Air conditioner, combine with refrigeration technical and arts, consider air conditioners reliability and stability function, and also to consider harmony with room decoration (especially the type connecting to family: wall-mounted, floor standing, cabinet). And always use the latest surface handicraft; make you feel comfortable and suitable for air environment, the room space showed more style, and more nature fresh.
Air conditioner use world famous compressor from Japan, hydrophilic aluminum foil, super-quality internal threaded copper pipe and other key parts, add over 10 years technology and experience, the trip technical team, and consummate quality check, manufacturing hangning with high-performance effect.

Dual power On Grid Hybrid Solar Air Conditioning system,the power form solar panel priority supply directly to indoor & outdoor fan motor and compressor. When the solar power is not sufficient,by equipped with dual PV MPPT tracking system,the system automatically switch to run by grid power, thus achieved the AC/DC power supply interaction, and uninterrupted supply power to air conditioner, ensure the system high efficiency up to SEER 36;
Wide voltage design, free combination of solar panels,make our system not limited by the installation space. Minimum only two solar panels required to run our system,maximum power of solar panels is 2700 W

1.AC/DC dual power supply
2.High energy efficiency: maximum up to SEER 36;Even if there is no sunshine,up to SEER 21.
3.Convenient and quick installation, no longer require solar controller, battery and inverter
4.Using solar power priority,solar power utillization rate more than 95%
5.Solar power/grid power supply interaction,achieve uninterrupted power supply;
6.Wide voltage design, free combination os solar panels, not limited by installation place
7.Compliant to all climate condition.

New refrigerant R410A has stabilization, innocuity and more efficient characteristic, due to not including chlorine element, will not destroy the ozonosphere. In addition, use new refrigerant will take advantage on air conditioners performance .

The use of permanent magnet rotor produce the magnetic field without the power turn on, it can save the energy, make the whole system more efficient, and would be more steady while working.

Adopting the high-grade inner-groove copper pipe to improve the heating and anti-defrosting efficiency of the heat-exchanger.

Keep the system stable and powerful but quiet with long used life span.

Ralstar Solar Air Conditioner Co.,Ltd. never stop working on out mission to create a sustainable future
Enviromental protection and the sustainable use of natural resources are both our goal and motivation. The increasing energy consumption worldwide by means of fossil fuels implies strong economic and environmental costs. As heating accounts for 56% of the world's total final energy consumption, it becomes extremely important to switch to renewable energy. Compared to other renewable energy sources,solar air conditioner contributes considerably to the energy supply.
Being as a subsidiary of Royalstar group Royalstar Solar Air Conditioner Co.,Ltd.,one of the most important renewable energy companies in China ,Royalstat solar air conditioner relies on the technologies and know-how of its' strong partners form the largest solar thermal markets:China and Europe,and give its best to supply high-quality solar energy products with advanced technologies to customers all over the world.
Royalstar group Royalstar Solar air conditioner Co.,Ltd is the first venture that develops.manufactures and distributes market oriented solar solutions in China. And its business scope has now expanded to solar thermal,solar air conditioner and air source heat pumps.

1.Can i buy solar air conditioner only from you, and buy other accessories from other supplier?
RE: Yes , you can buy solar panels, deep cycle JEL batteries , solar controllers, batteries changers and power adapter from other supplier.
2.What will happen when batteries is not enough to drive air conditioner ?
RE:Dual power On Grid Hybrid Solar Air Conditioning system,the power form solar panel priority supply directly to indoor & outdoor fan motor and compressor. When the solar power is not sufficient,by equipped with dual PV MPPT tracking system,the system automatically switch to run by grid power,
3.What is the voltage range for solar air conditioners?
RE: The rated voltage range is 208~240V, 50/60 Hz
4.How many watt solar panel we need to drive solar air conditioner?
RE: It is depend on the Btu and work time you demand.
5.What is the function of batteries?
RE: Battery is the energy bank to reserve electricity energy.
