PURPOSE: To make good use of solar energy, by constituting a system that modulates an output variation related with solar-light power generation. CONSTITUTION: An inverter system of solar-light power generation is made up of a solar battery 1, a DC/DC converter 2, a DC/AC inverter 3, a battery 4, a control system 5, and a high-speed switch 7. A charging state is detected from the battery 4 to control the operation of the inverter system of solar-light power generation, and the switching to the commercial system power is carried out under control. As to the parallel operation with the battery 4, limiting values for the discharging current and discharging power are previously set to judge the switching timing of to the commercial system power. |
