What Is The Off-grid Solar Air Conditioner

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.

How does the off-grid solar air conditioner working?

For the off-grid solar air conditioner, it added the IPS - solar aircon controller and battery based on the ACDC Hybrid solar aircon system. On the sunshine day, the solar energy will be used for the A/C unit running, the sufficient energy will be charged to the battery through the IPS. When solar energy less the air conditioning energy consumption, it will take the insufficient energy from solar backup automatically. At night it will use battery energy. When there is no sunshine and the battery does not have energy, you can connect with grid power.

For example:
The air conditioner energy consumption is 1000W. When solar energy is 2000Kw, the system will take 1000W for the A/C unit running, 1000W for charging the battery. When solar energy is 1000W, it will be used for running the A/C unit and stop charging the battery. When solar energy is 400W, it will use the 400W as the priority choice, another 600W from the battery.
