SOLAX

Key features: 3.0kW output, dual MPPT, up to 6kWp PV input, IP66 enclosure.

SolaX X1-BOOST G4 3.0kW Single-Phase String Inverter is a smart residential option for smaller to mid-sized home solar systems that need more flexibility than a single-MPPT entry inverter. With two MPPTs and a compact wall-mounted design, it suits domestic installs where roof layout benefits from separate tracking channels.

This version supports up to 6kWp of recommended PV input, 200% oversizing, a 40 to 560V MPPT range and 16A input current per tracker. It also brings Type II surge protection on AC and DC, export control capability, WiFi and app-based setup, and an IP66 housing for practical residential installation.

Why buy it: a well-balanced dual-MPPT inverter for homes that want more design flexibility, current protections and strong PV headroom without oversizing the system.

Key features: 3.68kW output, dual MPPT, up to 7.2kWp PV input, IP66 enclosure.

SolaX X1-BOOST G4 3.6kW Single-Phase String Inverter is one of the most useful sizes in the range for everyday UK residential solar. It gives homeowners more output headroom than the 3.0kW version while keeping the same dual-MPPT flexibility, compact format and straightforward single-phase design.

With support for up to 7.2kWp of recommended PV input, 200% oversizing, 16A input current per MPPT and a 40 to 560V operating window, it is well matched to modern domestic panel layouts. Type II surge protection on AC and DC, export control capability, WiFi and app setup and an IP66 housing add further practical value.

Why buy it: a strong all-round home solar inverter that combines useful output, dual-tracker flexibility and current protection features in a compact chassis.

Key features: 6.0kW output, dual MPPT, up to 12kWp PV input, IP66 enclosure.

SolaX X1-BOOST G4 6.0kW Single-Phase String Inverter is the highest-output model in this BOOST set, aimed at larger domestic single-phase systems where roof area and generation goals are well beyond entry-level home solar. It keeps the same dual-MPPT design and current platform features, but with much more array headroom.

This model supports up to 12kWp of recommended PV input, 200% oversizing, a 40 to 560V MPPT range and 16A input current per tracker. Type II surge protection on AC and DC, export control capability, WiFi setup and an IP66 chassis make it a serious single-phase residential option.

Why buy it: the strongest choice in the BOOST family for larger single-phase home solar arrays that need substantial PV support without moving to a more complex inverter platform.

Key features: 8.0kW output, 3 MPPTs, up to 16kWp PV input, IP66 enclosure.

SolaX X1-SMART G2 8.0kW Single-Phase 3-MPPT String Inverter is a higher-capacity residential inverter for larger single-phase solar systems that need more tracking flexibility than a standard two-MPPT model. With three separate MPPTs, it is especially well suited to homes with multiple roof sections or more segmented array design.

This version supports up to 16kWp of recommended PV input, 200% oversizing, 110% AC overloading and up to 20A input current per MPPT. Type II surge protection on AC and DC, rapid shutdown readiness, advanced communication options and IP66 protection help position it as a premium domestic inverter platform.

Why buy it: a powerful single-phase inverter for larger homes that need triple-MPPT flexibility, strong PV headroom and more advanced monitoring and system control.

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.
