SolaX inverter Perth guide: X-Hybrid and string range for WA homes
SolaX is a Chinese inverter manufacturer with a growing Perth presence in the mid-range market. This guide covers the SolaX X-Hybrid series (for battery-ready systems) and X3-MIC string inverters, including performance, warranty, monitoring, and how they compare to Sungrow and GoodWe.

SolaX Power is a Chinese inverter manufacturer founded in 2013 and headquartered in Ningbo. Their products are distributed in Australia through a network of solar distributors and appear in Perth quotes as an alternative to Sungrow, GoodWe, and Growatt in the mid-tier segment. Here's what Perth buyers should know.
SolaX product ranges relevant to Perth
X-Hybrid series (hybrid inverter)
The SolaX X-Hybrid is their battery-ready hybrid inverter, available in single-phase (X1-Hybrid) and three-phase (X3-Hybrid) variants. Key specs for common Perth sizes:
| Model | Single/Three phase | Solar input (MPPT) | Battery compatibility | |---|---|---|---| | X1-Hybrid G4 (3.7–7.5kW) | Single | 2 MPPT | SolaX Triple Power T-BAT / third-party | | X3-Hybrid G4 (5–15kW) | Three-phase | 2 MPPT | SolaX Triple Power T-BAT / third-party |
The X-Hybrid G4 (Generation 4) is the current product line. Earlier G3 models may still appear in quotes from existing installer inventory.
Battery compatibility: The X-Hybrid pairs natively with SolaX's own Triple Power T-BAT battery (LFP, 5.8kWh or 11.6kWh). It also has compatibility with certain third-party LFP batteries (verify with your installer), giving more storage options than a locked ecosystem.
X3-MIC string inverter
For solar-only (no battery) installations, SolaX offers the X3-MIC single-phase and three-phase string inverters (3–15kW). These are non-hybrid — suitable when battery is not planned at installation, with the understanding that adding battery later would require AC coupling or an inverter upgrade.
Performance specifications
SolaX X-Hybrid G4 inverter peak efficiency: 97.8% (comparable to Sungrow SH at 98.3% and GoodWe DNS at 97.6%).
Temperature de-rating: standard for Chinese string/hybrid inverters. The X-Hybrid G4 has a continuous output power de-rating above 45°C ambient — in Perth summers, ensure the inverter is shaded or wall-mounted to minimise thermal de-rating.
SolaX monitoring: SolarmanBMS and SolaX Cloud
SolaX uses two monitoring platforms:
- SolaX Cloud (solaxcloud.com) — SolaX's own platform, accessed via app or browser
- Some SolaX inverters also support SolarmanBMS, a third-party monitoring platform popular with Australian solar installers
Both provide real-time generation, battery state, and export data. SolaX Cloud is functional but less mature than iSolarCloud (Sungrow) or Solar.web (Fronius).
Warranty
- X-Hybrid inverter: 5-year standard warranty (extendable to 10 years via registration on SolaX Cloud within 30 days of installation — typically free)
- Triple Power T-BAT battery: 10-year warranty
The 5-year base warranty is shorter than Sungrow SH (5 years) and GoodWe (5 years + 5yr extension available), comparable to industry standard. Extension registration is important — confirm your installer registers the inverter within 30 days.
Perth pricing
Approximate 2026 Perth installed pricing:
| System | Approximate price | |---|---| | 6.6kW solar + SolaX X1-Hybrid + 11.6kWh T-BAT | $15,000–$20,000 | | 6.6kW solar + SolaX X3-Hybrid + 11.6kWh T-BAT | $17,000–$22,000 | | 6.6kW solar + SolaX X3-MIC (no battery) | $7,000–$11,000 |
SolaX systems are typically priced between Sungrow (lower) and Fronius (higher) for comparable capacity.
How SolaX compares in Perth
| | SolaX X-Hybrid G4 | Sungrow SH (hybrid) | GoodWe DNS (hybrid) | |---|---|---|---| | Peak efficiency | 97.8% | 98.3% | 97.6% | | Warranty | 5yr (ext. to 10yr) | 5yr (ext. available) | 5yr (ext. to 10yr) | | Battery ecosystem | T-BAT LFP + third-party | SBR (own only) | Lynx LFP + third-party | | Perth installer depth | Growing but limited | Very deep | Moderate | | Monitoring | SolaX Cloud | iSolarCloud | SEMS Portal |
SolaX's advantage over Sungrow: third-party battery compatibility gives more storage options. Sungrow SH requires the Sungrow SBR — SolaX's openness allows more battery choice.
SolaX's disadvantage vs Sungrow: thinner Perth service network. If a fault develops, your ability to get timely service depends heavily on which installer and which distributor your installer uses for SolaX parts.
Questions to ask a SolaX installer
- Is this the G4 (current generation) or earlier G3 model?
- Do you register the inverter on SolaX Cloud within 30 days for the 10-year warranty extension?
- Are you quoting the SolaX T-BAT battery, or a third-party battery paired with the X-Hybrid?
- How many SolaX installations have you completed in Perth, and who do you contact for warranty claims?
- What is the inverter's thermal de-rating specification — where will it be wall-mounted on this property?
SolaX is a credible mid-tier option for Perth buyers who want a hybrid inverter with more battery flexibility than Sungrow's SBR-locked ecosystem. The main constraint is installer depth — fewer Perth technicians are SolaX-experienced compared to Sungrow. Get competing quotes including at least one Sungrow quote to benchmark the price difference.
