The quiet box doing all the work.

The inverter converts what your roof makes into power your home can use — and it’s the component that decides whether your system can take a battery later.

Panels get the attention; the inverter earns it. We’ll spec yours for where your system is going, not just where it starts.

GoodWe

The value pick — 5 kW to 15 kW

Compact single- and three-phase units with strong app monitoring out of the box. Suits straightforward roofs and budgets that still want a hybrid-ready path. Exact model and warranty terms are stated on your quote.

ACT · TASEnquire

Solax

The battery-first choice — 5 kW to 20 kW

Built around storage from day one — the X-Hybrid range pairs with Solax batteries for backup power. Our pick when solar and battery land together. Exact model and warranty terms are stated on your quote.

The honest bit: if a battery is in your future, the inverter choice today matters more than the panel brand — a hybrid inverter now can save a replacement later. If you’re never adding storage, don’t pay for one.

What to Consider When Choosing an Inverter:

INVERTER TYPE: GRID-TIED VS. HYBRID

Decide between a grid-tied inverter (ideal for systems connected to the mains) or a hybrid inverter if you want to add battery storage now or later.

PERFORMANCE & MONITORING

Look for a high-efficiency inverter (95%+), with smart monitoring features so you can easily track your system’s performance in real time.

BATTERY COMPATIBILITY

If you’re considering energy storage, choose a hybrid inverter that works seamlessly with leading battery systems — now or down the track.

WARRANTY & BRAND SUPPORT

Stick with reliable brands that offer strong warranties and Australian-based support. Astra Solar only installs trusted inverters from Sungrow, GoodWe, and Solax.

What Is a Solar Inverter?

A solar inverter converts the DC (direct current) electricity produced by your solar panels into AC (alternating current) electricity that your home or appliances can use. Without it, your solar system can’t power anything.

There are different types of inverters to suit different energy goals—like storing power in batteries, optimising solar performance across shaded roofs, or just keeping things simple with a grid-tied setup.

Solar Inverters FAQs

A grid-tied inverter converts your solar power for use in your home and exports any excess to the grid. A hybrid inverter does the same but can also charge and manage a battery, so it’s the right choice if you have — or plan to add — battery storage.

It depends on your system size, roof and goals. We quote from our approved range — Jinko, LONGi, Sungrow, GoodWe and Solax — and match the inverter to your panels and any battery plans rather than pushing one brand.

Yes. Every inverter we install comes with a manufacturer monitoring app so you can see generation, consumption and system status from your phone.

Quality inverters typically run for 10–15 years, with manufacturer warranties commonly 5–10 years depending on the brand and model. We’ll confirm the exact warranty for your quoted inverter.

Yes — your inverter keeps working whenever the panels generate, just at reduced output in low light. For shaded roofs we design around it with panel layout and, where appropriate, optimisers.

No — modern inverters produce only a faint hum. We install them in a suitable location (garage or shaded wall) following the manufacturer’s guidelines.
