The brains of your solar system. Sigenergy & GoodWe, sized and installed properly.

Your panels generate the power, but the inverter decides how much of it you actually get to use. We specify Sigenergy and GoodWe inverters, matched to your system, with app-based monitoring and a genuine manufacturer warranty.

Why the inverter matters

Panels get the attention. The inverter does the harder job.

Solar panels generate DC electricity, but your home runs on AC. The inverter’s job is to convert that power safely and efficiently, and it’s also what determines how much of your system’s potential output you actually get to use, how it’s monitored, and how it behaves if something goes wrong.

A premium panel paired with a poorly specified inverter is a system that underperforms quietly for years. We design the inverter into your system from the start, sized to your specific panel array, not picked off a shelf to hit a price point.

We specify Sigenergy and GoodWe, two manufacturers with a genuine track record in Australian conditions, real local warranty support, and monitoring apps that are actually worth using.

Make sure your system's inverter is right

Inverter playing up, or just want it checked? Call us.

We’ll talk through your system over the phone and tell you honestly whether it’s sized and set up the way it should be.

Brand comparison

Sigenergy, GoodWe, Fronius, or Sungrow: which suits your system?

Both are reputable manufacturers we’re happy to install. We’ll recommend one based on your system size, budget, and what matters most to you.

Sigenergy

An AI-powered energy systems manufacturer built for smart monitoring and performance. We're a Sigenergy Gold Installer, a status recognised directly by the manufacturer.

GoodWe

A global manufacturer with a large international footprint and a strong range of grid and battery-ready inverter models, often a good fit when you're planning to add storage later.

Fronius

An Austrian manufacturer with decades of testing behind its inverters, well regarded for reliability and build quality. A strong default choice when long-term dependability is the priority.

Sungrow

Established in 1997, Sungrow is one of the longest-running names in solar inverter R&D, backed by one of the largest dedicated research teams in the industry.

Why it's not interchangeable

Every solar system needs an inverter. Not every inverter is equal.

Unlike a battery or a diverter, an inverter isn’t optional. Every solar system has one. The difference is in how good it is, and how long it lasts.

A weak inverter limits a good system

Even premium panels are bottlenecked by a poorly specified inverter. The inverter has to match the array, not just be cheap enough to install.

It's often the first thing to fail

Inverters typically have a shorter lifespan than panels. A genuine manufacturer warranty matters more here than almost anywhere else in your system.

It's your window into the system

The inverter's monitoring is how you'll actually see your solar working day to day, a clunky app makes a good system feel invisible.

What you're getting

What separates a properly specified inverter from a generic one.

Every inverter on a spec sheet claims good numbers. Here’s what actually matters once it’s on your wall.

DC to AC conversion, done efficiently

Every watt lost in conversion is a watt you paid for and didn't get to use. Fronius and GoodWe are specified for genuinely high conversion efficiency, not just a headline number.

5–10 year manufacturer warranty

A genuine warranty from a manufacturer with real local support, not a vague promise from an importer who may not exist when you need to claim it.

App-based monitoring

Watch your system's generation, performance, and any fault alerts from your phone, with full monitoring set up and explained before our team leaves.

Built for outdoor conditions

Mounted to handle Adelaide's heat and weather, in a position that balances easy access for servicing with proper protection.

Grid & battery-ready models available

If you're planning to add a battery later, we can specify a model that's ready for it now, rather than needing to be swapped out down the track.

SAA accredited installation

Installed and commissioned by our own licensed, SAA accredited team, no subcontractors, same standard we hold for every product we install.

How It Works

The inverter is designed in
from the first conversation,
not bolted on later.

1

Free quote & system design

We size your panels, inverter, and any battery together as one system, based on your roof and usage, not specced separately and hoped to work well together.

2

Brand & model selection

We recommend Sigenergy, GoodWe, Fronius, or Sungrow based on your system size and goals, including whether you want a battery-ready model for later.

3

Professional installation

Our in-house, SAA accredited team installs and commissions the inverter as part of your system, with monitoring set up before they leave.

4

Warranty & ongoing support

Your inverter warranty is registered and on file with us. If anything ever needs attention, you call the same local number and talk to the same team.

Why Bright Earth Solar

We name the brand on every quote. Most installers don't.

Plenty of quotes just say “inverter” without naming a brand. That’s often how a cheaper, unsupported import ends up on your wall. We specify Fronius and GoodWe by name, install them in-house, and stand behind both the product and our own workmanship.

Complete your system

An inverter is one part of the system. Here's the rest.

We design panels, inverters, and batteries as one system, not bought piecemeal.

AIKO & Risen Solar Panels

The inverter converts what your panels generate, so the panel choice matters just as much. We size both together for the best result.

Sigenergy, AlphaESS & GoodWe Batteries

Planning to add a battery later? We can specify a battery-ready inverter now so you don’t need to swap it out down the track.

Common questions

Everything you wanted to know about solar inverters.

What does a solar inverter actually do?

It converts the raw DC electricity your panels generate into the AC electricity your home actually uses, and it's responsible for the quality, safety, and monitoring of that power. It's often called the brains of the system.

What warranty comes with the inverter?

Fronius and GoodWe inverters carry a 5 to 10 year manufacturer warranty depending on the model. We also stand behind our own installation workmanship.

Are solar inverters durable enough to be mounted outside?

Yes. Fronius and GoodWe inverters are built to handle outdoor conditions, including Adelaide's heat, and are mounted in a position that balances accessibility with weather protection.

Can you replace just my existing inverter without a full system?

It depends on your setup. Inverters are tied closely to your system's design, warranty, and compatibility, so we assess this case by case rather than advertise it as a standalone, off-the-shelf service. Call us to talk through your specific situation.

Why does Bright Earth Solar specify Fronius and GoodWe?

Both are established manufacturers with a strong track record for reliability in Australian conditions, genuine manufacturer warranties, and monitoring apps that are actually good to use day to day.

Can I monitor my inverter from my phone?

Yes. Every inverter we install comes with app-based monitoring set up and explained on the day, so you can see generation, usage, and performance in real time.

How is my inverter sized?

We size and match the inverter to your specific panel array and household usage as part of designing your solar system, not as a generic, one-size-fits-all component.

Do you install inverter brands other than Fronius and GoodWe?

Fronius and GoodWe are the two brands we specify for new systems, chosen for reliability and genuine local warranty support. We're also experienced with SolarEdge and Sungrow if your project calls for one of those, just ask us about your situation.
