Photovoltaic direct-driven appliance controllers - Part 1: General requirement

Apstrakt

IEC 63349-1:2025 establishes control functions and operational performance requirements for photovoltaic direct-driven appliance (PVDDA) controllers.
PVDDA controllers are devices used for controlling power among power sources (such as a PV array, grid, energy storage, etc.) and appliances (such as an air-conditioner, refrigerator, water pump, etc.).
The requirements for PVDDA controllers are applicable to systems with voltages not higher than 1 500V DC or 1 000V AC. Safety and EMC requirements for the PVDDA controllers are under consideration and not covered by this document. Safety requirements for power converters connected to a PVDDA controller are listed as follows:
- for converter connected to PV array, IEC 62109‑1 and IEC 62109‑2 are applicable;
- for bi-directional converter connected to grid, IEC 62909‑1 and IEC 62909‑2 are applicable;
- for converter connected to energy storage, IEC 62477‑1 and IEC 62509 are applicable;
- for variable frequency drive, IEC 61800-5-1 is applicable.
Performance requirements for each individual power converter connected to a PVDDA controller refer to IEC 62093.
