This component allows to cut the power supply between the converter and the hydrogenerator when this one is fastened as the POD version (under the hull).
Indeed, on this kind of installation, the hydrogenerator cannot be lifted up. The relay allows to stop the power supply when the batteries are loaded. The hydrogenerator would then turn slowly, in silence.
