なく有効に利用することができる。To explain the operation below, normally, the contact Mlt M2a
1M2b is located on the side indicated by the solid line in Fig. 2 as described above, and the power generated by the solar cell (6) charges the battery (1) inside the heat storage layer (3) through the contact M and the contact. M
! The AC power is applied to the inverter αQ via a, and is converted into AC power to supply power to the indoor load (2). In addition, the internal temperature of the heat storage layer (3) is detected by a temperature sensor (not shown), and the heater control panel (7) appropriately controls the temperature of the heater (2).
), the inside of the heat storage layer (3) is maintained at the optimum operating temperature of (1).As mentioned above, the inside of the heat storage layer (3) is heated by a heat medium such as water or air. Since the solar heat collector is circulated by the circulation pump (4), the temperature inside the heat storage layer (3) is considerably raised by solar heat, and the energy required for heating is small.The above is normal operation. However, when the battery (1) becomes overcharged and reaches the upper limit voltage, the upper limit voltage detection circuit OVR inside the voltage detection section (8) operates, energizing the relay 1'-t and closing the contact R1. Drive the electromagnetic contactor to reverse the contact (5) Ml to the side shown by the broken line in Figure 2.
The power generated by the solar cell (6) is not used as a power source for the heater (2) via the heater control panel (7), so that energy can be used effectively. Note that this state continues until the output voltage of the battery (1) drops to a certain value and the operation of the upper limit voltage detection circuit OVH ends, after which the normal state is restored. During this time, it goes without saying that power is continued to be supplied from the battery (1) to the indoor load (b) via the inverter. If over-discharge occurs, the lower limit voltage detection circuit detects this, operates the electromagnetic contactor Ml by the relay connection, and closes the contact M2.
11*M2b on the side shown by the broken line in FIG. 2, that is, M2.
Open * MTo is reversed to closed. Thus, the inverter aQ kt is disconnected from the inverter (1), and the indoor load @ is connected to the commercial power supply αη to receive power supply. Furthermore, during this time, since the solar cell (6) continues to charge the battery (1), the generated power during this time can be used effectively without wasting it.

な向上が図れる利点がある。(6) As described above, the present invention has a heat storage layer whose temperature is controlled by the combined use of solar heat and a heater, and supplies the power generated by the solar cell to the load, and the battery provided in the heat storage layer. The charging system includes an upper limit voltage detection means for detecting overcharging of the battery and a lower limit voltage detection means for detecting overdischarge, and supplies power generated by the solar cell to the heater when overcharged, and supplies power from the battery when overdischarged. Since the power supply to the load is stopped and power is supplied to the load from a commercial power source, the power generated by the solar cells can be used as effectively as possible, and efficiency can be greatly improved. There are advantages.
