Environment effections such as ambient temperature, humidity, fog ,internal component aging and other factors will give rise to the occurrence
of potential faults. Therefore, it is necessary to conduct daily check and routine maintenance to the inverters.

To make the inverter work normally for long time, periodical care and maintenance for inverter’s internal electronic
component should be done. The electronic component’s lifetime depends largely on their application environment and
preservation. Normally, lifetime is:
