ElvWiS
You may receive free electricity from your roof or balcony with the help of the ElvWiS micro energy power plant. Private consumers and small enterprises who desire to produce their power, store it locally, and utilize it when necessary can use the autonomous ElvWiS system. It comprises batteries, solar panels, generators, and other parts that you may uniquely customize to meet your demands and budget. Electricity is always available from your own ElvWiS power station, even when there are storms or clouds.
