Solar controller 10a, a represents what
10A indicates that it can control the maximum current is 10 amps, the use of the load can not be greater than this current.
In addition, the general controller will be marked as single-phase or three-phase power, according to P = UI (power = voltage * current) this formula, you can infer the corresponding power, in the choice of output devices (such as pumps) can not exceed this power.
A (Ampere) is the basic unit of current expressed in the International System of Units, referred to as Ann, Symbol A. 10A refers to the controller can control the output device maximum current of 10A, select the load device when the device current can not exceed this value
A, represents the current. Indicates the current that is allowed to pass during operation of the controller.
