1.Application Scenarios with Only Mains Power but No Photovoltaic
When the mains is normal, it charges the battery and supplies power to the loads
When the mains is disconnected or stops working, the battery supplies power to the load through the power module.
2 .Application Scenarios with Only Photovoltaic but No Mains PowerDuring the day, the photovoltaic directly supplies power to the loads while charging the battery
At night, the battery supplies power to the loads through the power module.
During the day, the mains and photovoltaic simultaneously charge the battery and supply power to the loads.
3 .Complete Application Scenarios
At night, the mains supplies power to the loads, and continues to charge the battery, if the battery is not fully charged.
If the mains is disconnected, the battery supplies power to the loads.
