Siemens KACO blueplanet NX3-M2 15kW

KACO inverters combine German quality with global innovation – since 2019, the KACO new energy brand has been part of the Siemens Group, ensuring that each device benefits from the experience, technical support, and highest technological standards of the automation and energy market leader.

Discover the modern KACO blueplanet NX3-M2 inverter with a power output of 15 kW, designed for efficient operation in both residential and commercial installations. This advanced inverter from the German manufacturer combines high efficiency, safety, and intuitive operation.

The device is equipped with two independent MPPT trackers, allowing for optimal energy management from modules positioned at different angles or on different roof surfaces. This ensures maximum energy yield even in less common photovoltaic configurations.

The 15 kW output allows for the operation of large PV systems, and a high efficiency of up to 97.8% ensures minimal energy conversion losses. The robust, IP65-rated aluminum housing provides resistance to dust, moisture, and variable weather conditions, allowing for both indoor and outdoor installation.

The KACO blueplanet NX3-M2 inverter is equipped with a full suite of safety features, including surge protection (DC and AC), Wi-Fi and RS485 monitoring, and an intuitive user interface that allows for quick access to key device parameters.

The modern, fanless design ensures quiet operation and years of trouble-free use. The compact size and lightweight housing facilitate quick installation by both professional installers and advanced users.
