The photovoltaic loading management system has been designed according to weather conditions. The performance analysis of the PV loading management system based on weather conditions is presented in this paper. The load management mechanism works as follows: when the charging current drops but the battery capacity is still large, the high load option is maintained. When the charge current decreases and the battery capacity is medium, the loading option will switch to medium load. If the charging current drops lower and the battery terminal voltage is lower than 22.3 Volts, then the low load option will be selected. The PV current fluctuation affects the battery voltage, which causes a reduction in the maximum load that the loading management system can serve. The charging current can be estimated from the difference between PV current and recharging current. The analysis results show that an increase in the supply of renewable energy generation can also be done on the demand side. Therefore, it is necessary to apply PV loading management to improve and maintain the continuity of electricity supply from solar sources in the future .
