As is known, the potential of Indonesia’s natural resources is quite high in solar energy if it is utilized to the best of its ability. By utilizing this energy, the use of electrical energy through PLN will be reduced or assisted in terms of electricity supply so that it can reduce the supply of existing loads. The effect of temperature from the photovoltaic system has an impact on the current and voltage output so that the resulting output will be optimal or not. Based on the data irradiation also affects the power output by the inverter. The inverter will also work properly when the standard value of the inverter specification will work when the minimum voltage value is in the range of 400V-800V and reads well above 800 V according to the experiment and the current is stated to be 12.5 A to 33 A with the data obtained above. So that the performance of the inverter is in its maximum condition, but when the irradiation condition decreases, the performance of the inverter will decrease, which can be seen from the power generated. The measured temperature based on the input data from the inverter shows a value above 25 °C will make the inverter work according to standard. When the work efficiency of the inverter decreases, the output power will not be optimal. but when the parameters of the PV system start from temperature to optimal irradiation level, the input and output of the inverter also work optimally.
