What a Sungrow inverter costs in October 2026
The one public anchor for a Sungrow price is the list price on an Australian electrical supply site, read 27 October 2026: ex GST as published, with GST added in the next column, supply only. Installers buy below list and sell above it, so the inverter line on a quote should sit close to these figures plus margin, with a model number beside it.
| Model | Type | Phase | AC rating | Ex GST | Inc GST | $ per W (ex) | List |
|---|---|---|---|---|---|---|---|
| SG5.0RS | String | Single | 5 kW | $1,090 | $1,199 | $0.22 | Sparky Direct |
The SG5.0RS at $1,199 inc GST is $1,489 below a Fronius Primo GEN24 5.0 at list, with a ten-year warranty against five (ten on registration). No public list price was found for the SG10RT three-phase or the SH5.0RS hybrid; SolarQuotes quotes a Sungrow 5 kW hybrid at $2,300 and a 10 kW three-phase hybrid at $4,500 after rebate in its battery cost guide (12 May 2026).

Sungrow inverter warranty
10 years as standard. Ten years from installation but no more than eleven from manufacture, Australia only; SG RS, SG RT, SH RS and SH RT all listed. Read from Sungrow Australia Group 10-Year Standard Warranty Terms V4.2, April 2024; linked in the sources below. A string inverter is the part of a solar system most likely to be replaced inside the panels' 25-year warranty, so the registered term and who services it locally matter more than the sticker price; the inverter replacement page prices the swap.
Where a Sungrow fits
The cheapest mainstream unit on a public Australian list with a ten-year warranty as standard; the SH hybrid is the only inverter the Sungrow SBR battery connects to, so a Sungrow battery decision is an inverter decision.
Two storeys, a tile roof, three phase and an old switchboard add the same sourced lines to a quote whatever the inverter brand; those ranges are on the what affects the price page, and the quote check reads a whole quote against the index.
