9 Maintenance and Cleaning
1. Connect the AC breaker of the inverter.
2.Turn on the dc switch, and the inverter will start automatically when the input voltage
is higher than 70 V.

Start-Up the inverter
8.2
Turn-off the Inverter
9.1 Checking Heat Dissipation
9.2 Cleaning the Inverter
9.3 Checking the DC Disconnect
Turn-off the inverter step:
1.Disconect the line circuit breaker from single-phases grid and prevent it from being
reactivated.
2.Turn off the dc switch.
3.Check the inverter operating status.
4.Waiting until LED, OLED have go out, the inverter is shut down.
Do not disconnect the DC connectors under load.
DANGER
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.
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).
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.
Ø
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.
