Maximum efficiency for your own consumption

With a peak efficiency of 98%, the X1-MINI-2.5K-G4 is one of the most efficient single-phase small inverters in its class. Even in low sunlight or at partial load, it operates with high efficiency, increasing your self-consumption. Thanks to the possibility of DC oversizing by up to 200%, you can connect significantly more PV modules than the AC rated power specifies – for early power production in the morning, reliable yields in diffuse light, and an overall higher energy yield.

Ultra-wide MPPT range & shading optimization

The MPPT voltage range of 40–550 V enables high yields throughout the day. Global MPP tracking with shading optimization also ensures that maximum energy is generated even in partial shade.

Smart control via app, pocket WiFi + LAN

The integrated Pocket WiFi and LAN connection give you maximum flexibility in terms of connectivity. Via the SolaX Cloud, you can conveniently monitor your system via smartphone or PC, analyze yield data, or adjust settings—all with 10-second data updates.

Intelligent load management

The X1-MINI-G4 supports intelligent load management, enabling the targeted control of consumers such as heat pumps, wall boxes, or other smart devices. This ensures that self-generated solar power is used optimally, peak loads are avoided, and the share of self-consumption is sustainably increased – for maximum efficiency and lower energy costs.

Robust, quiet, and safe

The IP66-certified housing protects against dust and water, so outdoor installation is no problem. The absence of a fan reduces noise and maintenance costs. With integrated Type II surge protection on the AC and DC sides, rapid shutdown preparation, and optional AFCI function, you are also well protected.

Comprehensive protection functions

Maximum safety is guaranteed with active anti-islanding protection, integrated type II surge protection on the AC and DC sides, and an optional arc fault circuit interrupter (AFCI). Rapid shutdown preparation provides additional protection, while numerous other safety mechanisms such as overvoltage and undervoltage protection, DC isolation protection, grid and DC feed monitoring, reverse polarity protection, Regenerative power monitoring, fault current detection, overtemperature protection, ground fault protection monitoring, string fault detection, AC overcurrent protection, and AC short-circuit protection ensure reliable operation under all conditions.
