The bidirectional battery inverter must be grounded to the earth system of the installation.
The cross-section of the copper wire must be at least the same cross-section of the connected outer conductor, and
at least 6 mm².
Please refer to local regulations for more information on the size of the ground cable.
Ground the device by connecting the protective earth conductor from a suitable location (e.g. main earthing bar) to
