In the investigation of new methodologies andtechnologies, with the purpose of developing a major efficiency inthe Electrical Systems of Power, whilst also finding methods tomitigate or minimize the disadvantages or risks to the environment;they have found ways to innovate new unconventional techniquesof securing the electrical energy to implement to the electricalservice network (to sell to the distribution network) or for autoconsumption(isolated systems of the network).In addition, due that in Ecuador is implementing a new programof efficient cooking, based on the replacement of kitchens andheaters Liquefied Petroleum Gas (LPG) per Efficient ElectricalSystems and between other projects that significantly will changethe curve of daily demand in the country, becoming a problem inregulating.For those two significant reasons, this research proposes anInverter with Sinusoidal Pulse Width Modulation (SPWM), whichtransforms the energy received by the Photovoltaic generators tothe voltage required to inject energy to the Low Voltage grid (LV),with acceptable levels of harmonic distortion (THD).Results show that the work has an acceptable performance. Thedesign can be considered an alternative for current problems,making an analysis and calculation of necessary panels toimplement this energy to the low voltage grid.
