Open installation based on the SmartEnergy + DC 5048VS for a residential house in Karlsruhe. The system consists of an XTH8000-48 and 2 VarioStrings, each connected to a 3.5kWp PV generator, an 800Ah OPzV tubular plate battery and sub-distributors (not shown on the picture) with uninterrupted bypass circuit and phase coupling. The system is completely off-grid capable and serves primarily to increase own consumption. During the summer months almost 100% self-sufficiency is achieved with the installed photovoltaics.
