Solar Power System Fire Protection Solutions

Causes of Fire

Due to their outdoor operating environment and the use of high-voltage DC power, solar power system is highly vulnerable to rapid fire propagation once ignition occurs.

Connector Contact Failure

Long-term outdoor exposure can cause deformation, loosening, increased contact resistance, and localized overheating of MC4 connectors, leading to ignition.

Combiner Box and Inverter Short Circuits

Aging components and arc faults within combiner boxes, inverters, and other electrical panels carrying continuous high-voltage power can result in fire incidents.

Outdoor Cable Degradation

UV radiation, moisture, and environmental changes can damage cable insulation, increasing the risk of ground faults, short circuits, and cable fires.

Safety Compliance & Value

SFEXTECH's solutions are preventive fire protection systems designed to suppress fires at critical ignition points within solar power installations, including connectors, combiner boxes, and cable routes. These solutions contribute to improved electrical safety compliance and support the implementation of proactive safety and health management systems.

SFEXTECH Solutions

SFEXTECH protects solar power system exposed to outdoor environments by integrating cover-, rope-, and tape-type solutions tailored to the specific ignition points of critical components.

Fire Suppression and Protection for MC4 Connectors with SFEX MC4 Cover

SFEX MC4 Cover is an automatic fire extinguishing cover designed to completely enclose and protect MC4 connectors.

Made of UL94 V-0 rated flame-retardant EPDM material, it offers excellent weather resistance, heat resistance, and electrical insulation, while protecting connectors from external physical impact.

In the event of a fire, the integrated fire suppression sheet provides combined cooling and smothering effects, effectively suppressing the fire at the earliest stage.

Automatic Fire Suppression Inside Combiner Boxes and Inverters with SFEX Line

SFEX Line is a rope-type automatic fire extinguisher for medium- and large-scale distribution panels, combiner boxes, and inverters.

Its flexible rope-type design allows installation in close proximity to potential ignition points within complex equipment configurations.

Operating independently without external power, it eliminates the risk of system malfunction and suppresses fires through the catalytic inhibition effect of a nitrate-based condensed aerosol extinguishing compound.

Prevention of Fire Propagation in Incoming and Outgoing Wiring with SFEX AP Tape

SFEX AP Tape is a tape type fire retardant for cables incorporating micro fire-extinguishing capsule technology that automatically releases an extinguishing agent when exposed to a predetermined temperature or flame.

Applied directly to wiring sections and incoming/outgoing cables where flame propagation can occur rapidly, it suppresses fires through a combination of cooling action and catalytic inhibition while simultaneously providing flame-retardant and electrical insulation performance.
