WHY NEED LULU’S FIREFIGHTER SAFETY SWITCH?
Fatal Risk: Fighting a Fire in the House with PV System
According to the standard international safety routine, in the event of a fire, the first step for any firefighter in fighting a fire is to shut down the main AC power circuit. This makes a place for firefighter to fighting a fire without the risk of electrocution.
However, it is still danger for fighting a fire if the house has photovoltaic systems, even the firefighter find the DC isolator and shut it down manually.
Since 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. That left firefighters facing a very serious of potential electrocution danger.
THE SOLUTION OF LULU’S FIREFIGHTER SAFETY SWITCH
The LULU firefighter safety switch (LFS) provides the solution. It directly disconnects the DC current in closest to the solar panels automatically and creates a safer situation for firefighters.
1. The firefighter turn off the AC power manually
No more action needed, just like fighting the fire in the house without photovoltaic system.
2. The LFS will shut down the DC power automatically
If LFS detect no AC current more than 5 seconds, it will automatically cut off the DC current at once.
