• Single-family homes and outbuildings with low power consumption
• Balcony installations & confined spaces

Maximum efficiency for your self-consumption

With a peak efficiency of 98%, the X1-MINI-3.3K-G4 is one of the most efficient single-phase small inverters in its class. Even in low sunlight or under partial load, it operates highly efficiently, thereby increasing your self-consumption. Thanks to the option for DC oversizing by up to 200%, you can connect significantly more PV modules than the AC rated power specifies—for early morning power generation, reliable yields in diffuse light, and a higher overall energy yield.

Ultra-wide MPPT range & shading optimization

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

Smart Control via App, Pocket WiFi + LAN

With the integrated Pocket WiFi and LAN connection, you have maximum flexibility in 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 targeted control of appliances such as heat pumps, wallboxes, or other smart devices. This ensures optimal use of self-generated solar power, avoids peak loads, and increases the share of self-consumption—for maximum efficiency and lower energy costs.

Robust, Quiet, and Safe

The IP66-certified housing protects against dust and water, making outdoor installation a breeze. The absence of a fan reduces noise and maintenance costs. With integrated Type II surge protection on both the AC and DC sides, Rapid Shutdown readiness, and an optional AFCI function, you’re also fully protected.

Comprehensive Protection Features

With active anti-islanding protection, integrated Type II surge protection on both the AC and DC sides, and an optional arc fault circuit interrupter (AFCI), maximum safety is guaranteed. Rapid Shutdown readiness provides additional protection, while numerous other safety mechanisms—such as overvoltage and undervoltage protection, DC isolation protection, grid and DC feed-in monitoring, reverse polarity protection, feed-back current monitoring, ground fault detection, overtemperature protection, ground fault protection monitoring, string fault detection, AC overcurrent protection, and AC short-circuit protection ensure reliable operation under all conditions.
