How to Choose Suitable Solar Air Conditioners?

China solar aircon business grows up rapidly in past 2-3 years. There are two main different types of PV solar air conditioners in the market:

  • Off-Grid solar air conditioners

Off-grid means that there is no connection with grid power. Off-grid solar air conditioners can work 100% without grid power. They are suitable for installation sites without grid power supply, or with often power failures. Battery bank is essential for off-grid solar systems because electricity from solar panels is not stable. Solar air conditioners can not be directly driven by solar panels. Therefore, off-grid solar air conditioners can work overnight if there is enough electricity stored in battery bank. Beside battery bank, solar charge controllers are also required for off-grid system. The main function of solar charge controller is to protect battery bank.

Harvest Solar Air Conditioner Limited can provide a “hybrid control box“. With this “hybrid control box”, off-grid solar air conditioners can work under hybrid mode. The power supply will be alternated to grid power automatically upon low battery. When voltage of batteries rise up, the power supply will be switched back to battery bank.

  • AC/DC hybrid solar air conditioners

AC/DC hybrid solar air conditioners can be installed at any sites with grid power supply. 220V/50-60Hz/1Ph grid power is essential for hybrid system. Without grid power supply, hybrid solar air conditioners can’t work. There is an auto power distribution system inside hybrid solar air conditioners. Solar power will be consumed in priority, and the insufficient power will be supplied by grid. If sunshine is strong, most solar power will come from solar panels. In case sunshine is weak, most solar power will come from grid. After sunset, 100% power supply will come from grid. No battery bank and solar charge controllers required for AC/DC hybrid solar air conditioners, so the initial investment of hybrid solar air conditioners will be much lower than off-grid solar air conditioners. Most offices with hybrid solar air conditioners can save 90% electricity bill because they only be used at daytime.

– Low initial investment, short invest return period

– AC/DC hybrid dual power supplies

– Easy and convenient installation

– Use PV power as power priority, utilization rate more than 90%

– Grid AC and PV power interact and auto-distribution, achieve non-stop supply

– Wide DC range (50V-380V)

– Achieve solar panel free combination per installation

– Can work properly under wide climate conditions (T1 & T3)

From above main benefits of AC/DC hybrid solar air conditioners, we found that if there is city grid power available, AC/DC hybrid solar air conditioners will be best solution. If you only use air conditioning at day time, for example, at office, you can save above 90% electricity.

You don’t need to worry about air conditioning during cloudy or rainy days, because even without sunshine, AC/DC hybrid solar air conditioners can still work properly 100% by city grid power.

The most important thing is, without city grid power supply, the AC/DC hybrid solar air conditioners can’t work even under good sunshine.
