NDS Priority Switch allows the use of the inverter and batteries only when it is necessary. It is a management system of the 230V supply, useful when the system has two power sources: electrical network and an inverter connected to the battery.
By connecting the two power sources to the input of the PRIORITY SWITCH, the external main will always have the priority. There are two outputs, the first one to connect all loads to be used only when the main network is present, such as air conditioners, refrigerators and other big loads; the second output is dedicated to all the accessories that can be powered either by the inverter than from the main, for example, the 230V sockets of the vehicle.
Inverter Maximum Power: 3000W, Self-Consumption: 30mA only grid.
