3.Operating Mode
3.1 Charge mode
1. Photovoltaic priority:
in photovoltaic priority charge mode, mains charge is started only when photovoltaics
is out of work. Make full use of solar energy for power generation in the daytime and transfer to the mains
supply for charge to maintain electric quantity of the battery. It is suitable for areas with relatively stable power
grid and relatively expensive electricity price.
2. Mains supply priority:
mains supply is to charge the battery preferentially and the photovoltaic charge can
be started only when the mains supply is valid.
3. Mixed charge:
with mixed charge through photovoltaics and mains supply, photovoltaic MPPT charge is
used preferentially. In case of insufficient photovoltaic energy, the mains supply is used for supplement. In case
of sufficient photovoltaic energy, mains supply stops charge. Electricity can be charged fastest with the way,
which is suitable for the area with unstable power grid, so as to supply sufficient backup power supply at any
time.
4.Only solar:
only photovoltaic charge is used, no mains supply is started. This way can save the energy at most.
The electric energies of battery are all from solar energy. This way is suitable for areas with good light condition.
