[0024] In order to specifically illustrate the present invention, the following combination figure 1 The present invention is further explained.
[0025] Reference figure 1 , The new solar water heater includes: solar photovoltaic battery pack 1, super capacitor pack 3, heat preservation tank for storing hot water 6, air energy heat pump system 7 ( figure 1 The system shown is driven by a DC motor) and a power adapter 8 (AC input and DC output).
[0026] The solar photovoltaic cell group 1 is connected to the super capacitor group 3 through the A switch assembly 2 to form a charging circuit. When there is light, the solar photovoltaic cell starts to output, the super capacitor is charged, and the voltage gradually rises. When the controller detects that the charging voltage of the super capacitor bank 3 exceeds the set maximum value through the voltage sensor 4, the A switch assembly 2 is disconnected and charging stops.
[0027] The super capacitor bank 3 is connected to the DC mot...
