To connect the PV strings to the GOODWE W15K-ET Hybrid Inverter, follow these steps:
1. Ensure that the component frames and the bracket system are securely grounded.
2. Connect the DC cables using the delivered PV connectors. It is important to use the provided connectors as using other connectors may cause equipment damage.
3. Make sure the DC cables are connected tightly, securely, and correctly. Improper wiring may result in poor contacts or high impedances, which can damage the inverter.
4. Measure the DC cable using a multimeter to avoid reverse polarity connection. Additionally, ensure that the voltage is within the maximum DC input voltage specified. Reverse connection and extremely high voltage can cause damage that is not covered under warranty.
5. Before connecting the PV string to the inverter, ensure that the minimum insulation resistance of the PV string to the ground meets the minimum insulation resistance requirements. The formula for calculating the minimum insulation resistance is R=Max. Input Voltage (V)/30mA.
6. The PV modules used with the inverter must have an IEC61730 class A rating.
Please note that these instructions are a summary and it is important to refer to the complete installation guide and user manual for detailed instructions and safety precautions.
