The 2026 ranking
Five inverter brands we'd actually quote on a customer's home in 2026, ranked by long-term value — not just sticker price.
Sungrow SG / SH series
The #1 installed inverter in Australia for a reason. Sungrow nailed the price/performance/reliability triangle. SG-RS string range for grid-tie, SH-RT hybrid range pairs natively with SBH batteries. Service network is the deepest of any Chinese brand and AU-staffed.
- Best value tier-1
- Pairs with Sungrow SBH battery natively
- Excellent iSolarCloud app
- Largest AU installed base
- Not made in EU/US
- Backup needs extra Sungrow Backup Box
Fronius Primo GEN24 / Symo GEN24 Plus
Austrian-engineered, the gold standard for build quality and serviceability. GEN24 Plus models add hybrid + battery backup capability. Costs 30–50% more than Sungrow but the longest-living inverter brand we install — 15+ year field reliability proven.
- Austrian build quality
- PV Point emergency power (no battery needed)
- Field-serviceable parts
- Best long-term reliability
- 30–50% price premium
- App lags Sungrow/Enphase
Enphase IQ8P / IQ8M microinverters
One inverter per panel = zero shading penalty, panel-level monitoring, and a 25-year warranty matching the panels. Best choice for complex roofs (multiple aspects, partial shade, dormers). IQ Battery 5P pairs natively. Most expensive option per kW.
- 25-yr warranty
- Per-panel monitoring
- Zero shading loss
- Easy to expand later
- Highest $/kW
- Many devices on the roof
- Sunlight Backup needs IQ Battery
SolarEdge Home Hub / Genesis
Power optimisers on every panel give per-panel monitoring and shading mitigation, with a single central inverter handling DC-DC and grid. Best for big systems with split shade. SolarEdge's 2022–24 reliability dip has improved with Genesis-gen hardware, but historic RMA volume remains a watch-item.
- Per-panel monitoring at lower cost than Enphase
- Excellent for complex shaded roofs
- Strong hybrid + battery integration
- Historical RMA volume above peers
- More single points of failure than Enphase
- Older firmware bugs lingering
GoodWe ES / ET / EH series
The most aggressive value play in 2026. Genuine tier-1 manufacturer, listed on Shenzhen exchange, decent SEMS Portal app. Pairs with GoodWe Lynx battery. Where Sungrow leads on service depth, GoodWe leads on sticker price. Fine for cost-driven self-consumption builds.
- Cheapest tier-1 hybrid
- Strong global volume = stable parts supply
- 10-yr standard warranty
- Smaller AU service network than Sungrow/Fronius
- App lags top three
- Brand recognition lower
Six factors that decide your pick
More important than brand loyalty — these are the technical specs that determine whether an inverter is right for your roof and household.
String vs micro vs optimisers
String (Sungrow, Fronius, GoodWe) is the right call for simple north-facing roofs — cheapest and most efficient. Microinverters (Enphase) are the right call for split-aspect or partly shaded roofs. Optimisers (SolarEdge) sit in between.
Hybrid vs grid-tie
Hybrid inverters (Sungrow SH, Fronius GEN24, GoodWe ET, SolarEdge Hub) cost $400–$1,000 more upfront but let you add a battery later without rewiring. If you'd ever consider a battery, get a hybrid now.
Warranty: length AND service
10-year warranty is standard; Enphase offers 25. But the warranty is only as good as the service network. Sungrow, Fronius and Enphase have full AU offices. SolarEdge service times have lengthened. GoodWe is improving but still trails.
Monitoring app matters daily
You'll use the app every week for 10+ years. Best: Enphase Enlighten and Sungrow iSolarCloud (per-panel/per-string detail, fast). Good: SolarEdge Monitoring, Fronius Solar.web. OK: GoodWe SEMS Portal (clunky but works).
Battery compatibility
Sungrow SH → Sungrow SBH. Fronius GEN24 Plus → BYD HVS. SolarEdge Hub → SolarEdge Home Battery. Enphase IQ8 → IQ Battery 5P. GoodWe ET/EH → GoodWe Lynx or BYD. Mismatched pairings work but lose features (no panel-level optimisation, no native backup).
Single-phase vs three-phase
Standard homes use single-phase up to 5kW inverter. Larger homes (10kW+ system, ducted A/C, EV charging, pool) should use three-phase — better balance across the switchboard and higher export limits in Energex zones.
Inverters we won't quote
No-name string inverters under $700 supply price, brands without an AU-based service office, inverters where the warranty is fronted by the installer rather than the manufacturer, and any unit not on the Clean Energy Council Approved Inverter List. If a quote is using a brand you've never heard of, ask why.
