Solar Powered Air Conditioner with Backup Battery

Solar Powered Air Conditioner with Backup Battery (9000, 12000, 18000 Btu) is a high-efficiency powerful off grid and on grid photovoltaic (PV) air conditioning system (rating reach to 6W/W, 20.47 Btu/h/w) working 100% with solar energy and consuming less than half wattage than other types of solar air conditioners. The system uses highly-efficient 300W mono solar panels to generate enough electricity during the day to run the air conditioning unit which includes a powerful ACDC hybrid indoor unit (with available capacity of 9000, 12000, 18000 Btu) with a digital display, and a low noise (53~60dB) ACDC hybrid outdoor unit (AC input 208~240V, 50/60Hz, R410A), using a Panasonic pure DC 24V compressor and DC fan & motor.  Furthermore, the system stores excess energy in a high-capacity backup lead acid gel battery (capacity: 2.4kWh, nominal voltage: 12 Vdc, nominal capacity: 200AH, depth of discharge: 70%) for use at night or during power outages, which ensures that the air conditioner can continue to operate even when there is no sunlight available. The system also uses high efficiency Incremental Perturb and Seek algorithm (IPS) which is a type of  MPPT (Maximum Power Point Tracking) control algorithm that is used to optimize the use of the power source that possesses a fluctuating power profile while it prolongs service life of the batteries (MPPT efficiency ≥ 99.5%, whole machine conversion efficiency up to 93%, input PV voltage: 60-145VDC, output voltage range: 280-360VDC, charge mode: 3 stages- fast charge, constant charge, floating charge), and a main disconnect box used to disconnect the power supply from the solar panels to the air conditioner in case of an emergency or maintenance (DC disconnect, AC disconnect, Battery disconnect, PV combiner, IP65 protection degree). Solar Powered Air Conditioner with Backup Battery can help you save tremendous amounts of money on AC bills, offset the initial high installation costs of solar panels and increase the value of your home, while it reduces the energy demand during peak usage and the emission of greenhouse gasses.
