The photovoltaic direct-drive control solution directly drives the heat pump through photovoltaic power generation, achieving zero energy conversion loss, maximizing the use of solar energy to meet cooling/heating needs, and reducing grid dependence and electricity costs. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. In this setup, the direct current (DC) electricity generated by the photovoltaic panels powers the. The DC electricity generated by solar panels is boosted through a voltage module and directly supplies power to the DC inverter compressor. Efficient and Stable Photovoltaic.
