September 4, 2026 — A Franklin Wireless T10 cellular device experienced a severe battery rupture within an Enphase IQ Combiner box on August 14, 2026, due to a thermal runaway event, creating an immediate fire and chemical hazard.
Product Details
Incident Overview
On August 14, 2026, an incident was reported detailing a hardware failure occurring inside an Enphase IQ Combiner box. The report specifically indicates that the battery of a Franklin Wireless T10 cellular device, integrated within the combiner box, experienced severe swelling and subsequently ruptured. This event is attributed to a thermal runaway, a condition where an increase in temperature changes the conditions in a way that causes a further increase in temperature, often leading to fire or explosion. The rupture of the battery has created an immediate and serious risk of fire and chemical exposure. The precise circumstances leading to the thermal runaway and hardware failure are still under investigation, but the outcome presents a clear danger to the product’s surroundings and users.
Safety Concerns
The incident involving the Franklin Wireless T10 battery within the Enphase IQ Combiner box presents a range of critical safety concerns:
- Immediate Fire Hazard: Thermal runaway events in lithium-ion batteries can quickly escalate, leading to intense fires. The presence of flammable materials within or near the combiner box could exacerbate this risk, potentially causing significant property damage or even spreading to the structure where the solar system is installed.
- Chemical Hazard: A ruptured battery releases hazardous chemicals and fumes. These substances can be corrosive, irritant, or toxic upon contact or inhalation, posing risks of chemical burns, respiratory issues, and other health problems to anyone nearby, including residents, maintenance personnel, or emergency responders.
- Explosion Risk: While not explicitly stated as an explosion, severe swelling and rupture due to thermal runaway carry an inherent risk of explosive force, which could eject battery components or housing fragments, causing injury.
- Electrical Hazards: Any hardware failure within a solar energy system component can introduce unpredictable electrical hazards, including short circuits or arcing, which further contribute to fire risk or potential electrocution.
- Property Damage Potential: Beyond the immediate unit, a fire originating from the combiner box could cause extensive damage to the solar array, the building structure, and surrounding property.
- Who Might Be Affected: Homeowners and commercial property owners with solar installations utilizing an Enphase IQ Combiner box that contains a Franklin Wireless T10 cellular device are directly at risk. Installers and maintenance technicians who interact with these systems could also be exposed to hazards if they are unaware of the potential for such failures.
What Consumers Should Do
If you own an Enphase IQ Combiner box that integrates a Franklin Wireless T10 cellular device, it is crucial to take the following actions:
- Do NOT Attempt to Repair or Open: Under no circumstances should you attempt to open, inspect, or repair the Enphase IQ Combiner box or the Franklin Wireless T10 device yourself, especially if you suspect battery swelling or notice any unusual odors, heat, or smoke.
- Immediate Disconnection (If Safe): If you can safely access your solar system’s main disconnect switch without approaching the combiner box itself, consider turning off the system. However, if there are any signs of fire, smoke, or extreme heat from the combiner box, prioritize your safety and evacuate, then contact emergency services immediately.
- Visually Inspect (From a Safe Distance): From a safe distance, carefully observe your Enphase IQ Combiner box for any visual signs of damage, swelling, bulging, discoloration, or unusual odors. Do not touch the unit.
- Contact Your Solar Installer/Service Provider: Reach out to the company that installed your solar system or your designated solar service provider. Inform them of this incident report and request an immediate professional inspection of your system, specifically focusing on the Enphase IQ Combiner box and any integrated cellular devices.
- Report the Incident: If you experience any similar issues or discover a faulty Franklin Wireless T10 battery or Enphase IQ Combiner box, please report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov.
- Stay Informed: Monitor official communications from Enphase Energy or Franklin Wireless regarding this issue.
