KACO new energy

What KACO new energy does

KACO new energy GmbH is a German manufacturer of solar PV inverters headquartered in Neckarsulm, with R&D in Kassel and a logistics centre in Erlenbach. Founded in 1998/1999 as a spin-off of the 1914-established KACO group, the company sells string inverters, hybrid inverters and battery storage inverters under the blueplanet brand, spanning residential (NX1, NX3, NH3 hybrid), commercial and industrial (TL3 60–125 kW) and utility-scale (125–360 NX3 TL3) segments. Its technology stack is built around silicon-carbide (SiC) wide-bandgap semiconductors, delivering inverter efficiency up to 98.9%, power density above 2 kVA/kg, anti-PID float-controller integration, grid-forming capability, and a "Virtual Central System" design approach that the company documents as delivering 8–10% CAPEX savings versus distributed architectures. The blueplanet monitoring platform (smartcloud, web pro, web public) and the myKACO.com customer portal wrap the hardware with telematics, backup-power certificate licensing, an inverter-exchange service promising 48-hour EU delivery, and preventive-maintenance offerings.

KACO has been a wholly-owned subsidiary of Siemens AG since 30 April 2019, operating within Siemens Smart Infrastructure as the specialist for decentralised power electronics. The business is monetised primarily through hardware sales via a global network of authorized distributors (Krannich, EWS, Altitude Energy) and Siemens-affiliated service partners, complemented by direct sales from Neckarsulm and an online self-service portal for service, warranty, and replacement inverters. Recurring revenue streams include professional services (commissioning, warranty extensions, preventive maintenance), monitoring subscriptions (blueplanet web pro, smartcloud freemium) and one-time software license fees (backup power certificates). Customer reach spans utilities and infrastructure (EnBW, Kibbutz Maale-Gilboa industrial storage), system integrators (KNE Systemhaus, GSW), and specialized installers across more than 20 countries in Europe, the Americas, Asia, Africa and the Middle East. The company holds ISO 9001, 14001, 45001, 50001 and 27001 certifications, is EU RED cybersecurity compliant, and has been awarded Top Brand PV in Germany four consecutive years (2021–2024).
