Wallner Automation developed the energy controller "VoltoPlus" that enables the optimised use of surplus generated PV electricity for own consumption. The device works independently from the inverter, electricity metre or pulse generator. Thanks to the integrated measuring unit, VoltoPlus can detect the currents, voltages and capacities and switch the different energy flows accordingly.
