SolaX X3-MEGA G2 60kW Three-Phase String Inverter

The highest-capacity option in this X3-MEGA G2 set

SolaX X3-MEGA G2 60kW Three-Phase String Inverter is intended for the largest commercial and industrial solar projects in this part of the range. It is designed for sites where roof area, module count, tracker requirements and overall generation targets are all well beyond typical commercial solar sizes. Warehouses, factories, large agricultural buildings and similar three-phase premises are the kind of environments this inverter is built for.

What makes it particularly significant is that it combines the family’s highest output with its highest MPPT count. That means the 60kW version is not merely a bigger number on the label. It is the option for projects where both system scale and array segmentation genuinely demand more from the inverter platform.

Why the 60kW version matters

This model supports up to 90kWp of recommended PV input and uses six MPPTs with two strings per tracker. That gives installers far more flexibility when designing across complex or expansive commercial roofs. It also allows stronger control over string grouping and tracker allocation, which can make a meaningful difference on larger sites with multiple roof sections or varying orientations.

On top of that, the inverter supports 150% PV oversizing and 110% overload output. Those figures are commercially valuable because they allow the DC side of the system to be designed more assertively while still staying within a single, well-specified inverter platform. For larger commercial solar, that sort of headroom matters.

Key technical strengths

• 60kW rated three-phase output
• Up to 90kWp recommended PV input
• Six MPPTs with two strings per tracker
• 150% PV oversizing and 110% overload output
• 180 to 1000V MPPT range with 200V start-up voltage
• 32A maximum input current and 46A short-circuit current per MPPT
• Type II SPD on both AC and DC
• Built-in export power control
• Remote setting and upgrading support
• Smart I-V curve diagnosis and smart string monitoring

These specifications are aimed squarely at large three-phase solar work. The MPPT count is especially important because that is what makes the inverter so useful on segmented commercial roofs. The strong current handling per tracker also keeps the model aligned with current high-power commercial modules rather than older, lower-current assumptions.

Monitoring, diagnostics and site management

The X3-MEGA G2 60kW is built with remote operation and long-term visibility in mind. It supports remote setting and upgrading, smart string current monitoring, I-V curve diagnosis and multiple communications options. On large commercial sites, those capabilities help reduce service time, improve fault tracing and make ongoing performance oversight far more manageable.

Export control is also a major advantage at this scale. Larger commercial systems are more likely to need export limitation or planned grid interaction from the outset, and having that built into the inverter platform makes system design and compliance easier to manage.

Protection, cooling and physical robustness

Protection is strong throughout the X3-MEGA G2 family, and this 60kW version reflects that. Type II surge protection on AC and DC is supported by a wider set of commercial safety functions including grid monitoring, anti-islanding protection, over-current protection, over-temperature protection and string fault detection. Optional AFCI support is also available where required by the project brief.

The inverter uses smart fan cooling and an IP66 enclosure, making it suitable for demanding outdoor and semi-exposed commercial installations when sited correctly. With dimensions around 630 x 521 x 286 mm and a weight of roughly 45.5kg, it remains practical for installers dealing with higher-output commercial hardware.

Who it suits best

This model is best suited to very large commercial rooftops, industrial premises, large agricultural buildings and other substantial three-phase sites where both PV capacity and array complexity are high. It is particularly relevant where six MPPTs make a real difference to design clarity and system optimisation.

Compared with the 40kW and 50kW variants, this is the clear choice when the project is not only larger, but also more segmented or more demanding in terms of tracker allocation. It is the right option when the site genuinely calls for the maximum capability in this family.

Final view

SolaX X3-MEGA G2 60kW Three-Phase String Inverter is the most capable option in this set for very large commercial and industrial solar projects. With support for up to 90kWp of PV input, six MPPTs, 150% oversizing, 110% overload output, export control, Type II SPD on AC and DC, strong diagnostics and IP66 protection, it delivers the scale, flexibility and connected functionality that larger three-phase sites need.
