What is the off-grid solar air conditioning
Off-grid solar air conditioner system is a product developed from the existing ACDC Hybrid solar powered air conditioner according to market demands and customer feedback. ACDC air conditioners can only use solar energy during the day and must use grid electricity at night, when the air conditioners are not used during the day, the solar energy is wasted. Off-grid air conditioners perfectly solve these shortcomings and can customize a system with specific working hours according to the actual needs of customers.
The working principle of off grid solar air conditioning.
Sunpal off-grid solar aircon supports solar energy, grid power, and battery.
When solar energy = aircon consumption，the solar energy will be used for aircon running directly，it will not charged to the battery or through the battery to run the A/C unit.
When solar energy > aircon consumption, some solar energy will be used for the A/C unit running, some solar energy will be charged to the battery automatically.
When solar energy < aircon consumption, It will use solar energy as the priority choice， the insufficient energy will takes from the battery automatically.
When solar energy & Battery < aircon consumption, you can connect the Grid for 24H working.
