Two functions: Solar mode & UPS mode
Solar mode and UPS mode: According to the actual situation to choose

Solar mode -- DC priority [-]
When mains electricity and battery voltage are normal, inverter convert DC to AC -- battery supplying electric power for loads; when batteries voltage is too low, inverter auto-switch to that mains supplying electric power—mains electricity cannot charge the battery; when battery have been fully charged by solar panel, inverter will auto-switch to that battery supply electric power.

UPS mode -- AC priority[o]
When mains electricity is normal, inverter will switch to that mains supplying electric power for loads, the batteries are charging by mains and PV panel at the same time. If mains are breakdown, inverter auto-switch to that battery supply the power for loads.
