Three phase full backup system near Weilheim with Axitec PERC half cell modules, a 7.7kWh BYD battery and Fronius Gen24 6.0 plus hybrid inverter. The full backup system was realized identical to the enwitec backup box with relay controlled full phase disconnection with 2 series contactors, PEN connection with 2 parallel contactors and a 300mA selective RCD + 16A fuse. Successful system check in the end and lots of paperwork done for the registration/commissioning/documentation. Yay!
