P1: Digital parameters.
P2:Charging indication. This symbol indicates that the solar panel is charging the battery; without this symbol means solar panel can not charge the battery because of low voltage. If the symbol is flickering, means the battery is fully
charged and has entered float charging state.
P3:Indication for solar panel. This symbol indicates that the connection of solar panel is detected by controller; without this symbol means the connection of solar panel can not be detected, or there is no sunshine on the solar panel.
P4:5 bars battery power indication.
P5: Discharging indication. This symbol indicates that controller is in output state, otherwise not in the output state. The flickering of this symbol indicates the damages of internal control devices.
P6:load indication. This symbol indicates that controller is in output state, otherwise not in the output state. The flickering of this symbol indicates overload or the damage of the load.
P7:A stands for the unit of current; H stands for hour.
P8:V stands for the unit of voltage.
