This controller takes solar power as a input and the power is converted into Varying DC power by solar PV modules depending on changing sun intensities During the day time. Using advance technology ,the varying DC power is converted into A.C power That drives an AC motors or pump set directly. The equipment is micro controller based and operated with software for digital control of all parameters, fault finding diagnostics. Inbuilt Controller with the function MPPT ( Maximum Power Point Tracking).

AC Speed Controller Rotational speed N of an induction motor can be shown by the expression (1). When the voltage applied to the motor is increased and decreased, the slip s changes, then the rotational speed N will change N= 120·f ·(1-s)/P · · · · · · · · · · (1) N: Rotational speed [r/min] F: Frequency Hz P: Number of poles of a motor S: Slip In the case of an induction motor as shown in Fig. 4, a stable range and an unstable range exists in the Rotational Speed - Torque curve. Since it is impossible to reliably operate in the unstable range, simple voltage control (open loop control) is limited to controlling the speed in a narrow range like, N1~N3 in Fig. 5. To make it possible to operate reliably even in the above-mentioned unstable range, it is necessary to detect the rotational speed of the motor and use a voltage control mechanism (closed-loop control) that reduces the speed error when compared to a set value.
