In summer, the power consumption of an air conditioner is large, as is photovoltaic power generation. The Gree Photovoltaic Direct-driven Inverter Multi VRF System combines the characteristics of photovoltaic power, making sure that the consumed electricity of units matches the photovoltaic power generation to achieve zero electricity charge.
In this paper, PV generation is utilized with a battery energy storage (BES) for an air conditioner to reduce the impact of energy consumption from utility grid. Recently, air conditioning units are adopted with variable speed drive (VFD) that creates peaky nature of the input grid current due to the AC-DC conversion.
By adopting advanced photovoltaic direct-driven technology, the system can achieve power generation by utilising solar power while consuming electricity, prioritising the use of photovoltaic power.
In rated engineering proportion, the power amount that Photovoltaic Direct-driven Inverter Multi VRF System gets from the grid is balanced with the power amount that the system delivers to the grid in each day, each month, each quarter, and each year. Generally, power consumed from the grid is zero.
