Single Phase Solar Inverter

Key features: 1.5kW output, up to 3kWp PV input, 40-450V MPPT range, IP66 enclosure.

SolaX X1-MINI G4 1.5kW String Inverter with WiFi and AFCI is a compact single-phase on-grid inverter aimed at smaller residential solar systems that need more breathing room than the 1.1kW version without moving to a larger frame size. It is well suited to straightforward domestic arrays on modest roof space.

This model supports up to 3kWp of recommended PV array power, 200% DC oversizing and a 50V start-up voltage, while also bringing Type II surge protection on AC and DC, export control capability and a weather-resistant IP66 housing.

Why buy it: a smart middle-ground option for homes that want a compact inverter with more array headroom, modern protections and easy monitoring.

Key features: 2.5kW output, up to 5kWp PV input, 40-550V MPPT range, IP66 enclosure.

SolaX X1-MINI G4 2.5kW String Inverter with WiFi and AFCI is the highest-output option in this trio, aimed at larger small-to-mid domestic solar systems that still want the compact X1-MINI G4 format. It remains a single-phase, one-MPPT inverter, but this version adds materially more PV headroom and a wider operating window.

With support for up to 5kWp of recommended PV input, 200% DC oversizing, a 50V start-up voltage and a 40 to 550V MPPT range, it is well suited to homes using modern higher-output modules on simple roof layouts.

Why buy it: an excellent choice for homeowners who want the biggest array headroom available in the compact X1-MINI G4 platform without moving into a larger inverter family.
