What the SolaX X3-Pro G2 10kW is designed to do

SolaX X3-Pro G2 10kW Three-Phase String Inverter is built for larger residential solar systems on three-phase supply where array size, yield expectations and roof layout all point toward a more capable inverter. It sits in a particularly useful part of the X3-Pro G2 family because it delivers a meaningful uplift over the 8kW model while keeping the same dual-MPPT structure, the same residential on-grid positioning and the same platform features that make the range commercially attractive.

That makes the 10kW variant relevant for homes with more roof space, stronger daytime electricity demand or a broader electrification plan that includes solar alongside loads such as heat pumps and EV charging. Rather than overspecifying the inverter, it allows the system to be sized more proportionately for domestic projects that have clearly moved beyond the lower end of three-phase solar design.

Why the 10kW version matters

The real advantage of the 10kW model is not simply that it carries a larger output number. It supports up to 15.0kWp of recommended PV array power, which gives installers and buyers more design headroom for higher-wattage modules and more ambitious residential arrays. Rated output power is 10kW, rated output current is 15.2A and maximum output apparent power is 11.0kVA. Those figures help place the inverter in a sweet spot for many larger homes where a serious three-phase PV system is needed but the jump to 12kW or above would be unnecessary.

That balance makes the 10kW model commercially useful. It is big enough for substantial domestic systems, but it does not assume the extreme roof area or load profile that the larger variants are better suited to. For many homes, that means a cleaner technical fit and a more proportionate budget.

Key features and practical benefits

• 10kW rated three-phase output for larger residential PV systems
• Up to 15.0kWp recommended PV array power
• 150% DC oversizing and 110% AC overloading output
• Dual MPPT arrangement for more flexible residential roof design
• Up to 32A input current and 40A short-circuit current per MPP tracker
• 160 to 980V MPPT range with 200V start-up voltage
• Type II SPD on AC and DC sides
• Built-in export power control and built-in global MPP scan
• IP66 ingress protection and optional AFCI support

Those features matter because they help the inverter work well on real homes rather than only on paper. Dual MPPT tracking is valuable where the array spans two main sections. The 32A per MPP tracker rating gives strong compatibility with current high-power, higher-current modules. Built-in export control adds design flexibility where grid export needs to be limited or monitored more closely.

Technical detail that matters in practice

Shared core electrical figures across these X3-Pro G2 models include a maximum PV input voltage of 1100V, rated PV input voltage of 650V and operating voltage range of 135 to 985V. MPPT operating window is 160 to 980V and start-up voltage is 200V. The 10kW model then builds on that platform with its own output level, giving a stronger three-phase residential option without changing the basic system logic installers will already understand from the family.

Protection functions listed in the datasheet include active anti-islanding, over and under voltage protection, DC isolation protection, DC reverse-polarity protection, grid monitoring, DC injection monitoring, back-feed current monitoring, residual current detection, over-temperature protection, AC overcurrent protection and AC short-circuit protection. SolaX also lists certifications including EN 50549, VDE4105, IEC 61727, IEC 62116, IEC 61683, IEC 60068 and IEC/EN 62109-1 and -2. That gives the model the technical grounding expected of a current residential three-phase inverter.

Monitoring, control and connected use

The X3-Pro G2 family is designed as more than a simple converter. Product literature highlights 24-hour monitoring through WiFi, LAN and 4G options, plus smart loads management for applications such as heat pumps and smart EV chargers. On a higher-output domestic system, those features are especially useful. They make it easier for owners and installers to monitor production and integrate solar more intelligently with the rest of the property’s electrical loads.

Built-in export power control is another major advantage. For some residential projects, export management is a key part of the design brief. The ability to support that natively within the inverter platform makes the 10kW variant more attractive than a simpler unit that would need more workaround hardware or a less tidy configuration path.

Installation and system design considerations

Dimensions are 482 × 417 × 186 mm and the inverter carries an IP66 rating, so it is suited to exposed installation environments where best-practice siting is followed. Operating temperature range is -30 to 60°C and maximum operating altitude is 4000m. Communication interfaces are listed as RS485 and DRM, with optional meter support. Night-time consumption is under 3W. Those details help confirm that the inverter is built for real domestic deployment rather than only for showroom specification.

The 10kW version is particularly attractive where a three-phase home has enough roof area to build out a meaningful PV array but still wants to keep the project within a clearly residential inverter class. It offers a cleaner fit than undersizing the inverter, and a more proportionate fit than jumping too early to the larger models.

Who this variant suits best

The X3-Pro G2 10kW is well suited to larger three-phase homes, residential PV systems up to 15.0kWp DC, households with higher daytime electricity use and projects where dual-MPPT flexibility and export-control capability are both important. It also makes sense for homes that are combining solar with heat pump or EV charging plans and want the inverter platform to support that wider energy picture.

Compared with the 8kW model, the 10kW version offers a clear uplift in array headroom. Compared with the 12kW, 15kW and 20kW models, it remains a more measured choice where the system brief is substantial but not extreme. That is why it lands so well in the range.

Final view

SolaX X3-Pro G2 10kW Three-Phase String Inverter is a very strong residential three-phase option for homes stepping beyond the lower-output bracket. With up to 15.0kWp recommended PV support, dual MPPTs, 150% DC oversizing, 110% AC overloading, Type II SPD on AC and DC, export power control, built-in global MPP scan and IP66 protection, it gives larger homes a capable and commercially sensible solar inverter platform.
