GoodWe and SolaX are two Chinese-made hybrid inverters with Australian distribution that sit in the same value bracket on Perth quotes. On the headline numbers they are close: similar peak efficiency, two MPPT channels on the common single-phase sizes, and a standard warranty that commonly extends to 10 years on registration. Here is a fair, spec-led comparison, and the practical points that separate them.
Quick answer
Installer familiarity decides this one more often than the spec sheet does. Pick GoodWe if you want the more widely-installed of the two in Perth and a broad local service base. Pick SolaX if the battery you want is on SolaX's approved pairing list and your installer has real SolaX experience. Inverters aren't separately rebated in WA; battery-rebate eligibility is decided at system level by the battery's Synergy SSL listing.
