolaX's own Triple Power T-BAT battery: LFP chemistry, 5.8kWh per module (11.6kWh for two), carrying a 10-year warranty. It also works with certain third-party LFP batteries, which widens your storage choice beyond a single locked ecosystem. Confirm the exact battery model with your installer, because compatibility is per-model, not blanket.
X3-MIC string inverters: solar-only
If a battery isn't in the plan, SolaX offers the X3-MIC three-phase string inverters (3–15kW). These are solar-only. Adding a battery later means AC-coupling a separate battery inverter or swapping the inverter outright, so if storage is a "maybe", weigh a hybrid up front. Our string vs hybrid explainer covers that trade-off in detail.
How efficient is a SolaX inverter?
The SolaX X-Hybrid G4 peaks at around 97.6% efficiency. That's the top of its curve; the everyday weighted figure sits a little under, which is normal for any string or hybrid inverter.
Here's how that lands against the two brands SolaX is most often compared to in Perth:
- SolaX X-Hybrid G4: up to around 97.6%
- Sungrow SH: up to around 98.4%, and it varies by model across the SH range
- GoodWe DNS: up to 97.8% (note this is GoodWe's solar-only single-phase string inverter, not a hybrid)
A point of peak efficiency is not the number to buy on. Even a one-point peak-efficiency gap, say 97.6% against Sungrow's 98.4%, is small across a year in Perth next to sizing, shading, and how much of your solar you actually use at home. If you want to know which spec lines genuinely move the needle, read how to read solar inverter specs.
Heat de-rating in a Perth summer
Like most string and hybrid inverters, the X-Hybrid G4 de-rates its continuous output above 45°C ambient. Perth summers hit that regularly, so mounting matters: keep the inverter shaded or on a cool wall, out of direct afternoon sun, so it isn't throttling output on the days you're generating the most. Ask your installer where it's going before they mount it.
What does a SolaX warranty cover, and for how long?
Two products, two warranty terms.
- X-Hybrid inverter: a 5-year standard warranty, freely upgraded to 10 years once the unit is connected to SolaX Cloud and generation data is successfully uploaded. Confirm your installer completes this registration so the extension actually applies. Under Australian Consumer Law, your rights sit on top of any manufacturer warranty regardless.
- Triple Power T-BAT battery: a 10-year warranty, retaining at least 70% of its rated energy over that term.
A 10-year warranty on registration is competitive for the mid-tier field, and it matches the shape most other mid-tier brands use: a 5-year base term with a free extension once you register. Confirm the current terms for any brand on your shortlist with the installer, since terms change.
The New Energy Tech Consumer Code requires a minimum 5-year whole-of-system workmanship warranty from an Approved Seller, which is separate from the inverter's own product warranty. Both should be on your paperwork.
How do you monitor a SolaX inverter?
SolaX runs on two monitoring platforms:
- SolaX Cloud (solaxcloud.com) is SolaX's own platform, reached by app or browser. It shows real-time generation, battery state of charge, and grid export.
- Some SolaX inverters also report to Solarman, a third-party monitoring platform that's popular with Australian installers.
Both give you the live data you need to see whether the system is doing its job. SolaX Cloud is functional but less polished than iSolarCloud (Sungrow) or Solar.web (Fronius). If day-to-day app quality matters to you, it's worth a look at the interface before you commit.
What does a SolaX system cost to install in Perth?
Installed pricing moves with system size, battery capacity, roof complexity, and the installer. Treat the ranges below as an indicative starting point for 2026, not a quote:
| System | Approximate installed price |
|---|---|
| 6.6kW solar + SolaX X1-Hybrid + 11.6kWh T-BAT | $15,000–$20,000 |
| 6.6kW solar + SolaX X3-Hybrid + 11.6kWh T-BAT | $17,000–$22,000 |
| 6.6kW solar + SolaX X3-MIC (no battery) | $7,000–$11,000 |
SolaX usually prices between Sungrow at the lower end and Fronius at the higher end for comparable capacity. The only way to know your number is competing quotes, ideally including at least one Sungrow quote to benchmark against.
How does SolaX compare to Sungrow and GoodWe?
| SolaX X-Hybrid G4 | Sungrow SH (hybrid) | GoodWe (hybrid range) | |
|---|---|---|---|
| Peak efficiency | up to ~97.6% | up to ~98.4%, model-dependent | mid-to-high 97% band |
| Base warranty | 10yr, subject to registration | 5yr, extension available | 5yr, extension available |
| Battery ecosystem | T-BAT LFP plus compatible third-party | SBR (Sungrow only) | own plus compatible third-party |
| Perth installer depth | Growing but limited | Very deep | Moderate |
| Monitoring | SolaX Cloud | iSolarCloud | SEMS Portal |
Where SolaX beats Sungrow: battery choice. The X-Hybrid takes SolaX's own T-BAT or a compatible third-party LFP battery. Sungrow's SH hybrid pairs with the Sungrow SBR, so SolaX's openness gives you more storage options if you want to shop the battery separately.
Where SolaX loses to Sungrow: service depth. Sungrow has a much thicker Perth installer and distributor network. If a SolaX inverter faults, how fast you get it sorted depends heavily on which installer fitted it and where they source SolaX parts. That's the single biggest reason to weigh the installer as hard as the inverter.
One note on the comparison: GoodWe's DNS is a solar-only string inverter, not a hybrid, so a like-for-like battery-ready comparison uses GoodWe's hybrid range instead. For what a hybrid has to do that a string inverter does not, see our Perth hybrid inverter guide.
What should you ask a SolaX installer?
- Is this the G4 (current generation) or an earlier G3 model?
- Will you register the inverter on SolaX Cloud at install so the 10-year warranty extension actually applies?
- Are you quoting the SolaX T-BAT battery, or a third-party battery paired with the X-Hybrid, and is that pairing confirmed compatible?
- How many SolaX systems have you installed in Perth, and who handles a warranty claim if one comes up?
- Where will the inverter be mounted, given its de-rating above 45°C in a Perth summer?
SolaX is a solid mid-tier pick for a Perth home that wants a hybrid inverter with more battery flexibility than a locked ecosystem. The real constraint is installer depth, so get competing quotes, including at least one Sungrow quote, and choose the installer as carefully as the brand. If you're still deciding between hybrid and solar-only, our hybrid inverter guide is the place to settle that first.
