Do Huawei inverters meet UL 1699b-2018 arc fault circuit protection requirements?

To verify the performance and availability of arc-fault circuit interrupter (AFCI), Huawei entrusted the China General Certification Center (CGC) to complete comprehensive evaluation, with its results showing that Huawei inverters with the AFCI function meet the requirements of UL 1699B-2018 "Safety Standard for PV DC Arc Fault Circuit Protection."

What is DC arc fault circuit protection?

DC arc-fault circuit protection provides supplementary protection against fires that may arise as a result of arcing faults in PV system components or wiring. SMA Sunny Boy US inverters are now available with integrated Arc Fault Circuit Interrupter (AFCI) functionality.

Do PV systems need arc-fault circuit protection?

These requirements apply to newly installed PV systems with a maximum voltage of 80 volts or greater. Such PV systems must be equipped with direct current (DC) arc-fault circuit protection. DC arc-fault circuit protection provides supplementary protection against fires that may arise as a result of arcing faults in PV system components or wiring.

How to control a PV inverter?

The control algorithm starts by simultaneous measurement of five sensors that determine the status of the PV inverter: I P V, V P V, I B, V B, V D C − l i n k, V g r i d and I g r i d. The MPPT parameters generate the references for the duty cycle D of the boost converter.

What is predictive control in PV inverter?

The proposed model predictive control keeps the DC-link stable in pre-fault, fault, and post fault modes. The PV inverter will not trigger the over-voltage or the over-current protection due to grid voltage sags, thus fulfilling the grid code requirement. 3.3. Comparison with other LVRT strategies
