Two hybrid inverters commonly compared for Perth homes. Fronius is made in Austria, Sungrow in China. The differences below help you weigh each one against your quote.
Quick verdict
Choose Fronius if active cooling for Perth heat, PV Point backup without a battery, and AC or DC battery coupling matter to you, and the 20-30% higher price fits your budget. Choose Sungrow if a lower price, a 10-year standard warranty, and integration with Sungrow's own SBR battery are the priorities.

For many Perth homes, the Sungrow SH paired with an SBR battery is a practical choice: a 10-year standard warranty, a lower price than the Fronius, and an Australian support office. It is the inverter most local installers quote.
Consider the Fronius GEN24 Plus if your budget allows and you want its active cooling for hot, exposed installations, PV Point solar backup, or AC and DC battery coupling.
Both inverters meet WA requirements: Synergy SSL listing, ESM compliance, and export limiting. Both are installed by Perth installers.
