Catalog

From micro grid to mega solar

We offer a wide lineup from decentralized grid connected small capacity inverter to large capacity power generation system.
We also offer inverters compatible with fuel cells and storage batteries. We have been selling various power converters as well as power semiconductor devices and their application equipment for many years.
Recently, we have also been focusing on consumer power control devices and offer a wide range of products from small capacity to large capacity for power conversion.

Solar inverters connecting to the grid must have high reliability, high quality, and high efficiency, especially in government agencies and electric power companies. We use our "manufacturing knowledge" to comply with the grid interconnection technology regulations of each country, and original efficient circuit technology. We offer global maintenance service.
We strive to promote new energies and contribute to the stable operation of decentralized power systems.

Indoor standalone unit Large capacity solar inverter for solar power system

To meet the global expansion of mega solar power plants, we developed a single-unit large-capacity solar inverter.
We expanded the product lineup with "high-efficiency power type".
We offer 2 to 4 MW class systems.
Supports FRT requirements and solar inverter output control function (standard) by remote control (communication).

Features

  • Highest Efficiency with built-in Isolation Transformer Models

    Achieves 96.6% (100kW) / 96.8% (250kW) / 97.2% (500kW) for maximum efficiency.
  • Operation voltage range: We have two series: DC330~750V (rated DC 500V) and DC440~1000V (rated DC 650V).

  • Smallest footprint of its class

    We managed to reduce the footprint for 100kW to 500kW models.
  • Easy maintenance

    Standardized maintenance and parts.
  • Noise filter at the input/output circuit equipped as standard

  • Constant power factor control function equipped as standard

    Suppresses grid voltage by controlling operating power factor.
  • No junction box required (1000V series)

    Equipped with built-in input breaker so no junction box required.
  • Remote output control function equipped as standard

Solar Inverter
(for outdoor solar power system, forced air cooling system)

Forced air cooling type solar inverter for outdoor integrated solar power system

Greatly reduces running costs and maintenance costs by using forced air cooling system.
Supports FRT requirements and solar inverter output control function (standard) by remote control (communication).

Features

  • Greatly reduces running costs and maintenance costs by using forced air cooling system

  • Conversion efficiency maximum 96. 8%

    Highest Efficiency with built-in isolation transformer.
  • Noise filter at the input/output circuit equipped as standard

  • Constant power factor control function equipped as standard

    Suppresses grid voltage by controlling operating power factor.
  • Easy installation and construction

  • Remote output control function equipped as standard
