5.3 Installing the AC Output Power Cable

Prerequisites

An AC switch must be installed on the AC side of the SUN2000 to ensure that the SUN2000 can be safely disconnected from the power grid.

Do not connect any load between the SUN2000 and the AC switch.

Context

The SUN2000 can detect the grounding. This function is used to detect whether the SUN2000 is properly grounded before starting it, or to detect whether the PE cable is disconnected when the SUN2000 is working. This function is available only under limited conditions. To ensure the safe operation of the SUN2000, properly ground the SUN2000 in strict accordance with the connection requirements for PE cables. For certain types of power grids, if an isolation transformer connects to the output side of the SUN2000, you need to set Grounding inspection to Disable after checking that the SUN2000 is properly grounded. Then the SUN2000 can start normally. If you are not sure whether the SUN2000 connects to such a power grid, confirm it with your supplier or Huawei technical support.

Procedure

Step 1 Connect the AC output power cable to the AC connector.



According to IEC62109, to ensure the safe operation of the SUN2000 in the case of PE cable damage or disconnection, connect the SUN2000 PE cable according to the requirements described in

5.2 Installing the PE Cable and ensure that the SUN2000 PE cable meets at least one of the

following requirements before disabling the grounding detection function. The SUN2000 PE cable is a copper cable with a cross-sectional area of at least 10 mm2. Use two cables that have the same diameter as the AC output power cable to ground the PE terminal

on the AC connector and the ground screw on the enclosure respectively (see 5.2 Installing the PE

Cable and 5.3 Installing the AC Output Power Cable for details).



Certain countries require an additional PE cable for the SUN2000. In this case, use two cables that have the same diameter as the AC output power cable to ground the PE terminal on the AC connector and the ground screw on the enclosure respectively (see 5.2 Installing the PE Cable and

5.3 Installing the AC Output Power Cable for details).



Ensure that the cable jacket is inside the connector.



Ensure that the exposed core wire is totally inserted into the cable hole.



Ensure that AC terminations provide firm and solid electrical connections. Failing to do so may cause SUN2000 malfunction and damage to its AC connectors.



Ensure that the cable is not twisted.

5.4 Installing the DC Input Power Cable

Prerequisites



Before connecting the DC input power cable, ensure that the DC voltage is within the safe range (lower than 60 V DC) and that the DC switch on the SUN2000 is OFF. Failing to do so may result in electric shocks.



When the SUN2000 is operating, it is not allowed to work on DC circuit, such as connecting or disconnecting a PV string or a PV module in a PV string. Failing to do so may cause electric shocks.



If no PV string connects to the DC input terminals, do not remove the watertight cap from the DC input terminals. Otherwise, the SUN2000 will not comply with its Ingress Protection Rating.

Ensure that the following conditions are met. Otherwise, the SUN2000 will be damaged, or even become a fire hazard.

The open-circuit voltage of each PV string is always lower than or equal to 600 V DC.



The positive and negative terminals of a PV string connect to corresponding positive and negative DC input terminals of the SUN2000.



If polarity of the DC input power cable is reversed and the DC switch is ON, do not turn off the DC switch immediately or unplug positive and negative connectors. Wait until the solar irradiance declines at night and the PV string current reduces to below 0.5 A, and then turn off the DC switch and remove the positive and negative connectors. Correct the string polarity before reconnecting the string to the SUN2000.



The PV terminal of the inverter supports only the PV string input and cannot be connected to other power supplies. Since the output of the PV string connected to the SUN2000 cannot be grounded, ensure that the PV module output is well insulated to ground.



During the installation of PV strings and SUN2000, the positive or negative terminals of PV strings may be grounded if power cables are not properly installed or routed. In this case, an AC or DC short circuit may occur and damage the SUN2000. This damage is not covered under any warranty.

High String Input Voltage

Major

The PV array is incorrectly configured. Excessive PV modules are connected in series to the PV string, and therefore the open-circuit voltage exceeds the maximum inverter input voltage.

Reduce the number of PV modules connected in series to the PV string until the PV string open-circuit voltage is less than or equal to the maximum inverter input voltage. After the PV array is correctly configured, the inverter alarm disappears.

The following is the mapping between PV strings and alarm cause IDs:



Cause ID = 1: string 1



Cause ID = 2: string 2

7.2 Troubleshooting

Alarm severities are defined as follows:



Major: The SUN2000 enters Shutdown mode and disconnects from the power grid to stop generating power after a fault occurs.



Minor: Some components are faulty but the SUN2000 can still connect to the power grid and generate power.



Warning: The SUN2000 output power decreases due to external factors.

contact your dealer.

2051

Abnormal Residual Current

Major

Cause ID = 1 The insulation

impedance of the input side to PE decreases when the SUN2000 is operating.

1. If the alarm occurs accidentally,

the external power cable may be abnormal temporarily. The SUN2000 automatically recovers after the fault is rectified.

2. If the alarm occurs frequently or

persists, check that the impedance between the PV string and ground is not below the lower threshold.

2061

Abnormal Grounding

Major

Cause ID = 1



The protective earthing (PE) cable for the SUN2000 is not connected.



The voltage between the SUN2000 neutral wire and ground exceeds the upper threshold.

1. Check that the PE cable for the

SUN2000 is connected properly.

2. If the SUN2000 is connected to

the TN power grid, check whether the voltage of the neutral wire to ground is normal.

3. Check whether the output is

connected to an isolation transformer. If so, set Grounding inspection to Disable.
