How it works and how to install it
The switch constantly monitors the availability of energy from panels and batteries. When the photovoltaic system does not produce enough energy or the batteries are discharged, it automatically transfers the power supply to the public electricity grid. Installation is done on a standard DIN rail in the electrical panel, with connection to the two energy sources and to consumers. The automatic-manual function is adjusted via the front button. Installation must be carried out by a licensed electrician according to the manufacturer's instructions.
