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 theAC breakerand DC switch ,waiting the inverter
shut down ,then clean theenclosure lid,the display, and the LEDs usingonlyawet-
cloth. Do not use any cleaning agents (e.g. solven ts 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 clea ns the contacts of the rotary
switch and prolongs the electrical endurance of the DC Disconnect.
12.1 Start the inverter
1 .Close the inverter AC circuit breaker.
2. Close the DC switch, when the input PV voltage is higher than 250Vdc, and the
inverter will start automatically.
12.2 Shut down the inverter
Steps to turn off the inverter:
1. Disconnect the AC circuit breaker to prevent the inverter from starting again;
2. Turn off the DC switch;
3. Checktheoperatingstatusofthe inverter;
4. Wait untilthe LEDand OLED display are off, indicating that the inverter is turned
