Gree is dedicated to the research and reformation of air conditioning technology. The Gree Photovoltaic Direct-driven Inverter Multi VRF System breaks through tradition, innovatively combining photovoltaic power generation with the power consumption of an air conditioner.
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. Compared to traditional photovoltaic systems, energy wastage during multiple commutation of the alternating current and direct current is eliminated, improving energy efficiency by 6% to 8% and bumping the photovoltaic utilisation ratio up to 99%. The innovative Maximum Power Point Tracking (MPPT) technology can track and control the maximum power point status of photovoltaic power generation, achieving maximum utilisation of photovoltaic power.
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 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.
When photovoltaic generated power is equal to the air conditioner consumption demand, the air conditioner consumes photovoltaic power only.
When photovoltaic generated power is less than the air conditioner consumption demand, the air conditioner will draw power from the grid in addition to the photovoltaic power generation system.
When photovoltaic generated power is more than air conditioner consumption demand, photovoltaic power will give priority to the air conditioner, and then the residual power will be sent to the grid.
When the photovoltaic power generation system does not work, the system is powered by commercial power. In this situation, the system operates equal to an inverter VRF system.
When the air conditioner stops operation, the power generated by the photovoltaic power generation system is sent to the grid. In this situation, the system operates equal to a power station.
