scope:

This Japanese Industrial Standard specifies the performance evaluation and test methods for stand-alone power conditioners of constant AC output voltage and constant output frequency, stand-alone power conditioners of constant DC output voltage, and the utility-connected power conditioners among the power conditioners for photovoltaic power generating system (hereafter referred to as PCS) complying with a) and b) below. However, AC module is excluded.

a) Rated output : ≥10 W, <100 W

1) DC input and output voltage : ≥30 V, ≤750 V

2) AC output voltage : ≥30 V, ≤600 V

b) Rated output : ≥100 W, <50 kW

1) DC input and output voltage : ≤750 V

2) AC output voltage : ≤600 V

In this Standard, a PCS to which an accumulator device is connected refers only to those which is connected to the accumulator device on the input side. Among the components of utility-connected PCS, the utility interaction protective function and utility interaction protective device such as an islanding operation detection device are excluded. A utility-connected PCS includes those having isolated operation function.

For the component equipment combined with PCSs such as an accumulator device and various interfaces, refer to the respective individual standards.
