Huawei photovoltaic inverter parameter configuration
Full configuration scenario: For a single-phase solar inverter, the number of PV modules connected in series in a PV string cannot exceed 25 and the maximum power of a PV
Issue 03 (2021-09-30) Copyright © Huawei Technologies Co., Ltd. The inverter is integrated with a comprehensive residual current detection unit to distinguish fault current from residual current. Upon detecting that the residual current exceeds the threshold, the inverter immediately disconnects from the power grid.
For other countries or regions, Huawei does not provide quality assurance. Network Application The inverter applies to grid-tied PV systems for commercial rooftop PV plants and large PV plants. The SUN2000 can also apply to the AC power system with the neutral point grounding of the step-up transformer.
The standards of certain countries and regions require that the inverter needs to be protected when the phase angle offset of the power grid three phases exceeds a certain value. Specifies the 10-minute overvoltage protection threshold. Specifies the 10-minute overvoltage protection duration.
