This paper concentrates on the efficient power outage solution in Nigeria University laboratories using Micro- controller based portable Solar Generator. The design specification include the System Capacity 1000Volts Ampere, modified Sine wave alternating current power, Output Voltage: 220-240 Volts, Output Frequency: 50Hz, battery Bank Capacity: 12Volts/40Ampere-hour, Solar Panel Specification: 30Watts, Pulse width modulator charge controller. During the design a voltage level of 5Volts was fed from preamplifier to the switching Metallic Oxide Silicon Field Effect Transistor that produces the gate current of 0.05 Ampere: Result showed that the oscillator rated output of 5v was obtained at pins 11 and 14 to switch the transistor. Result also showed that the frequency of the oscillator was adjusted and measured until standard frequency of 50Hz was achieved, for the MOSFETs operating at 50Hz and the period of the switching was 0.02sec. The transformer secondary voltage was measured and it gave the expected output of 230v.
