About Japanese photovoltaic inverter standards

This certification service is a voluntary scheme operated by JET. The objectives of this scheme are to ascertain the reliability and the safety of Photovoltaic (PV) modules and to promote wide application and usage of PV systems in the field and thus to serve to end users.

Low-voltage grid connected inverters (Power conditioners) JET’s certification system is the system to carry out product testing to ensure conformity to JET’s certification testing standard prepared based on the Grid-interconnection Technical Requirement Guidelines (currently the Grid-interconnection Technical Requirement Guidelines on .

・Construction/safety requirements of PV system: IEC TS 62548 (Enacted), IEC60363-9-1(CDV) is being examined in TC64. ・Cables: 20/1441/NP (Electric cables for Photovoltaic system) is being examined in TC20 ・Connectors: No standard. There is some movement intending to bring EN standard (EN 50521) to fast track.

However, the power generation cost of photovoltaics in Japan is about 1.6 times higher than that of the world’s weighted average in 2017, and further promotion and spread of photovoltaics requires a reduction of the power generation cost. We have newly developed and commercialized the KPV-A and KPW-A series of outdoor single phase solar .

According to the revision of the Low-Voltage Grid Interconnection Regulations in April 2024 in Japan, three-phase PV inverters used in low-voltage interconnection projects (including deemed low-voltage interconnection) must be compatible with the new active method “frequency feedback method with step injection (STEP3.2).

As the photovoltaic (PV) industry continues to evolve, advancements in Japanese photovoltaic inverter standards have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.
