Our plug-and-play modules are fully automatic and, thanks to state-of-the-art collective intelligence technology, require no maintenance or intervention from our customers. The SEMS system embodies Swiss engineering excellence: in addition to monitoring multiple energy sources (electricity, water, gas, heat, heating oil, etc.), it optimizes energy consumption by reducing power peaks and preventing energy waste in electrical systems.
SEMS also integrates the intelligent control of battery storage systems to maximize the self-consumption of solar energy and create the energy flexibility required for grid regulation.This is financially supported by Swissgrid.
