For the power supply of a larger private domicile in Portugal, a customized solution was developed by our engineers. The heart of the system is the ready-to-operate plug’n’play control cabinet with a total of 14kVA / 230V AC output power and 14kWp maximum PV power. Two Studer Xtender XTH 8000 inverters and two VarioString VS-120 MPPT charge controllers with an input voltage of 600V each were installed. Furthermore, a sealed tubular plate battery from Hoppecke with a total capacity of 1250Ah (C24) / 48V, a PV generator with 12.6kWp (45x280Wp) and a GEKO diesel generator with remote start electronic as backup power source were supplied. The installation and commissioning of the system was carried out by a local electrician.
