Hitachi Appliances Inc will begin to sell a residential photovoltaic (PV) power generation system consisting of its power conditioner, base and fittings and other company's PV power module under the Hitachi brand Aug 20, 2012.

Hitachi Appliances will deal with three types of modules. Two of them are CIS-based PV battery modules manufactured by Solar Frontier K.K., and the other one is a monocrystalline silicon-based PV battery module manufactured by Suntech Power Japan Corp. It is possible to choose a module according to installation site, roof size and shape, etc.

Two kinds of power conditioners can be combined with the system. Their rated capacities are 4.0kW and 5.5kW. Hitachi Appliances used its own inverter technologies such as for lowering losses associated with electric components and circuits. As a result, both of them have a conversion efficiency of 96%. Also, the company employed the "HI-MPPT (maximum power point tracking)," which operates the PV generation system by seeking for an appropriate timing for the peak of power consumption in response to changes in sunlight.
