1 Scope
This Standard specifies the terms and definitions, product classification, technical
requirements, test methods, inspection rules and marking, packaging, transportation and
storage for grid-connected PV inverters.
This Standard applies to grid-connected PV inverters – hereinafter referred to as
inverters – whose AC output terminal voltage does not exceed 0.4 kV.
Note: According to the Technical rules for photovoltaic power station connected to
power grid formulated by the State Grid Corporation of China, considering the
technical requirements of power transmission and distribution capacity and
power quality of power grids of different voltage levels, photovoltaic power
stations can be divided into small, medium or large photovoltaic power stations
according to the voltage level of photovoltaic power stations connected to.
Small photovoltaic power station – photovoltaic power station connected to
low-voltage power grid with a voltage level of 0.4 kV.
Medium photovoltaic power station – photovoltaic power station connected to
power grid with a voltage level of 10 kV ~ 35 kV.
Large photovoltaic power station – photovoltaic power station connected to
power grid with a voltage level of 66 kV or above.
