Huawei inverters support L4 intelligent arc protection, and the maximum arc detection range is 80...

The exact extract states: “Huawei inverters support L4 intelligent arc protection, and the maximum arc detection range is 80 m.” The correct answer is False because the wording makes 80 m sound like Huawei’s absolute maximum arc-detection range. In Huawei AFCI positioning, L4 intelligent arc protection refers to advanced arc detection capability, fast shutdown response, and higher detection reliability. Huawei’s AFCI white paper states that Huawei inverter AFCI performance reached the L4 level for detection scope, detection precision, and shutdown response time, but the later Huawei C & I safety positioning does not treat 80 m as the final maximum range for all scenarios. Huawei C & I materials show the arc-detection range evolving beyond 80 m for larger rooftop and commercial applications. Therefore, the statement is technically too restrictive: Huawei supports L4 intelligent arc protection, but “maximum arc detection range is 80 m” is not valid as a general Huawei capability statement.
