Inverter changeover switch

This automatic switching station protects your inverter from power surges from an external 230 volt power source. It automatically switches your on-board voltage between the inverter (which runs on the battery) and the external power connection. Never manually switch cables again, with the risk of electric shocks, sparks or damage to the inverter. When the 'power grid' or 'shore power' fails, this device automatically switches to the battery-inverter.

Robust, simple and reliable

This inverter switching unit has a strong plastic housing with sturdy input connections for the cables. It is equipped with two robust relays, equipped with extra heavy switching contacts. This device has no advanced features or difficult software settings. It works very reliably and is easy to connect.

Also for battery with solar panels

With the availability of both power grid and inverter, the switching unit will now automatically choose the power supply of your choice:

Variant 1: Save the battery when grid power is available. This saves the battery when you have access to grid power (harbor, camping or other situations).

Variant 2: Use the battery until it is empty and then automatically switch to grid power. This setting is intended for batteries with a solar panel charging system, where you use as much free power as possible.

Connecting with terminal connections

The inverter switching unit contains 3 screw terminals for the 230 volt connections. In addition, there is a terminal block for connecting the earth wires of the cables. All connections are clearly marked and easily accessible; see photo. The manual contains connection diagrams.
