The Domestic Firefighter safety Switch

In most photovoltaic systems, the DC isolator is integrated into the DC/AC power inverter. After switching off the DC isolator, the cables between the DC solar modules and DC/AC power inverter running through the building are still subject to up to 1000 V DC. In the event of a fire, firefighters are exposed to a very serious source of potential danger.

The Santon domestic firefighter safety switch (DFS) provides the solution. It directly disconnects the DC current in close proximity to the solar modules and creates a safer situation for firefighters.
