Does the main AC cable have to be disconnected in this case?

The AC main (grid) cable does not need to be disconnected. The system will immediately switch back to the mains when it is available again.

The following models of Charger vision are available.

The 'cable' version of our three-phase 11 kW Charger vision includes a fixed 6m long Type 2 charging cable which is permanently attached to the charger, while the 'shutter' versions include a socket to allow the customer to insert their own Type 2, Mode 3 EV Charging cable; please note there is no cable version of the single-phase 7 kW Charger vision. 

SOLARWATT does not offer a wall bracket for Battery vision.

The battery must be placed on a stable solid surface and fixed to the wall with the included wall brackets (which secure the tower to the wall, but are not load bearing). Please observe the specified clearances:
