· OIH-100 is an indoor-monitoring system to enable the user to confirm the amount of solar-ray photovoltaic power generation and amount of electricity consumption at home where the solar-ray photovoltaic power generator is installed. This equipment is referred to as IHD(In-Home Display). 

· OIH-100 collects the following information and provides it to the user by communicating with MMC-100, solar-ray measuring instrument on wireless basis. 

- Amount of solar-ray photovoltaic power generation (amount of electricity generated by solar-ray photovoltaic power generator at home) 

- Amount of electricity consumption (amount of electricity consumption at home) 

- Amount of electricity sales (amount of electricity sold to electricity company at home) 

- Amount of purchased electricity (amount of electricity sold to home by electricity company) 

- Offering of the function to store data by day/month/year unit, and statistical data 

- Function to calculate the consumed electricity 

- Offering of efficient electricity-saving method 

· OIH-100, solar-ray monitoring system provides the electricity-saving habit owing to its availability to confirm the consumption and generation of electricity every day at home where the solar-ray photovoltaic power generator is installed. 

· OIH-100 simplified the menu configuration so that the user may use the system conveniently, and its installation is easy owing to operation based on wireless communication. 

· OIH-100 can be provided at low price compared to other competitors through efficient platform design.

Case of application

· OIH-100 is being supplied to solar-ray photovoltaic power plant in Japan since 2012.
