Gree has been working on the research and reformation of air conditioning technology. Gree Photovoltaic Direct driven Inverter Multi VRF System breaks through tradition, combining photovoltaic power generation with power consumption of air conditioner for the first time.
By adopting advanced photovoltaic direct-driven technology, the system can achieve power generation by utilizing solar power while consuming electricity and ensure utilization of photovoltaic power in priority; compared with traditional photovoltaic system, energy wastage during multiple commutation of alternating current and direct current is eliminated, with energy efficiency improved by 6%-8% and photovoltaic utilization ratio up to 99%; besides, the innovative MPPT (Maximum Power Point Tracking) technology can track and control the maximum power point status of photovoltaic power generation, so as to achieve maximum utilization of photovoltaic power.
In summer, power consumption of air conditioner is large and photovoltaic power generation is relatively large as well. Gree Photovoltaic Direct-driven Inverter Multi VRF System, combining the characteristics of photovoltaic power, makes sure that the consumed electricity of units matches with the photovoltaic power generation so as 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, 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 photovoltaic power generation system doesn't work, the system is powered by commercial power. In this case, the system equals 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 case the system equals to a power station.
