What the SolaX X3-MEGA G2 60kW is designed to do

SolaX X3-MEGA G2 60kW Three-Phase String Inverter is intended for the largest commercial and industrial on-grid solar projects in this family, where roof area, module count and site demand all justify a very substantial inverter. It remains part of the commercial and industrial string inverter category rather than a utility-scale solution, which makes it especially relevant for large warehouses, industrial units, agricultural buildings, factories and similar three-phase sites that need serious PV capacity within a familiar commercial architecture.

The 60kW version is important because it combines high rated AC output with the family’s maximum MPPT count. That means it does not simply offer more power. It also offers more freedom in how the array is divided and managed. For larger commercial designs, that can be the deciding factor. More MPPTs make it easier to keep strings logically organised, particularly where the roof is segmented, orientation varies or the system spans multiple grouped areas.

Why the 60kW variant matters

This model supports up to 90kWp of recommended PV array input power and uses six MPPTs with two strings per tracker. That is the highest PV allowance and the greatest MPPT flexibility in this set. For many large commercial projects, that is exactly what makes it the right choice. It gives the system enough room to use current high-output modules at a meaningful scale while keeping tracker allocation more granular than the lower-output versions allow.

The inverter also supports 150% PV oversizing and 110% overloading output. That is valuable in commercial design because the DC side of the system is often where installers want more freedom, especially when available roof space is strong and module economics support larger arrays. The 60kW X3-MEGA G2 gives that headroom without forcing the project into a completely different product class.

Key features and practical benefits

• 60kW rated AC output for very large commercial and industrial PV systems
• Up to 90kWp recommended PV array input power
• Six MPPTs with two strings per tracker for maximum family-level design flexibility
• 150% PV oversizing input and 110% overloading output
• 180 to 1000V MPPT range with 200V start-up voltage
• Maximum 32A PV input current and 46A short-circuit current per MPPT
• Built-in export power control and remote setting and upgrading
• Smart I-V curve diagnosis and smart string current monitoring
• Type II SPD on AC and DC sides, with optional AFCI, APS and PLC

These are practical rather than abstract benefits. Six MPPTs make a clear difference on large or complex roof layouts. Strong current handling per tracker keeps the inverter compatible with modern module characteristics. Built-in export control is particularly relevant on large commercial systems where export behaviour is often a more important part of the design brief.

Technical details that matter in practice

The X3-MEGA G2 60kW shares the core family platform of 1100V maximum PV input voltage, 600V nominal input voltage, 180 to 1000V MPPT range and 200V start-up voltage. On the AC side, it is rated at 60kW with maximum apparent power of 66kVA. Rated output current is 90.9A or 87A depending on grid voltage, and maximum AC output current is 100A or 95.7A. These figures show clearly that the inverter is aimed at very high-output three-phase site work rather than general small commercial applications.

Maximum efficiency is 98.4% and European efficiency is 98.1%. AC voltage range is 304 to 460V, nominal AC frequency is 50/60Hz with ±5Hz range, and power factor range is 0.8 leading to 0.8 lagging. THDi at rated power is below 3%. For specifiers, these are the sorts of numbers that help confirm the inverter’s suitability for serious commercial deployment where output, efficiency and grid-side behaviour all matter.

Monitoring, maintenance and connected site management

Commercial systems at this size benefit greatly from stronger operational visibility, and the 60kW X3-MEGA G2 is built with that in mind. SolaX lists remote setting and upgrading, smart I-V curve diagnosis, smart string current monitoring, optional 24-hour operation monitoring and optional PLC. Communication interfaces are RS485, USB and DRM, with Pocket WiFi, Pocket LAN and Pocket 4G listed as optional monitoring dongles. These features help reduce service friction, improve remote oversight and make the inverter easier to manage over time.

Night-time reactive power compensation is another notable platform feature. On larger commercial installations, broader power-management behaviour can matter as much as daytime PV conversion. This reinforces the sense that the 60kW model is designed as a complete commercial system component rather than a simple high-output converter.

Protection, durability and site suitability

Protection is robust across the X3-MEGA G2 range. The 60kW model includes Type II surge protection on both AC and DC sides and the datasheet lists over and under voltage protection, over current protection, DC isolation protection, grid monitoring, DC injection monitoring, residual current detection, anti-islanding protection, string fault detection and over-temperature protection. Optional AFCI support gives another layer where project specification requires it.

IP66 ingress protection supports deployment in exposed commercial environments where best-practice siting is followed. Cooling is described as smart fan cooling, helping support long fan life and dependable thermal control. The family literature also highlights advanced heat dissipation technology that makes the system more than 10% lighter and smaller, which is meaningful for higher-output hardware that still needs to remain practical on site.

Physical installation and fitment

The 60kW inverter measures 630 × 521 × 286 mm and weighs 45.5kg. Operating ambient temperature range is -30 to +60°C, with derating above 45°C, and maximum operating altitude is 4000m with derating above 3000m. Relative humidity is listed as 0 to 100%. These details confirm that the inverter is designed for demanding commercial conditions while staying within a form factor that installers can still manage sensibly.

The six-MPPT layout is one of the biggest practical reasons to choose this model. On very large roofs or grouped commercial arrays, that extra tracker count can make the system cleaner, easier to balance and easier to optimise than it would be with the 40kW or 50kW versions.

Who this inverter suits best

The 60kW X3-MEGA G2 is best suited to very large commercial rooftops, industrial premises, large agricultural buildings and other substantial three-phase sites where PV capacity, array complexity and export-management needs are all high. It is particularly relevant where six MPPTs and 12 string inputs provide the design flexibility the project genuinely needs.

Compared with the 40kW and 50kW models, this version is the clear choice when the site is larger, the array is more segmented or the project simply needs the highest inverter capacity in this family. It is not just the biggest option. It is the right option when the job genuinely demands more output and more MPPT capability.

Final view

SolaX X3-MEGA G2 60kW Three-Phase String Inverter is the highest-capacity option in this family for very large commercial and industrial solar projects. With support for up to 90kWp PV input, six MPPTs, 150% oversizing, 110% overloading output, Type II SPD on AC and DC, export power control, smart diagnostics and IP66 protection, it gives larger three-phase sites a very capable and well-connected inverter platform.
