xFire Fighter Series PV Combiner Box with Rapid Shutdown 5 ways
DC Isolation for Rooftop Fire Safety
The BHT-5/5 Series PV Combiner Box with rapid shutdown is a DC isolation solution designed to enhance solar rooftop fire safety. It enables manual disconnection of DC power in the event of a fault, creating a safe operating area for firefighters and reducing the risk of DC electric shock.
When the AC power is shut off in the house, the safety switch simultaneously disconnects the DC power, ensuring full system shutdown and firefighter protection.
Connectivity: 5 Solar PV Input to 5 Solar PV Outputs 50Amps per string - paralleling permitted up to this current level at 1500V
Key Features
- String-Level Rapid Shutdown
- Supports up to 1500VDC, 50A per string
- Plug and Play Installation
- No Interference with Inverter or Wi-Fi

Automatic Shutdown – Over Temperature
DC power will automatically switch off when the temperature inside the BFS-S enclosure reaches or exceeds 85°C. Once the temperature drops below 75°C, the system will automatically restore DC power.
Automatic Shutdown – AC Power Loss
In the event of AC power loss, whether accidental or manually triggered by firefighters, the system will automatically shut down the DC power. Once AC power is restored, DC power will automatically return.
100% Shutdown – Emergency Button
By pressing the emergency button, DC power will remain completely off—even if AC power is restored—ensuring a 100% safe zone for emergency personnel during critical operations.
