Solar inverters, essential for converting DC electricity (produced by solar panels) into usable AC electricity, are imported into Japan at a 0% duty rate. This lower tariff helps keep the cost of adopting solar energy systems affordable for businesses and consumers in Japan.
In Japan, solar panel and inverter manufacturers must adhere to specific certifications to ensure their products meet safety and performance standards. The Japan Electrical Safety & Environment Technology Laboratories (JET) provides certification for photovoltaic power generation systems, including solar panels and inverters.
Key Products and Services: Hitachi offers a wide range of solar inverters, including grid-tied models with high efficiency. Their product lineup features solar inverters for both residential and commercial applications, with outputs ranging from 1.1 kW to 6 kW for single-phase inverters and up to 255 kW for three-phase inverters.
