Electrical Connection

Connection to the grid (AC side connection)

1. When connecting the inverter make sure to adjust the voltage and the frequency in compliance with the grid regulations and the specifications of the manufacturer.
2. Add a breaker or fuse to the AC side. Please note that the specification should be more than 1.25 times of rated AC output current.
3. The PE line of the inverter should be connected to the earth. Make sure the impedance of neutral wire and earth wire is less than 10ohm.
4. Disconnect the breaker or fuse between the inverter and the utility.
5. Please note that there are two AC connector brands compatible with the GoodWe inverters: VACONN and WIELAND. Choose one of them to connect the inverter to the grid.
6. When laying the AC line make sure that the protective earthing conductor is not strained.

AC circuit breaker and leakage current protection device

Please install an independent two-pole circuit breaker to protect the inverter and make sure it is safe to disconnect it from the grid. In addition to the built-in RCMU, an external RCD is required to ensure that the inverter system does not carry DC residual currents. To avoid tripping, types A or B can be used.

Note: it is not recommended that multiple inverters share a single circuit breaker.

DC Side Connection

1. Before connecting the PV strings, please ensure the plug connectors have the correct polarity. Incorrect polarity has the potential to cause permanent damage to the unit.
2. The open-circuit voltage of the PV strings cannot exceed the maximum input voltage of the inverter.
3. Only the GoodWe supplied DC connectors are suitable for use.
4. The positive and negative pole should not be connected to the PE wire (ground wire). Not following this instruction may cause damage to the inverter.
5. Do not connect the positive or negative poles of the PV string to the PE wire. Not following this instruction may cause damage to the inverter.
6. Red represents positive, black represents negative.
7. For the XS series, the minimum insulation resistance to the ground of the PV panels must exceed 16.7kΩ (R=500/30mA).  There is risk of shock hazard if this minimum resistance requirement is not met.

Wi-Fi Communication

The Wi-Fi communication function is only available with Wi-Fi BOX. For detailed configuration instructions please refer to the Wi-Fi Configuration on the accessory box. Once configuration is completed, please browse the monitoring portal website to set up PV stations on the system.

Earth Fault Alarm

In compliance with section 13.9 of IEC62109-2, the GoodWe XS inverter is equipped with an earth fault alarm. When earth fault occurs, the fault indicator at the front LED screen will light up. On inverters with Wi-Fi communication, the system sends an email with the fault notification to the customer. For inverters without Wi-Fi, the buzzer of the inverter will keep ringing for one minute and ring again after half an hour until the fault is resolved. (This function is only available in Australia and New Zealand).

Auto-Test

Short press the key 2S to enable the Auto Test Function. There are two types of Auto Test, Remote and Local. The Remote type default is 1 and cannot be modified. The Local default is 0 and can be set from 0 to 1. If the Auto Test is set to 1, the testing order will be 59.S1, 59.S2, 27.S1, 81>S2, 81<S2. Otherwise, the testing order would be: 59.S1, 59.S2, 27.S1, 81>S2, 81<S2. When the AC is connected, the AutoTest will start to run once the inverter relay has been completed: the output power is equal to zero and the test information will be indicated on the LCD screen.
If the test is passed, the inverter automatically gets reconnected to the grid in accordance with CEI 0-21 requirement. The next test then gets started. If the test is not passed, the inverter enters wait mode. To try again, the user will need to power off the inverter and reboot it. For future reference, all previous tests records get stored: to access the information, short press the key Autotest Result on the Menu, then long-press the key 2S to view previous tests reports.
