Meiden PV inverter SP-100

Meiden Power Conversion
Technologies

Since Meidensha Corporation was founded in 1897, MEIDEN has delivered a variety of its electric products related to power generation, transformation and distribution of electric power and its supervision system to all over the world.
The power conversion system which MEIDEN has developed from 1926 has been evolving with technological evolution of power semiconductor.
Our power conversion technologies are adopted Inverter for electric vehicle, NAS battery system which is for large scale power storage and voltage dip compensator and so on.

Record of PV Inverter

MEIDEN’s first PV Inverter was developed in 1994. We developed the first PV Inverter for large scale solar firm in Japan. MEIDEN has PV Inverters for up to 250kW. Now MEIDEN is a leading company in Japanese PV market. Meiden PV Inverter has exported over 30MW PV Inverters to the world. Meiden PV Inverters were installed with a variety of solar cell which is Polycrystal silicon, amorphous silicon, Hybrid, Tandem and CIS.

Considerable Experience in PV Business

MEIDEN has participated the large scale PV R&D demonstration project with Japanese Government support. This project is installed the largest PV farm (5MW) for demonstration in Japan. And a Power Company, a University and a meteorological agency also participate this project, we are researching the efficient use of power from solar farm. MEIDEN is charge of delivery of PV Inverter, Power conversion system for NAS battery, transformer and supervisory system, and control for stabilizing power.
