11 Maintenance and Cleaning
11.1
Checking Heat Dissipation
If the inverter regularly reduces its output power due to high temperature, please improve the
heat dissipation condition. Maybe you need to clean the heat sink.
11.2
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, the display, and the LEDs using only a wet cloth. Do not use
any cleaning agents (e.g. solvents or abrasives).
11.3
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.

2.
Make sure the cable polarity is correct and voltage is less than 1100V
3.Switch on the build-in DC isolator at the bottom of the inverter.
4.Switch on the PV Array and DC isolator next to your inverter, if you can not find this
switch, skip this step.
5.Switch on the Solar AC isolator if the inverter is more than 3 meters away from your switch-
board.
6.Switch on the solar supply main switch in the switch board.
12.2
Shut down the inverter
Danger
