However, the amount of power shortage that is used during the daytime is stored in the battery by the power of the nighttime power rate. 2. At night, SW is set to N by the timer built into the control circuit, and the electric power supplied to the electric products and the like is from the commercial power source of an inexpensive night fee. And so on, and even if it is not, 1. The clean energy system, which is affected by weather conditions, is very costly because the safety factors such as rain, cloudy weather, changes in sunshine hours due to the four seasons, wind power, etc., which are usually considered, are included in the capacity calculation. In this system, there is no power supply from the battery at night, and the amount of power consumed during the day is charged to the battery by the night wind power generation and the night commercial power supply (solar cells generate power only during the day). It only needs to be installed. 2. Aside from the calculation of the break-even level, surplus power can be sold to the daytime power company by increasing the inverter capacity, control circuit, battery capacity, etc. 3. It can be designed according to the budget, such as the installation cost of solar cells, and can contribute to society against the increasingly shortage of power costs. 4. Unbalanced power consumption during the day and night is reduced. And so on. 5. In the case of equipment with sufficient margin for in-house power generation, reverse power flow is possible with the conventional meter-based lighting contract as it is, instead of the time-based lighting contract shown in Fig. 4. In that case, depending on the function setting in the hybrid switchboard, it is unnecessary to switch the electric power supplied to the electric appliances and the like by the day and night timer. 6. Solar cells and under-generating capacity of the wind power generator aside, battery capacity, inverter - E 1 of the capacity of such data in FIG. 4 to E N
When the load is overloaded. It can also be equipped with a function to automatically switch the overload section to an electric power company distribution line without any interruption (day or night). If the storage battery capacity and the inverter capacity are obviously insufficient at the beginning of the installation,
Select the contract with the electric power company by the profit and loss calculation. In that case, reverse power sale is inevitable.
