Three Phase Solar Inverter

Key features: 40kW output, up to 60kWp PV input, 4 MPPTs, IP66 enclosure.

SolaX X3-MEGA G2 40kW Three-Phase String Inverter is a commercial three-phase inverter for larger rooftop and ground-mounted PV systems that need far more flexibility than residential hardware can provide. This 40kW version combines four MPPTs, two strings per tracker and built-in export control in a compact high-density format.

It supports up to 60kWp of recommended PV input, 150% oversizing, 110% overloading output, a 180 to 1000V MPPT range and up to 32A input current per MPPT. Type II surge protection on AC and DC, smart diagnostics and remote management support all add to its commercial appeal.

Why buy it: a strong fit for commercial projects that need genuine three-phase inverter capability, flexible MPPT design and modern monitoring without stepping up to a larger model than the site requires.

Key features: 50kW output, up to 75kWp PV input, 5 MPPTs, IP66 enclosure.

SolaX X3-MEGA G2 50kW Three-Phase String Inverter is a commercial and industrial inverter for larger PV systems that need more tracking flexibility and PV headroom than the 40kW model. This version steps up to five MPPTs, two strings per tracker and a higher supported array size for more ambitious rooftop and ground-mounted projects.

It supports up to 75kWp of recommended PV input, 150% oversizing, 110% overloading output, a 180 to 1000V MPPT range and up to 32A input current per MPPT. Built-in export control, smart string monitoring, remote management and Type II surge protection on AC and DC all add practical commercial value.

Why buy it: a strong step up for sites that need extra MPPT flexibility and larger PV support while still keeping the system within one compact commercial inverter platform.

Key features: 60kW output, up to 90kWp PV input, 6 MPPTs, IP66 enclosure.

SolaX X3-MEGA G2 60kW Three-Phase String Inverter is the largest variant in this group, built for very high-output commercial and industrial PV systems that need maximum tracker flexibility and substantial PV support. This version combines six MPPTs, two strings per tracker and the highest supported array size in the family.

It supports up to 90kWp of recommended PV input, 150% oversizing, 110% overloading output, a 180 to 1000V MPPT range and up to 32A input current per MPPT. Built-in export control, smart diagnostics, remote management, Type II surge protection and IP66 protection all reinforce its commercial focus.

Why buy it: the strongest choice in this set for very large commercial solar systems that need maximum MPPT flexibility, strong DC headroom and a modern connected inverter platform.
