7 Technical description

7.1 General description

The inverter is a DC-to-AC sine wave inverter with integrated transfer switch.

The inverter can be operated in the following network systems:

• TN network
• IT network

The network systems are set via a screw on the inverter.

The inverter has the following protective mechanisms:

• Overvoltage shutdown: The inverter switches off when the voltage exceeds the cut-off value. The inverter restarts automatically when the voltage drops to the restart value.
• Undervoltage shutdown: The inverter switches off when the voltage falls below the cut-off value. The inverter restarts automatically when the voltage exceeds the restart value.
• High temperature shutdown: The inverter switches off when the internal temperature of the device exceeds the cut-off value. The inverter restarts automatically when the internal temperature drops to the restart value.
• High output current protection: The inverter switches off when too many loads are connected.
• Protection against short circuit: The inverter switches off when a short circuit has been generated. The inverter restarts automatically after a few seconds. If a short circuit is detected for five consecutive times, the inverter does not restart automatically and a manual restart is needed.

The inverter is N-BUS and CI-BUS compliant for data and function, both controllable on a touch display (accessories) and the mobile app. The inverter is equipped with a remote control for switching the inverter on or off. The inverter can be switched to the energy-saving mode in order to reduce idle consumption and minimize the load on the battery. This can be done via a DIP switch or
