2.5 Working principle

Energier Apollo can be set to power backup mode or solar mode.
Power backup mode
When Energier Apollo is set to "Power Backup Mode", it will power AC load with grid or generator
as first priority in case AC input is present. When the AC input is not present, it will switch to inverter
mode automatically, then AC loads will be powered by solar and battery.
Solar mode
When Energier Apollo is set to "Solar Mode", solar energy provides power to the AC loads as first
priority. If solar energy is not sufficient to power all connected AC loads, battery will supply power
to the load at same time. Grid provides power to the AC loads only when battery voltage drops to
"inverter to grid" threshold. At that situation Energier Apollo will be back to invert mode when battery
voltage increases to "grid to inverter" threshold .Both threshold values are preset in the configuration.
Please refer 6.3.2 for details.
Notice: AC charger function should not be disabled in any working mode, when user
wants to charge the battery from grid or generator.
