Solar inverter prices in Perth (October 2026)
Supplied and installed as part of a new 5–10kW residential system in Perth, GST inclusive. An inverter is normally 15–25% of the system price (6.6kW in Perth: $4,340–$6,320 after STCs), so the brand you pick moves the total by about $783–$1,371.
Which inverter for a Perth roof?
- Simple, unshaded north roof: a string inverter (Sungrow, GoodWe, Huawei) is the value pick — $1,273–$2,545 installed.
- Fronius or SMA: the premium string inverters — 10-year warranties, strong local support, $1,958–$3,720. Fronius Primo and Symo are the common Perth models.
- Shaded or multi-aspect roofs: Enphase micro-inverters ($2,741–$5,385) or a string inverter with optimisers.
- Battery planned: ask for a hybrid inverter (Sungrow SH, GoodWe ET, Fronius GEN24) so the battery DC-couples later without replacing it.
- Heat: Perth summers derate inverters — mount in shade or a garage, never on a west wall.

Can I get an inverter price list from an installer?
Most Perth installers price the inverter inside the system quote. Ask for it itemised — a quote that lists panel and inverter model numbers and the STC discount separately is one you can compare.
