1. Nature of the accident
   Two serious product accidents occurred with smoke emanating from power conditioners for photovoltaic systems manufactured by Omron Corporation and sold by Kyocera Corporation and were reported in accordance with the provision of Article 35, Paragraph 1 of the Consumer Product Safety Law (Control Nos. A200900363 and A201100258). Further, three similar accidents (non-fire accidents) have been reported to the National Institute of Technology and Evaluation (NITE). No deaths or injuries have resulted from these five accidents.

   It is supposed that the accidents resulted from a variation of insulation performance of film capacitors inside the products. Due to the effect of an abnormally high voltage from outside caused by thunder or the like and of ambient temperature during use, the component may have short-circuited and emanated smoke.

2. Recurrence prevention measures
   To prevent further accidents, Omron Corporation will today issue a press release, post a message on its website and directly send a notice to users, and will start free inspection and repair of the recalled products. Kyocera Corporation will also post a message on its website at the same time.
