Welcome to the Kimberley frontier,
Where the sun don’t quit, the red dust bites, and the grid’s more tumbleweed than town hall. Out here, your solar inverters ain’t just a piece of gear — it’s your sheriff, your saloon keeper, and your last line of defence when the power cuts out.

So we rounded up the 6 toughest-looking brands allowed on Horizon Power’s Smart Connect scheme:
Fronius, SMA, Sungrow, Solax, GoodWe, and Growatt.

They all wear the badge — certified under AS4777.2:2020 — but when it comes to surviving Broome’s brutal conditions, only a few are up to the job.

So let’s take a good, hard look at who’s ready to ride… and who should turn back at the edge of town.

Fronius – The Marshal

Origin: Austria
Profile: A seasoned lawman with real backbone. Knows the territory and doesn’t flinch under pressure.

Fronius inverters are engineered for warzones like Broome. With robust Austrian construction and active cooling, they stand tall in 40+ degree heat without breaking a sweat. Their GEN24 Plus series offers full hybrid functionality — so when the grid carks it, your power doesn’t.

Verdict:
Fronius is the local sheriff we trust — reliable, intelligent, and made to handle a shootout with the Kimberley sun. Our top pick.

SMA – The German Deputy

Origin: Germany
Profile: Clean, calculated, and by the book. Quiet type, but always shows up.

SMA’s Tripower inverters are a solid choice for grid-tied systems. Built with durability in mind and featuring active cooling in key models, they don’t crack under pressure. Hybrid options exist but aren’t yet Horizon Power-approved.

Verdict:
Dependable and professional. Not quite the full hybrid package, but if you’re staying grid-connected, this is a deputy worth riding with.

Solax – The Ranch Hand That Needs Shade

Origin: China
Profile: Keen to work and easy to set up, but wilts under pressure. Packs a lunchbox inverter for a cattle station job.

Solax offers clean-looking hybrid systems at competitive prices — and their X-Hybrid series ticks a lot of boxes on paper. But in practice, passive cooling and tight tolerances mean Solax units can struggle in Broome’s climate, especially during sustained high-output periods.

Monitoring via Solax Cloud is basic but functional. The hybrid models do offer backup capabilities — however, this often needs careful design and is typically only partial-load.

Verdict:
Solax might do alright in a shaded carport in Perth, but it’s underpowered for the Kimberley. We don’t recommend it for mission-critical or off-grid setups — it just isn’t cowboy enough for the wild north.

Sungrow – The Quickdraw That Overheats

Origin: China
Profile: Fast on paper, flashy in town, but drops the gun in a heatwave.

Sungrow’s lab results are impressive, and pricing is sharp. But in the field? Passive cooling lets it down in Broome’s climate. We’ve seen units throttle or shut down right when they’re needed most.

Verdict:
Good specs, but overheats in the thick of it. Not a brand we saddle up with north of the Tropic.

GoodWe – The Hybrid Hustler

Origin: China
Profile: All talk, no trousers. Promises backup, folds in the midday sun.

GoodWe’s hybrid marketing is loud, but we’ve seen too many faults in Broome to believe the hype. Systems derate under heat, SEMS monitoring is clunky, and backup capability is often limited.

Verdict:
The snake oil salesman of the solar game. We steer clear.

Growatt – The Budget Bandit

Origin: China
Profile: Rides in cheap, rides out broken. Looks the part, but lacks the grit.

Lightweight components, passive cooling, and shaky reliability make Growatt solar inverter a poor match for the Kimberley. Their hybrid features are minimal, and support can be hit-and-miss.

Verdict:
Might save you upfront coin, but expect a short ride before breakdown. Not fit for the Broome frontier.

Bottom Line: We Don’t Use These Around Here

Broome ain’t the ‘burbs. It’s remote, it’s ruthless, and it doesn’t forgive weak systems.
We only install solar inverters we’d trust on our own homes.

Fronius is our go-to — the undisputed lawman of the solar inverter world.
SMA is a strong second for grid setups.
The rest? Might talk tough, but we’ve seen too many of ‘em break when the heat’s on.
