and damage to inverters.
Special disposal instructions • Static electricity may damage electronic components. Appropriate method must be adopted to
prevent such damage to the inverter; otherwise the inverter may be damaged and the warranty
will be annulled.

Fragile • Ensure the output voltage of the proposed PV array is lower than the maximum rated input
voltage of the inverter; otherwise the inverter may be damaged and the warranty will be
annulled.

Keep Dry • When exposed to sunlight, the PV array will generate very high voltage which will cause potential
danger to people. Please strictly follow the instruction we have provided.

• PV modules should have an IEC61730 class A rating.

Refer to operation instructions • If the equipment is used in a manner not specified by the GOODWE, the protection provided by
the equipment's design may be impaired.

• To completely isolate the equipment : switch off the DC switch, disconnect the DC terminal, and

remove the fans.

1. Disconnect the AC breaker first and then disconnect DC breaker.

2. Wait 5 minutes until the residual voltage has been released and the fans are no longer running.

3. Disassemble the fans (Refer to the below figure).

• Loosen the five screws with a crosshead screwdriver, then remove the fans out of the cabinet
about 50mm slowly.

• Open the lockers of the three fans connectors and remove them from housing, then take the
fans away.

4. Clean the ventilation grid and the fan with soft brush, paint brush, or compressed air.

5. Reassemble the fans into the cabinet.

6. Please use towel to clean the heat-sink once a year.

8.2 Checking The DC Switch

DC switch does not require any maintenance

Though unnecessary, maintenance as below is still recommended:

• Check the DC switch regularly.

• Activate the DC switch 10 times in a row once a year.

Operating the switch will clean the switch and will extend the life of the DC switch.

Boot order:

1. Turn on the breaker on AC side.

2. Turn on the DC switch.

3. Turn on the breaker on DC side.

Note: If there's no switch, only need to do step 1 and step 3(please skip step 2).

Shutdown order:

1. Turn off the breaker on AC side.

2. Turn off the DC switch.

3. Turn off the breaker on DC side.

Note: If there's no switch, only need to do step 1 and step 3(please skip step 2).

8.3 Checking The Electrical Connection

1. Check if the AC or DC wire is loose.

2. Check if the earth wire is reliably grounded.

3. Check if the waterproof covers of RS485 and USB port are fasten.

Note: Maintenance cycle is once every half a year.
