Product Description
The BHT-5/5 Series combiner box brings string-level rapid shutdown to rooftop solar arrays, giving firefighters a safe way to isolate DC power in an emergency. It takes 5 solar PV string inputs and outputs, rated at 50A per string at 1500V DC, and cuts DC power across all strings the moment AC supply is removed from the property.
This DC isolation function reduces the risk of electric shock on the roof during a fire or fault and helps installations meet rapid shutdown requirements for rooftop fire safety.
Key features of this solar panel rapid shutdown device
- String inputs, 5 solar PV strings, 50A per string
- Voltage rating, 1500V DC
- Automatic shutdown, disconnects all DC strings simultaneously when AC power is removed
- Thermal protection, automatic shutdown on over-temperature inside the BFS-S enclosure
- Installation, plug and play, does not interfere with inverter operation or Wi-Fi
- Compatibility, works with most string inverters and solar panels
Applications
Fitted on residential and commercial rooftop solar PV systems where fire safety rapid shutdown compliance is needed, and wherever firefighters require DC isolation access at roof level.
Installation notes
Install according to the manufacturer's wiring guide and current electrical regulations. Position the rapid shutdown device so it is accessible to firefighters. DC connections should only be made by a qualified solar installer.
