WATTSTUNDE® NVS Changeover Station 16 A Mains Priority Switch
WATTSTUNDE® WS16ANVS Mains Priority Switch – Automatic Transfer Switch for Inverters & Shore Power
The WATTSTUNDE® WS16ANVS Mains Priority Switch enables the safe operation of an inverter and a 230 V AC grid within the same electrical circuit. It automatically switches between power sources and reliably protects the inverter from external voltage.
Automatic Switching with Protection Function
As soon as external 230 V AC power is present, the WS16ANVS automatically switches to this source. If the grid is disconnected, the inverter takes over the supply again.
Freely Selectable Priority via Wiring
You can determine which power source has priority – inverter or external grid – through self-selected wiring.
