Maintenance and Cleaning

Once the output power is derating because of too high warming, some tips can help
you solve such problems:
The air grills are clogged. To clean the air grills or heat sink.
Ventilation of installation location is poor. Choose appropriate installation
location before mounting.
8.1 Cleaning the Inverter
If the inverter is dirty, turn-off the AC breaker and DC switch, waiting the inverter
shut down, then clean the enclosure lid and the display using only a wet cloth. Do not
use any cleaning agents (e.g. solvents or abrasives).
8.2 Checking the DC Disconnect
Check for externally visible damage and discoloration of the DC Disconnect and the
cables at regular intervals. If there is any visible damage to the DC Disconnect, or
visible discoloration or damage to the cables, contact the installer.
Once a year, turn the rotary switch of the DC Disconnect from the "On" position
to the "Off" position 5 times in succession. This cleans the contacts of the rotary
switch and prolongs the electrical endurance of the DC Disconnect.
