GoodWe vs SolaX inverter Perth: which mid-tier Chinese hybrid is right for your home?

After Sungrow, GoodWe and SolaX are Perth's most commonly quoted mid-tier hybrid inverter options. Both are Chinese manufacturers with Australian distribution, similar price positioning, and comparable specifications. Here's what separates them.

Products being compared

GoodWe DNS hybrid: GoodWe's residential hybrid inverter range (DNS-D G3 for single-phase, GW-DNS for earlier model references). Available from 3–10kW single-phase. The DNS-D G3 is the current residential product.

SolaX X-Hybrid G4: SolaX's current hybrid inverter (X1-Hybrid G4 for single-phase, X3-Hybrid G4 for three-phase). Available from 3.7–15kW.

Specification comparison

| Spec | GoodWe DNS-D G3 (5kW) | SolaX X1-Hybrid G4 (5kW) | |---|---|---| | Max output | 5kW | 5kW | | MPPT channels | 2 | 2 | | Peak efficiency | 97.6% | 97.8% | | Warranty (base) | 5 years | 5 years | | Warranty (extended) | 10 years (via registration) | 10 years (via registration) | | Battery compatibility | GoodWe Lynx Home + third-party | SolaX T-BAT + third-party | | Monitoring | SEMS Portal | SolaX Cloud / SolarmanBMS | | Three-phase option | GW-ES (separate range) | X3-Hybrid G4 |

Where they differ

Battery compatibility

Both GoodWe and SolaX offer more battery flexibility than Sungrow SH (which requires Sungrow SBR only):

GoodWe DNS-D G3: Officially pairs with GoodWe Lynx Home battery (LFP, 5.84kWh modules). Also has compatibility mode for third-party LFP batteries (BYD, Pylon, Alpha ESS). Battery compatibility depends on firmware version — verify with your installer.

SolaX X-Hybrid G4: Officially pairs with SolaX T-BAT (LFP, 5.8kWh or 11.6kWh). Also has third-party battery compatibility (broader than GoodWe according to SolaX documentation) — Pylon, Dyness, Solax-compatible BMS batteries.

Advantage: SolaX claims broader third-party battery compatibility than GoodWe. Both are more flexible than Sungrow's locked SBR-only ecosystem. Verify specific battery pairing compatibility with your installer for both.

Monitoring

GoodWe SEMS Portal: Web-based monitoring at semsportal.com. Shows system generation, battery state, consumption, and export. Mobile app available. Functional but less polished than Sungrow's iSolarCloud.

SolaX Cloud: SolaX's own platform. Some installers configure SolaX inverters to report to SolarmanBMS instead — a third-party platform popular with Australian solar businesses for multi-brand fleet management. Either monitoring option is functional.

Perth installer depth

GoodWe has a slightly larger Perth installer base than SolaX — GoodWe entered the Australian market earlier (circa 2014) and has more Australian installer training records. For post-installation service, a larger local installer base is an advantage.

SolaX is growing in Perth but has a thinner established installer network. The quality of SolaX installation depends heavily on individual installer SolaX experience.

Three-phase product

SolaX X3-Hybrid G4 (three-phase) is a single integrated product at 5–15kW. Perth homes with three-phase supply wanting SolaX need one X3-Hybrid G4 unit.

GoodWe offers the GW-ES series (three-phase) for higher-power three-phase applications. For standard Perth three-phase residential (10–15kW), both are available.

Perth pricing

For a 6.6kW solar-only system with single-phase hybrid inverter:

| System | Approximate Perth installed price | |---|---| | 6.6kW + GoodWe DNS-D G3 (5kW) | $7,500–$11,000 | | 6.6kW + SolaX X1-Hybrid G4 (5kW) | $7,500–$11,500 | | 6.6kW + Sungrow SH5RS | $7,000–$10,500 |

GoodWe and SolaX are broadly comparable in price, both slightly above Sungrow.

Which to choose

Choose GoodWe when:

• Your installer has more GoodWe experience and service relationships
• GoodWe Lynx Home battery is the storage option (or compatible third-party)
• Installer depth matters for your post-installation confidence

Choose SolaX when:

• Your installer has strong SolaX experience
• You want the broadest third-party battery flexibility
• Three-phase is needed (X3-Hybrid G4 is a strong three-phase option)

Consider Sungrow SH instead when:

• Price per kWh is the primary driver (Sungrow typically wins on value)
• Deepest Perth installer network and service depth is a priority
• Sungrow SBR battery is the storage plan (locked ecosystem is acceptable)

GoodWe and SolaX are closely matched mid-tier alternatives to Sungrow for Perth hybrid installations. The GoodWe advantage is a slightly deeper Perth installer base; the SolaX advantage is broader third-party battery compatibility. For most Perth buyers comparing these two, the installer's experience with the specific brand matters more than the brand itself — get at least one Sungrow quote as a price benchmark before committing to either.
