----End Before connecting the DC input power cables, 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 running, it is not allowed to work on the DC input power cables, 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 a DC input terminal of the SUN2000, do not remove the watertight cap from the DC input terminals. Otherwise, the IP rating of the SUN2000 will be affected. Ensure that the following conditions are met. Otherwise, the SUN2000 may be damaged, or even a fire may occur. Issue 01 (2021-04-05) Copyright Huawei Technologies Co., Ltd. 52 Replacing SUN2000-(15KTL-50KTL) Series with SUN2000-(15KTL-50KTL)-M3 Series User Manual 6 Electrical Connections PV modules connected in series in each PV string are of the same specifications. The DC input voltage of the SUN2000 shall not exceed 1100 V DC under any circumstance. The polarities of electric connections are correct on the DC input side. The positive and negative terminals of a PV string connect to the corresponding positive and negative DC input terminals of the SUN2000, respectively. If the DC input power cables are reversely connected, do not operate the DC switch as well as positive and negative connectors immediately. 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 PV string polarity before reconnecting the PV string to the SUN2000. The SUN2000 does not support power supplies other than PV strings. 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 the SUN2000, the positive or negative terminals of PV strings may be short-circuited to ground if the power cables are not properly installed or routed. In this case, an AC or DC short circuit may occur and damage the SUN2000. The caused device damage is not covered under any warranty.

The PV-MS (Staubli) or PV-MS-HZ (Staubli) open-end wrench is recommended. Cables with high rigidity, such as armored cables, are not recommended as DC input power cables, because poor contact may be caused by the bending of the cables. Before assembling DC connectors, label the cable polarities correctly to ensure correct cable connections. After the positive and negative connectors snap into place, pull the DC input power cables back to ensure that they are connected securely. Use the positive and negative Staubli MC4 metal terminals and DC connectors delivered with the SUN2000.

----End Before connecting the DC input power cables, 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 running, it is not allowed to work on the DC input power cables, 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 a DC input terminal of the SUN2000, do not remove the watertight cap from the DC input terminals. Otherwise, the IP rating of the SUN2000 will be affected. Ensure that the following conditions are met. Otherwise, the SUN2000 may be damaged, or even a fire may occur. Issue 01 (2021-04-05) Copyright Huawei Technologies Co., Ltd. 76 Replacing SUN2000-(15KTL-50KTL) Series with SUN2000-(15KTL-50KTL)-M3 Series User Manual 6 Electrical Connections PV modules connected in series in each PV string are of the same specifications. The DC input voltage of the SUN2000 shall not exceed 1100 V DC under any circumstance. The polarities of electric connections are correct on the DC input side. The positive and negative terminals of a PV string connect to the corresponding positive and negative DC input terminals of the SUN2000, respectively. If the DC input power cables are reversely connected, do not operate the DC switch as well as positive and negative connectors immediately. 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 PV string polarity before reconnecting the PV string to the SUN2000. The SUN2000 does not support power supplies other than PV strings. 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 the SUN2000, the positive or negative terminals of PV strings may be short-circuited to ground if the power cables are not properly installed or routed. In this case, an AC or DC short circuit may occur and damage the SUN2000. The caused device damage is not covered under any warranty. In the spare part replacement scenario, the DC input power cables can be connected only to PV1PV6. If the DC input power cables are connected to PV7 or PV8, the inverter data cannot be transmitted to the northbound device. Figure 6-45 DC input terminals When the DC input is not fully configured, the DC input terminals must meet the following requirements:
1. Evenly distribute the DC input power cables on the four MPPTs and preferentially connect them from MPPT 1 to MPPT 4. 2. Maximize the number of connected MPPTs.
