Contenuto del pacchetto:

This switch is an important accessory for photovoltaic power storage battery: it allows to automatically divert the current from the batteries to the ENEL mains when batteries are down.
When the batteries will be recharged or photovoltaic group will have restored its ability to provide current, it will be hunged up automatically.
It specifies that there is not energy fed into the grid. The energy is taken when needed, in the event of battery leakage.

The switching signal is taken from the charge controller, which senses the discharge and charge the battery and attaches and detaches so the coil of the switch, resulting in the deviation of the current draw from batteries or mains Enel.
