Lewiz is a DIN-rail mounted module installed in the home monitoring and actively steering energyflows from solar panels, batteries, heat pumps, heat storage and EV chargers. Using Lewiz mobile app home owners can select optimization schemes to maximize self-consumption, minimize capacity peaks, enable dynamic pricing, or any combination thereof. Lewiz’ secure European-wide cellular communication enables it to add additional optimization schemes (use-cases) at any time depending the needs and use in any country. Lewiz operates brand-independently using open standards to connect other brands of EV chargers, inverters and heatpumps.
