Smart energy management

Integrated energy management

The integrated energy management system of neeoBASIX analyses generation and consumption data to determine the optimal energy distribution. Direct domestic energy consumption always takes priority. Once the storage is full, additional consumers such as heat pumps, heating elements etc. can be integrated to increase domestic consumption. Thanks to the flexible energy management system, photovoltaic systems can easily be combined with miniature co-generators.


Compact, profitable, safe

Thanks to its extremely compact design, neeoBASIX is easily integrated into any household. Combine it with your own solar-energy system or miniature co-generator and become your own energy manager. The device is extremely easy to operate. It contains only state-of-the- art technologies, which ensures not only maximum safety but also a long service life.
