8.1.3 Daily maintenance
Operational lifespan of inverter electronic components are closely related to
using environment, using condition and maintenance situation. Lifespan of vulnerable
parts under normal using conditions are as shown in Table 8-2:
Table 8-2 Replacement time of inverter components
Component name Lifespan
Cooling fan 2~3 years
Capacitor 4~5 years
PCB 5~8 years
Regular service conditions of above inverter components are:
1. Ambient temperature
:
annual average 30
℃。
2. Load factor
:
under 80%
3. Run time
:
below 12 hour/day
Users determine replacement period according to actual situation.
8.1.4 Storage
1. Store inverters in well-ventilated places, and avoid high temperature,
humidity and dustiness.
2. Long time storage will lead to deterioration of electrolytic capacitors. So
ensure connection the inverter to power supply at least once in two years. And
input voltage slowly raises rated value by the voltage regulator.
