Analisis Produksi Energi dari Inverter pada Grid-connected PLTS 1 MWp di Desa Kayubihi Kabupaten Bangli

Inverter is a very important component of a gridconnected PV plant due to its function to convert DC power output of the PV module to AC power. Inverter is built from many components to support its operation so it is the most complex component in a PV systems. The 1 MWp grid-connected Kayubihi PV Plant uses 50 units of 20 kW inverter. This research is aimed to obtain inverters performance also the effect of string array position to energy production of the plant. Energy production analysis of the plant is conducted by mapping the energy production percentage of each inverter, then inverter with the highest energy production percentage is nominated as the reference to measure the performance of other inverters. The analysis considers string array location which connected to the inverter too and also based on the site condition of PV location. It is found that that the highest energy production is shown by inverter 44-E5 with energy output of 17.827 kWh and the lowest is inverter 8-D3 at 8.898 kWh. The highest average energy production is inverter 44-E5 at 72,47 kWh/day, and the lowest is inverter 11-C5 at 39,26 kWh/day. Based on the analysis, it can be concluded that all inverter in Kayubihi PV Plant has its energy production greater than or equal to 75% of the optimum energy output of string array and the inverter 29-B9 has the highest energy production percentage.
