Omron has the power relays required for modern energy generation, storage and use.

As a global manufacturer with key competence in sensing and control technology, Omron provides an array of dependable and highly qualified electro-mechanical components that drive the performance, reliability, and safety of electrical equipment. For commercial buildings which account for a large amount of energy consumption, efforts are being called to reach “zero emission”. In residential, households are increasingly generating power to recharge electrical devices and vehicles. In both cases, this is achieved by the installation of stable renewable energy sources such as solar photovoltaic power generation systems and storage batteries. Omron power relays are integral to building safe and reliable energy systems.
