About ELTEDO
ELTEDO – Elektrotechnik Christian Donislreiter is a registered specialist electrical business based in Tüßling (Altötting district), founded in 2014 as a master-certified business after successfully passing the master craftsman examination before the Chamber of Crafts for Munich and Upper Bavaria. The company plans and installs complete electrical systems for new builds, renovations and commercial projects, including meter cabinet distributions, RCD/circuit protection, earthing and lightning protection connections. Further focal points are KNX smart home building automation (design and commissioning with ETS), turnkey photovoltaic systems with optional battery storage including grid operator registration, air conditioning systems from split to VRF systems performed by F-gas-certified personnel, and structured network technology with glass fibre (fibre optic) including splicing service and OTDR measurement. Lighting technology is implemented with energy-efficient LED technology and control via KNX or DALI. The service portfolio is rounded off by maintenance, inspection and fault analysis for electrical, PV and air conditioning systems. Customers include private households, commercial enterprises, industry and municipal buildings in the Altötting district and the Mühldorf am Inn area; the company realises around 100 projects per year from a single source.
