    • Storage and Disposal of the product. The Benshaw model H2 series inverters are an industrial electronic product with advanced semiconductor components. A reasonable life expectancy of 8 to 10 years can be expected however, there are factors that may affect their continued long-term operation. Environmental issues (temperature and humidity) and mechanical issues (vibration and connections) are the most common reasons for premature failure of inverters.
