All inverters reviews
Enphase
IQ8
Enphase
Enphase IQ8
The IQ8 is the strongest choice for shaded, multi-orientation or awkward roofs, with low-voltage DC on the roof and a 25-year microinverter warranty. You pay a clear premium over a good string inverter, and the warranty covers parts only, so on a simple sunny roof the extra money buys less than the brochure suggests.
Best for: Shaded or split roofs where panel-level output and low-voltage DC matter
InverterFronius
Fronius Primo
The Primo GEN24 is a well-supported, quiet single-phase string inverter with a strong Australian service record and a cheap path to adding a battery later. You pay a clear premium over Sungrow for that, and the free 10-year warranty depends on registration and promotion terms you should confirm in writing.
Best for: Single-phase homes wanting a premium European string inverter with an upgrade path to a battery
Fronius
GEN24 Plus
Fronius
Fronius GEN24 Plus
The GEN24 Plus is a well-built, well-supported hybrid that suits owners who value Fronius service and want three-phase backup or a Fronius-branded battery. Its backup is not seamless, its battery list is short and it costs more than a Sungrow hybrid, so it only makes sense if those trade-offs do not bother you.
Best for: Homes adding a battery now that want premium local support and optional whole-home or three-phase backup
InverterGoodWe
GoodWe DNS, EH and ET
GoodWe's DNS string inverters are a sound budget pick with a local office and a 10-year warranty once registered online, and the ET G2 is a capable three-phase hybrid. Read the warranty conditions closely, though: several hybrids only get 10 years if paired with a GoodWe battery, and owners in hot climates report noticeable summer derating.
Best for: Budget to mid-range single-phase systems and three-phase homes wanting a hybrid
InverterHuawei
Huawei SUN2000
The SUN2000 L1 and M1 were well-liked, efficient hybrid-ready inverters, and owners still rate them highly. But Huawei stopped selling them in Australia in early 2024 and no Huawei inverter is on the Clean Energy Council approved list, so do not accept one on a new quote; if you already own one, plan around the end-2026 battery expansion cut-off.
Best for: Existing owners checking warranty, support and battery expansion options
SMA
Sunny Boy
SMA
SMA Sunny Boy
The Sunny Boy AV-41 is a quiet, fan-less string inverter with a long reliability record, but SMA withdrew from Australian home solar sales in 2026. Only buy one as clearly discounted remaining stock with the warranty terms in writing; for a new system, a Fronius or Sungrow inverter is the safer choice.
Best for: Like-for-like replacement of a failed Sunny Boy, or buyers offered heavily discounted remaining stock
SolarEdge
Home Hub
SolarEdge
SolarEdge Home Hub
SolarEdge gives you panel-level optimisation and monitoring for less than a full microinverter system, plus a clean upgrade path to a DC-coupled SolarEdge battery and backup. The trade-off is a single wall inverter that owners in hot climates report failing more often than they would like, and a support record that only improved after 2023.
Best for: Shaded or multi-face roofs where you want panel monitoring and a SolarEdge battery later
Solis
S6 series
Solis
Solis S6 series
Solis makes a solid budget string inverter with a local office in Melbourne and a 10-year warranty once registered on SolisCloud, and its 48 V hybrids work with many battery brands. The catches are a warranty that drops to 5 years if the inverter goes offline, labour and freight you may pay yourself, and owner ratings a notch below GoodWe's.
Best for: Budget single-phase systems, and hybrids paired with a third-party 48 V battery
Sungrow
SG RS
Sungrow
Sungrow SG RS
The Sungrow SG RS is the value benchmark for single-phase string inverters, with generous tracker current, fan-less cooling and a 10-year standard warranty at a price well below Fronius. The trade-off is a more uneven support experience, a one-year warranty on the Wi-Fi dongle and meter, and no battery port.
Best for: Single-phase homes wanting a capable, well-warranted solar-only inverter at a mid-market price
Sungrow
SH RS / RT hybrid
Sungrow
Sungrow SH RS / RT hybrid
The Sungrow SH RS is the value pick for a single-phase solar and battery system, with near-instant backup, high solar oversizing and broad VPP support at well below Fronius prices. Check which model you are quoted, because only the SH8.0RS and SH10RS offer whole-home backup, and accept that you are tied to Sungrow batteries.
Best for: Homes adding a Sungrow battery now that want fast backup and VPP options at a mid-market price
