Due to the design and dimensions - the height above the ground level is only 1700 mm and the low weight - including the ~ 8T transformer, a station dedicated to large-scale photovoltaic installations - installation between the tables with panels. The station is mounted on a concrete foundation and can be transported as a whole, including the transformer.
