What Ammonit does

Ammonit Measurement GmbH is a privately-held German engineering company, founded in 1989 and headquartered in Berlin, that designs and supplies measurement systems for the renewable energy industry. Its portfolio centers on the proprietary Meteo-40 plus family of rugged data loggers (variants Meteo-40S plus, Meteo-40M plus, and Meteo-40L plus, differentiated by channel count and storage) and the Meteo-42 / Meteo-42A Solar Data Loggers, which together ingest analog, pulse, and serial inputs from cup anemometers, ultrasonic anemometers, wind vanes, pyranometers, pyrheliometers (including the integrated EKO MS-57), temperature/humidity, air pressure, precipitation, and soiling sensors, as well as LiDAR remote-sensing devices. Loggers are IEC 61400-12-1:2017 and IEC 61724-1:2021 compliant for power performance and solar monitoring applications, and the company operates its own wind tunnel and a DAkkS-accredited calibration laboratory to deliver traceable measurement certificates.

The company's value proposition bundles hardware with a proprietary cloud stack — AmmonitOR Data Cloud (SCP-based ingestion), AmmonitConnect (SSH reverse-tunnel remote access), AmmonitVerify (data validation), and Ammonit Live Dashboard (real-time visualization) — supported by accessories (communication systems, obstacle lights, overvoltage protection, steel cabinets, power supplies) and calibration services. Revenue is generated through enterprise hardware sales, recurring online-service subscriptions, and professional calibration services, with pricing handled on a quote basis and distribution executed through a direct sales channel and a global partner network spanning most countries. Customers are wind and solar farm developers, turbine manufacturers, and utilities that require IEC-compliant, bankable measurement data for site assessment, turbine power curve verification, and operational plant monitoring across wind, solar, remote sensing (LiDAR), and dynamic line rating applications.

Product overview

Ammonit Measurement GmbH offers a comprehensive, modular measurement system portfolio for the renewable energy industry, centered on its Meteo-40 plus and Meteo-42 data logger families. The Meteo-40 plus family comprises three variants — Meteo-40S plus (compact), Meteo-40M plus (medium), and Meteo-40L plus (large) — differentiated by channel count and storage capacity, all supporting inputs for anemometers, ultrasonic anemometers, wind vanes, pyranometers, pyrheliometers, temperature/humidity sensors, air pressure sensors, and precipitation sensors, with IEC 61400-12-1:2017 compliance for power performance measurements. The Meteo-42 and Meteo-42A Solar Data Loggers target solar-specific measurement campaigns. Complementing the data loggers, Ammonit provides a suite of online services including AmmonitOR Data Cloud (SCP-based cloud data ingestion), AmmonitConnect (SSH reverse-tunnel remote access), AmmonitVerify (data verification), and Ammonit Live Dashboard (real-time visualization). The product ecosystem also includes wind and solar sensors (anemometers, ultrasonic anemometers, wind vanes, pyranometers, pyrheliometers, sun tracking systems, soiling sensors), LiDAR remote sensing devices, DAkkS-accredited calibration services, and accessories (communication systems, obstacle lights, overvoltage protection, steel cabinets, power supplies). Ammonit's customers benefit from a global partner network, with systems designed for wind resource assessment, power performance measurements, wind/solar park monitoring (SCADA), and solar resource assessment across small, medium, large, and CSP power plant configurations.
