Generally, an off-grid solar power model was applied widely to areas with no electrical network exist for storing energy during the day and using it at night. This model uses a central inverter for several photovoltaic modules, which produces high and dangerous DC voltages, and also has large sizes and high prices. In this study, on-grid solar system model based on micro inverter is built that can use for purposes of teaching material that directly connected to the electrical grid with no batteries or chargers, thereby reducing investment costs and suitable to be applied in the community. Small sized micro inverters can be installed directly under the solar module and also generate AC voltage that can be directly used for own use or sold to PLN. The module that is built is an on-grid solar photovoltaic 300 wp model  using a 300 watt micro inverter and equipped with an electric load in the form of a light bulb and socket outlet. For data retrieval, this model is connected to the PLN network through household electricity customers with 1300 VA power. The result of measurement this solar power model cangenerate the maksimum electric power is 142.37watt and can distribute electric power to PLN  around 115,41 watt. This PLTS model is ready to be use  for purposes of teaching material and also for promotion to community  about model of on-grid PLTS that having economy value so can support goverment in achieving the national target in the renewable energy field.
