GB/T 37663.3-2019 is the Chinese standard "Outdoor empirical test requirements for distributed photovoltaic in warm damp climate—Part 3: Grid-connection photovoltaic system".
Its scope clause reads: This part of GB/T 37663 specifies the outdoor empirical test requirements for distributed grid-connected photovoltaic systems, including the basic requirements for empirical testing.
Seeking and testing methods for solar energy empirical tests, empirical tests for power generation efficiency, empirical tests for power generation operations, and empirical tests for grid-connected performance.
This section applies to the "damp heat" climate zone specified in GB/T 4797.1, which is connected to the grid through the AC380V voltage level, and The AC10(6)kV voltage level is connected to the user side to build, rebuild and expand the distributed grid-connected photovoltaic system.
It is not applicable to the concentrating photovoltaic module group. A distributed grid-connected photovoltaic system. Large-scale ground-based photovoltaic power plants, as well as grid-connected photovoltaic systems in the “sub-humid tropics” climate zone, can also refer to carried out. Its clauses include terms and definitions.
