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.
Solar Energy Storage Inverting & Control All-In-One Machine 15

3.2 Output mode
Photovoltaic priority mode: Photovoltaic and battery supply power to the load. With diversified charge
mode and optional output mode, when photovoltaic priority mode is selected, the green solar energy can
be used as far as possible so as to achieve energy conservation and emission reduction. It switches to mains
supply when the photovoltaics is invalid. With the mode, solar energy can be used maximally and electric
quantity can be maintained at the same time. Therefore, the mode is suitable for areas with stable power
grid.
Mains supply priority mode: it only switches to inverter for power supply when mains supply is invalid,
equivalent to a backup UPS. Therefore, the mode is applicable to area with unstable power grid.
Inverter priority mode: it only switches to mains supply in case of undervoltage of battery. With the mode,
DC electric energy is used maximally. Therefore, it is applied to the area with stable power grid.
Mixed functions mode: When the battery is not available or the battery is fully charged, the load is
provided by PV and commercial power, PV maximum output power output。（ Only used for MF）
