Overview

OIG Power is a Czech clean-energy company that develops and manufactures home energy storage and renewable-energy systems. Its official website presents the company as a provider of "clean energy" solutions built around the idea of household energy independence, cost savings, and security during grid outages. The company positions its products against the backdrop of rising energy prices and the broader trend toward decentralized, renewable electricity generation. The company's flagship product is the CES BATTERY BOX, described on its website as a unique three-phase system with a Czech patent and Czech manufacturing. The product is marketed as a way for households to operate their own small power plant using renewable sources, taking advantage of the roughly 1,500 hours of sunshine per year typical in the Czech Republic. OIG Power emphasizes energy self-sufficiency, protection against distribution-grid failures, and long-term savings on energy bills. OIG Power supports its hardware with mobile and web applications. The site lists an application for remote control of all BATTERY BOX models, referred to as the ČEZ Battery Box app, and a separate home-screen app for the BATTERY BOX Queen system that displays real-time data. The company also maintains a blog and a support section, and offers an English-language version of its site alongside the Czech original. OIG Power is registered as a Czech company. Public evidence about its founding date, ownership structure, executives, and financial details is limited, and the company does not appear to be listed on a stock exchange. Its public identity is centered on the CES BATTERY BOX product line and the theme of household energy independence.

History

OIG Power is a Czech company operating in the clean-energy and home energy storage sector. Its official website describes the company's motivation as stemming from the growing dependence of households on electricity, the environmental impact of unsustainable energy sources, and the sharp rise in energy prices. According to the site, these factors led the company to develop an accessible solution for every household, resulting in the three-phase CES BATTERY BOX system. The company presents the CES BATTERY BOX as a unique product with a Czech patent and Czech manufacturing. The system is designed to let households produce their own energy from renewable sources, with the website citing an average of 1,500 sunshine hours per year in the Czech Republic as a basis for solar generation. OIG Power markets the product around four main benefits: energy independence, cost savings on energy, home security during grid outages, and the use of clean energy. OIG Power has also developed software to accompany its hardware. The website lists applications for Android and iOS, including an app for remote control of all BATTERY BOX models and a home-screen app for the BATTERY BOX Queen system that provides real-time data. The company maintains a blog and a support section, and offers an English-language version of its website. Specific details about OIG Power's founding, corporate history, ownership, and leadership are not provided in the available evidence.
