About AmpX
AmpX GmbH is an online supplier specialising in energy measurement, logging and analysis technology, based in Georgenthal (Thuringia). The product range includes portable and installed three-phase energy loggers and power quality analysers (including Meatrol Mi550, ME440, ME435, ME537, MQ31), Rogowski coils, current transformers, MID-certified energy meters, IoT energy monitoring systems (PSsystec Cumulocity) as well as test devices for the solar industry from manufacturers such as Sonel, HT Instruments and Uni-T. In addition, AmpX offers technical support, repairs and spare parts, calibration certificates, visualisation and analysis tools such as Excel templates, the AmpX Energy Portal and Spacewell Energy (Dexma). The products are used for load profile recording, peak load and unbalance analysis, harmonic analysis up to the 51st order (IEC 61000-4-30 Class S), the planning of PV and backup systems as well as the evaluation of energy efficiency projects. Originating from the solar company Green Energy Solutions founded in 2010, AmpX expanded to Germany in 2024 and supplies electricians, solar installers, engineers and energy managers across Europe from its warehouses in Germany as well as in South Africa.
