Abstract :
In an era of industry 4.0, demand for electrical energy is more environmentally friendly, which is less likely to cause pollution and reduce the negative impact on the environment. Renewable Energy is one of the solutions. One example is using PLTS. However, the output of PLTS is in the form of direct current, while electrical loads that are often used daily, such as household appliances, require AC voltage. The equipment used to convert direct current into the alternating current is an inverter. Therefore, the design of a pure sine wave inverter using a microcontroller was chosen because it produces an output that resembles the PLN voltage output. The microcontroller functions as the core of the circuit so that the output from the inverter can be adjusted using only 1 component that can work multifunctional. Arduino Pro Mini Mini V3ATMega328 is the type of microcontroller used. The output wave results obtained are not as expected. The resulting voltage waveform is still in the form of SPWM (Sine Pulse Width Modulation). Possible errors occur in the capacitor section in the feedback section, before feedback the transformer output will pass through the LC circuit filter to convert SPWM into a pure sinusoidal wave. But the certain results obtained have been able to work on several examples of certain electrical equipment loads such as fans and 40-watt lamps
