What the SolaX X3-MEGA G2 60kW is

SolaX X3-MEGA G2 60kW Three Phase Inverter is the largest three-phase inverter in the X3-MEGA G2 series. The exact model in this row is X3-MEGA-60.0-G2, which sits above the 40kW and 50kW versions in output, tracker count and maximum recommended array size. That matters because it makes the 60kW version the right family choice when the project needs the most string flexibility and highest DC capacity available within the MEGA G2 line.

In practical terms, this is a commercial and industrial inverter for serious rooftop or ground-adjacent array work, not a lightly enlarged domestic product. It is designed around three-phase installations, multi-MPPT array planning, export-aware control and long-term remote maintenance visibility.

Who it suits

The 60kW X3-MEGA G2 suits warehouses, agricultural buildings, industrial units, retail parks, schools and other commercial sites with larger PV ambitions and more complex array layouts. It is especially useful where the PV field is broken across multiple roof planes or where the designer wants the maximum number of trackers available in this family to keep strings better separated by orientation or behaviour.

It also suits projects that want to keep inverter count down while still maintaining strong string flexibility. A single 60kW inverter with six MPPTs can simplify some commercial designs compared with multiple smaller units, depending on the layout and electrical strategy.

Key features and practical benefits

• 60kW rated AC output for larger three-phase commercial systems.
• Up to 90kWp maximum recommended PV array power.
• Six MPPT trackers with two strings per tracker.
• 32A maximum input current per MPPT.
• 150% PV oversizing and 110% overload output support.
• 180V to 1000V MPPT voltage range and 1100V maximum PV input voltage.
• Built-in export power control.
• Remote setting and upgrading.
• I-V curve diagnosis and string current monitoring.
• 24-hour operation monitoring support.
• IP66 protection and smart cooling.
• Optional Type II SPD on AC and DC sides and optional AFCI.

The biggest advantage is string design freedom. Six MPPT trackers give the 60kW model the most array flexibility in the MEGA G2 family, which is valuable on commercial roofs that are segmented, interrupted or mixed in orientation. That can help improve performance consistency and reduce compromises in how strings are grouped.

The second advantage is project scale. With a 90kWp maximum recommended PV array size, the inverter is better suited to high-capacity commercial systems than the smaller variants. That makes it more relevant where the site wants substantial generation from a single inverter position.

Technical details that matter in practice

The official X3-MEGA G2 datasheet lists the 60kW model at 90kWp maximum recommended PV array power, 1100V maximum PV input voltage, 600V nominal PV input voltage, 200V to 1000V operating voltage range and 180V to 1000V MPPT voltage range. The same datasheet confirms six MPPT trackers with two strings per tracker, 32A maximum input current per MPPT and 46A maximum short-circuit current per MPPT.

On the AC side, the inverter is listed at 60kW rated output power, 66kVA maximum output apparent power and 100A or 95.7A maximum output continuous current depending on grid voltage. Maximum efficiency is 98.4% and European efficiency is 98.1%. The enclosure is IP66 rated, the cooling concept is smart cooling and communication interfaces are listed as RS485, DRM and meter. Dimensions are 630 x 521 x 286mm and the net weight is 45.5kg.

Those figures are commercially important because they show the 60kW model is not simply a small step above the 50kW version. It increases array headroom, adds a sixth MPPT tracker and remains in a chassis that is still manageable compared with some larger commercial inverter classes.

Installation and fitment considerations

The 60kW X3-MEGA G2 should be specified where the array size, site load profile and three-phase infrastructure justify a larger C&I inverter. The six-MPPT layout is especially valuable on irregular or highly segmented rooftops where tracker count becomes a design constraint. On more straightforward roofs, the main benefit may be capacity rather than layout flexibility.

Because the inverter includes built-in export power control and remote configuration functions, it also suits projects where commissioning, DNO interaction or long-term performance management need to be handled more actively. Optional SPD and optional AFCI should still be specified correctly rather than assumed as standard.

The IP66 enclosure and smart cooling support outdoor mounting where appropriate, but the overall installation should still be treated as a commercial electrical project with the expected attention to access, ventilation and maintenance planning.

Why this exact variant may be the right choice

The X3-MEGA G2 60kW is the right choice when the project needs the most capable inverter in the MEGA G2 family. Compared with the 50kW version, it adds another MPPT tracker and increases maximum recommended PV array size from 75kWp to 90kWp. Compared with the 40kW model, it provides materially more capacity and far more design freedom for complex roofs.

That makes the 60kW version especially attractive for commercial sites that want to maximise system size without splitting the project into multiple smaller inverter positions unless there is a design reason to do so.
