Kaco blueplanet 125 NX3 M10 WM OD IIGL

Kaco blueplanet 125 NX3 M10 string inverter (Version L with arc detection)

The blueplanet 125 NX3 is a three-phase multi-MPPT string Inverter with a capacity of 125 kVA for commercial and industrial Photovoltaic systems – developed and manufactured in Germany. With 10 MPP trackers (2 strings each), up to 200 per cent DC overloading and global MPP tracking, it is suitable for large and complex roof areas as well as for retrofitting projects. SiC technology ensures an efficiency of up to 99.1 per cent and very late temperature derating. The L (IIGL) version is also equipped with integrated arc detection and interruption in accordance with IEC 63027.

This is a project-specific product. Please contact your sales representative for quantity planning and project pricing.
