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.
