How it Works
ACDC solar air conditioners are engineered to run directly on solar power during the day. The solar panels connect to the outdoor unit, supplying DC power for the compressor and fans.


100% Solar
PV power meets the minimum operating power of the compressor, the air conditioner can start and powered by solar energy only, even the grid off. 100% energy saving.
Grid & Solar
When the sunlight is weak, such as in the morning or on a cloudy day, the system prioritizes using the electricity generated by the solar panels. If the solar power isn’t enough, the system supplements the needed power with electricity from the grid.
Grid Power
At night, the system automatically switches to grid power. The compressor and control circuits are designed to handle voltage fluctuations without affecting performance.

Air Conditioner Maintenance
To keep your DC inverter air conditioner running smoothly and efficiently, follow these maintenance tips:
Regular Cleaning
1. Filter Maintenance: Check and clean air filters monthly. Replace them if they’re very dirty. Clean filters improve airflow and efficiency, reducing energy consumption.
2. Dust Removal from Coils and Fans: Use a brush to clean dust from the evaporator and condenser coils and fan blades. This prevents dust buildup that can affect performance.
3. Outdoor Unit Care: Keep the outdoor unit clear of debris like leaves and dirt. Ensure proper airflow around the unit to prevent overheating.
Professional Maintenance
4. Routine Professional Servicing: Have a licensed HVAC technician inspect and service your air conditioner annually. They will check refrigerant levels, electrical components, and other vital parts to ensure optimal performance.
5. Condensate Drain Inspection: Clean the condensate drain line at least once a year to prevent clogs that can cause water damage and reduce efficiency.
Operational Tips
6. Monitor Refrigerant Levels: Low refrigerant levels can cause the system to work harder, increasing energy consumption and potentially damaging the compressor. Have a professional check refrigerant levels regularly.
7. Check Electrical Connections: Make sure all electrical connections are tight and free of corrosion. Loose connections can lead to system malfunctions.
8. Upgrade to a Programmable Thermostat: A programmable thermostat allows you to set temperature schedules based on your routine, optimizing energy use and improving efficiency.
By following these maintenance tips, you can ensure your DC inverter air conditioner operates efficiently, keeping you comfortable while minimizing energy costs.


Solar Panel Maintenance
To keep your solar panels in top shape and extend their lifespan, regular maintenance is essential. Here are some key tips:
Cleaning
1. Cleaning Frequency: Clean your solar panels at least twice a year. Depending on your location, you may need to clean them more often due to factors like dust or pollen. If you live in an area with frequent rain, you may not need to clean them as often since rain can help wash away dirt and debris.
2. Cleaning Methods:
– Use a soft brush or garden hose to remove loose dirt and debris. Avoid using abrasive materials or harsh chemicals, as they can scratch the surface of the panels or leave behind residues that can damage them.
– If necessary, use a microfiber cloth with water or a mild glass cleaner to wipe down the panels. Avoid using high-pressure washers, as they can damage the panels.
3. Best Time to Clean: Avoid cleaning your solar panels during peak sunlight hours when they are hot, as this can cause them to crack due to sudden temperature changes. Early morning or late afternoon is the best time to clean your panels.
Inspections
4. Routine Inspections: Regularly inspect your solar panels for dirt buildup, physical damage, or shading from nearby objects such as trees. Also, check for signs of wear on wiring and connections.
5. Professional Maintenance: Have a qualified technician inspect your solar panels annually to ensure that all components are in good working order and address any issues before they become serious problems.
Additional Tips
6. Clearing Debris: Keep the area around your solar panels clear of branches, leaves, or other debris that could block sunlight and reduce efficiency.
7. Managing Snow and Ice: In snowy climates, ensure that snow does not accumulate on your solar panels. Gently clear snow when necessary and avoid using hot water, which could crack the panels.
By following these maintenance tips, you can ensure that your solar panels operate efficiently and effectively, extending their lifespan and maximizing energy production.
