About Autarke Energieversorgung
Autarke Energieversorgung is a one-man business in Irsee in the Allgäu region, specialising in autonomous power supply. The business develops and produces high-quality, durable lithium iron phosphate battery packs (LiFePO4) and manufactures compact OFF-GRID systems in case form with DC-AC sine inverters, MPPT solar charge controllers, low-voltage protection and a wide range of outputs (230 V, 12 V, USB). The portfolio includes home power stations, off-grid systems with PV, small wind turbines, Stirling engines and generator backup, as well as mobile systems for motor homes, recreational vehicles and tiny houses. In addition, the company offers system planning, circuit diagram creation, component dimensioning, on-site installation (preferably within a 100 km radius of Irsee), energy consulting, electrical engineering prototype construction, metrological and building biology investigations, and remote monitoring via the Victron VRM portal. Reference systems are in operation, among other places, in Norway and on Crete.
