Premium Inverters That Maximise Every Sunny Day

Austrian-engineered, family-owned, the gold standard for Australian roofs.

Fronius has been building inverters in Austria for 30+ years and is widely regarded as the most reliable and longest-lived inverter brand in the Australian market. Active cooling keeps the unit running flat-out even on 40°C+ Victorian rooftops, the Solar.web monitoring platform is the most detailed in the industry, and Fronius products are designed to be repaired — not thrown away — with a strong network of factory-trained Australian technicians. The GEN24 hybrid range now adds battery-ready functionality to the same legendary build quality.

Microinverters — one per panel, total redundancy, 25-year warranty.

Enphase pioneered microinverter technology and remains the global leader. Instead of one large string inverter, every panel gets its own tiny microinverter mounted underneath — so shading, soiling or a fault on one panel never drags the whole system down. Combined with per-panel monitoring, no high-voltage DC on the roof and the longest warranty in the industry, Enphase is the premium choice for complex roofs, multiple orientations or homeowners who want the absolute best.

Fully AI-powered all-in-one energy controller.

Sigenergy's SigenStor is a next-generation modular energy controller (hybrid inverter) that combines PV inverter, battery management, EV-DC charging and AI-driven energy optimisation in one slim, stackable cabinet. Up to 200% PV oversizing on single-phase units, full grid + off-grid capability, and the mySigen AI engine that learns your home's usage to maximise self-consumption and savings automatically.

World's most-deployed inverter brand — and Victoria's quiet favourite.

Sungrow is the world's largest inverter manufacturer with 28+ years of pure inverter focus and over 605 GW deployed globally. Their SG single-phase, SG three-phase and SH hybrid ranges have become the everyday workhorse of Australian rooftops thanks to outstanding reliability, excellent value, an integrated battery ecosystem (Sungrow SBR) and one of the best warranty service records in the country. Premium models include built-in arc-fault detection, IP66 weather-rating and a powerful, polished iSolarCloud monitoring app.

DC-optimised inverters — every panel optimised, every panel monitored.

SolarEdge takes a unique approach: a small DC optimiser sits behind every panel, mitigating shading and mismatch losses, and feeds a single high-efficiency string inverter on the wall. The result is the per-panel intelligence of microinverters with the simplicity of a string inverter — and the longest module-level warranty on the market (25 years on the optimiser). The Energy Hub hybrid range adds battery-ready functionality. SolarEdge is the premium choice for shaded or complex roofs that don't justify a full microinverter system.

Award-winning hybrid inverters with the best app in the business.

GoodWe is one of the fastest-growing inverter brands in Australia and a multi-time Intersolar award winner. Their MS single-phase, SDT three-phase and ET/EH hybrid ranges have become a Victorian favourite thanks to a flexible battery-agnostic hybrid design, an excellent SEMS Portal monitoring app and strong local Australian support out of Sydney. The hybrid range is widely regarded as the most flexible battery-ready inverter on the market — pair it with a GoodWe Lynx Home battery or with most third-party batteries.

Pure-play inverter specialist with 20+ years of focus.

Solis (Ginlong Solis) is one of the world's oldest pure-play string inverter manufacturers — listed on the Shenzhen exchange, with 20+ years of single-minded focus on inverter design. The 5G series became a Victorian favourite thanks to clean reliability, multi-MPPT designs that suit complex roofs, built-in WiFi monitoring and DC injection protection, and excellent value. Standard 5-year warranty extends to 10 years through Sunline.

Sleek single-phase string inverters — a clean, value-led choice.

Solax is a global top-10 hybrid inverter manufacturer with a strong residential single-phase line-up. The X1 Boost G4 series delivers a clean, compact design with built-in WiFi, dual-MPPT input, IP66 weather-rating and one of the smallest footprints in its class — well-suited to garage and outdoor wall installs. Reliable, easy to live with and well-supported in Australia.

Global top-5 inverter brand — outstanding value with hybrid options.

Growatt is one of the world's top-5 residential inverter brands by volume, with millions of units installed in over 100 countries. The MIN single-phase, MOD three-phase and XH hybrid ranges deliver tier-1 build quality at a value-led price point. Multi-MPPT designs handle split-roof homes well, and the ShinePhone monitoring app is genuinely good. A solid choice when budget matters but corner-cutting is not an option.

Established string inverter specialist — strong value with R5 series.

SAJ has been making inverters since 2004 and is one of China's longest-running power-electronics specialists. The R5 series is a clean, no-nonsense string inverter range that's earned a quiet but loyal Victorian following thanks to reliable performance, built-in WiFi monitoring, and great value at the entry-tier-1 price point. A solid pick when budget is the priority but warranty support still matters.
