Making two types of PCS to reduce facility cost and minimize power loss
 
  In common solar generation systems with storage batteries, both the solar panels and the storage batteries require PCS for electric power alteration.
  This model has structured component inverter circuits and controllers to combine the functions of the two PCS into one. This has reduced the number of the PCS and coupled transformers needed as well as the man-hours needed to setup them, noticing an approximately 20% reduction of cost examined to conventional systems.*3
  It also saves the solar power in the batteries without the need for AC conversion, lowering the power loss by four to five percent compared to previous models.
 
High-precision output control aids stabilizing the power grid and generation capacity
 
  Fuji Electric is a forerunner in storage battery control for wind generation facilities, with expert expertise gained by undertaking experiments and practical applications ahead of the industry. In this way, FE has developed a control model that achieves a power generation capacity variance (the measurement of power generation capacity fluctuation within a unit time period) within one percent per minute, the highest level in the world. The new product can be equipped with this control model*4, which provides support for the stabilization of power grid systems and generation capacity.
