SKS/SISOH will automatically switch to the OFF position. Since the SKS/SISOH is located close to the PV modules, the high voltage DC current from the
PV modules will be completely isolated, which leaves a safe situation for the firefighters when fighting a fire in the commercial or residential building.

Applications and Markets

As soon as a firefighter shuts down the main AC circuit, the SKS/SISOH will detect this. If this power down situation lasts longer than 5 seconds, the SKS/SISOH will automatically switch to the OFF position. Since the SKS/SISOH is located close to the PV modules, the high voltage DC current from the PV modules will be completely isolated, which leaves a safe situation for the firefighters when fighting a fire in the commercial or residential building.
