| Message: | 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. url:http://www.royalstarhomeappliance.com |
