In this case, the connectors may be heated and oxidized, which may cause faults. · Ensure that the locking nuts of all connectors are tightened. · Do not bind more than three fuse enclosures together. Otherwise, the fuses and their enclosures may be damaged due to overheating. It is recommended that a clearance of 10 mm or more be reserved between fuse enclosures. You are advised not to bind the fuse enclosures with other heat emitting conductors. Wiring rules: 1. The PV+ on the string side must be connected to the PV+ on the SUN2000 side, and the PV on the string side must be connected to the PV on the SUN2000 side. 2. Preferentially and evenly connect the Y-branch connectors to the MPPTs controlled by DC SWITCH 1 or DC SWITCH 2. 14 Number of Ybranch Connector Sets Recommended MPPT to Be Connected 1 MPPT1 3 MPPT1, MPPT3 and MPPT4 5 MPPT1, MPPT2, MPPT3, MPPT4, and MPPT5 7 MPPT1, MPPT2, MPPT3, MPPT4, MPPT5, MPPT6, and MPPT7 9 MPPT1, MPPT2, MPPT3, MPPT4, MPPT5, MPPT6, MPPT7, MPPT8, and MPPT9 Y-branch Connector Solution Number of Y-branch Connector Sets Recommended MPPT to Be Connected 2 MPPT1 and MPPT4 4 MPPT1, MPPT3, MPPT4 and MPPT6 6 MPPT1, MPPT2, MPPT3, MPPT4, MPPT5, and MPPT6 8 MPPT1, MPPT2, MPPT3, MPPT4, MPPT5, MPPT6, MPPT7, and MPPT8 N/A N/A 15 Scenario Model of Y-branch Connector (Part A) Connection Description Connecting Ybranch connectors to the PV strings (recommended) All models Use the DC terminals delivered with the SUN2000s to connect part B to the SUN2000s. Connecting Ybranch connectors to the SUN2000 Models recommended by Huawei Other models Part A can be directly connected to the SUN2000, and part B is not needed. To ensure that the terminals of part A match the DC terminals of the SUN2000, part B is needed to connect part A to the SUN2000. Use the DC terminals delivered with the SUN2000 to connect part B to the SUN2000. · It is recommended that the Y-branch connectors be connected from the PV string side and tied to the PV trackers. · The DC input terminals of the solar inverter are prone to damage under stress. When Ybranch connectors are connected to the solar inverter, bind and secure the connectors to minimize stress on the DC input terminals. · Do not place the Y-branch connector harness on the ground. A safe distance must be reserved between the Y-branch connector harness and the ground to avoid impact caused by water on the ground to the harness. Recommended tying solution: 16 Selecting DC Input Terminals The SUN2000 has three DC switches (DC SWITCH 1, DC SWITCH 2, and DC SWITCH 3). DC SWITCH 1 controls routes 16 of DC input terminals, DC SWITCH 2 routes 712, and DC SWITCH 3 routes 1318. Select DC input terminals according to the following rules: 1. Evenly distribute the DC input power cables to the DC input terminals controlled by the three DC switches. DC SWITCH 1 is preferred. 2. Maximize the number of connected MPPT circuits. Ensure that the PV module output is well insulated to ground. 1. Use the MC4 EVO2 PV connectors delivered with the SUN2000. If the PV connectors are lost or damaged, purchase the connectors of the same model. The device damage caused by incompatible PV connectors is beyond the warranty scope. 2. Before connecting DC input power cables, label the cable polarities to ensure correct cable connections. If the cables are connected incorrectly, the SUN2000 may be damaged. 3. Measure the voltage at the DC input end using a multimeter. If the voltage is a negative value, the DC input polarity is incorrect. Correct the polarity. If the voltage is greater than 1500 V, too many PV modules are configured to the same string. Remove some PV modules. 4. 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. The device may be damaged if you do not follow the instruction. The caused equipment damage is beyond the warranty scope. Wait until the solar irradiance declines and the PV string current reduces to below 0.5 A, and then turn off the three DC switches and remove the positive and negative connectors. Correct the string polarity before reconnecting the string to the SUN2000. 5. For models of the crimping tool and removal wrench, use the recommended model or contact your Staubli dealer. 6. Connect the PV string connector to the inverter connector, and then pull back the PV string connector along the axial direction to check whether the connectors are securely connected. 7. The connector must be securely connected. Damages caused by improper connection are not covered under the warranty. 17 Installing a DC Input Power Cable Positive metal contact Negative metal contact Click PV-CZM-41100 (STAUBLI) Ensure that the cable cannot be removed after crimped.
