Chapter 6 Maintenance
6.1 Operation environment requirements
Temperature: -20~60
℃
Humidity: 0~95% (non-condensing)
Max. elevation: 4,000m
It is recommended that the operating temperature should be
maintained between -20~45
℃
so as to ensure the best performance
of the convert. If the temperature is too high or low, it will shorten the
service life of inverter.
If the altitude exceeds 2,000 meters, the energy storage inverter will
de-rate.
6.2 Electrical and fixed connection inspection
After installation and commissioning, routine inspection on follow items is recommended
every three months. Record for each inspection should be made.
All-in-one grounding connection;
Electrical connection for DC input;
Electrical connection for AC input;
Connection for communication cables;
AC/DC switches and fans;
Read monitoring fault information.
6.3 Clearing and cleaning
Before installation and commissioning, regularly clean the dust and sundries in the
terminals and mesh openings of the inverter.
After installation and commissioning, regularly clean the dust in machine room, check
ventilation and air exhaust facilities. Cleaning once every three months is recommended.
After installation and commissioning, regularly clean dust in inverter fan and insect
prevention mask. Cleaning once every three months is recommended.
CAUTION
The dust on the fan can block the ventilation duct, and the inverter
shuts down due to over-temperature, which will severely affect the
normal operation of the inverter.
