Sumitomo Electric Industries, Ltd. products

The Solar Cell-String Monitoring & Analysis System by PLC (SSMAP™) developed by our company is a system that monitors in real time the amount of electricity generated per string*1 from a mega solar power generation system.

The Sumitomo Electric Group operates its wiring harness business globally to offer various products that meet the needs of the times with superb technologies and quality. The product lineup includes wiring harnesses for transmitting electric power and information in vehicles and products for environmentally friendly HEVs and EVs.

Insulated electronic wires are used for internal including in motors, sensors, power units, etc., of electric and electronic devices. The lineup consists mainly of products that meet the UL and CSA standards.

Optical transceiver modules that support large-capacity/high-speed optical communication; Optical transceiver modules are used in high-speed optical communication systems that require high performance, compact package, and low power consumption. Optical transmission/reception functions are implemented in pluggable modules. These optical transceiver modules comply with various international standard specifications at communication speeds ranging up to more than 100 Gbps. Wavelength division multiplexing (CWDM/DWDM) products for large-capacity traffic are also available.

Redox flow batteries are rechargeable batteries that are charged and discharged by means of the oxidation-reduction reaction of ions of vanadium or the like. They have excellent characteristics: a long service life with almost no degradation of electrodes and electrolytes, high safety due to being free of combustible materials, and availability of operation under normal temperatures. These make the batteries ideal for use in power grid systems. Redox flow batteries are thus expected to serve as a technology to stabilize the power grids that will be needed to expand the introduction of renewable energy including solar and wind power.
