I checked the manual. (Which you can download from the product page at victronenergy.com)

In section 3.2 there's a specific warning to not connect the battery the wrong way round, it will blow the internal fuse and may damage the inverter.

Thanks for Your answer, but the section 3.2 speak about Reverse polarity.(Reverse polarity connection of the battery wires will blow the internal fuse and can damage the inverter. The internal fuse is not always replaceble (see table above).

We wont connect in reverse polarity, we will connect the right polarity but our positive is connected to the ground.
