Fire protection

How does it work?

All BlackMagic optimisers come with a built-in first level of fire protection as a standard: the DC circuit will automatically section individual PV panles when excessively high temperatures (85ºC+-5ºC) are detected. The panels are reconnected only once the system has been completely de-energised and re-energised: the next day or after authorised personnel carry out a manual restart.

The AF series may also be wired to a firefighter switch to be placed at the entrance of the building.  In this case, the complete system up to the panel level will only be connected when an auxiliary power line is suplying the firefighter siwtch.  When the switch is operated, the suxiliary supply si cut off, forcing the circuit open at paenl level. This system operates without the use of any “closed protocols” and electronic controls to ensure the highest possible level of responsiveness and compatibility with third-party equipment.

As each individual panel is disconnected using this feature, firefighters may operate without any risk of getting in contact with direct current.
