        SolaX X1-MINI-1.5K-G4  | 1.5kW X1-Mini G4 Solar Single-Phase Inverter | MPPT

        The SolaX X1-MINI-1.5K-G4 is a compact single-phase grid-tied inverter designed for small-scale residential solar systems. It delivers 1.5kW rated AC output and supports up to 3kWp of PV input, allowing 200% oversizing to maximise yield with high-power panels.

        Its ultra-wide MPPT window (40–520V) with global MPP scan ensures optimum power tracking across varied conditions, ideal for rooftops with multiple orientations or intermittent shading. The G4 series also includes Type II SPD on both AC and DC sides, IP66 weather protection, and optional AFCI support for advanced safety.

        It offers built-in export control, supports parallel connection of up to 5 inverters without the need for an external EMS, and integrates with smart loads like EV chargers and heat pumps. Remote monitoring is enabled via SolaXCloud with 10-second refresh rate and IV curve scanning for efficient diagnostics.
