This research developed power sharing methods between inverters in the PV microgrid. The regulator of microgrid operation mode while using the back-up battery in every distributed generation during islanding condition needs to be done in order to maintain continuity of power supply from every generator to meet the power load. Arrangement of microgrid operation mode is done by adjusting power-sharing supply distribution between generators which sourced from the battery and utilizing energy source from solar radiation optimally when the sun exist. The study was conducted by comparing three microgrid operation mode simulations; stand alone, equal output power, and equal battery level. The simulation results show that the distribution of power sharing method between generators, based on equal battery level, is better than equal output power, where on equal battery level, the Power Distribution Index (PDI) = 100% while, in equal output power, PDI = 94.6%. Meanwhile forthe Battery Charging Index (BCI) both methods give the same result of 100%.
