3. Operating Mode
3.1 Charging mode
1. PV priority: PV system is prioritized for battery charging, only when the PV fails, mains
charging is activated. Making full use of solar energy to generate power during the day
and switching to mains charging at night keep the batteries charged. This mode is
applicable to the areas where the grid is relatively stable and electricity is more expensive.
2. Mains priority: Mains power is prioritized for battery charging, only when the mains
power is not available, PV charging is activated.
3. Hybrid charging: PV and mains hybrid charging. PV MPPT charging gets the priority. When
PV energy is insufficient, mains starts to charge. When the PV energy is sufficient again,
the mains stops charging. This is the fastest way to charge, suitable for areas where the
grid is unstable, and provides an adequate back-up power supply at all times.
