This is the 5th generation of our ACDC18x solar air conditioner series with a new key feature we've had so many requests for - our new "C" model ACDC18C solar air conditioning technology requires no grid connection. Like previous versions, it also needs no batteries, no inverter, no charge controller - just plug in the solar panels and start saving up to 100% on daytime cooling or heating costs. A grid connection can be added to automatically allow operation at night, as well as to provide higher daytime capacity & uninterrupted operation during cloudy or low sunlight conditions.
During the day the ACDC18C can run exclusively on solar power with no AC power or grid connection when solar is strong enough. The maximum speed/capacity will be based on the level of available solar power available. If also connected to AC power source, the unit can run at full speed whenever needed, and will add in just enough AC power, if/as needed, while still primarily using available solar DC power.
