What is air-switch?
Air switch, also known as air circuit breaker, is a type of circuit breaker. Air-switch breaker is a switch that automatically turns off as long as the current in the circuit exceeds the rated current. The air switch is a very important electrical appliance in the low-voltage distribution network and electric drive system, such as home power off grid solar system. It combines control and multiple protection functions. In addition to the ability to complete contact and disconnect circuits, it can also protect against short circuits, severe overloads and undervoltages in circuits or electrical equipment, and can also be used to start the motor infrequently.
Why need to connect the air-switch breaker between battery and inverter for the off grid solar system?
It is to protect the battery pack secure connection and better protect the off grid solar system to work well.
How to connect the air-switch breaker for the off grid solar system?
Connection method: Connect the battery pack to the inverter into one line (that is work in series)
