Operating modes
3.1 Charging mode
1)
PV priority:
PV module will charge the battery preferentially, and the battery is charged by the
Mains only when the PV system fails. During the day, solar energy is fully used to charge, while at
night, it converts to the Mains. This can maintain battery level, and is ideal for areas where the grid
is relatively stable and electricity price is relatively high.
2)
Mains priority:
The Mains supply is preferentially used to charge the battery. Only when the Mains
fails, the PV charging can be activated.
3)
Hybrid charging:
PV and mains hybrid charging. PV MPPT charging is a priority, and when PV
energy is insufficient, the mains supply supplements. When the PV energy is sufficient again, the
mains stops charging. This is the fastest charging mode, suitable for the areas where power grid is
unstable, providing sufficient backup power supply at any time.
4)
Only Solar (Only Solar):
Only PV charging, without Mains charging. This is the most energy-
efficient way in which battery is charged only by solar panels, and is usually used in areas with
good lighting conditions.
